This is Raspberry Pi Brilliance at its Best! A really major, super "Thank You" for your extended efforts on the recent RPi series. Thank you for your time and effort to produce these quality pieces of work, Christopher. I wish you a great week.
I have successfully overclocked my PI 3 to 1.3 GHz. After running the stress test my temperature never went above 40.8*. Tomorrow when I get home from work I will bump it up to 1.4 GHz @1.3 volts and run the GPU at 450 Hz. I cannot wait to try this out. Thank you for anther outstanding video tutorial.
I love when I am looking for instructional videos and I see one of yours pop up because they are so direct and ALWAYS get me to what I am trying to achieve! thank you so much for all your work!
Another way to speed up everything is faster disk access times. By cloning your OS from the SD card onto a SSD installed in a USB 3 drive caddy and configuring the system so the OS runs from the SSD you can get huge reductions in boot time and program and file loading times. In this configuration the Raspberry Pi 3 can boot in 21 seconds at stock speed or less when overclocked.
Thank you for this video. It helps to prove to all those arrogant people on pi boards that a heatsink does make a difference on the pi and especially when overclocking.
Hi Friend. This video alone convinced me to start following you. I've became a huge enthusiast of the Pi world recently and I've been found your videos very handy and instructive. Cheers from Brasil!
Another excellent Raspberry Pi 3 video. The test results were very interesting with passive cooling. I would be interested to learn what was the performance difference for this test in terms of speed over an non-overclocked RPi3. I can see where overclocking may come in useful for certain intensive tasks but I would worry that it would severely reduce the overall lifespan of my RPi3.
After editing my boot/config.txt file to arm_freq=1400, my Raspberry would not go there as I ran the stress test after editing the boot/config.txt file. I ran the cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq command in another terminal window and it would only show 1300000 for the cpu speed. I cannot for the life of me figure out why it wouldn´t go to 140000. I edited the file twice and saved it twice to be sure that I had everything right. I guess whomever made my Raspberry Pi 3 wouldn´t let me overclock it that far. I´m happy with it running at 1.3 GHz and I did overclock the GPU freq=450. It still runs very cool during normal use. I can tell a difference in how fast a page loads from the standard 1.2 GHz and the GPU freq=400. Thank you for this great video tutorial. I think I´ve convinced my wife to finally let me put linux on her Windows 10 laptop. She really likes the GUI of Raspbain on my little Raspberry Pi 3! :-) Now, how do I overclock the RAM? You should do a video tutorial on that sometime. Thank you very much.
came to learn how to overclock my rasp 3. i learned how to overclock my rasp 3. thanks for the straight forward video,. though i link to download your test script would have been nice, but can't have anything. thanks for the video.
Excellent video, btw you can bump the gpu to 500 safely, possibly higher depending on power supply and heatsinks etc but some users have had issues above 500.
I enjoy your videos. It would be interesting to push the Pi until it failed. I'm curious to know what would happen if the Pi was configured to use max voltage and max buss speed, then increase processor speed until failure. It would also be interesting to graph power consumption vs. processor speed. Keep up the GREAT work!
Could you compare the overclock processing speed in terms of your timed tasks against the regular pi 3 and pi 2 speeds? It would be interesting to know what is being gained for the risk.
On my Pi 2 I put thermosetting epoxy heat conduction. It made a 3.0 c lower that the paste on my massive heat sink. I took CPU and cut it down. It sticks out the case by 45 mm. And yes I can convert inches to metric!
I have really enjoyed your videos on the raspberry pi and the cooling/overclocking! Thank you so very much. My pi 3 b+ should be here shortly. And I'm looking forward to messing about with it. BTW, I have a rsysloghost, dhcp server, ntp clock and nagios all running on a pi 2 (b+?) on a 64 gig micro sd card (class 10)! I think these things are fantastic!
I don't think I have any credentials at all to say this but I was quite surprised that you didn't keep the tests running until there was no further increase in temperature. I would suggest that only when you have seen the temperature plateau (or maybe even blip downwards a tenth of a degree) can you be confident that it is stable. In all these tests the temperature was still climbing. Of course the answer may be that you've seen other examples and have developed a confidence that the peak temperature is only fractionally higher than what is achieved after about ten minutes. I'll see myself out.
The answer is about practicalities. A Raspberry Pi is extremely unlikely to run for an extended period at full processor load, so the tests were limited in duration. Also, I am making a video here! Specifically I am recording the output form the Pi in real time to a ProRes recorder. That's about 2GB of data every minute that needs to be stored, copied over for video editing, etc. So running tests for extended periods had a significant payload. :)
ExplainingComputers Understood. It might be worth doing an extension test *once* to see how passive cooling works and whether it does reach a plateau. Once you graph that temperature climb once you will have a better grasp of how it works so you can estimate what temperature it will top out at based on the initial temperature climb.
My pi 3 is overclocked at 1.5ghz with overvoltage 5,and it is very stable but when i try to go to 1.6ghz with overvoltage max it crush after a few minutes from the boot.But the temperatues are a little dangerous because at 1.5ghz(with a heatsink) it keeps at 80-90° and sometimes at 100°,with a heatsink+40mm fan it keeps the 70°max.But at 1.4ghz overvoltage 4 it is stable
I have a 5V0.2A fan and a heatsink on all the hot chips, playing youtube videos on 1080p it stablizes at around 53C at 1.35GHz, should I try to push to 1.5Ghz?
What you need to do, is run a thermal camera on these boards. When overclocking, some chips on the board, and voltage regulators, get really hot; and need additional cooling too; not only the CPU.
When you run your sysbench command if you were to put time in front of the command it would tell you how long it took to run -- would be interesting to see how long it took at each overclock setting. time sysbench
Your final overclocking wasn't quite representative - the temp was still increasing by over 2 degrees per sample. Did you carry on the experiment till it plateaued?
Chris, do you have an example program you could show us to compare this speed increase in the real world i.e. graphics performance. Thanks for another informative video.
If it throttles at a certain temperature for safety, does that make it harmless to put an arbitrarily large number in there to determine quickly how fast your unit can go?
Underclocking. My Pi3 runs very hot doing some signal processing (tracking very weak (0.01 watts) glider anti-collision warning systems with sensitive receivers), but much is done by the GPU. I assume I could minimize the heating by underclocking the CPU to 1000 or 1100 MHz using these techniques? I am also getting a BIQU Aluminum Raspberry Pi 3 Case Enclosure Box with metal pads attached to the case from the CPU/GPU/RAM to cool the thing down. If underclocking is not desirable I'd like to know before I toast my Pi3... I am a techno-bozo... and a real fan of your videos!
Hi Christopher, it is recommended to have a 2A power supply for the Pi 3 especially when overclocking, it would be interesting to see a video where performance is measured when 1A, 2A and above power supplies are used to see if it would vary?
I'm curious about that "cat" 🐱 command you're using to indicate the CPU speed. Is that number actually stored in a *physical* file? On the micro SD card? It sure seems that rewriting that number to a file every time the SOC throttles and resumes would really slow 🐌 things down and prematurely wear out your memory card! Or are they writing to a RAM disk?
thank you for taking the time to make and SHARE this. i want to mount my RPi3 in the freezer now... and well... you know... 2.5ghz haha... im sure 2.5ghz is just around the bend anyway haha... ty for a great video
A little overclocking seems like a good way to really test the custom heatsink. ( OT: Did MS eliminate the ability to set default font and font size in Mail in Windows 10? )
my HDMI is working but I want to use VGA instead for my display can u make a separate video on it for my display for raspberry pi 3 I took a peek on this video and I saw (#force vga output to) uncomment in order for it to work . WILL IT??????😃 OR NO😔???????
Actually, you shouldn't let it cool-down, and should keep it running until saturated with heat. That will let you know how sufficient it is cooling, while in constant high-load. Letting it cool is just masking the true "leveled-off temperatures". Eg, it never got up to "saturated load temps". That is like throwing it in the freezer and stopping the test when it rises to 10c, and saying, "Look how cool it runs at this speed!" When you hit the same temp for ten cycles of tests, then you are at the saturation level. If there is a change from the second-to-last, and the last test, and it is still rising... Then it isn't "done".
I was thinking: - How much does ambient temperature influence the results. - Not everyone would have such a big heat sink on their Pi what about with a small heat sink (the one that comes with a zebra case for example) or no heat sink at all. - what is the max temperature the CPU is rated for? - is there a failsafe in the Pi that will reduce the clock frequency if a certain temp is reached? Maybe a good idea to also get the clock frequency with the temp. As for measuring: make 2 programs... one that maxes out the CPU for let's say 10 minutes and another program that takes a snapshot every second or so to see the curve on a few stats. Put the results into a CSV and create an graph in an spreadsheet program in a few seconds. (or into a SQL lite database and turn it into a nice graph with your language of choice. PHP and the Google Chart API's for example). Here is an example how this could look: vampier.net/pingmonitor/ (this time with pings over time)
At what temperature would we be worried? How high can the temp go safely? How far past 1.4 can you push the system, I assume you have tried before since you weren't willing to push it further. Can the GPU be overclocked Further?
+ExplainingComputers Hi. Thank you very much for the video. I have a problem with 4:08 the file didn't open. Do you have any suggestion what to do in this case ? I also tried overclock it with Raspberry Pi Software Configuration Tool but when I tried it says "This Pi cannot be overclocked." and then "There was an error running option 8 Overclock " Thank you.
great video, but i want to ask one thing, i am pretty new to the raspberry pi, i´ve bought it only a week ago, but does this work with the raspberry pi 3 model b as well? And if yes, is it the same process or something different? I´ve heard that raspberry pi 3 and pi 3 model B is the same thing from some people, but others say it is not. Thanks!
There is only one Raspberry Pi 3, and technically it is the Raspberry Pi Model B. But there is no model A. The first ever Raspberry Pi computers came as model A or model B. But the Pi 2 and Pi 2 are model B only. So a Raspberry Pi 3 and Pi 3 model B are the same thing. :)
Many thanks for another interesting video about the pi. Do you think it is possible to go up even higher, let's say 1.5 MHz? Would underclocking save energy? Or would it be possible to reduce the idle speed from 600 MHz down to let's say 400 MHz?
I could not get above 1.4GHz. Somebody in the comments here achieved it -- it will be luck of the draw on the Pi you have. Underclocking would indeed save power, and is an interesting idea! :)
I do not really need to overclock my pi, at least not yet ;-) (I'll have to buy a new one anyway) But I think I could underclock my pi3, as it runs with volumio, which is a free audiophile music player software based on raspbian, that would run on every version of the pi and does not need much ressources.
For those wondering: sudo vim /boot/config.txt or sudo nano /boot/config.txt respectively just opening that file with any editor as 'root'- seems to work - instead of going over this 'idle' thingy :)
ExplainingComputers Yeah, I just got confused .. not knowing 'idle' :) Seems to be for programming that unit .. actually you made up videos about that already iirc ;)
And can you do a video how a smartphone battery communicates with the phone because I want to bypass the battery of my old phone but I don't know how it communicates
I may be completely wrong but surely overclocking the GPU and then running a CPU only (?) stress test will have no affect on temperature? Wouldn't you need to test both at the same time to see the true max temps? Brilliant video though, keep up the good work.
You are of course right on the GPU-not-being-stressed point -- though its extra clock speed (it is still running at 450GHz in the last test) could impact the heat generated.
Ah I see. Just out of interest though, is there any way of bench testing the CPU and/or GPU to see how much extra performance those overclocks do to the processors?
That 40nm process is not helping the Pi here when it cones to overclocking. I tended to regard the Cortex A53 as quite frugal, yet on 40nm, they're pretty hungry for power.
You can get away with not letting the heatsink not completely cool be measuring delta T rather than absolute T, so you can see how much the temperature has risen by than what it peaks at
I wish you would have done something w the SDRAM too & possibly touched on GPU memory allocation. Before I even looked at overclocking, I adjusted the GPU memory allocation up to ~256...then I saw this, did the final set of OC instructions, which worked perfect, then I slightly bumped up SDRAM freq & the title bar wouldn't load...(?). Commenting out my SDRAM freq change, and no real issues. The wiki has a great deal of information, which helps...but your vids are always pretty clear cut - 'do this, this, & that, & here's something that works' .....I think that's a direct quote from one of your vids if I'm not mistaken.....(?). Anyhow, you may already have done it & I just need to search a bit; needless to say, I don't want to get into codependent mathematics & such the wiki focuses on just to insert a discreet number for the title bar to load... Otherwise, good stuff - this shows the flexibility/adaptability of the RPi, even in the face of all the brute hardware China can/is throw(ing) at it...
the warnings are correct but most modern computers with overclockable motherboards will resist hardware failure from a bad overclock. Not saying its impossible anymore but it is unlikely. However this is on a regular pc not a pi
to really find out if the overclocking works . .you need to do things like get on you tube and watch a clip . . and while watching maximise and minimise the screen . just one way to find out if ur overclocking worked
+ExplainingComputers i didn't imply you weren't, i thought you might make it when your finish research and after the other videos you have lined up. And rpi videos are great cause someone finds something new that can benefit everyone.
Thinking about building a mini arcade cab with the Pi. Would it be a unnecessary, risky waste of time to OC that? I'm sure it runs roms fine, I'm just getting off on the idea lol
Not necessary. Risky, but not too much if you are careful. And certainly part of the Pi experience! The Pi allows you to try stuff you would not on another PC. :)
I need to know if you can run raspberry on Rock 64 can you run the Lenox raspberry software on Rock 64 or should I just get a raspberry device because I'm new and wanted to try this and God a rock 64 because it was supposed to be better but the community is to small
So I use my pi for gaming especially for PS1, but some games could run a bit better so if I change it to overclock at 1300 without sink just factory stuff I would be fine and my games run better? I'm a total noob at this just a enthusiastic gamer

Why over clock the GPU and then never stress test the GPU? The real test here should have been CPU and GPU at 100%
I love when I am looking for instructional videos and I see one of yours pop up because they are so direct and ALWAYS get me to what I am trying to achieve! thank you so much for all your work!
Even if I know all the basics I still enjoy watching your videos. You are making boring stuff enjoyable.
Brilliant vid. Attention to detail with production is sublime and makes this vid on par with top professional broadcast productions.

In this configuration the Raspberry Pi 3 can boot in 21 seconds at stock speed or less when overclocked.
I don't think the RPi supports SuperSpeed USB (and it proballly wont), but regardless this idea might still work.
The Pi 3 does not support USB 3.0, so it's kind of pointless unless you use USB 2.0
Thank you for this video. It helps to prove to all those arrogant people on pi boards that a heatsink does make a difference on the pi and especially when overclocking.

Good one. I like your trudging through the details of the experiment and the thought process behind your choices. Great learning tool.
I wondered about TE coolers? Great video by the way.
What about 1.3 ghz? Seems like a very safe middle ground with a good heatsink and extra power. I also have no idea about computers just wondering.

I think that it might be a good idea to use a Corsair AIO water block and radiator and try and get as much of the generated heat out of the core.

+シッセンエリック No, it is not the heat that is making it unstable.

I also tried overclock it with Raspberry Pi Software Configuration Tool but when I tried it says "This Pi cannot be overclocked." and then "There was an error running option 8 Overclock " Thank you.
well you should test the performance of the overclock
great video, but i want to ask one thing,
i am pretty new to the raspberry pi, i´ve bought it only a week ago, but does this work with the raspberry pi 3 model b as well? And if yes, is it the same process or something different? I´ve heard that raspberry pi 3 and pi 3 model B is the same thing from some people, but others say it is not. Thanks!
There is only one Raspberry Pi 3, and technically it is the Raspberry Pi Model B. But there is no model A. The first ever Raspberry Pi computers came as model A or model B. But the Pi 2 and Pi 2 are model B only. So a Raspberry Pi 3 and Pi 3 model B are the same thing. :)
Ok, thanks
Many thanks for another interesting video about the pi.
Do you think it is possible to go up even higher, let's say 1.5 MHz?
Would underclocking save energy? Or would it be possible to reduce the idle speed from 600 MHz down to let's say 400 MHz?
I could not get above 1.4GHz. Somebody in the comments here achieved it -- it will be luck of the draw on the Pi you have. Underclocking would indeed save power, and is an interesting idea! :)
I do not really need to overclock my pi, at least not yet ;-) (I'll have to buy a new one anyway)
But I think I could underclock my pi3, as it runs with volumio, which is a free audiophile music player software based on raspbian, that would run on every version of the pi and does not need much ressources.
e1woqf I will now checkout Volumio -- thanks! :)
Again a perfect video
For those wondering: sudo vim /boot/config.txt or sudo nano /boot/config.txt respectively just opening that file with any editor as 'root'- seems to work - instead of going over this 'idle' thingy :)
As I said very clearly in the video, there are loads of ways of editing the config file! :)
ExplainingComputers
Yeah, I just got confused .. not knowing 'idle' :) Seems to be for programming that unit .. actually you made up videos about that already iirc ;)
Cacalari Bus I mainly used idle here because I had some nice, large fonts and highlight colours already set, so it would read well on screen. :)
And can you do a video how a smartphone battery communicates with the phone because I want to bypass the battery of my old phone but I don't know how it communicates
Is it Possible to use this Rasp Berry Pi 3 for web hosting would like to know Thanks.
Even though I really enjoyed this video,
you Sir, have committed a cardinal sin!
7:20 DIR? disgusting.
LOL
tree ;-]
Hemanya Sharma hm... lets go creazy with 'ranger' ;-p
In former times, on my early SuSE systems, "dir" was an alias for "ls -la", set in /etc/bash.bashrc (if I remember correctly).
I may be completely wrong but surely overclocking the GPU and then running a CPU only (?) stress test will have no affect on temperature?
Wouldn't you need to test both at the same time to see the true max temps?
Brilliant video though, keep up the good work.
You are of course right on the GPU-not-being-stressed point -- though its extra clock speed (it is still running at 450GHz in the last test) could impact the heat generated.
Ah I see.
Just out of interest though, is there any way of bench testing the CPU and/or GPU to see how much extra performance those overclocks do to the processors?
That 40nm process is not helping the Pi here when it cones to overclocking. I tended to regard the Cortex A53 as quite frugal, yet on 40nm, they're pretty hungry for power.
hey...can u make a video which remote raspberry pi 3 using inbuid wifi...pls
I've overclocked many CPU's. Still, I get extremely nervous at the BIOS changing multipliers and FSB speeds :)
You can get away with not letting the heatsink not completely cool be measuring delta T rather than absolute T, so you can see how much the temperature has risen by than what it peaks at
I wonder what the cpu temp would be after a good shot of canned air?
I wish you would have done something w the SDRAM too & possibly touched on GPU memory allocation. Before I even looked at overclocking, I adjusted the GPU memory allocation up to ~256...then I saw this, did the final set of OC instructions, which worked perfect, then I slightly bumped up SDRAM freq & the title bar wouldn't load...(?).
Commenting out my SDRAM freq change, and no real issues. The wiki has a great deal of information, which helps...but your vids are always pretty clear cut - 'do this, this, & that, & here's something that works' .....I think that's a direct quote from one of your vids if I'm not mistaken.....(?).
Anyhow, you may already have done it & I just need to search a bit; needless to say, I don't want to get into codependent mathematics & such the wiki focuses on just to insert a discreet number for the title bar to load...
Otherwise, good stuff - this shows the flexibility/adaptability of the RPi, even in the face of all the brute hardware China can/is throw(ing) at it...
I could always do more! :)
should I install a little fan?
Sir please share link for heat sink for purchase thank you
The heat sink was from an old motherboard.
Will it under volt?
I don't know, underclocking is possible though
y!?
To reduce heat and power consumption
once I underclocked my Pi to 100 MHz, works well just slow af.
Can you make a video about the composite output and VGA conversion because i don't have screen with HDMI.
Good idea -- noted. :)
I overclocked my speak and spell and now it talks like the micro machines guy
:)
Could you OC the CPU/GPU like he's done with a FLIRC case or would the temps get too hot?
the warnings are correct but most modern computers with overclockable motherboards will resist hardware failure from a bad overclock. Not saying its impossible anymore but it is unlikely. However this is on a regular pc not a pi
do you have benchmark for apps after overclocking?
This works with Raspberry Pi 2 too, I got mine at 1.4 GHz
Update: Tested 1.45 GHz and it shows random colors on the screen
:)
I think you killed it. Better off buying 3 b+ which is already preset to run at 1.4 GHz
butcanitruncrysis3at4k60fps?
Daisuken nou
to really find out if the overclocking works . .you need to do things like get on you tube and watch a clip . . and while watching maximise and minimise the screen . just one way to find out if ur overclocking worked
David Young Yes, but not gpu
great video, are you planning to make one about how to change the current on the rpi 3 usb ports?
It is not currently on my list . . .
+ExplainingComputers maybe down the line, have a great day
Oh yes, I never say "never" -- especially when it comes to Raspberry Pi videos. Not everybody likes them, but they remain my most popular.
+ExplainingComputers i didn't imply you weren't, i thought you might make it when your finish research and after the other videos you have lined up. And rpi videos are great cause someone finds something new that can benefit everyone.
i can overcloking to 2ghz?with nitrogen liquit ?
I doubt it. The constraint is not the temperature.
Wait, the Pi comes with a warranty? I've had mine for a year and I didn't even know.
Use LN2 and OC it to 5ghz.
Hi @ExplainingComputers I have a question, if there are two raspi 3s and you make them a cluster computer, would the performance be doubled ?
If the software could fully take advantage of the processing power, yes.
Thinking about building a mini arcade cab with the Pi. Would it be a unnecessary, risky waste of time to OC that? I'm sure it runs roms fine, I'm just getting off on the idea lol
Not necessary. Risky, but not too much if you are careful. And certainly part of the Pi experience! The Pi allows you to try stuff you would not on another PC. :)
Cant find heat sink.Where did you find it?
I need to know if you can run raspberry on Rock 64 can you run the Lenox raspberry software on Rock 64 or should I just get a raspberry device because I'm new and wanted to try this and God a rock 64 because it was supposed to be better but the community is to small
nice video..continue ur research on pi.....
So I use my pi for gaming especially for PS1, but some games could run a bit better so if I change it to overclock at 1300 without sink just factory stuff I would be fine and my games run better? I'm a total noob at this just a enthusiastic gamer
loking forward to pi4. probably usb 3.1, gigabit ethernet, and 2GHz processor speed.
Brilliant vid mate
How reliable is the pi
