- Опубликовано: 6 июл 2024
- In this video, we're going to be overclocking a stock Raspberry Pi 4B as far as possible before it gives up. I've seen a couple of Pi 4B's that have been overclocked to 2.3GHz, so I'm going to try to get this one to 2.5GHz.

I can't believe that the thermal camera can be made sooooo small at present!！Great video to show such an impressive product and brand!
Fantastic results. I mean both CPU and temperature. Even better than water cooling you made in the past for CM4 board with compute module 4. I am still waiting for a compute module. So far I bought only a CM4 board. If I will be able to buy a compute module, for sure I will record a video. Anyway you taught me ma lot of things (especially in microelectronics field). Thanks a lot for all the support you provided. It was invaluable help. Take care.
Thanks for the great feedback and hope you manage to get yourself a CM4 module soon!
Thanks man! This tool may be great to replace some heavy&costy handheld unit for the same outcome.
Great as always
Thanks Michael . My raspi 400 with usb ssd freezes .How to change the over voltage
from 6 to 7. Please share the command lines .
thanks man!
P2pro is much better than many other phone thermal imaging cameras on the market
I've run 6 Pi4s all overclocked to their individual limit.Only blew 1 up and that was from a self powered USB device. Created a difference of voltage. Pi4 4gb the highest OC was 2200 stable. It's getting close to 4 years running it at that OC. Pi4 8gb 2275 stable on the slowest. Fastest 2347. Pi5 4gb 3150 so far all day. The only glitches are the games so far. GPU 900 is most stable for pi4 and pi5, older slower pi4 866. Cooling, official power supplies and USB flash that can keep up. 400gb/s Samsung Fit or BAR work just fine for $13-16 128gb
Ohhh, looks very fit for the circut industry....
HELP! I'm not able to access these things on my Pi4. I can get to the black dialogue box, but there's no access to GPU or temperature. How can I enable all these things?
Question is how much lifespan can achieve with such overvoltage?
P2 Pro is an ideal tool for electronics enthusiasts and professionals
I'm currently running 2.45ghz stable on a rpi4B but I have had it up to 2.6ghz but it would freeze after 10 minutes. I use a portable ac/dryer and a heat sink case as the active cooling solution. It keeps the temps around 15-25°c
Current stable clock
CPU=2450mhz
GPU=900mhz
Over volt=14
Initial turbo=60
It's impressive that you found one that would boot at 2.6Ghz, even if it does lock up after a few minutes.
With scalped SOC, liquid metal for cooling.. some were able to get stable 2.5GHz. For CM4 there were news about insane 3GHz.
Still you can improve your setup with just fan blowing into whole board cooling it a bit from bottom. I would also pay attention to pmic temp.
I was always curious what is power usage on overclocked unit. Turbo mode destroys all charts for sure. ;)
Yes I've seen a CM4 module overclocked to 3.0GHz by Claude Schwartz. I didn't think to measure the power usage - I'll have a look at that on my next run.
@@MichaelKlements The whole goal of overclocking is to get as much as possible, but nobody cares how much that costs. If You loose ability to dynamically adjust frequency board will draw much more power than it's needed and therefore power per watt would be miserable. Q engeenering guys made some test on overclocking with some insights about power, but they went much lower and don't cover real world usage. I don't think that anybody is using pi fully loaded all the time 24/7, in real world maybe about 20% of time it can use high loads so down area is for me much more important than peak usage. I would be grateful for such results showing power stats! :)
I am absolutely confused, I copied your command for the benchmark 1 to 1, but my Pi does a "total number of events" of 35k+ and my latency is 1ms average, were you on a 64bit OS?
Yes, I'm using the 64-bit version of Raspberry Pi OS. Did you copy the prime number limit as well?
@@MichaelKlements yes I did, I typed the entire command to compare, maybe a different version of the tool? One thing of note is my pi is headless, not a full desktop, that... shouldnt make that huge of a diff tho right?
I actually ended up delidding the pi (suprisingly easy, the glue IHS glue is crap) and just cranking it to 2.5Ghz, so balancing performance and stability is no longer a problem with it running at 42C. Still definitely odd tho
I'm sure a different version and the fact that yours is running headless would make a difference to the results but I wouldn't have thought that the difference would be so significant.
I still need to try delidding a Pi!
Has sysbench changed how it counts events?
2.1GHz @ over_voltage=6 >> 32749
2.2GHz @ over_voltage=8 >> 34411
2.3GHz @ over_voltage=9 >> 36037
Raspbian Lite 64bit Pi4 @ 2.1GHz @ over_voltage=6 >> sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 --validate run
CPU speed:
events per second: 3273.43
General statistics:
total time: 10.0011s
total number of events: 32749
Raspbian Lite 64bit Pi4 @ 2.2GHz @ over_voltage=8 >> sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 --validate run
CPU speed:
events per second: 3439.63
General statistics:
total time: 10.0010s
total number of events: 34411
Raspbian Lite 64bit Pi4 @ 2.3GHz @ over_voltage=9 >> sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 --validate run
CPU speed:
events per second: 3602.39
General statistics:
total time: 10.0006s
total number of events: 36037
So small but powerful
You're supposed to get multiple data points. What you should really be doing is running the 1.5 GHz set of tests like 3 or even 10 times, then look at the min/max/average in case there's a fluke somewhere. Then do the same for each iteration of frequency increase.
Who cares? YOU CAN'T BUY A PI4. I love hoe Eben says they MAY be available late this year, but that is then, not now, and I've been lied to before. Lets just use a cheap x86 or a Potato and quit giving air time to company that sells the hobby community nothing while feeding their commercial customers.
I stopped at 2.1ghz and 700 frequency with gpu and at 6 overvolt. Couldn’t push it any harder unless using air conditioning.
What's the temperature? My RPI 3B+ is at 1.5ghz at 45 degrees Celsius (only fan and tiny heatsink)
@@osopenowsstudio9175 54*c, same heatsink and fan. fan is on 24/7.

@jeffgeerling needs to confirm this😮
@jeffgeerling
@@diabeticnomad what he said👆
@JeffGeerling the people want validation 😃
Haha don't worry, it does seem that some limits were lifted with later versions of the SoC. Can you confirm your board has a "C0" revision chip instead of "B0"? That's the version that was put on the CM4 and Pi 400, and they later started putting it on Pi 4 model B as they ran out of the B0 stepping.
The C0 is not substantially better (especially at base clocks), but does seem to handle overclocking at the extreme end a little better. That, plus you may have won the silicon lottery with your chip. None of mine go over 2.3 GHz and are stable at all.
That's quite interesting, I didn't know that that was even something to look out for. I can confirm that the board in the video is a B0 revision though, the last digits are "B06B0T". It is one from back when the 8GB was first released. You can see the numbers on the chip at 0:06 when it's a bit better in focus.
I understand that they also improved the PMIC on the 8GB Pi 4B (along with the CM4 and Pi 400) so that is one of the reasons why they generally do better than the other 4B variants.
