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.

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.

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.

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.

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.
@ExplainingComputers

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. :)
@MartinWillett
6 жыл бұрын
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.

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)

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...

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!

all arm processors that i know of (even really old ones) dynamically change their clock speed, just like today's intel cpus and gpu's from both brands. very niffty concept that has mad you phone battery last a LOT longer.

I would have been interested to see how far you can take it before it crashes :)

+ExplainingComputers watched your last video but now I'm thinking: what if you use a Paltzer cooler (thermal electric generator" between the pi's processor and the heat sink either being powered by the pi itself or separate power source; using that to transfer heat. If so can you do a tutorial?

I have been thinking of doing that just for fun. The 10x10mm peltier can be had for around USD 2.00 and should work off the Pi with the existing power supply. I employ the official power supply sanctioned and prescribed by the Raspberry Pi Foundation.

alienalxclone I fought 5 if the lesser one the problem then you can fry it if you use to hot of a hearing source the pi should be fine for it though of course I used a candle as my heating source

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.
