#Undervolt #Overclock #Ryzen - แนวปฏิบัติและการใช้ชีวิต
Surprised not one person mentioned that we remove the latency penalty incurred by circumventing dynamic boost.... Enjoy!
I did notice that you were pushing the BIOS flashback on the back of the motherboard which is not the clear CMOS.
Because everyone has been bitching about it, before you proceed to GPU undervolt tutorial, please do a comparison benchmark of Curve Optimizer undervolting vs hard capping clock/voltage undervolting.
Better latency without turbo boost?
@@richardfarmer6570 Yeah I saw that too. This is my first time on this channel, and that in particular got me worried.
@@araisikewai yeah I think that's the best way too. Will make that happen.
Ryzen chips, especially the lower core chips are exceptionally good at undervolting. I left my 5600x at normal clock speeds whilst just lowering voltage. By doing so I managed to get my 5600X to run a R23 run at 4.6GHz with a -300mV undervolt. So whilst under stress it runs normal clock speeds at 990-1.06V. That’s a golden sample.
Do you recall if consumption changed? In my case I can only undervolt by 0.1125 (rock sample?), and it does run R23 at 4.35 instead of 4.0, but the R23 score is very comparable.
The only way I can reduce consumption seems to be with fixed speed (e.g. 4000 MHz).
@@danimagfernandesYou can either set a max power draw or use a negative offset for the frequency as well in pbo. I personally did the latter with a very conservative -100mv and it is doing great so far. Max clock speed went down a bit, but the main thing is that the power draw went from 70 to 58 or so and it can still downclock for better idle consumption
How much drop in temp?
Thank you for this! I did not see on any of these videos if I could keep the speed at stock ratio. Thanks to your comment I know I can.
I just did that and did a open benchmark test is says performing below expectations
I was literally thinking of looking up an undervolt guide this evening! More for the heat output than the electric bill, but saving money is always good. 😁 Looking forward to the graphics card guides as well, for sure!
Been using Bryan's OC tutorial for years. Really helped me setup my XEON E5-1680v2 on an ASUS P9X79 Pro. Temps-voltages...all good and stable (while air cooled) over the last 3 years.
Great tutorial video. Laid everything out nice and simple! Honestly, so few resources that are short sweet and to the point these days. And many written articles are either outdated or a bit wrong (usually just on user forums).
My GPU is undervolted and now, after watching this, my CPU will be too. Next adventure is the RAM timings which I want to bring down a little if I'm able...
Great tutorial, undervoltong is really handy in sff cases aswell, when you can't fit a large cooler. Although alot of sff now supports aios. Would love some insight from you on the curve optimizer feature on amd cpus aswell.
Great video! Can you use this menthod and use Curve Optimizer as well or is it just one or the other?
thanks for the video ! cant wait for the rest !!! so excited !
Great results, looking forward to the Alder Lake testing.
Video is unfortunately many months old, but still just want to thank you for this excellent guide. My newest 7700-build is great, but was running a bit hot and frequently pushing the fan-noise a bit more than I wanted. Now the temperatures have gone down a lot, so the fans are extremely quiet in game as well, and against all logic, gaming experience and all tested benchmarks are still as good as before. Double upvote.
I might have to give this a go, also looking forward to an in depth 3000 series undervolt guide!! I just got a brand new 3080 ti from NVidia after my first one died. I did follow an undervolt guide but it didn't go into the details, it was just set this curve and drag it down a bit.
Good that i found your video, it was dificult for me to undertsant because the other videos were with another bios, but with you i did understand it and it improved my temperatures amazingly
Enjoyed watching this. Is there anyway to apply the offset to overclocking or PBO. I have had bettter experiences with manually tweaking that PBO.
That is indeed very helpfull video , thank . Cant wait to try it on my CPU . Just one question . Is it necessary to lower the CPU frequency to try this method ?
Thanks for this video Brian. I have a 5500 I've yet to install so I'll follow this in the future.
Hey Brian thanks for the video! I use Asus X470 Gaming - F/3700X with .07500 MV for a perfect balance of performance and efficiency. I haven't taken it down further but it does go more. Temps in Cinebench R23 stay around 71C after 10 minutes of running. (noctua 12A with two fans) Maybe I should take it further? hmmm.
Hi Bryan, i don't have as many settings in my budget bios as in your video. However, I did set a static 1.025v @ 4ghz in my bios and now get ~15c lower temps in games. Combined with an undervolt on my rx 6700xt, I've dramatically lowered system power consumption. Thanks tons for your fantastic tutorial videos.
Thanks for the effort! 😀
It seems like this (video's) undervolt approach is different from via PBO? Do they conflict? Do you need to disable anything from PBO? Mine PBO configs are all in default "Auto".
Great video and guide. Thorough and very easy to follow. I’ve got a question though. I just bought a 5800X (cooled by my trusty old Noctua NH-D15) that i’ve paired with my MSI B550-A Pro motherboard. If i don’t want to downclock the ”CPU Core Ratio” is there something else i should do or can i just skip that step in the Bios and still follow this guide, maybe don’t lower the ”VDDR CPU Offset Voltage” as much? Thanks in advance/ Isak
YOU SAVED MY LIFE. THANK YOU. Brand new Custom build was running over 95C in games and with undervolting .12500 MV is a perfect sweet spot for me. Hovering around 70C while gaming now. Thank you so much.
I'm switching from PBO to your method after watching this. Locked my 7600x to 5.2ghz all core at 1.2v (from 1.25) with a 100mv offset as well. Seems stable. Cinebench is just about as fast as with PBO boosting to 5.45ghz, but my power draw went from around 100w to 75w and temps are cooler. Should be snappier overall locked at 5.2 versus boosting between 4-5.4 GHz... Idle power draw maybe went up a few watts, but nothing crazy.
I'm pretty happy with 75w and high 50's temps at 5.2ghz.
@Tech YES City can you use the Ryzen Master app to change freq and volt as I have seen in some other vids but it seem they didn't get crazy drops in temp. Or is better to do all the adjusting in bios?
Great guide!
A few stats for my 5800x in case anyone else is interested. All figures taken from cpuid (NOT the bios, on my msi board, a -0.025v offset resulted in a 0.23v delta!). dynamic boost had it going up to 4.7Ghz at stock, I locked it down to 4.4Ghz, any higher required significantly more voltage.
Stock - 1.3v - 145W package - 85c with my custom loop ramping up to full speed - 15200 points in cinebench
After - 1.07v - 97W package - 66c with my loop keeping all fans and pumps at minimum - 14900 points
I saw my board offered a 95W eco mode under the PBO settings, so thought I'd see if that did any better...
PBO 95W - 1.2v - 122W package - 78c with fans ramping up somewhat - 14900 points
It did MUCH worse!
Thankyou for keeping my PC super silent, even when gaming, I'm going to give your Nvidia underclocking guide a run through later to see if I can save some more power from my 3080ti.
Thanks for this info!
So your core voltage is 1.07 and your cpu ratio is 44x right ? Interesting, I will try it on my rig to see how it turns out
My Mainboard can PBO2, so I take a negative -30 on all cores. Then on all cores -125Mhz (because it boostet to 4.846Ghz on default) so thats on stable 4.716Ghz. PBO Limits disabled.
My temps are now 73°C max in Cinebench, from 83-84°C, with NO performance loss. I have the same performance (sometimes a little bit higher then default)
In gaming it was before 70-76°C and now ~55°C and 61°C max xDDD Thats so crazy.. Cooling is a 280mm (2x 140mm Fans) Radiator in the top. in front i have 3x 120mm and at the back 1x 120mm for good Airflow. Mainboard is a Gigabyte Aorus Elite V2. Easy Undervolt and 10-15°C better temps xD
Hey yes man, Nice video btw, I have a Ryzen 7 1700 on my X370 board and im looking to upgrade, do you think that Ryzen 5 5500 is a good cpu, I'm not concerned about pcie 4.0 (i know 5500 lacks it but still my board can't support it so it's whatever) I'm doing some gaming/video editing, and I'm looking for an all around good cpu (my 1700 has low ipc), respond asap, love your videos
great content as always 👏
Relatively small decreases in voltage can improve temperatures greatly. If you totally lost the silicon lottery even 40mv can help more towards cooling than switching to thermal grizzly kryonaut as a thermal interface.
thanks, a side i had not seen for ryzen! pardon the ignorance but, how does this go along with curve optimizer thing?
Thanks Bryan! This is so helpful!
Ryzen Master has the curve optimizer tool to do UV(=less power and temps) without losing performance. In order to consume less power, it is even easier to just power limit the CPU in the BIOS down to 45W (minimum) and keep the high single core boost. For Intel or old AMD CPUs though, this type of UV you showed in the video is the best one.
Unfortunately RM doesn't work on laptops:/
@@IM_MOUNTAIN Agreed! I lowered the figures Ryzen Master CO test per core suggested by 2 for the higher ones, iow the -30 to -28, -29 to -27 and system is stable.
@@giorx5 What CPU do you have, as I found, earlier today, that Ryzen Master does not support the Ryzen 5500.
@@bigj1454 I have a Ryzen 5 5600.
@@giorx5 After watching this video (because I have an unstable system at high load) and reading the comments, I tried the BIOS fix, but have a GIGABYTE Aurus Elite x570 motherboard and all the settings are in different places and maybe not labelled the same as in the Asus, so I scrapped that idea and just moved the Curve Optimiser to -5. Mainly because the CPU not supported in Ryzen Master as well. So far I passed all the stress tests in OCTT, and 4 hours in a game that crashed after 2 or 3. Crazy - I was thinking maybe the PSU was getting spikes in power draw and was/am thinking of swapping for a £200 upgerade with 1200W (nerly twice the recommended). but maybe it's all because of AMD/Gigasbyte settings that are too close to the edge of stability? Time will tell.
Amazing video, nicely detailed! Even a novice like me got through it with better temps & power consumption.
Added bonus exact same bios. Running almost 10c cooler on aio & stable
I had a PBO 2 curve optimization undervolt, which worked a bit hot but fine for a long time, because of many different reasons I recently encountered more heat problems which made it pretty unstable.
Now I just turned off PBO 2 and did some undervolting as in the video ("dynamic vcore" in gigabyte BIOS).
Quite a significant drop in Cinebench r23 (15000 to 14000) but in the few games I tested so far the performance drop is basically not noticeable and with way better temps.
Works great. Thanks.
Witch cpu did you use?
@@JaggersMusic R7 5800X
Excellent this is going to come in handy for me
Thanks a lot. I've been trying multiple ways to undervolt my Ryzen 5900x and only yours gave me a successful result : - 15 degrees, - 40 watt (0.1 offset was the limit for me but it's quite efficient).
Cheers from France !
Omg,Bryan that's the reason I've been followin' you all the time.This kind of videos.Regards from Serbia!
I had no access to PBO setting in bios so my option was to use pbotuner which doesnt retain settings between reboot. I only ever had to undervolt gpus so i was so lost. You really demystified the process. Thank you. My cpu is cool and happy in my shoe box sized PC case.
How does this compare to pbo on your test cpu? Great video
We need more "how to" videos like this straight from your desktop ! 👍
After watching this tutorial, I somehow managed to get my Ryzen 7 5700X to a voltage of 1 Volt (it occasionally dips beneath a Volt), with a temperature of 35-52 degrees, depending on load, with an average wattage of just under 30 Watts!
Thank you so much, now I can actually use my computer in the summer and not have 33 degrees ambient temperature in my room at night!
I have the same CPU. it does not let me drop to .15 as well xd but damn! a lot of decrease from 78 to only 55W!
Can you share the parameters of your config please?. I need to compare something. Thanks...
What's the point of posting only power and thermal number without performance stats. You can unplug the PC and it draws 0 Watt.
What voltage and frenquency plz ?
@@mr.mok7I have my ryzen 5700x running 42.75@1.050v
Thank you for this video. I've been lucky enough to lower my 5900x voltage from 1.500 by a .20 offset. Seems very stable so far. Idle temp is about 43C. Thanks again!
Great content, I need to undervolt my 5800xt to get it into an iTx build/case. But no mention of PBO undervolt or status. I was looking at a PBO UV of PPT 115W, TDC 90A, EDC 105 A? 🌈
Good guide. Well done as always.
Thank u, this was incredibely helpful.
Great video of the golden cost do you have any measure numbers for the 7 5800x if so can you tell us
Pretty good guide and it's not too far off of how i do it. I still usually leave the multiplier to Auto and as others have said, pretty much just maxing out the negative curve optimizer will boost the multi-core score. I also go for the max PBO core boost clock (+200) on these lower end Ryzens. I just rebuilt my sons computer using the 5600 and it's rock-solid and only consuming around 70W at max boost. My only other recommendation is to also undervolt the SOC. You don't get as much benefit as you do optimizing the vcore but if you're in for a penny, might as well be in for the pound.
I'd also like to see you take a stab at a DRAM tuning guide. I am currently running through tuning my 5800X3D and the uplift in graphics performance is pronounced (350 point delta in Timespy). My aggressive 3200 Mhz tuning (CL13+very low sub-timings) is currently outperforming the 4000Mhz profile I had setup previously (CL17+ not quite as tightly tuned sub-timings) and the lower RAM speed has the benefit of requiring you to pump less voltage into the SOC. It might be too much for a video since there are SOO many sub-timings to modify but you can streamline the tuning by just using so simple shortcuts (like only dropping by 1 on single digit timings, 2 on timings in the 10-20 range and so on).
i can't wait to see part 2 whit undervolt of the rx 6700 xt ;) 200 watts to beat was my sweet spot for keeping it performing to my taste radeon chill do marvel by it self though for easier stuff to run.
Did got similar result in past whit r5 5600g granted was not using igpu portion was impressive too at 4.4 was keeping power under 45 watts too in my game probably would peak higher in that r23 though.
Nice content super relevante keep the good work was wondering what kind of cooling where you using my bet is wraith max cooler :P
Hey mate, would this work with a Ryzen 3900x and GTX 1070 ti? After leaving Vietnam last year, finally getting around to getting my systems together. I'm using a classic Mac Pro for video editing and streaming, so this would help out with my gaming system I'm throwing together from used parts.
Would have been nice to see before and after results for games rather than synthetic benchmarks, sure you didn’t crash during Apex but how much real world performance did you lose in Apex? Synthetic benchmarks don’t really mean much as far as gaming is concerned. I took 80w and 10 degrees Celsius out of my 3070(gpu) and only lost 5fps. My fans run slower as well. Definitely noticed how much less heat in in the room. As for my 5600x(cpu) it’s water cooled so I run it with PBO enabled +200mhz and let it do its thing. Playing Warzone so I need all the processing power I can get.
@techyescity you mentioned you would put starting points for Ryzen 9 do you happen to have those.
Maaan i tell you what. When i saw a 30min. video of yours (i already know how to undervolt ryzen) i was 'noooo, there's no way i'm gonna watch it, it's sooo long'. And it's a damn true man. All your videos, which involve easy steps, TAKE SO FREAKING LONG!
thank you so much this was so helpful for me.
On Ryzen you can change PPT to get lower total power draw, even though it's not technically undervolting it can help with temperatures in a similar way. You can also change the number of active cores (I forget what the setting is called) but it doesn't really improve power draw unless you're running less than half of the cores active.
I used PBO with around 100mv offset, and manually limited power. CPU runs 100MHz faster all core, with ~20% less power. A note on cheap power supplies. They are likely to have higher voltage ripple, which makes undervolts more unstable. I also tend to get instability at idle, or after stopping a test so it is important to test all scenarios, and bump up voltage slightly if you have intermittent crashes.
Crashes probably because you didn’t reset cmo’s after messing with your memory timings. This is why you don’t watch dorks on TH-cam with failed IT careers talk you into electrical engineering. AMD fabric clocks by default are meant for sustainability. You can have a 5.0ghz oc but use 5 watts on idle. You are actually down tiering performance under volts, vs playing with voltage delivery. You are probably also using more power To render lighter work loads.
I have a 5800X undervolt -0.15 and power curve optimizer -15 =13136 multicore score. Down from 15113 max score but Temps maxed out at 65 with 30 min stability test. Temps was around 80 before.
Thank you very much! I'm running a 5950x on a NH-15.

what u write at the bios settings? please help
Amazing video Brian 👍 can you do a video for the 5800 X cpu
Been rocking a 5800x for about 8 months, and when I first got put it in I was hitting 90C stock in CB20 on an NH-D15S. Figured out it was the setting's the mobo was applying (B450 Tomahawk Max). I messed around with PBO, and max was 85C-86C. Upgraded to an X570 Unify, and stock found its Mobo settings to be almost exactly what my PBO settings were on the B450, and again hitting 86C max. Leaving everything stock, except RAM profile, I added a negative voltage offset of .1V, and allowed the CPU to boost to whatever with that voltage offset. I did try lower voltages, but I started to get clock stretching, and my performance dropped considerably. With the .1V (-) offset temps are down to 72C max, using 20 less watts, and actually didn't lose any performance in CB20. Still boost to 4.8Ghz single core as well, but is much quieter doing so. lol Before while gaming, the 5800x was running louder and hotter on the NH-D15 than the 3080 12GB I got a couple of weeks ago. I checked paste and reseated the cooler a couple of times now, and came to the conclusion this thing just runs kinda warm. With the undervolt, on both the CPU and GPU, I hope it helps to keep my room a little cooler through this west Texas summer, but in the winter I do have my "heater" settings. lol
Aright, been experimenting a little more, and got my settings about locked it. I locked my 5800X to 4.6Ghz @ 1.29375V (Any lower and it was unstable) Scored 80 points less than my best score in CB20, while using 40W less power, and maxing at 67C from 86-87C. I think I'll take that trade off! Thanks for the video to help provide a little more understanding about how to extract the most out of these chips.
Hi ,thanks for your vid, that's help me to understand and try the same. the 5800X 3D i test agree to have only 0.90v @ 4.4Ghz CB15 is 2120 score , it's low ? with OCCT the temp is under 50°C (NH-D15) and less than 70w consumption :)
My 10900k was around 1.3-1.4 load voltage out of the box. I set static voltage to 1.34 @ 5.1GHZ all core (before vdroop - so 1.288v on load), 4.9ghz cache. Dropped from 90 to 60 degrees average in games and had a much better all core frequency. Though i lost 200mhz single thread which doesnt really matter to me.
hey! thanks for the video but im little confused, sorry im deaf.. , i have ryzen 7950x and TUF x670e , in bios for undervolt i can do cpu ratio as 40 and cpu voltage as under - 0.15 ? or what are the correct settings please just for down the temperature and consumtion with a good perfomance like 5% less or something please ! :D
I have a R7 5700x and I've set my voltage to -0.102mv.
Got around 13k in Cinebench.
Temps around 50's and the performance is amazing. Thanks!!!
Finally thank you soo much 👍🏼
Do you have a stable setup for 3400g? Would be really helpful thank you
Hey brian
Are there any disadvantages to having the cpu runs at base clock for 24/7?
I do have a lot of low power activity.
I currently picked a good deal on used 3600x with x470 asus crosshair hero.
I have a very bad case so I want to keep my new cpu safe until I get a more ventilated one.
I also play mostly light gaming. But I liked that my temps got lower after trying the underclock method.
I only lowered the clock from 3800 to 3700 and I was 55 degrees on idle before and now 46. I didn't thought 100mhz could make such a different.
How much stress this will put on my cpu? and will it impact its life span on the long term?
I believe not cause the "effective clock" remains the same on low charges (not always 4.0ghz). Besides the EDC (ampere) on vrm still very low if the processor is idle.
Do you recommend undervolt from Ryzen Master or BIOS for Ryzen 5000?
Does this undervolting tutorial apply to earlier AMD Ryzen cpu's? I'm currently running a Ryzen 7 3700x on an Asus Crosshair VII board.
Wath setings you use for 5600x ?
Without undervolting you obtained the best frequency and performance or with undervolting?
For people with good cooling is necessary undervolting?
Thanks
what settings are oke for daily use and gaming? on the gigabyte x570s bios F5 for the 5800x3d ?
17:00 this part made me feel so much better about my pc. I got the 5800X and I was always at like 55-60c idle but my Gaming temps were spot on stock, so I changed my negative offset to - 0.3 from 1.42V and the 0.3 was purple and I read it was bad but you helped clarify that for me. Now I get idle temps of 35-40c with a 20c room temp. (even with the undervolt my gaming temps and performance are still great
I know you mentioned undervolting decreased performance but at this point I just want a stable PC haha. It runs faster than my old cpu, 1500X so Im happy lol
I just had my 5800x and having the same idle temps and with load it can reach up to 80c. i'll try undervolting soon and hopefully get a better temp. It's scary to see high temp on idle 😂
@@ziggyzig5666 same here with 5900x, doing this now until I can get better (and quieter) cooling for it
Will this work is in 5600h ?
You save my life thank you bro❤
Good guide, like from Brazil!
should i do this to my 5600x or oc i got a gigabyte aorus pro ax x570s would love more reviews i was suppsoed to get the mini itx sadly there is no reviews
I've been curious about undervolting my laptop due to running it on a portal power bank at times. My goal is to undervolt my CPU in order to maximize my battery by lowering power consumption. My question to you is, is undervolting safe on laptops or even possible at that? Thanks for your content as always!
That's crazy efficient. Although 4ghz is a little low for my 5700x and 4060ti combo. I pushed it to 4.55 @1.15v and it sips around 60w while gaming, stays at 60°C. I love these processors 2 years later
Hi I have a Ryzen 5700x aswell and I have high temps on some games. What did u set the core ratio to exactly as the vid shows 40.00 and how much voltage did u take away in the bios?
Games nowadays don't push the CPUs almost at all. Did you try stress tests for the cores? With 1.15V I can only achieve around 4350Mhz on full stress without getting any errors or resets. This on my 5600X. I run mine at 0.9V @3800Mhz for everything I do or 1.05V @4200Mhz when I game.
@@Sam_Bush These CPUS truly benefit from a good CPU-Cooler in case you want results. As I said above, mine runs at 4200Mhz full stressing cores with 1.05V and temps don't ever go above 60C. The original CPU-Cooler wasn't only noisy, but when you want results, it really throttles the CPU itself since it was going easily above 90C when I was trying 4400Mhz only with 1.2V. Nowadays, the smaller the lithography of the CPU, the more you're going to benefit from a good cooler. Also, you don't need an expensive one. Do a little research. The "Assassin" gives amazing results for a decent price. Easily outperforms extremely expensive coolers. Do your research, buy smartly.
@@Gyneco-Phobia Hi is my CPU cooler good enough. I got a nzxt 240mm kraken aio.
A tip to those who want to start undervolt/overclock after an upgrade of CPU :
Clear CMOS after change of CPU before starting the undervolt/overclock journey.
Else you might get unstable error when testing.
So, setting UEFI to default is not enough?
Went from 190W on my Ryzen 2700x to 130W. Thanks man.
Keep it up!
OC : @ 4Ghz, offset -0.1250V.
2700x is quite a power hog, isnt it hahah
ive been running it since 2018, beautiful cpu with its performance being to able to run full blast even on low-end mobos
My older Zen2 Ryzen 9 3900X crashed at -0.15V offset undervolting at stock clock but runs stable at -0.1V offset. Left the clock alone to let the CPU ramp up the speed on demand as usual. Cinebench gave me 18400 points, not that bad for a system I build 2 1/2 years ago :)
Is it ideal to undervolt the Ryzen 7 5800X ? I primarily game and content create on the machine. I just don't wanna lose gaming performance but the fact its reached 82C before concerns me
I have been searching to find out the idle power consumption of the Ryzen 5 5500 (or similar CPU) for days now without much success. I've read numerous written reviews also watched some other similar videos, and nothing. Now I just wanted to check how I can try to tune in some additional power saving settings, but I also found what I was looking for (package power ~10W or even less). So it seems the idle is pretty good on this R5 5500, my R3 3100 consumes more than 2 times that in Energy saving mode (~25W) which is already down from the normal mode(30+ W, way too much imho), so I guess this means it makes sense for me to buy an R5 5500 to save on energy bills. Great video, thanks.
Great video very helpful
I have been following your videos for years and I especially like this one more because I have a ryzen 9 5900x and your advice helps me to perform undervolt, I have two ddr4 3600 memories of 16 gb each, do you think it is possible to put another two to make a total 64 gb in 4 memories or someone else who can answer me.
Wouldnt it be faster to pick a "likely borderline" offset and perform a sort of binary search to find the sweet spot?
This is awesome! but there's nothing more frustrating or envious, than going in excited with undorvolting and then realizing your cpu is below average in terms of silicon lottery lol
Don't you do any stress tests like Prime95 or several things at the same time? If in some games it does not crash, it does not imply that it is 100% stable.
Doing undervolt by offset doesn't lower the same voltage in all states? Or does it always go to 4Ghz?
I have read comments about PBO and curves, I don't know what they are talking about.
Hi man! as a complete noob on this topic I found your video really helpful. But I have a question.
If the goal is " achieve the best performance while diminishing power consumption and temps" why you capped first the clock speed at 4.0? ... I would say... It was not better to start undervolting staying with the max clock speed and after, in case of instability (too much undervolt) try to diminish the max clock speed to see if capping the clock speed the processor work with less volt ?
Thank you so much for your content.
PS: sorry for my bad english... I'm italian! big hug!
What about negative curve? Isn't that the better way to do it, if you're using 5000 series CPU? I personally did -30 on my 5600 and it works flawlessly (I'm cooling it with Wraith Spire @ 1200 RPM)
Managed to undervolt my 5600g using your method (4.1ghz -200mv), and an ffmpeg benchmark encode comparison....
5600g auto = 1330.86s (33.02 fps)
5600g u/v = 1348.19s (32.60 fps)
Meanwhile my temperatures from stock cooler went from 77 deg C to 55 deg C. Perfect! I'm using Linux for this, but in windows i did notice i've shaved off ~ 30-35watts power at load. I think the idle watts were less noticable,, i'm not sure if it's placebo, but it seemed to idle from 20-25w, down to 15-20w. I will probably check this later with power drawn from the wall and see what the difference is there, but i'm pretty happy with the performance gains, thanks :)
Good afternoon, do I need to disable pbo and curve optimizer at the same time?
I want to thank you because I knew very little about over and underclocking for the e past year. I’ve been running my CPU at 85 to 90 Celsius for the last year. I am now getting 68-70 degrees as well as better performance with my ryzen 5 5600X.
I am also getting a significant degrease in power consumption, going from 75W down to around 45W
Did you set all core ratio to 40 (4.0ghz) like his or let it auto (which is 3.8ghz base clock and 4.6ghz boost clock)?
@@hquan1 went from 4.6 default down to 4.0 like his
Managed to get a stable undervolt on my ryzen 9 5900x on Asus x570 mini itx mb to -0.100 mv.
Max temps just under 60c with cores running at 62.44 W, package at 102.98 W which is about a 20% reduction. Not bad. Will keep these settings until I get a bsod.
Cinebench 23 gave me a score of 19448* about a 2% drop.
Fantastic tip and much appreciated ☺️👍
I had basically the same results with my 5900X and the same settings thats amazing
That's fantastic. Could you explain the steps to achieve this
@@mindrover777 hi mindrover777,
I basically followed
Yes Tech City's instructions using the first modest settings he described. Good luck with your attempt 👍
@@joviliro thanks 👍
Just wondering if you were ever going to put the details in for anyone running Ryzen 7 or Ryzen 9 @techyescity ?
If you use Ryzen 7 5700X you can try this.
My Ryzen 7 5700X @ 3.85GHz / 0.9375V
Same performance as stock around 13.2XX points (according Cinebench R23)
But much Less power @63W Max and Less Heat @62°C Max
Compare to stock that draw 78W Power and Pump 72°C
I'm using Cooler from Thermalright (Assassin X 120 Refined SE)
I undervolted my R7 2700X with an offset of -0.11250V and saved 43W at max while running Cinebench 20, went from 133W to 90W. The score went from 3762 to 3718 so its hardly any perf drop. My CPU max temp went from 79C to 62C. this was the limit with my system though, any less voltage and it wouldn't post.
Hey so i have a 5800x3D and i did the exact same you did. I did 4ghz and im at .15 undervolt. Xan i be doing anything else to make it even cooler and perform even better?
Ryzen master, Throttle stop or Bios? Always used bios but throttle stop is amazing.I think you can do faster finding of offset with TS without restarting then when you find it just use same offset in Bios. :)
Can the same be achieved using PBO - lowering PPT/TDC/EDC and applying a Curve Optimizer?
Of 79-82°C to 57-59°C on ryzen 5600 whit cooler stock. Thanks. Reallt good video.
The performance is more stable now. No fps drops.
Can you explain how to works with the kernel. i have seen that when the computer is long off the kernel must be loaded. but when restarts a pc , the kernel is active ,. thats explaines the fast boot. So my question how fast boot after for example a day off because the load times with my computer two times. And i have some dark screens while loading the windows 10.
Voltage doesn't affect performance right - only Power Draw and Temperature? Clock speed is what will give me higher/lower score in games/benchmarks?
Nice job!
amazing video, can you do a tutorial but with PBO? all i know is that you undervolt? all cores separately and that lets the cpu to get higher clock speed and performance with power consumpion and temps lowered. i'll be buying 5700x soon and want to get it done properly. cheers
From my experience PBO is trash and will dramatically shorten the lifespan of your CPU
I spent a couple hours with the curve optimiser on my 5900X system and had pretty good results. Went from the ludicrous 200 watts @ 85 celcius my Aorus master was pumping in to 145 watts @60 celcius and kept all the performance.
Pretty huge bump in efficiency there
Curve Optimiser is the best way to undervolt Ryzen.
@@Lord_RFAS It is more an overclock. With less voltage you get higher clocks until the core limit. PBO Limits are a wall, so it kinds of hold voltages and consumption. But yes it is a great way to get some performance with the same consumption.
