2.147 GHz overclock? It seems like someone got lucky and won the silicon lottery. That and a good cooling system.

[@BillyNoMates1974]

interesting video. great work. keep it up. I bet there is a golden gem setting out that that just hasnt been found yet.

[@Winnetou17]

Interesting results. Regarding the 1900 MHz and 2147 MHz, those seem to be not actually running at that. I remember Gamers Nexus saying multiple times that doing an OC and booting isn't enough, you have to validate that with the benchmark results. Because if it's not better, then it's not also actually running at a higher frequency. If I were to guess, maybe the Pi simply boosts to 1900 or 2147 and immediately scales down. Is there any way to plot the frequencies while running the benchmark ? Anyway, nice 1450 MHz overclock!

[@leepspvideo]

I still can’t work out why 2147 performs better than 1900 and 1300 but not as good as 1450.

[@sail4life]

@@leepspvideo could be ram bus timing or something like that. clocks that aren't in sync can suddenly halve the effective speed.

[@plkh9602]

@@leepspvideo The best I got from a BCM2837 (on all 4 A53) was about 1550 I doubt the 2147 as seen on Pi 4s is reported correctly 😅

Thanks for sharing !

[@breevwhyman2985]

great video.........giving "Pi zero 2 w" owners a free boost........... thx V

[@rossq9432]

It sounds to me like it is thermal throttling at the higher frequencies, if you upgrade the cooling you might be able to push it further. It is always important to monitor temps when doing any overclocking.

[@leepspvideo]

I don’t think it ever reached 50

[@foobarbarfoo2377]

Good. It may be worth giving results based on the: 1. connected devices (USB, ..) / 2. type of processing (data read/copy, CPU, ..) / 3. the power source (max freq. will obviously be capped when running the Pi on-battery, ..) / 4. type of cooling (fans, passive, hybrid, ..)

[@MrJaz8088]

Any powered hub should work, as your adding the extra power to cover

[@BillyNoMates1974]

Ive been having a play on my Pi zero 2w running OpenWeb Rx Plus and found some strange oddity at an overclock of 1200 and Over_voltage of 4. I get loads of RF bleed over on some frequencies but if I back the overclock back to 1100 and an Over_Volt of 4, it works fine. The overclock of 2147 didnt boot and an overclock of 1400 did boot but was unstable. I guess I will stick with an overclock of 1100 and over volt of 4 as this seems stable for me.

[@germany1809]

Ok, I am not getting it. I use the settings from minute 00:27 and pushed the frequency to 2,6 GHz. With over voltage 11 it's not getting as near as warm as with lower voltage. How does this relate? Am I living dangerous or why can I push so much?

[@leepspvideo]

It’s definitely mis reporting try the test to see if it’s faster.

[@germany1809]

@@leepspvideo I put in 3 Ghz now. Is there a way to measure the real time clock speed?

why do you over clock a pi ??? what do you want to do with the overclock ?????

[@leepspvideo]

To increase performance. An operating system with a graphical user interface runs better. Games run faster and smoother.

[@kekkokan9273]

A couple o Zeros 2w arrived just today, I will try to cook one :)

[@ndupontnet]

I somehow managed to get down to 17.30s at 1500 with overvolt 8. It worked twice in a row, but got kernel panic at the the 3rd time. I did overclock core_freq and ram as well.

[@ndupontnet]

Stable 17.97s with this config : arm_freq=1450 core_freq=566 over_voltage=8 sdram_freq=566 over_voltage_sdram=2

[@splatink]

Seems like 2147 is just ignored and it runs at clock speeds or something like that.

[@Jcarlier50]

great video ... which usb hub do you recommend (powered or not) and which one you use thanks

[@leepspvideo]

I use an otg hub with the official pi 4 usb c adapter. I use a usb c to micro adapter. Links in the description

[@Mlarsen1985]

Does it have anything to do with the Ondemand Governor? or does the manual overclock settings bypass this

[@dogshome7110]

Reminds me of overclocking Athlon 2400 to 3200. Depending on timings, some frequencies worked and others didn't i.e. 3350 would run, 3250 wouldn't. 3200 was stable 'most' of the time. If you are on this kind of limit, back off a long way though as the little bugs multiply and scramble your OS install eventually. I ended up around 3000 as I got fed up with Windows file corruption, even with a huge cooler and low temperatures. Humongous power supplies and good motherboard design also have an effect up at the edge. I run my Xeon 2689 bog stock. No issues even with a Chinese motherboard rework and second user CPU. It will overclock with the Russian BIOS I have, but it's not worth it. The Xeon won't let you go crazy on package watts anyhoo. Interesting viewing. Poor little pi :-)

[@williamlegotyler1825]

Wow,i wasnt thinking the pi zero 2w could be intercooler that much!,in the next video can you overclock the pi zero 2w to 1.4 ghz,overvoltage 6,and swap size to 2000 mb,and after you optimized the pi zero can you try to watch a youtube video at 720p,so we can see the performances? Thanks

[@dogshome7110]

My Chuwi HI9 just died (touch panel gone) Brilliant, cheap machine with no bugs. Very high res 4K for an 8" tablet. Teclast replacement has a faster CPU, is cheaper, but screen is only just over 1080 and one or two minor bugs. Good enough at this size though and 1/3 the price of name brands. 3-5 years I get out of a cheap chinese phone or tablet. Usually killed by numerous drops or physical things eventually.

Wasnt it only 2k? Or was there a 4k model

[@elnasty555]

Another interesting video sir. I want a modern pi-zero. You said in one video to communicate via a recent video so I found no difference using retropie roms from a usb2 hd to using a usb3 ssd. This is on a rpi400 booting twisteros from a usb3 sata ssd but applies to all rpi. HD sata drives are cheaper for capacity than ssd. Would using a hd be better for storing roms? HD take 10X the power than a ssd. USB3 sata for twisteros boot is faster than sd card or usb stick but retropie from usb3 ssd is no faster in loading... zx spectrum file takes minutes when emulation station starts.

[@elnasty555]

PS. I've been trying n64 starfox and fzero and they are different to snes. Gobsmacked at the display and performance. Glad I got a rpi400 and all possible with your sites help. 3D earthworm jim and a 3D mario game. Very impressed.

[@leepspvideo]

I often use a 2.5” HDD for Retropie roms. The usb 2 socket uses less power. I find usb 2 more reliable with mechanical drives. DeskPi lite Raspberry Pi 4 case.

[@elnasty555]

@@leepspvideo I like the alloy rpi4 cases you showcase. I have a rpi3 in a flirk case but rpi3 doesn't heat up like rpi4 it seems. HD drives seem fine for running retropie roms with retropie as an app on twisteros on a usb3 ssd. You show retropie can run from a HD. Some HD need a usb to sata with either 2 usb leads or a socket for a 12V dc supply.

[@elnasty555]

I have bought sata ssd and used a usb caddy or adaptor and the drive doesn't show in win 10. I've had to return it and the seller says checked and showing. I received a 250G sata usb a few days ago and it did not show as a drive. I used free easus partition manager and it showed the drive as disk2 formatted with ntfs so pressed create and reformatted as exfat as drive F: It works. Ever had that problem of windows not seeing a drive?

[@vikingofengland]

You need to repeat the iffy results again, maybe three times, to see if it was just a rouge run with some background processes consuming CPU.

[@yllib2012]

You can obviously overclock the CPU but you can't do anything abought the tiny 512MB RAM. It still has plenty of uses for projects and retro emulation. Tiny it is but by the time you add a USB hub to the equation, the footprint becomes larger than some Mini-PCs with MUCH more power and 16X the RAM of the Pi Zero 2.

[@leepspvideo]

My MeLe Mini PC is great! Amazing Silent Ultra Mini PC. MeLe Quieter2Q. Plus Steam Proton Test. kzbin.info/www/bejne/iJndhqJso9WiipY Big difference in the price though

[@HiltonT69]

I'm waiting for something like the MeLe Quieter 2 but based on the new N6005 Intel Pentium CPU which should be a much better performer. Though that new Beelink GR9 is impressive with its dual NVMe, SATA SSD and 64 GB. But, again if they can take the newer Gen Ryzens...

Cool video, is the fan connected to the GPIO pins? Doesn't look like it. My zero 2w runs idle around 42c with a heatsink and at stock speeds. Stable at 1300 and 4 over voltage but performance wise not noticeable. Also temp rises to 70c when running Chromium.

[@PlayingItWrong]

You could build that pi zero into a mug mat, have it run folding at home and keep your coffee warm while curing cancer. The fan shim sort of hooks onto the gpio pins.
