Congratulations on the record :) For your next attempt, you could try feeding power directly to the pi, if possible. It might be current limited due to the width of the traces from the connectors to the chip. I do not know if the traces are somewhat accessible near the chip, I do not own a RPi5. Also consider downvolting as you increase frequency and/or reduce the GPU power (if possible) to give more power to the CPU part. In a (recent past) GamersNexus video with AMD, they talk about a frequency/voltage/power sweet spot that may require the voltage to be reduced to increase frequency. Overclock to infinity... and beyond :D
I’m reminded of that overclocking episode of Futurama where Bender just keeps on increasing his power draw and cooling needs. EDIT: In one episode it seems that he has a “6502” processor.
and then it exploded that tends to happen with extreme overclocks on cpu's push them hard enough and far enough and Boom they blow like any chip pushed to far
HATs off to you, Jeff! Even if it's not practical, seeing the Pi pushed to its limits gets me incredibly Amped. It's really cool all the options we have for actively dissipating heat these days, and you gotta love that, thanks to the modifiable firmware, no performance goal is too Pi in the sky.
Hey Jeff! I recently found your channel and your content is great. I have binge a good chunk of your content in the past week. You are a great guy and your passion for raspberry is outstanding lol. Keep it up!
"so i pulled out my next trick. [I'm 'bout to reach in my bag]" the houdini refference in the captions is funny lol!! also very good video! i want to try overclocking my pi 2 now, but not to this extent
Seems the suggestion I made last time wasn't needed in the end. For context: On the Pi day video I suggested hardware modding the Raspberry Pi in order to completely bypass the firmware and set the voltage manually.
You are one of the few, if not the only person that can make me watch a video that explains that I will void my warranty by following it, and still, I watch the whole thing. You are magical.
You can also massively improve stability by just cooling it down even further. Power consumption goes down and they run more efficiently at lower temperatures and as a result you get way more performance without increasing voltage.
You can also disable all clock monitors and readouts, that way the register where that info is stored is not being read out, no clockcycles wasted and you could get higher scores. And incase that os the register thats leading to the lock ups, it can improve stability
That was actually the first route I was going to try... but it's a bit more annoying on the Pi just due to the size and how few people mess with the hardware. A lot easier to damage something that way too.
@@JeffGeerling Yea, with SoCs getting more integrated and smaller, doing stuff like shunt mods and even soldering (for me) has been really hard. Speaking about soldering, sometimes I wish there's this chinese eWaste recycling firm that instead of recycling laptop CPUs and reballing them into desktop PCs, they could reball mobile SoCs like Snapdragons into a Single Board Computer/Compute Module or something instead.
Pushing the envelope of what's possible and seeing exactly how a thing breaks can tell you a lot about what your'e testing. I wouldn't call it worth it since I am pretty sure the pi foundation does even more insanity to test units, but still fun to showcase pushing the limits.
There are sellers on eBay with stock of these older wafers; they're often used for educational purposes, they are from the 70s or 80s (old enough you can use a microscope and see the whole layout!).
If you push it with CPU + GPU, or if you have USB peripherals plugged in that pull a lot of power, you can get to 15-20W even on a Pi that's not overclocked.
Raspberry pi being unstable at 1.18 volts meanwhile intel running at 1.4-1.5 V seem peculiar. Are these different type of voltage readings ? is intel just build different ?
intelcis suffering a case of panic where the competition using glue is cleaning the floor with them, keep in mind that it was not 1.5, it went over 1.6 volts on intel cpus, in fact, it is going, the microcode update is not here yet and people do not have that information intel is not built different, this is what you do when you decide that 300 watts for just the cpu is fine
Afaik there isn't a published datasheet for the BCM2712 SoC on the Pi 5. However for reference, for similar SoCs with the same ARM A76 CPU cores nominal core voltage is usually 0.75V maximum recommend 1.05V and absolute maximum 1.1V so percentage vise that's a pretty major increase. The ARM cores lower core voltage tolerances compared to x86 CPUs are likely just a side effect of them being designed for low power and high efficiency.
I achieved a full 20% overclock on an Athlon 64 using air cooling alone. It was apretty big cooler with plenty of heat pipes and a nice big fan but the fan was pretty quiet. The chip was rock solid. Best OC chip I ever had.
The reason the CPU gets unstable even at 50 degrees but running high frequencies is due to timing violations. You see, in the CPU, data travels from one register to another, this has to be precisely synced with the clock. There is a very small window of time where data has to be transferred. When you increase the clock this window gets even smaller. Now the logic inside the chip adds to its own delay. Overall, we get a timing violation and meta-stability issues in the logic circuits and viola, your chips gets into a lockup.
If you understand which voltages are which, you could over clock the ram/increase cpu dram voltages to match both. The cpu drams's volts and the ram on the pi's volts could help with a more stable and overall faster overclock. On top of that if you hardware mod and make your own power board, maybe from pcbway. You could in theory replace the power delivery system for the pi with your own board attach an actual psu and push that chip further.
RPi calls it a 'heat spreader'-it has some thermal epoxy holding it onto the flipped silicon chip, so it does a good job pulling off heat, but loses a little efficiency compared to direct die.
I recommend you take a big piece of copper or iron , throw it in the freezer and apply that directly to the decided cpu. It's not gonna stay cold for ever but at least 30 minutes so you can run the pi against the wall.
@JeffGeerling I had a quick look and they're quite cheap for such a high quality. I might buy one and see if I can get it to work with a raspberry pi! Cheers for the quick reply 👍 👌
Jeff, you should make a small oil tank fill it with transformer oil. That will significantly reduce temperatures and improve performance. I was using that solution for cryptomining and in most cases it's bit all performance from Web data.
My first attempt at over clocking was on an old core 2 duo I ended up burning out the north bridge (back when they wernt integrated into the cpu) An the computer still runs, with a slight 5% oc but it overheats the north bridge under heavy loads an shuts down
Im curious what is the max wattage of the PSU that you are using. would it be possible to run it off a different power supply that can do 30 to 40w. You did mention 20w many times during the testing for from wall.
You should solder a capacitor over the + and - on the power plug side. A lot of the errors are because of peak power draws causing under voltage. A capacitor will buffer the voltage fluctuation.
Modern Pi's have a much better onboard power section. Older ones it definitely helped to use a solid 5.25v supply with heavy wires via the GPIO. Not so sure it makes a difference on the current ones. Not extreme, but look at the uptime of this old Pi B running at 1ghz (default is 700mhz, but it does down clock to 700mhz unless loaded). It's using GPIO supplied power. Last line is the uptime: $ cat /proc/cpuinfo ; uptime processor : 0 model name : ARMv6-compatible processor rev 7 (v6l) BogoMIPS : 797.66 Features : half thumb fastmult vfp edsp java tls CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xb76 CPU revision : 7 Hardware : BCM2835 Revision : 000e Serial : 0000000...

LUV IT! CONGRATULATIONS ON BREAKING THE RECORD, JEFF! 🥳 👏👏👏👏👏👏 My 1st thought was also cooling via TEC, commonly used on RGB diode laser modules, but you beat me to the comment.
Not sure the best way to get a hold of you. I was wondering if you could use say a Pi5 8GB and make a dedicated server like DayZ? You can make a dedicated game server on just about any old PC so why not on a Pi? Just think 6 or so Dedicated Game Servers running in a rack?
I've noticed this on some of your previous videos too, but there are parts of the video, for just a second or 2, where the framerate drops and it's actually noticeable. Maybe a camera issue? Not sure if anyone else noticed?
Heh there's usually a reason the clocks are picked-though in Intel's case, the reason is usually "how can we get our benchmark one tick higher than the competition" rather than "how can we be somewhat energy efficient?"
Honestly I didn't think about how the CO2 in dry ice would make its own little gas layer when it comes into contact with the heat spreader-it would be very inefficient cooling directly because of that!
They are still great for things like sensor controls, little automations, etc. as they only use a watt or two, and have enough compute for small tasks.
That depends on your hobbies. There are plenty of dedicated server options that don't need loads of CPU and RAM that will run comfortably on a Pi 3. Music servers, some home automation stuff, dedicated webcam server for a nature camera, BBS server, ebook library server, recipes and home management, and those are just ones I know off the top of my head. There are plenty of examples for radio stuff too like a server to attach a RTL-SDR with an antenna in a weatherproof box outside or just next to a window so you can connect to it over the network. They are plenty powerful for running various signal decoders. If you are scanning stuff and aren't sure what a signal is you can output the signal to multiple pis each running a few different decoders and see which one gives you a useable output.
Hey Jeff, long time follower here. I was looking for what the best way to contact you is and couldn't find it so dropping this comment here. I'd love to see you test some of the Raspberry Pi UPS hats out there. I'm super interested in using a Raspberry Pi (be it a zero or all the way up to a 5) as a home power monitoring device of sorts and always been curious how well these small hats work and whether they're worth it vs using a traditional UPS.
Yeah, unlike most other 'hacks', this one can and will break Pis if people don't know what they're doing. A lot of people will just go for the moon on the first shot, and risk burning things up. You have to do it slowly, monitoring temps and voltages, and have a quick power shutoff, plus in the most extreme case, a fire extinguisher handy :)
I think there is a hard voltage limit of 1.1 V due to the PMIC they have used, so even with the hacked rPI FW you will only be getting 1.1 V max. You can SET a higher voltage, but if you check how much the core is actually seeing on the rail it is still 1.1 V. You would need to Epower it to get more voltage.
@JeffGeerling can you kindly review Pineboard PCI Hat with Hailo 8L and NvMe. On its official site it says pi OS can be booted from the Nvme with Hailo 8L installed
An alternative way to fry a Pi if it survives the extreme overclocking; dip it in batter, then drop it in a pot or pan of hot oil, cook until golden brown, and serve with ranch. Mmmmmm, crunchy! 😋
No longer a fan after my Pi5 self destructed with no overclock at all. I was using their cooler with the fan, and a pci-e hat with a Samsung SSD. When I attempted overclock, it would not run at all! I gave up, and kept it stock. It died during the installing of the recommended Raspbian server version. Now I can't turn it on anymore. I get both green and red lights for about a second, then it turns off again. Of course it's well past their warranty period. I think I got a bum unit. :-(

Isnt that metal on the die more of an rf can? How close is the die to the surface of that metal anyway?

If you have a 3D printer, running octoprint or even klipper is a great use for one
Maybe self-hosting a vaultwarden for your personal password management. Together with pi-hole and a file browser to simply share some files.
I saw your profile on Drupal and came here fast.
whats the case at the start? plus the other stuff like the ssd and the fans ect, it looks cool and something i may need
Hey Jeff, long time follower here. I was looking for what the best way to contact you is and couldn't find it so dropping this comment here. I'd love to see you test some of the Raspberry Pi UPS hats out there. I'm super interested in using a Raspberry Pi (be it a zero or all the way up to a 5) as a home power monitoring device of sorts and always been curious how well these small hats work and whether they're worth it vs using a traditional UPS.
I do have a few PiSugar HATs, haven't had time to test them yet :(
If you try 10ghz on the pi what will happen will it turn into a liquid?
Liquid cooling using the Raspberry Pi itself!
@@JeffGeerling more like liquid heating
@@JeffGeerling at 10Ghz you can use ablative cooling from the cpu cover
I very much appreciate you bending over backwards to warn folks not to do this.
Yeah, unlike most other 'hacks', this one can and will break Pis if people don't know what they're doing. A lot of people will just go for the moon on the first shot, and risk burning things up. You have to do it slowly, monitoring temps and voltages, and have a quick power shutoff, plus in the most extreme case, a fire extinguisher handy :)
Can you OC the memory speed? I believe the memory interface is a limitation on the pi 5 even stock.
The memory interface is definitely a bottleneck, and I don't see any way to mess with it yet.
I think there is a hard voltage limit of 1.1 V due to the PMIC they have used, so even with the hacked rPI FW you will only be getting 1.1 V max. You can SET a higher voltage, but if you check how much the core is actually seeing on the rail it is still 1.1 V. You would need to Epower it to get more voltage.
Would de-lidding and a copper heat pipe be better?
Love the video thumbnail 😂
The case and ssd hat at 0:40 what are they and where can I get them
That's the Pironman 5, and I'll be covering it on Level2Jeff soon!
That's fun! I'm curious if it would cold bug if you submerged the whole Pi in LN2 🤔lol 😅
I have considered working with someone to make a mini pot for LN2 :D
@@JeffGeerling Haha, that would be awesome!
@@JeffGeerlingLN cooled mineral spirits so the pi isn't immediately frozen?
What is your power monitor for Home Assistant?
I wish I could even overclock my Raspberry Pi 5 to 3Ghz. Anything above 2.8Ghz and it won't boot.
@JeffGeerling can you kindly review Pineboard PCI Hat with Hailo 8L and NvMe.
On its official site it says pi OS can be booted from the Nvme with Hailo 8L installed
An alternative way to fry a Pi if it survives the extreme overclocking; dip it in batter, then drop it in a pot or pan of hot oil, cook until golden brown, and serve with ranch. Mmmmmm, crunchy! 😋
This is why overclocking is so fun...
No risk, no reward!
Soo, getting ready for a Pie mining rig? :D JK, nice research and experience!

No longer a fan after my Pi5 self destructed with no overclock at all. I was using their cooler with the fan, and a pci-e hat with a Samsung SSD. When I attempted overclock, it would not run at all! I gave up, and kept it stock. It died during the installing of the recommended Raspbian server version. Now I can't turn it on anymore. I get both green and red lights for about a second, then it turns off again. Of course it's well past their warranty period. I think I got a bum unit. :-(
❤Im sure Linus and the team would be a great collaboration ❤🪙🥇🌊🎨💡💯
