Jeez, it's running stable for me.My Pi4B 2GB, Rev 1.4 running Bookworm 64-Bit Lite (RetroPie):
arm_freq=2350
arm_freq_min=800
gpu_freq=940
I am guessing that it can't go much further beyond this, but I honestly haven't tried. Truthfully, I never thought that it could overclock this far. In terms of emulation performance, it is pretty close to being a Pi4.5 at this point.
Note that you do not need to set over-voltage or force-turbo anymore as the new firmware automatically scales the voltage from 0.85 to 1.10V based on core frequency. In fact, it is probably advisable that you don't set these values as running your Pi constantly at 1.10V is likely to contribute to a shortened life. I even go as far as to set my arm_freq_min to 800 so that when I let my Pi idle in the shell (which it spends 90% of its time doing) the frequency spikes from background processes are not as severe and the voltage stays at a constant 0.85V when not in use.
I am using the armour case with dual fans where the Pi is oriented vertically. Also, I substituted the stock thermal pad (which is probably just double-sided tape with no special thermal properties) with copper squares that I cut from sheet metal stuck together with PC thermal paste. The temps will go up to 60C if I leave it running cpuburn for a while but for my normal applications (e.g. dolphin-emu) the temps generally do not go much above 50C.
