I recommend for overclocking CPUs and GPUs to start with just increasing the clock frequency alone and keep the voltage the same. The voltage has always been chosen extremely conservatively given that all the samples need to work with it, even the worst ones. You are likely to get a substantial overclock @stock voltage, only after the system become unstable at a certain clock frequency I would start to increase the voltage to whatever value you are comfortable with (safety hardware and heat), but with small increments (why use more than what is required?). Nobody should be hesitant to overclock, just be aware that you need to do a little bit of research before you stat changing the voltage. :)
Im just gonna go ask the dumb question: Whats the harm in raising the voltage above whats necessary beyond increased heat output? Do things actually burn out that quickly from getting overvolted or is it just life expectancy?
@@builder396 builder396 P=V*I = V*(V/R). Higher voltage, more than proportionate higher power. Typically around 4 times the power for 2 times the voltage in the zone where desktop-CPU's are clocked. It is the heat which COULD be the problem. If you cool the CPU/GPU with liquid nitrogen then you can safely use much higher voltages than with aircooling or an AIO. Practically speaking, I would not increase the voltage much, focus on trying to get a higher clock frequency at the same voltage. Or maybe even see if you get away with a lower voltage and the same clock frequency. A lower electrical power is nice: less noise and less heat. How high the voltage can be depends on the used process, for Ryzen1/2 you can safely clock up to 1.4 V, for Zen2 (3700X, 3600X...) for all core you best don't go above 1.3-1.35 V. What happens if you go too far? After a few years you will notice degraded performance. It will keep working but you will loose your overclock and if you push it really far then you might need to clok the CPU/GPU lower than out of the box settings. As long as you keep the voltage identical it is perfectly safe to change the clock-frequencies. In the worst case your system crashes and that does not do any damage. For AMD you can easily find the recommended voltages, for Intel I haven't found those (I haven't searched though). Life-expectancy really is not an issue at all, CPU's can last a lot longer than how long people use it. You have to do crazy stuff to not have a CPU last 10+ years.
Great video for those who want to try overclocking in a safe way. As the popularity of SBC's continues to grow, I'm beginning to think that Noctua and other fan/heatsink manufacturers should look at mass producing SBC cases with their cooling units built-in, as you have done, Chris. Inexpensive to make and a very good way for them to market their brand.
The powers that be will be on to you for being radicalised by your Pi Chris. Just saying :-) I think you had the same amount of fun making that as we did watching. Brilliant as usual!
Thank for another interesting video on the Raspberry Pi. I am thankful for the time and thought goes in your videos. I am also thankful for your demonstrations of things I would not necessary try myself - I don't like living on the edge with my computer equipment. Someone suggested a video on demonstration of water cooling on the Raspberry Pi and I think that would an interesting video too.
The 1.55 is a great score, keeping in mind that originally it had 1.2 so Im very impressed. If only the Pi had been equipped with more ram it would be a great cheap option. Thanks for the excitement !
Great video. You can also overclock RAM and core. I have seen big difference by doing that! I am doing Neural Network and it increased the speed by 20%
Love your videos! Just wanted to say by taking cues from various setups, I am currently running two Pi 3B+ boxes, both stable at 1.6Ghz. One Pi is in the standard case that came with the Abox kit, modified to include a Noctua 40x10mm 5v fan mounted on the inside; the other is in a Flirc Gen 2 case. The Flirc case definitely runs warmer. Anyhow, if anyone is interested, below is an excerpt from my config.txt. Hopefully it works for others! arm_freq=1600 gpu_freq=525 core_freq=525 sdram_freq=525 sdram_schmoo=0x02000020 over_voltage=6 sdram_over_voltage=2 v3d_freq=525 gpu_mem=512 Fwiw, I have had both boards boot and run fairly stable at 1.71Ghz. But when I ran the Sysbench OC tests for Prime 20000 and Prime 50000, the time to complete was definitely slower than settings for 1.6Ghz. Regardless, I was completely stoked and blown away by the simple fact that it even booted!
“Welcome to Exploding Computers” ;) To be honest I think 14000mhz is amazing for the cheap little board and even tough overclocking is fun to do... why even do it (because we can!!) Great video once again!
Overclocking is of great benefit to the retro gaming community. Games that will not run well at 14000mhz are a lot more usable at 15500mhz. Nothing pushes technology faster and harder than the entertainment industry and its users.
Once again another brilliant video , to brainiacs you are quite right totally radical as radical as anything done by that skateboard fella . Thank you for the hard work again Chris already looking forward to next Sunday
Bill Nanos it depends what is “stock” and where you use them. For industrial application surly not. But for hobbyists it depends. We don’t have access to full chip spec so all we know is that 2836, 2837 and 2837B0 are a bit different chips. Known difference between 6 and 7 is change from A7 armv7 to A53 armv8. But we do not have official thermal envelope for those chips. We don’t know what is their target speed like ie. ark website for Intel chips.
You must be referring to the old, but awesome Celeron 300A! I had mine hit 600 with slightly modified cooling! But 99% of the time I kept it at 450. It made my Win 98SE really shine! 😎
Great video. I think that folks are attempting to get far too much performance out of Pi's. They forget the purpose of the machine, and try to make it into something that it isn't.
jabney8mmm yes, but there are limits for cars as well. You dont take a 1.3L Toyota yaris engine, and cram it into an F250, slap a turbo on it, and expect it to pull 9 seconds in 1/4 mile. Just like you would expect a PI3 to run crysis
Yidris No, but finding out where that cutoff line is is fun. And no small part of the ‘original’ purpose of RPi was education and just seeing what could be done. Saying ‘people are trying too hard to make it do things’ is silly. Making it do things .is. the point.
Jamie Norwood the only reason for the raspberry pi was education. To teach children syntax, and to educate them in how to apply syntax in order to write programs.
Computers Explained Presents: Cooking with Chris In this episode we will show how to bake a Raspberry Pi. Be careful to keep your oven’s temperature from getting too high! We’re baking, not frying. Who likes fried Pies? I don’t.
Another great vid and no doubt will have people looking to see how they can get OC'ing, how far and in future wanting you to try their ideas. Not read the comments yet but I'm suspecting it'll be full of stories of people who embraced their inner OC'ing dark warlock being to push for more magic!

Hello Chris, A big fan of your channel and videos. I've been wondering if you could do a review of a raspberry Pi cluster configuration and see what kind of differences it provides in regards to power? I've been interested in learning about the benefits of it from your perspective.
After the testing of different cooling methods, I knew this had to be next. But even with the overclocking, the temperature was way below the 70C mark. I think just the heat sink and a standard fan would do fine for all normal ops (heavy, continuous processing), and keep the system at 1.4 GHz - it didn't really make all that much difference. Pop it up to 3 or 4, and that would be impressive. This card takes a micro sd, I wonder if it'll hold up to 256 gb. I'm sort of convinced that this might be a way to go as an interface between an electronics subassembly and a main computer (better than the Pi-0 or the Chip SBC), but I still have a lot of circuit board to make work. I could probably get all of the usefulness out of just integrating a CPU into the electronics subassembly. Hard to decide. Less programming is better, but I still need a lot of it. And data storage - lots of it. An external HDD will have to do that.
With 1.6 being a step too far anything between them are small and you couldn't really trust the stability, 1.55 is the realistic maximum or perhaps even 1.5 for true peace of mind.No point in running a computer on a knife-edge when the difference would barely be noticeable.
Tell BBC2 C Barnatt is a RUclips star now, they'll have to triple the offer. Also, I tried to run my raspberry pi at 1.5 for an extended period and only found that over time, it was unstable and it crashed when it was pushed too often. Sometimes you have a processor that can overclock significantly and sometimes you get one that just falls within the specs, there's some luck to it.
Surprised you didn't try OCing it without an overvolt. That's always my first step. See what can be safely done before voltage tweaks are needed. I only needed to adjust voltage once in my OCing days, buit I'll admit I didn't do too much OCing. I would be now, but I have a locked CPU. :(
Great video! Do you know if a Pi 3 B+ (say for desired lower idle power consumption reasons) can run lower than 600 MHz or is this a "hard" lower limit? I am envisioning a network of Pi(s) that are idle 60-70% of the time but kept busy the other 30-40%.
I believe that a Pi can be underclocked -- effectively overclocking as shown here, but in reverse. Same method though. I think you can even under voltage.
Another interesting and thought provoking video. An area which I don't think you've covered is how to 'support' and close down a Pi gracefully when the supply fails or is interrupted. Having just terminally corrupted another uSD card it's something dear to my heart. I have tried various 3.7V Li-On to 5V boost circuits - TP4056-based and others, but, whilst I can get the Pi running (Pi 3), it always has the 'lightning strike' symbol, so they're not perfect. Code to shut the Pi down by connecting two GPIO pins is easy, but one needs to have power to do this! Perhaps this topic could go onyour list ? Dave
I would be curious about the power consumption (or the current measured, almost the same, as the external power should stays at 5V, so only the current should be different when we talk about power here) of Pi on different overclocked stages. I guess, it's even the possibility that power supply just not beefy enough in some scenarios especially if people use just too "weak" ones which may be even barely enough for the base clock speeds.
Great stuff again, always enjoy an overclock!, not just on a PC it seems, an SBC can get down and boogie too. Would have liked to see some more benches with your photo editing and perhaps video rendering too? Certainly, the 20-30% uplift would make it more competitive with the Tinkerboard and the other Octa Core siblings? Anyway. The first experience I had with overclocking, was, in fact, my phone. I had an HTC Sensation and was running a daily 1.4ghz, with a slight GPU bump too, which made it faster than a Galaxy S2 at the time, which was pretty remarkable. I wish those Quad core Atoms, or maybe the Exynos models could have a boost as well, not that they need it, but why not overclock? It's free performance if the cooling is there, which in the case of PC's, it is usually. Anyways, thanks for the video. Also a wee side note, I will contact you again via a new address if you are still in the middle of consolidating your emails. Cheers.
Sorry to hear that, i understand things get a bit crazy. I hope to catch you then, hopefully, this will be our chance. Please contact me closer to the time with some more solid details. I hope it isn't too far from reality, being on the other side of the world. I am determind to make it work, hope you are too. Cheers again .
Good afternoon Mister Barnatt, or do you prefer to be called Professor? Another good video. While I can understand that it is in the nature of man to want t push the limits of his toys and get more for less, I have never been a fan of overclocking for such modest returns even when the cost of a locked or blown equipment looms. It is good to know the limits if any of us chose to go the OC route. Thanks and cheers.
can you review Banana Pi R2 router/SBC? this device has been around for a while, and according to the manufacturer’s specifications this device could be the most impressive router ever made, but it is unknown for consumers how it really performs. if you ever get one of these in your hands please try it with a 1/10 Gb optical media converter.
So you have it actively cooled and only got a 150 MHz Bump? Well, I was thinking it atleast could do 1.6GHz if not even more. I am still thinking if I should buy one, or should I wait for a Pi 4 with more Power?
Enthralling as always Chris, thank you. This is clearly a noobie question, but do you have any pointers on where I should look to learn about mounting a NAS drive onto a Raspberry Pi 3 B+? I'm trying to access files on the NAS from the Pi over NFS.
Yes, this is applicable to a Pi 3B -- I tried it with a large heatsink here: ruclips.net/video/3B3AnuOmRcQ/видео.html I can't remember how high I got though.
I apologize for the inconvenience but I would like to know if you can make a video modifying the Nvidia shield tv console I would like to see if you can make it extremely cooling like the video that you made with the raspberry pi sorry for my bad english
Great video, Thanks. BTW, can Raspberry Pi run GNOME and all its apps? Personally, I like gnome more than other desktop environments(and mainly gedit and gimp) and what kind of rig you are using for video editing? I'm trying to build my own video editing workstation and I think that asking professionals would really help a lot. Thanks.
I've been using a core i7-7700 with 32G of ram and a GTX 1070 mobile GPU. But Adobe Media Encoder is still slower than what I would expect. I'm not sure whether it's because of my CPU or the lack of GPU alghorthem.
I'm trying to get a Xeon E5-2680V2 with X79 motherboard to build my workstaion, but people told me that I should go with X99 or just buy Ryzen. I'm not quite sure what should I get now.
You clearly have very high performance expectations if an i7 with 32GB and a GTX 1070 is insufficient! :) The Ryzen chips certainly offer good performance/value for money, though personally I always go Intel.
Okay and what would you choose if you have budget for a X99 chip?I'm trying to get a X99 setup cuz they are cheaper and I can save more bucks for GPU(waiting for next gen GPU and using a old card for display now)
The cpu in the 3B+ is has thermal spreading improvements but basically the same chip as the 3B. So Rpi foundation have overclocked the chip for us but put an internal hardware limit so 1.6GHz just will not boot. I'm assuming here but it fits the reality. One chap etaprime has a workable overclock to 1.57GHz, just under the "limit". Comments?
My comments are that I made it clear in the video that this it is the same SoC, just higher clocked. :) I very much doubt that there is a 1.6GHz hard coded limit. It is just that the board becomes unstable around there -- the constraint is clearly not the temperature if suitable cooled. I could not see the point to push up in 0.1 increments -- and indeed it needs to be noted that different Pis will tolerate different overclocks. So there is no such thing as a "workable overclock to 1.57GHz" that will work on all Pi 3B+s. Some may stand that, some 1.51, some maybe 1.58, etc. It just depends how their individual SoC came out of the factory! :)
Well done 👍🏻 It would be great if you can add a liquid metal thermal paste and liquid cool the pi. I know that sounds crazy and unnecessary but hey who said we should be reasonable right : D
You could probably make the 1.6 Ghz point by upping the voltage by 1 point. Having said that I am waiting for the next generation of single board computers as the current ones are just not quite powerful enough for the emulation use I want them for. I am also waiting for SSD connectors to become part of the standard feature set rather than having to use either very limited onboard memory or memory cards that were never designed for that kind of work.
ExplainingComputers Thank you for your reply All programming languages supported by Raspbian OS Linux and all supported R Pi 3 Linux can used in R Pi 3...? Like shell scripts, python, LAMP php, perl, Node.js, C/C++...etc? Can use JAVA???
Hello Christopher! You might be interested to know that ReactOS 0.4.9 version will be released soon. This version will be the first version that has almost no problems with files of huge size or amount. It means you will be able at least to install really large games and even to try them.. We fixed a lot of bugs related to filesystems and Cache controller :D. Maybe you will be in the mood to try new version...

Overclocking gives a bit more processing power - here about 10 per cent, plus about 20 per cent extra for the GPU.
Sorry I'm late. Overclocking always grabs my attention!

Great Video! What Kind of Hardware do use to capture the HDMI output of the Rapsberry Pi?
Thanks. See this video: ruclips.net/video/pocs02YuJ4k/видео.html
Surprised you didn't try OCing it without an overvolt. That's always my first step. See what can be safely done before voltage tweaks are needed. I only needed to adjust voltage once in my OCing days, buit I'll admit I didn't do too much OCing. I would be now, but I have a locked CPU. :(
And that's another freakin awesome video
Thanks.
Very interesting Chris. thank you
Did you get your gemini as yet chris?
Oh you remember well! I got an e-mail on Friday saying it had been sent out. Hopefully it will arrive tomorrow! :) And of course I will do a video.
It arrived! :) Nice box. A video will result! :)
I am the 1404th, very good video 👍👍👍
Great video! Do you know if a Pi 3 B+ (say for desired lower idle power consumption reasons) can run lower than 600 MHz or is this a "hard" lower limit? I am envisioning a network of Pi(s) that are idle 60-70% of the time but kept busy the other 30-40%.
I believe that a Pi can be underclocked -- effectively overclocking as shown here, but in reverse. Same method though. I think you can even under voltage.
Thank you for the prompt response.
I may have to try this now! For under voltage, you use negative over voltage values!
Another interesting and thought provoking video. An area which I don't think you've covered is how to 'support' and close down a Pi gracefully when the supply fails or is interrupted. Having just terminally corrupted another uSD card it's something dear to my heart. I have tried various 3.7V Li-On to 5V boost circuits - TP4056-based and others, but, whilst I can get the Pi running (Pi 3), it always has the 'lightning strike' symbol, so they're not perfect. Code to shut the Pi down by connecting two GPIO pins is easy, but one needs to have power to do this!
Perhaps this topic could go onyour list ?
Dave
A great topic. Though I'm not sure what my solution would be . . .
I just installed a barrel jack on my B+. No more under-voltage :) And why not use nano?
Excellent! :)
Great vid mate was hoping you might push that pi to 2ghz really wanted to see that and if possiblle.
I think it would have stayed within the range.
The Pi's CPU cannot support a stable system at that speed I'm afraid. Unlike in desktop PCs, the constraint is not the temperature.
why didn't you try 1.56, 1.57, 1.58 to show the limits of your pi3 setup? Really love your videos man, you got me into SBC's
Glad you're into SBCs! The extra .01s did not seem worth it. :)
Oh tosh Chris. You are totally radical!
I would be curious about the power consumption (or the current measured, almost the same, as the external power should stays at 5V, so only the current should be different when we talk about power here) of Pi on different overclocked stages. I guess, it's even the possibility that power supply just not beefy enough in some scenarios especially if people use just too "weak" ones which may be even barely enough for the base clock speeds.
I am planning a video looking at SBC power consumption . . .
Great stuff again, always enjoy an overclock!, not just on a PC it seems, an SBC can get down and boogie too. Would have liked to see some more benches with your photo editing and perhaps video rendering too? Certainly, the 20-30% uplift would make it more competitive with the Tinkerboard and the other Octa Core siblings? Anyway. The first experience I had with overclocking, was, in fact, my phone. I had an HTC Sensation and was running a daily 1.4ghz, with a slight GPU bump too, which made it faster than a Galaxy S2 at the time, which was pretty remarkable. I wish those Quad core Atoms, or maybe the Exynos models could have a boost as well, not that they need it, but why not overclock? It's free performance if the cooling is there, which in the case of PC's, it is usually. Anyways, thanks for the video. Also a wee side note, I will contact you again via a new address if you are still in the middle of consolidating your emails. Cheers.
Thanks Brett. My life will get a lot less hectic from the second week of July.
Sorry to hear that, i understand things get a bit crazy. I hope to catch you then, hopefully, this will be our chance. Please contact me closer to the time with some more solid details. I hope it isn't too far from reality, being on the other side of the world. I am determind to make it work, hope you are too. Cheers again .
Great video as always! Just a bit sad you changed your opening line because that's when I practice my Chris impression.
I'll say it right next week! :)
Can we use a peltier module along with the fan just to keep the temperatures a little lower ?
Almost certainly! :)
Pls demonstrate in detail to make raspberry pi cluster using cluster hat.
Good afternoon Mister Barnatt, or do you prefer to be called Professor? Another good video. While I can understand that it is in the nature of man to want t push the limits of his toys and get more for less, I have never been a fan of overclocking for such modest returns even when the cost of a locked or blown equipment looms. It is good to know the limits if any of us chose to go the OC route. Thanks and cheers.
Chris is fine. :)
Great as always
can you review Banana Pi R2 router/SBC?
this device has been around for a while, and according to the manufacturer’s specifications this device could be the most impressive router ever made, but it is unknown for consumers how it really performs.
if you ever get one of these in your hands please try it with a 1/10 Gb optical media converter.
So you have it actively cooled and only got a 150 MHz Bump? Well, I was thinking it atleast could do 1.6GHz if not even more. I am still thinking if I should buy one, or should I wait for a Pi 4 with more Power?
very well done.
Enthralling as always Chris, thank you. This is clearly a noobie question, but do you have any pointers on where I should look to learn about mounting a NAS drive onto a Raspberry Pi 3 B+? I'm trying to access files on the NAS from the Pi over NFS.
This is not something I have tried I'm afraid . . . though I must do so now! :)
I'll see what I can find out. Thank you
You should do a overclocking video on the Asus Tinker Board!
Noctua fans are magic
When the Pi doesn't boot with a certain overclock, just hold shift while booting to run the defaults.
Thanks for this. Very useful.
we're all radical people
when i saw the thumbnail, it thought the fan was a little chocolate and they are going to overcook it
Man I wish PC over clocking was as easy as the Pi :)
So this would also be applicable to a 3b with active cooling? Would you think it's feasible to hit 1.55 on it?
Yes, this is applicable to a Pi 3B -- I tried it with a large heatsink here: ruclips.net/video/3B3AnuOmRcQ/видео.html I can't remember how high I got though.
I apologize for the inconvenience but I would like to know if you can make a video modifying the Nvidia shield tv console I would like to see if you can make it extremely cooling like the video that you made with the raspberry pi sorry for my bad english
I'm not aware of that device I'm afraid.
I am suprised how close this cpu runs to it's architectural limit. Was expecting an 2ghz+ overclock. Now i'm both impressed and disapointed
You can get an RPi 4 up to 2.1 GHz from stock 1.5 :)
Any chance of videos of overclocking other SBC's, such as an ODROID XU4?
Good idea; noted.
Great video, Thanks.
BTW, can Raspberry Pi run GNOME and all its apps? Personally, I like gnome more than other desktop environments(and mainly gedit and gimp)
and what kind of rig you are using for video editing? I'm trying to build my own video editing workstation and I think that asking professionals would really help a lot. Thanks.
These days for video editing you ideally need an i5 (or AMD equivalent) and 8GB or more RAM, plus GT1030 or more graphics.
I've been using a core i7-7700 with 32G of ram and a GTX 1070 mobile GPU. But Adobe Media Encoder is still slower than what I would expect. I'm not sure whether it's because of my CPU or the lack of GPU alghorthem.
I'm trying to get a Xeon E5-2680V2 with X79 motherboard to build my workstaion, but people told me that I should go with X99 or just buy Ryzen. I'm not quite sure what should I get now.
You clearly have very high performance expectations if an i7 with 32GB and a GTX 1070 is insufficient! :) The Ryzen chips certainly offer good performance/value for money, though personally I always go Intel.
Okay and what would you choose if you have budget for a X99 chip?I'm trying to get a X99 setup cuz they are cheaper and I can save more bucks for GPU(waiting for next gen GPU and using a old card for display now)
The cpu in the 3B+ is has thermal spreading improvements but basically the same chip as the 3B. So Rpi foundation have overclocked the chip for us but put an internal hardware limit so 1.6GHz just will not boot. I'm assuming here but it fits the reality. One chap etaprime has a workable overclock to 1.57GHz, just under the "limit". Comments?
My comments are that I made it clear in the video that this it is the same SoC, just higher clocked. :) I very much doubt that there is a 1.6GHz hard coded limit. It is just that the board becomes unstable around there -- the constraint is clearly not the temperature if suitable cooled. I could not see the point to push up in 0.1 increments -- and indeed it needs to be noted that different Pis will tolerate different overclocks. So there is no such thing as a "workable overclock to 1.57GHz" that will work on all Pi 3B+s. Some may stand that, some 1.51, some maybe 1.58, etc. It just depends how their individual SoC came out of the factory! :)
are the magical 1.6 ghz a factory limition maybe? To stop people from radically overclocking?
Well done 👍🏻 It would be great if you can add a liquid metal thermal paste and liquid cool the pi. I know that sounds crazy and unnecessary but hey who said we should be reasonable right : D
You could always put your Pi in a mineral oil tank. I did it with mine 😎
I guess above 1.55 ghz the problem is not the thermals anymore, so even liquid nitrogen won't help you :)
Thank you!
You could probably make the 1.6 Ghz point by upping the voltage by 1 point. Having said that I am waiting for the next generation of single board computers as the current ones are just not quite powerful enough for the emulation use I want them for. I am also waiting for SSD connectors to become part of the standard feature set rather than having to use either very limited onboard memory or memory cards that were never designed for that kind of work.
Need a video of you and Techmoan talking so that I can minimize it and spend the entire time completely confused.
if i overclock only the gpu freq do i have to adjust the overvoltage as well?
Probably not. Certainly start with no overvoltage and see what the stability is like. :)

Thank you for your reply
All programming languages supported by Raspbian OS Linux and all supported R Pi 3 Linux can used in R Pi 3...? Like shell scripts, python, LAMP php, perl, Node.js, C/C++...etc? Can use JAVA???
Yes, everything that works on earlier Pis should work fine on the Pi 3 B+.
cant wait to see how everyone including Raspberry, will react to the Bolt, and when
I am indeed looking forward to the Bolt, and the LattePanda Alpha.
oh, i didnt know about that one, thanks
some thermal goo and a lil heatsink?
Hello Christopher! You might be interested to know that ReactOS 0.4.9 version will be released soon. This version will be the first version that has almost no problems with files of huge size or amount. It means you will be able at least to install really large games and even to try them..
We fixed a lot of bugs related to filesystems and Cache controller :D.
Maybe you will be in the mood to try new version...
Thanks for the update. I'll check it out. :)
I have windows 10 on a DELL lap-top. Like all your vids. Am learning as fast as i can, I'm 75 yo at this time ok ??
Learning is always good. :)
