This cooler is great looking but for those that want a cleaner setup the "heatsink" style cases like the Flirc and Argon One will get you to very similar overclocks without the Pi resorting to thermal throttling.
Thanks. It's one of the best things about doing the channel. I'm working on a software project to make it easier to manage the comments coming in so I don't miss so many!
Amazing, clear, and concise video. Could you please specify what power supply you use for your Raspberry Pi 4? (What is the best power supply to use if overclocking to 2.1GHz?) Thank you.
I'd like to know this as well. Online listings don't show watts, only volts and amps so it's hard to pick one. I'm currently using a 5V 3A power supply and it can handle a bit of stress at 2.1GHz but dies after a minute of continuous stress.
Latest I’ve reached with 2 Pi4 4Gb with latest buster build and rpi-update for latest firmware. Force_turbo=1 Over_voltage=7 Arm_freq=2140 Gpu_freq=800 Gpu_mem=512 Hdmi_enable_4k=1 Hdmi_enable_4kp60=1 97F temp - wicked aluminum case no fan. Playing 4K video h265, h264, hevc, 7.1 audio. Stable 11 days. WiFi, NIC and BT stable also.
When you said you should have a stable power supply for that configuration, would the official raspberry pi 4 power supply be considered stable enough? And does this overclocking method work on raspberry pi Noobs?
yes & yes, many of the kit / official psus are over-capable. The cheap or random phone ones sometimes work great, until you overclock or add some USB devices & then they fail.
@@ophionnox1582 Yea they're fine, I think the PSU is rated 3000mA. In reality an overclocked pi uses around 1000mA at max load.. when USBs and fans are added it starts to bump up a bit, but the PSU is still well capable.
there’s something pretty odd going on here. with no active cooling but OCd 1.75HGz there’s no benefit?! that suggests your ffmpeg test is thermally throttling at both 1.5 & 1.75 GHz? and at 2.1 GHz without active cooling you loose performance? so that’s power throttling kicking in? and at 2.1GHz active cooling you’re over clocking by a whopping 40%, but only getting ~13.5% reduction in encode time? That means your app is bottlenecked somewhere else. weird.
hi i was wondering what exactly is the benefit if over clocking the gpu please? struggling to find a good answer. does it help with performance or just less stuttery video?
I noticed that most people that have the Ice Tower fan purchased the silver one(at least in all the vids I've seen.) I got the black one. I was wondering if the coat of black paint over the copper heat-pipe slightly reduces thermal transfer. Do you think thats why most people purchased the silver one with exposed copper?
That's why I got the silver one. Didn't like the black paint or the black coating over the copper. If it were anodized rather than painted I'd have gotten black (because that arguably would be more effective at absorbing heat), but since it is painted and has that coating over the copper, i went for silver instead. The effect is probably negligable, but since I'm getting it to transfer heat, I opted for what I thought would be the most effective at that.
Would this technique also work fine for underclocking the pi? I would be curious to see how much battery life could be stretched by making the pi a little less power hungry. I've looked around a little and have seen very little focus on power use optimization which is going to be very useful if I start carrying a pi on me everywhere
Underclocking usually doesnt improve energy usage that much. But you could try undervolting and disabling interfaces you dont need, running headless, etc.
Out of scope of this cool presentation 🥶, but in your video you are talking of your security cam stack. I'm interested to know more, are you will talk about it ?
Tech Craft I agree. I’d love to see your video camera setup. I’ve been building a video camera using a RPi0w and my older RPi3B as the backend/encoder, but both seem a bit under-powered. I just bought a Pi3A+ to utilize its extra horsepower as the video camera module, and I’m considering buying a Pi4B for the backend/encoder. Thanks for your RPi videos.
It’s not super stable for me, especially at the 2.1Ghz level. I need to do more testing, but I think it’s better to use extra power. Next week I’m posting a review of a hub that has an extra USB-C socket that allows for the Pi and the iPad to both be powered, even when the Pi is overclocked.
Retropie will benefit a lot from overclocking - on the more complex emulators like Dreamcast, N64, PSP etc. For media centre it will make no real difference.
@@Daz555Daz Yep overclocking the gpu makes a big difference.. also worth noting the new vc4 fkms driver breaks kodi but works wonders for psp & n64 emulation. It'll be a while until kodi is fixed even the alpha version isn't working on that. But you can switch between them on a reboot.
you could do this by setting "force_turbo=1" in the config file.... HOWEVER that is completely unnecessary for most applications, gains no enhanced user experience and voids your warranty by setting a sticky bit. so don't do it.
@@justusbenning1626 What are you talking about? anyway: Yes what you're looking for is the option "arm_freq_min" which will set the ondemand governor to only go that low.... or the CPU GOVERNOR www.raspberrypi.org/documentation/configuration/config-txt/overclocking.md The linux Governor has many settings, most known are ondemand & performance.

This is the best. If you want max performance due to quick switching and latency of the governor on your program, then performance may be of interest to you. Nearly every operating system (including windows) has these things. wiki.debian.org/CpuFrequencyScaling raspberrypi.stackexchange.com/questions/9034/how-to-change-the-default-governor
That's because you can get better performance than this one by just blowing a 50mm fan directly onto the pcb and threading it through some of the pi screw holes. keeping the entire thing cool is always going to be much more beneficial
@@tech_craft That's some of them, not all of them. However to answer Landy 5000, it depends on your GPU task. The h264 is for a gpu video decoding of h264 encoded video... and a v3d would be if you are trying to measure your GPU clock during a game or animation on the web etc.
I've done some camera projects with the Pi and I'm planning a video about building a camera setup to monitor my 3D printer which is pretty close to the surveillance camera setup.
@@moj8945 I was considering that as an approach for detecting that the printer has stopped the job. I'm still working through it, but if I get that in the final solution I'll be sure to include it in the tutorial.
Do you use this fan when you go mobile with your PI? What does your mobile PI look like? Just trying to figure out how to balance overclocking and mobility. This video shows a nice 3D printer case for the PI4 with this fan. ua-cam.com/video/TFpoVwrw3Pc/v-deo.html
I was using this case (tinyurl.com/y2hqvnbn) for mobile usage, but I dropped it and the corners have come off. It’s great for heat management, but it’s a little unwieldy for my tastes. I’ve just ordered a heatsink case (tinyurl.com/ubsjyh4) which according to the blurb offers 10-15C passive cooling under load. If that’s true, then I think this might be the case I stick with.
@@DavidJohnson-zv5ir If I can get it to stay stable at a sensible temperature I absolutely will. It won't be at 2.1GHz because the power draw is a bit too much, but at 1.75GHz I think it's feasible if the passive cooling case does a good job. It arrived in the post this morning, so I'll let you know!
Tech Craft I received the case I linked to above. I can overclock to 2.100 GHz and the temp never goes above 60 degrees. It does draw a lot more power so I haven’t tried it connected to the iPad yet. It does work with a power bank I have though. Looking forward to hearing your experience with your new case. Thanks for your videos! Looks like the channel is gaining subscribers. Congratulations!!
Tech Craft I was watching on my work computer (ssssshhhhhhhhh) and it was running a mcafee scan which tends to slow down for things, so I was wondering if that was what was happening.
That's pretty cool! Also, just a small thing, I noticed that the audio becomes unsynchronized from the video at around 8:20, just to let you know. :)
