Raspberry pi overclock

[PCTechBoi]

Is it possible/safe to overvolt my rpi4 to 7 volts rather than 6?

If you're talking of the input, no. And why? It wouldn't achieve anything anyway, nothing uses the 5V input directly.

I want to overclock more because 6 volts is what I’m at and I’m up to like 2300 MHz so far on the cpu and 825 MHz on the gpu, it crashes when I go higher and do anything intensive which means I don’t have enough volts.

i think the OP is talking about the over_voltage setting.

Pi4 I believe starts at 1.2v with over_voltage in 0.025v increments, which would make a power level of 7 = 1.37v.

 

I can't find any official specs but the drop off point is usually at 6 or 1.35v and is usually considered the max safe value.

Around 2300 MHz is the max Value I have seen for a Pi 4 and only a handful can run stable at that speed. Your probably just hitting the wall and need to step down the overclock.

If you're talking of the value you set for over_voltage then that's not volts, it's "steps of 0.025V"

You can set higher values than 6 but it will set a permanent "warranty void" bit. Of course you'll want good cooling.

I can run 2300 MHz stable while doing intense tasks for long periods of time

I believe you're referring to the over_voltage settings...Do NOT go over 6. Just trust me, the minimal gains you may see aren't worth the risk.
