I would love to try to delid that 5900x and see if it's a contact issue. Maybe there's an internal issue where the chip is barely touching lid. Or maybe try turning one of the CCDs off amd try running at stock settings.
So the first 2 that get stuck on Dram light, I think you are correct mostly...I've seen this a bunch of times...It usually happens when the SOC voltage gets set too high and damages the memory controller...It really doesn't like getting overvolted too much unless you have extreme cooling...
for the chips that do boot in to bios you could try turning cores off, first try to see if it works ok with only 2 cores then enable 4 and so on to find out maybe a 6 core can work fine with 4 cores

I agree....cooling IS an issue with the R5-3600 if you use the pitiful cooler supplied with the CPU. With a good cooler that keeps it below 65C no matter what...mine has been absolutely reliable...so far.(knocks on wood)
If you install poorly it is generally VERY easy to tell why it is broken. Bent pins or massive damage to the socket itself or conductive thermal paste in the socket for example. Thermal loads could cook a chip in theory but in general its not something that will generally cause a chip to fry since people will normally notice something is wrong even if they arent tech literate. In reality though the truth is that no QC is perfect and every company makes lemons or has broken parts slip through the cracks. Or even parts that pass QC if only barely so they fail quickly. Thats one of the reasons you generally want to stress test a new system for a bit after you build it. If something passed the basic QC at the factory but has an issue when its ran hard for a long period its best for it to burn itself out early.
For the ones with dram led... Tech Yes Bryan found he could revive a "dead" 3600 by undervolting in the bios with a good cpu, and then switch to the dead one. It would be interesting if you could make any of yours work by undrvolting or reducing the clocks. [edit] lol, just got to the last one where you did just that. Worth re-checking some of the others similarly.
With the overheating CPUs, try delid and liquid metalling the CPU and putting the IHS back. The thermal glue inside might've dried out or not making contact with the IHS anymore
The 5900x seems similar to a few cases of degraded silicon I've seen. With some time you could probably dial in the voltage/clocks to get it running pretty close to stock. Not perfect but would still work well as a homelab CPU or something.
I have an old fx-8370 chip (use it as a test bench and backup media system now). Used to oc to 5.0GHz, but slowly became unstable over the years. Now it'll run fine forever at 4775MHz but not at 4800 or more.
As others said, the 5900X is "fixable" by disabling Global C-States control in BIOS, which disables core parking feature. My 5950x just did this last week, while it can be fixed by disabling this option, personally i decided to RMA it instead.

Hey Greg, thanks to you & your fix or flop series i was able to fix my 10 year old desktop, so let me share what happened the. Out of the blue the system started Blue screen of deaths different error everytime so i thought maybe the windows was corrupt and tried to fresh install the windows but it wouldn't let me boot via the Pendrive, so i thought maybe the HDD had given up the ghost. Had a spare HDD lying so decided to swap it and sometimes it would just bootloop and sometimes it would just give no output to display so started by disconnecting RAM's to narrow down the problem so guess what 1 of the RAM sticks had gone faulty so tried putting it in the other slot to rule out defective slot but the RAM was at fault so finally the system started with the other 4 gig stick. I didn't go to any repair shop as most of them just try to rip off, so thanks to you my potato pc started again.
I’m able to boot in b1 & b2 but anytime I try to use a1 or a2 I get error code 55 yellow light on ram everything lights on pc but no display on keyboard and mouse. Do you think this is a problem with the cpu or motherboard slits please let me know anything is helpful.
I have a Ryzen 72700X. Where one memory channel crapped out. What happened was I changed my cooler for one of those tower coolers and the weight on the tower cooler ripped the Ryzen out of its socket, and I am guessing that that caused some sort of electrical faultin the CPU, as it doesn't like being pulled out of its socket when the power is on. But that's what happened. The main fault lies with the top-heavy weight of the tower cooler and the CPU retention arm. The weight of the cooler pulled the arm out of its socket. There was an easy fix for this and that was to bend the arm towards the socket again, making a better contact with the catch. But by then it was too late. My verdict is --- Tower coolers are too top-heavy and the CPU retention arms are too weak and don't latch hard enough.
I am wondering if the silicon shortage over the last two years has contributed to this issue, are manufacturers reducing the failure threshold/overhead to pump out their products? I am in the process of building my new 13th gen system and it is a major concern that component quality might be compromised by the current lack of raw materials globally.
some AMD chips that have dual CCD(x900, x950, or some x600 series) may experience some impedance between CCDs especially when theres a degradation problem related to the silicon, their voltage needs heavy adjustment to work normally. TechYESCity demonstrated that by disabling cores/limiting boost frequencies some of these chips could be salvaged.
Great vid and quite helpful- I build a lot of Ryzen based computer systems and this helps with a "heads up" of possible outcomes. I have not yet witnessed these symptoms, but good to have this knowledge.
I just want to say thank you for the fix or flop content! Thanks to your methodology I was able to fix a friend's "dead" PC in less than 15 minutes. He thought the mobo was dead and asked me if I could look at it knowing that I have experience building PCs, and I was quickly able to narrow it down to just 1 dead RAM stick. I cleared the CMOS, swapped in a known working GPU, and then tested RAM one stick and one slot at a time. It was so satisfying being able to save that PC as it is still a relatively powerful system.. i7 9700k on a gigabyte z370 motherboard with an RX 6700xt.
I find it interesting the number of memory issues. Just replaced my 2700 X as the memory controller is depredating. It stopped being able to run the memory on XMP, so I had to drop the voltages and speeds down a few months ago(6) and it was stable until yesterday when the problem made a return. However, I believe a bad bios was to blame in my case as I found that the XMP had gone 1.45 V on Auto which was fixed with a bios update.
i changes some settings in bios i think cpu volatage ... then pc turn off himsef and wont boot again i try everything cmos reset ...what should i do its my new config 😔😔
Hi Greg Thanks for the always informative, and thorough videos. I wonder if you would share some Fix or flop statistics? Do you have as many faulty intel processors as ryzens? Put up against how many you got it in?
I also have a pc here that has AMD A10 apu in it. Everything was fine and stable in the bios(updated and set to defaults) but everytime i install an os, it keeps crashing and giving me bsod. I already tried changing the ssd, sata cable, and sata port but still same issues. When i install an os from a different pc(intel) then put back together to this pc it will boot up but after a few minutes it will crash and show bsod again.
@12:35 hahah this happened to my first Ryzen 9 5950x after trying out the dynamic oc feature on the Asus Dark Hero x570 it kept cycling between this and corrupted boot device.
A motherboard with debug codes instead of just LEDs (and a power button) would've probably been beneficial for these tests. Or regarding the power button, you could just use one from an unused case to connect it to the pins instead of having to short the jumpers all the time.
@@daveward4358 Greg did say he was trying to contact AMD about that but he just hasn't heard back from them yet. He did also say that he will update us once they do contact him back about it.
@@daveward4358 Not necessarily, only because we can neither confirm or deny if that's true without proof or evidence. What I can say for sure is that, there were a lot of people who bought these CPU's, so it's possible that failure rates can seem to be higher than what it truly is overall.
I have a ryzen cpu that would power on for about 10 seconds and then power off again then after about 3 seconds it powers on and just stay on without display/post/boot. My keyboard light and mouse doesn't appear.Also, my keyboard's Scroll Lock and Caps Lock are on and the keyboard won't respond with me clicking anything. What could possible cause this?
@GregSalazar I have a weird issue with a 5950X, where it boots into windows just fine, but when ever I try and install windows on a fresh drive, it locks up. Does it in Recovery, does it with USB media, does it with installing from the OS itself doing a system reset. Had 4 sticks of RAM, went down to 1 stick, and rotated between the 4 sticks individually in different slots, same issue. Memtest86 runs indefinitely without an issue though. I can even run a game and it wont crash, but I cannot reinstall windows! I am hoping its a motherboard issue of some kind, and have a new MB on the way to test it out, but I have never come across anything quite as bizzare. Changed PSU, and GPU too, no change to the behavour. Fresh HDD, cant even install off USB media as it locks up part way through selecting the options for the install. I had this in my main system, which was water cooled with a custom loop, and it ran for almost 2 years. No overclock, and the loop stayed really cool with a RTX3080 in the same loop. Dual radiators etc. Changed to an AM5 system now, but really want to get to the bottom of this, as it would be a good 2nd system or NAS kind of thing. Ever seen anything like this?
Greg, I envy your access to hardware, but I don't envy how much thermal paste you must go through in a week. I'd love to know what brand you use though.
I swapped my radiatior fans from intake to exhaust and got BSOD's. Reset Bios and it boots but if I overclock the RAM a little it BSOD's so I swapped the slots and it works fine now in A and C. Really confusing stuff.
Hey Greg, love your Videos. There is a possible workaround for those 3600's that are sticking on dram, Put in a working CPU, then goto BIOS and undervolt and downclock the ram speed. I have seen a LOT of 3600 and 3600x that after a couple of years developed a problem with ram speed
Where did you get that motherboard speaker from? I’ve tried those super tiny ones in the past, but they exude the shrillest, most unpleasant beep. This one was much better!
Hey Greg, found a intresting thing!! 16:30 / 16:37 time in the video when u press on the ram with your finger (Dram) light Changes to CPu , i dont know im the only one noticing it.. Love ur Content!!
I have a brand new ryzen 9 5900x and it was bootlooping exactly the same as yours straight out of the box is it safe to assume that the issue isn't to do with my pc or compatibility issues and instead just a faulty chip straight out of the box? Should I return it and try a new chip? I also have a ryzen 5 3600 and it runs perfectly fine with that and yes I did update my bios before installing the ryzen 9 5900x.
I was wondering.. with some of the ryzen 5 3600s with dead memory channels, could tighter timing ram in single channel perform as good as dual channel ram with looser timings ???
Hey Greg, Did you check thermals with the 5900x or not? Would have been easy to see if it's a thermal issue once in windows, because if it still goes up to the 90s in temperature with reduced settings like this, there must be Some kind of IHS contact issue internaly causing thermals to rise. Greetings!
for giggles I tried a older weed pen that stopped working (as they all do when the battery dies)....but today, I got two hits (with lights) and it still seems like it can give me more. I know it's not the same but I'm pretty stoked, literally :) Good vid Greg -- you're a genuine dude.
Great video man. I also like to revisit things to update that mental database where you think you had it figured it out, but in fact did not. Wonder if mem controller is getting torched or an issue with going to aggressive on the F-CLOCK damaging Infinity Fabric? I wouldn't know, I'm only a measly ZEN+ owner and haven't over clocked anything since boost clocks have been implemented in CPUs/GPUs. I'm from the old era. Overclocked my Athlon with a #2 pencil and then a car defogging repair kit. 🔥
good video, my only concern was when you put thbe second cpu on the board and had the same issue, I wondered if the previous cpu might have damaged the mother board. you should have off camera,put a known good cpu in and made sure the mother board and stuff was still good.
I just bought a brand new Ryzen 7 7800x3d and motherboard and ram to go with it but I can’t get it to post I’ve reseated the cpu and the ram but still nothing my motherboard has debug leds and the cpu one is red and the dram one is yellow but idk what that means any tips?

Maybe contact Steve from gamer nexus. This sort of situation might be down his alley. Especially if it shows to be a batch wide situation There could be hundreds of Ryzen 3000 chips on the verge of going bad and could open exactly why they could be turning. Might turn into an interesting collab.
I got a problem similar to this, I got a MSI B 550 A Pro motherboard with a Ryzen 5 5600. Worked great for a month, no heating issues. One day I go to power on the PC and it does nothing. Changed out the PSU and ram, gpu. still the same. Then I took out the CPU and it fired right up, but the motherboard will no longer let me bios flash. Keep in mind you do not need ram or cpu in most msi boards with bios button.
Hi. I just updated my cpu from a Ryzen 7 1700 to a ryzen 9 5900x. When I boot my pc it stuck on the motherboard name. Like frozen. I tried everything it still stuck. When I put my old cpu my system boot with no problems. Do you think the cpu is a bad cpu or it has to see with my motherboard. Before I did the swap I updated my bios too to the latest version. My motherboard is the MPG x570 gaming edge WiFi. I’m thinking it may be the CPU because I bought it used on Amazon
I had the same issue with a ryzen where it would post to bios and after resetting to default it wouldn't post. It ended up being a TPM setting. I used another CPU, installed Windows with the tpm bypass mod and it worked fine after
Hey Greg! I hope that you having a good day, I was wondering if there is a significant difference between a 360 mm aio with fans set to exhaust and a 280 mm aio with a push pull configuration.
Push/pull mostly doesn't make a huge difference for standard thickness AIO radiators as they're not thick enough for one set of fans to have trouble pushing air through. In this case, all other things being equal, the push-only 360 should have the higher heat capacity. However, as you get to thicker rads like the Arctic LFII or the sort commonly used in custom loops, push/pull becomes more relevant.
1st chip, had the identical issue with the exact same board with a 5600 the day after I assembled, i left it plugged out without the bios batterry and issue gone
I got a little problem. If i use the recommended DRAM slots and use XMP the pc won’t boot. But if I turn off xmp it will boot. If I use another set of DRAM in the same slots and with xmp the computer boots… But if I use another slots and use xmp, the computer boots… with the difference DRAMS.
I could be wrong but I'm pretty sure that the Bios Only uses 1 core meaning that there could be possibly a dead core that's getting Initialized after the splash screen that's causing the system to crash. Try disabling certain cores I believe that will actually solve the problem
For the 3600 cpus I would try a slower ram speed. I have a 3600X that will do nothing but give me issues if I use anything over 2400mhz ram. Its a definite issue and I only use the chip in a b550 board to test gpus and other components.
@@Smakheed Wow! I set up my friends workstation pc with a 3900xt and 32gb of 3200 and it just worked. And that was on a b450 AsRock board. I was using my 3600x on an asus x570 and figured 3200 would be fine but the cpu just doesnt like faster speeds. I'm sure with some tweaking i could get it stable but I don't have the time or desire to do so.
Would a broken CPU socket light up with the CPU debug light my i9 12900 K. Has 10 hours on it but i broke I broke one of the socket pins. It just wouldn't do anything. But CPU d bug light.
Not sure if it is a problem from AMD Agesa BIOS... I also experience a similar issue with my system (Ryzen 3600 and Aorus X570 Pro WiFi v1.0) and it happens, the Debug LED stays at DRAM, and then blink to CPU then DRAM again.
Just curious, is the dram controller on the cpu for channel A/B or channel 1/2? How does that work? Does the controller look at the numbers or letters? (A1A2, B1B2) hopefully that’s worded correctly
Yes, the memory controller is part of the I/0 die on the CPU...It controls both channels...I've seen alot of damaged memory controllers in Ryzen CPUs because people bump the SOC voltage too high while trying to overclock...
@Jeff Coutre Yea, just don't go past 1.35v...some people say you can go a little higher than that, but I have seen quite a few CPUs damaged by SOC voltage...It's best to play it a little safe
I know this video is kinda old, but i just got a Ryzen 9 5950x and my mobo gets stuck with a cpu light on; I've tested with just the mobo cpu and one Ram and it still just has cpu light on, any advice?
Hi Greg, I have a ryzen 5 3600 with aorus b450 elite. My pc wont start, and no light debug show in motherboard. Is the motherboard dead or my processor was dead? Help me, thank U
I've been in IT for over 30 years and I've personally only seen 1 failed processor. Two users with failed processors would have been crazy to me, but 5!? Intel isn't the best but this is shenanigans.
I have been watching your videos for a while. I got a pre built pc with ONE stick of 16GB ram. I have a question. I purchased 32GB of ram (Same brand. Same everything as the one in my PC). Is it ok to use 3 sticks of the same ram (48GB)? Or should I just use 2 sticks(32 GB)?
G'day Greg, This was really interesting, just a couple of thoughts for some more testing, Do you have another 5900X to get some BIOS 'Full Auto' Setting Stats running GB to compare Score, Temps, Core Voltage & so on, it would be interesting to see how this 5900X performs if you increase the Multiplier to see where it fails at 1.1v, also see if it boots with Volts - Auto at 3GHz & some other testing of this type, 🤔Maybe it could be a Live Sream ???
Make sure to disable some cores in the BIOS to see if chips will run afterwards. You can try manually increasing voltages or lowering clocks too. Sometimes some cores will die completely, other times just enabling PBO or even any boost frequency at all will be the issue. I've also seen it where it would basically need an extra 50mV to hold the advertised boost frequency. Mostly, these chips can be saved if you're willing to make compromises.
Greg, I don't know whether this interests you, but for bench testing a motherboard, I use a removable, external power switch. I like this better than physically shorting the power switch pins when I have to start up the same board many times. Of course, if you are working with a number of different boards at the same time, this would be more time consuming than shorting with a screwdriver.
I am curious what speeds the RAM was running at in the systems these CPUs with dead memory channels came from. Because, if I remember correctly, the RAM speed could affect the Infinity Fabric speed, and maybe there's a certain speed that, on certain chips, causes the Infinity Fabric to damage the Memory Lanes? Idk, I am just spouting off ideas that are popping into my head at 1 AM. Great work as always Greg!
maybe its incompatible memory with the cpu. being as the led for cpu goes off and goes to dram. m sure if it was a cpu problem the led would stay on cpu. so the cpu might be fine as its passing on diagnostic leds
i have a 5800x that i dropped while preparing to move it to another mobo, a few pins bent. would you be willing to take it off my hands to try to see if you can make it work? of course, you can keep it. i have no use since it's just a piece of metal to me now. i tried to fix the pins but i didnt have anything small enough to move them around
The ryzen 5 3600s with dead memory channels would be worth something to dell so they have an excuse to use single channel ram
BROOO 💀💀
damn
Yep, and Dawid just LOVES that single channel RAM
Fix or flop is getting intense!
Brian at Tech Yes City had similar issues with some Ryzen chips and found that some had bad cores and was able to get them working by disabling a core

Had a spare HDD lying so decided to swap it and sometimes it would just bootloop and sometimes it would just give no output to display so started by disconnecting RAM's to narrow down the problem so guess what 1 of the RAM sticks had gone faulty so tried putting it in the other slot to rule out defective slot but the RAM was at fault so finally the system started with the other 4 gig stick. I didn't go to any repair shop as most of them just try to rip off, so thanks to you my potato pc started again.
I’m able to boot in b1 & b2 but anytime I try to use a1 or a2 I get error code 55 yellow light on ram everything lights on pc but no display on keyboard and mouse. Do you think this is a problem with the cpu or motherboard slits please let me know anything is helpful.

Tech Yes City has had similar problems with AMD cpu's recently. Great video as always, Greg. Much respect.
I have a Ryzen 72700X. Where one memory channel crapped out. What happened was I changed my cooler for one of those tower coolers and the weight on the tower cooler ripped the Ryzen out of its socket, and I am guessing that that caused some sort of electrical faultin the CPU, as it doesn't like being pulled out of its socket when the power is on. But that's what happened. The main fault lies with the top-heavy weight of the tower cooler and the CPU retention arm. The weight of the cooler pulled the arm out of its socket. There was an easy fix for this and that was to bend the arm towards the socket again, making a better contact with the catch. But by then it was too late.
My verdict is --- Tower coolers are too top-heavy and the CPU retention arms are too weak and don't latch hard enough.
I am wondering if the silicon shortage over the last two years has contributed to this issue, are manufacturers reducing the failure threshold/overhead to pump out their products? I am in the process of building my new 13th gen system and it is a major concern that component quality might be compromised by the current lack of raw materials globally.
This video's great! the monologue of troubleshooting shows how people may want to try to do when they encounter problems with their systems.
some AMD chips that have dual CCD(x900, x950, or some x600 series) may experience some impedance between CCDs especially when theres a degradation problem related to the silicon, their voltage needs heavy adjustment to work normally. TechYESCity demonstrated that by disabling cores/limiting boost frequencies some of these chips could be salvaged.
Great vid and quite helpful- I build a lot of Ryzen based computer systems and this helps with a "heads up" of possible outcomes. I have not yet witnessed these symptoms, but good to have this knowledge.
I just want to say thank you for the fix or flop content! Thanks to your methodology I was able to fix a friend's "dead" PC in less than 15 minutes. He thought the mobo was dead and asked me if I could look at it knowing that I have experience building PCs, and I was quickly able to narrow it down to just 1 dead RAM stick. I cleared the CMOS, swapped in a known working GPU, and then tested RAM one stick and one slot at a time. It was so satisfying being able to save that PC as it is still a relatively powerful system.. i7 9700k on a gigabyte z370 motherboard with an RX 6700xt.
I find it interesting the number of memory issues. Just replaced my 2700 X as the memory controller is depredating. It stopped being able to run the memory on XMP, so I had to drop the voltages and speeds down a few months ago(6) and it was stable until yesterday when the problem made a return. However, I believe a bad bios was to blame in my case as I found that the XMP had gone 1.45 V on Auto which was fixed with a bios update.
i changes some settings in bios i think cpu volatage ... then pc turn off himsef and wont boot again i try everything cmos reset ...what should i do its my new config 😔😔
Hi Greg
Thanks for the always informative, and thorough videos.
I wonder if you would share some Fix or flop statistics?
Do you have as many faulty intel processors as ryzens? Put up against how many you got it in?
Ryzen cpu are very peculiar with memory. Is it possible to try different AMD recommended memory modules?
Memory was isolated in their respective FoF episodes on top of the single DIMM used here at 2133 MHz.
"Died" Zen CPU - this is normal for Gigabyte mobo. There are many cases even on TH-cam. There will always be a Aorus mother .
I also have a pc here that has AMD A10 apu in it. Everything was fine and stable in the bios(updated and set to defaults) but everytime i install an os, it keeps crashing and giving me bsod. I already tried changing the ssd, sata cable, and sata port but still same issues. When i install an os from a different pc(intel) then put back together to this pc it will boot up but after a few minutes it will crash and show bsod again.
@12:35 hahah this happened to my first Ryzen 9 5950x after trying out the dynamic oc feature on the Asus Dark Hero x570 it kept cycling between this and corrupted boot device.
But can any of these get replaced under warranty?
A motherboard with debug codes instead of just LEDs (and a power button) would've probably been beneficial for these tests.
Or regarding the power button, you could just use one from an unused case to connect it to the pins instead of having to short the jumpers all the time.
Same here.
I thought they were going to be sent back to AMD to test them?
@@daveward4358 Greg did say he was trying to contact AMD about that but he just hasn't heard back from them yet. He did also say that he will update us once they do contact him back about it.
@@JCmeister9 So AMD probably know they sent out bad batches.
@@daveward4358 Not necessarily, only because we can neither confirm or deny if that's true without proof or evidence. What I can say for sure is that, there were a lot of people who bought these CPU's, so it's possible that failure rates can seem to be higher than what it truly is overall.
I have a ryzen cpu that would power on for about 10 seconds and then power off again then after about 3 seconds it powers on and just stay on without display/post/boot. My keyboard light and mouse doesn't appear.Also, my keyboard's Scroll Lock and Caps Lock are on and the keyboard won't respond with me clicking anything. What could possible cause this?
im about to get a 7800x3d and first amd cpu for me since athlon, should i be worried about the quality of these amd chips?
@GregSalazar I have a weird issue with a 5950X, where it boots into windows just fine, but when ever I try and install windows on a fresh drive, it locks up. Does it in Recovery, does it with USB media, does it with installing from the OS itself doing a system reset. Had 4 sticks of RAM, went down to 1 stick, and rotated between the 4 sticks individually in different slots, same issue. Memtest86 runs indefinitely without an issue though. I can even run a game and it wont crash, but I cannot reinstall windows! I am hoping its a motherboard issue of some kind, and have a new MB on the way to test it out, but I have never come across anything quite as bizzare. Changed PSU, and GPU too, no change to the behavour. Fresh HDD, cant even install off USB media as it locks up part way through selecting the options for the install.
I had this in my main system, which was water cooled with a custom loop, and it ran for almost 2 years. No overclock, and the loop stayed really cool with a RTX3080 in the same loop. Dual radiators etc.
Changed to an AM5 system now, but really want to get to the bottom of this, as it would be a good 2nd system or NAS kind of thing.
Ever seen anything like this?
Greg, I envy your access to hardware, but I don't envy how much thermal paste you must go through in a week. I'd love to know what brand you use though.
I swapped my radiatior fans from intake to exhaust and got BSOD's. Reset Bios and it boots but if I overclock the RAM a little it BSOD's so I swapped the slots and it works fine now in A and C. Really confusing stuff.
Thanks for the follow up. I would like to see if any of the mobos are salvageable.
Hey Greg, love your Videos. There is a possible workaround for those 3600's that are sticking on dram, Put in a working CPU, then goto BIOS and undervolt and downclock the ram speed. I have seen a LOT of 3600 and 3600x that after a couple of years developed a problem with ram speed
Greg did you notice the spark at 6:28 would that be the cause of the issue?
Oh shit! Good catch
Where did you get that motherboard speaker from? I’ve tried those super tiny ones in the past, but they exude the shrillest, most unpleasant beep. This one was much better!
Hey Greg, found a intresting thing!! 16:30 / 16:37 time in the video when u press on the ram with your finger (Dram) light Changes to CPu , i dont know im the only one noticing it.. Love ur Content!!
I had a 3600X keep resetting when I tried to play videos. I contacted AMD, they couldn't figure the issue. After 2 weeks, they sent me a replacement.
I have a brand new ryzen 9 5900x and it was bootlooping exactly the same as yours straight out of the box is it safe to assume that the issue isn't to do with my pc or compatibility issues and instead just a faulty chip straight out of the box? Should I return it and try a new chip? I also have a ryzen 5 3600 and it runs perfectly fine with that and yes I did update my bios before installing the ryzen 9 5900x.
@12:40 , Should set the RAM speed lower , I have same issues with mine , never OC'd and was always set in eco mode with 45w limits etc
i would reset the cmos every time when swapping the cpu. maybe it does not wanna work with various speeds or timings. just to be sure.
I was wondering.. with some of the ryzen 5 3600s with dead memory channels, could tighter timing ram in single channel perform as good as dual channel ram with looser timings ???
Hey Greg,
Did you check thermals with the 5900x or not? Would have been easy to see if it's a thermal issue once in windows, because if it still goes up to the 90s in temperature with reduced settings like this, there must be Some kind of IHS contact issue internaly causing thermals to rise.
Greetings!
Love you vids again Greg, anyways that Blue Eyes Toon Dragon was cool at your back
Good vid, love the troubleshooting.
for giggles I tried a older weed pen that stopped working (as they all do when the battery dies)....but today, I got two hits (with lights) and it still seems like it can give me more. I know it's not the same but I'm pretty stoked, literally :) Good vid Greg -- you're a genuine dude.
Did you clear the CMOS for every CPU?
Great video man. I also like to revisit things to update that mental database where you think you had it figured it out, but in fact did not. Wonder if mem controller is getting torched or an issue with going to aggressive on the F-CLOCK damaging Infinity Fabric? I wouldn't know, I'm only a measly ZEN+ owner and haven't over clocked anything since boost clocks have been implemented in CPUs/GPUs. I'm from the old era. Overclocked my Athlon with a #2 pencil and then a car defogging repair kit. 🔥
Greg your channel is sooo good! I am really enjoying it. Please keep it up. 👏🏼
good video, my only concern was when you put thbe second cpu on the board and had the same issue, I wondered if the previous cpu might have damaged the mother board. you should have off camera,put a known good cpu in and made sure the mother board and stuff was still good.
? The exact same board was used for all tests and worked perfectly fine for other chips AFTER the first damaged one was tested.
I just bought a brand new Ryzen 7 7800x3d and motherboard and ram to go with it but I can’t get it to post I’ve reseated the cpu and the ram but still nothing my motherboard has debug leds and the cpu one is red and the dram one is yellow but idk what that means any tips?
im from malaysia, i had a problem with my pc, i bought everything new except gpu, i had a problem with my pc, sometime it wont boot the display like 75 percent wont 25 percent it boot fine(could be die in the middle on, giving 5 beepiing when trying to boot up, i tried change everything, put one by one on healthy pc, still not finding any, this is some kind of mysterious sick, help
Maybe contact Steve from gamer nexus. This sort of situation might be down his alley. Especially if it shows to be a batch wide situation There could be hundreds of Ryzen 3000 chips on the verge of going bad and could open exactly why they could be turning. Might turn into an interesting collab.
I got a problem similar to this, I got a MSI B 550 A Pro motherboard with a Ryzen 5 5600. Worked great for a month, no heating issues. One day I go to power on the PC and it does nothing. Changed out the PSU and ram, gpu. still the same. Then I took out the CPU and it fired right up, but the motherboard will no longer let me bios flash. Keep in mind you do not need ram or cpu in most msi boards with bios button.
Hi. I just updated my cpu from a Ryzen 7 1700 to a ryzen 9 5900x. When I boot my pc it stuck on the motherboard name. Like frozen. I tried everything it still stuck. When I put my old cpu my system boot with no problems. Do you think the cpu is a bad cpu or it has to see with my motherboard. Before I did the swap I updated my bios too to the latest version. My motherboard is the MPG x570 gaming edge WiFi. I’m thinking it may be the CPU because I bought it used on Amazon
I had the same issue with a ryzen where it would post to bios and after resetting to default it wouldn't post. It ended up being a TPM setting. I used another CPU, installed Windows with the tpm bypass mod and it worked fine after
Hey Greg! I hope that you having a good day, I was wondering if there is a significant difference between a 360 mm aio with fans set to exhaust and a 280 mm aio with a push pull configuration.
Push/pull mostly doesn't make a huge difference for standard thickness AIO radiators as they're not thick enough for one set of fans to have trouble pushing air through. In this case, all other things being equal, the push-only 360 should have the higher heat capacity. However, as you get to thicker rads like the Arctic LFII or the sort commonly used in custom loops, push/pull becomes more relevant.
1st chip, had the identical issue with the exact same board with a 5600 the day after I assembled, i left it plugged out without the bios batterry and issue gone
I got a little problem. If i use the recommended DRAM slots and use XMP the pc won’t boot. But if I turn off xmp it will boot.
If I use another set of DRAM in the same slots and with xmp the computer boots…
But if I use another slots and use xmp, the computer boots… with the difference DRAMS.
I could be wrong but I'm pretty sure that the Bios Only uses 1 core meaning that there could be possibly a dead core that's getting Initialized after the splash screen that's causing the system to crash. Try disabling certain cores I believe that will actually solve the problem
TechYesCity also had this overheating issue with ryzen 3600s. You can also try disabling cpu cores if undervolting doesn't work and see if it works.
8:06 di something short underneath the motherboard?
On the CPU around 1230 did you attempt to stop c-states? It might be undervolting not overvolting?
Would it help if you had a board that displayed numbers and not just lights?
For the 3600 cpus I would try a slower ram speed. I have a 3600X that will do nothing but give me issues if I use anything over 2400mhz ram. Its a definite issue and I only use the chip in a b550 board to test gpus and other components.
I've seen 3950 chips do that too, anything over 3000Mhz RAM and they wont post.
@@Smakheed Wow! I set up my friends workstation pc with a 3900xt and 32gb of 3200 and it just worked. And that was on a b450 AsRock board. I was using my 3600x on an asus x570 and figured 3200 would be fine but the cpu just doesnt like faster speeds. I'm sure with some tweaking i could get it stable but I don't have the time or desire to do so.
Would a broken CPU socket light up with the CPU debug light my i9 12900 K. Has 10 hours on it but i broke I broke one of the socket pins. It just wouldn't do anything. But CPU d bug light.
I wonder if slower memory (2400 or less) can work with the first couple of chips with dram errors.
His ram was running at 2133mhz
Is there a reason for the Ram channels going bad? Is it more likely to happen due to overclocking or something like that?
Not sure if it is a problem from AMD Agesa BIOS... I also experience a similar issue with my system (Ryzen 3600 and Aorus X570 Pro WiFi v1.0) and it happens, the Debug LED stays at DRAM, and then blink to CPU then DRAM again.
Just curious, is the dram controller on the cpu for channel A/B or channel 1/2? How does that work? Does the controller look at the numbers or letters? (A1A2, B1B2) hopefully that’s worded correctly
Nvm. I was only 1/4 way through the video when I asked lol you answered it over halfway through
Yes, the memory controller is part of the I/0 die on the CPU...It controls both channels...I've seen alot of damaged memory controllers in Ryzen CPUs because people bump the SOC voltage too high while trying to overclock...
@@brucepreston3927 I have my soc v set for 1.2v is that safe?
@Jeff Coutre Yea, just don't go past 1.35v...some people say you can go a little higher than that, but I have seen quite a few CPUs damaged by SOC voltage...It's best to play it a little safe
I know this video is kinda old, but i just got a Ryzen 9 5950x and my mobo gets stuck with a cpu light on; I've tested with just the mobo cpu and one Ram and it still just has cpu light on, any advice?
Hi Greg, I have a ryzen 5 3600 with aorus b450 elite. My pc wont start, and no light debug show in motherboard. Is the motherboard dead or my processor was dead? Help me, thank U
Why dont you get one of them cases where you put the platform on he has its own psu i cant remember the case is it a test bench
I've been in IT for over 30 years and I've personally only seen 1 failed processor. Two users with failed processors would have been crazy to me, but 5!? Intel isn't the best but this is shenanigans.
Hey so I have a question about dram channels on cpus. Is there anyway you can fix the cpu like take it apart at all or no
anyone care to explain whats that light at 6:27 when greg turn his psu on
My 5600g did the same and I wonder if it was the voltage thing it was Overclocked manually for 2 years
I have been watching your videos for a while. I got a pre built pc with ONE stick of 16GB ram. I have a question. I purchased 32GB of ram (Same brand. Same everything as the one in my PC). Is it ok to use 3 sticks of the same ram (48GB)? Or should I just use 2 sticks(32 GB)?
G'day Greg,
This was really interesting, just a couple of thoughts for some more testing,
Do you have another 5900X to get some BIOS 'Full Auto' Setting Stats running GB to compare Score, Temps, Core Voltage & so on, it would be interesting to see how this 5900X performs if you increase the Multiplier to see where it fails at 1.1v, also see if it boots with Volts - Auto at 3GHz & some other testing of this type, 🤔Maybe it could be a Live Sream ???
did anyone see the spark on the bottom of the motherboard at 5:18?
At 19:50 the keyboard is not connected wirelessly, maybe something would happen with a wired one, no idea though
Make sure to disable some cores in the BIOS to see if chips will run afterwards. You can try manually increasing voltages or lowering clocks too. Sometimes some cores will die completely, other times just enabling PBO or even any boost frequency at all will be the issue. I've also seen it where it would basically need an extra 50mV to hold the advertised boost frequency. Mostly, these chips can be saved if you're willing to make compromises.
Greg, I don't know whether this interests you, but for bench testing a motherboard, I use a removable, external power switch. I like this better than physically shorting the power switch pins when I have to start up the same board many times. Of course, if you are working with a number of different boards at the same time, this would be more time consuming than shorting with a screwdriver.
i have a similiar issue with my laptop, ryzen 7 4800h, sometimes just black screens and restarts
the bootup beep sounds seem to be controlled by the mother board I have to set it to on in my MSI bios
I have a Ryzen 9 5900x as well that just boot loops when trying to go into WIndows. I just got tired of it and replaced it.
I am curious what speeds the RAM was running at in the systems these CPUs with dead memory channels came from. Because, if I remember correctly, the RAM speed could affect the Infinity Fabric speed, and maybe there's a certain speed that, on certain chips, causes the Infinity Fabric to damage the Memory Lanes?
Idk, I am just spouting off ideas that are popping into my head at 1 AM. Great work as always Greg!
maybe its incompatible memory with the cpu. being as the led for cpu goes off and goes to dram. m sure if it was a cpu problem the led would stay on cpu. so the cpu might be fine as its passing on diagnostic leds
I wonder if you could reflow the solder on the 5950x to help with the heat issue if that is in fact what it was.
i have a 5800x that i dropped while preparing to move it to another mobo, a few pins bent. would you be willing to take it off my hands to try to see if you can make it work? of course, you can keep it. i have no use since it's just a piece of metal to me now. i tried to fix the pins but i didnt have anything small enough to move them around
Use a mechanical pencil with no lead in it. It will fit over the pins. A sowing needle will also work well.
