General discussion • [Raspberry Pi 5] Experience with undervolting?

Hello everyone,

I reduced the voltage of my Raspberry Pi 5 by 0.075V (Load: from 0.8986V to 0.8208V) and reduced the clock speed from 1.5GHz to 1GHz for idle without having any problems with stress --cpu 4 and GeekBench 6.4.0!

Questions:
How little voltage did your Pi5 manage?
What do I do if I reduce the voltage even further and then my Pi5 no longer starts?

Clock speed (Idle):
Before: 1.5GHz
After: 1GHz
Voltage (Load):
Before: 0.8986V
After: 0.8208V

GeekBench results:
[6.3.0]Before (0.8986V): https://browser.geekbench.com/v6/cpu/9919608
[6.4.0]After (0.8208V): https://browser.geekbench.com/v6/cpu/10225976

I would be happy to hear about your experiences and tips!

Thanks!
