Great stuff.
It wouldn't be surprising if the RP2350 gets officially certified to run at something above the max supported clock at launch (150MHz), though obviously nothing close to 800MHz. That happened to the RP2040[1], which at launch nominally supported 133MHz but now it's up to 200MHz (the SDK still defaults to 125MHz for compatibility, but getting 200MHz is as simple as toggling a config flag[2]).

Both the RP2040 and the RP2350 are amazing value these days with most other electronics increasing in price. Plus you can run FUZIX on them for the UNIX feel.
Mmh... I think that the LicheeRV Nano has kind of more value to it.
Around 20 bucks for the Wifi variant. 1GHz, 256MB RAM, USB OTG, GPIO and full Linux support while drawing less than 1W without any power optimizations and even supports < 15$ 2.8" LCDs out of the box.
And Rust can be compiled to be used with it...

Take a look at the `best-practise.md`.
It is also the base board of NanoKVM[1]
it might actually be better to cool from the bottom, since the pads probably conduct heat better than the chip package material
I bet if you designed a custom board it could do a little better
Interesting post. Curious what can I run on a RPi Pico 2 W since I recently got my hands on it.
Well, hope no one tries to deploy overlocked Raspberry Pi hardware in production... especially for kiosk style applications where they're in a metal box in the sun.
They're unstable enough at stock if taken outside an air conditioned room.
Haha — this was a fun day! It's honestly surprising how robust the RP2350 was under such extreme experimentation. Mike's write-up walks through pushing the core voltages far beyond stock limits and dry-ice cooling to see what the silicon could handle.
Credit where it's due: Mike is a wizard. He's been involved in some of our more adventurous tinkering, and his input on the more complex areas of our product software has been invaluable. Check out his GitHub for some really interesting projects: https://github.com/MichaelBell
Blatant plug: We have a wide range of boards based on the RP2350 for all sorts of projects! https://shop.pimoroni.com/collections/pico :-)
This some harmless stupid fun.
