Overclocking Ryzen 3700x

sparkski · September 13, 2019

Hi there,

I've been using Ryzen Master to overclock my processor, and I think that I've found the settings that work best for me. However, overclocking is new to me, and I want to make sure I don't mess anything up. My CPU has been working fine at 4.2 GHz and with 1.315 V.

First off, is the CPU Vcore setting the maximum voltage the CPU gets or does it lock it at that value?

In my BIOS (Gigabyte X570 Gaming X), I can't edit the CPU Frequency, only the CPU Clock Ratio. If I enter 42, will this translate to 4.2 GHz? And again, will this be the maximum value or will it be locked there?

Also, I'm not sure if I want PBO enabled, but I've heard something about disabling it voiding your warranty? If this isn't the case, is Core Performance Boost what I would turn off or does PBO have a setting of its own?

Thanks for any help

in the bios, it's the idle voltage of the CPU (assuming minimal loadline calibration). Under load it will drop lower, which needs adjusting loadline calibration to counteract. Too much LLC and it will overshoot. LLC itself comes with the side effect of voltage spikes, so dont use so much LLC that leads to overshoot.

Yes. CPU frequency is "base clock" (default 100MHz) * "clock ratio".

PBO and auto OC are both part of the automatic OC tool (BS) and get overridden by manually set clock ratio. Prone to using high voltages that leads to high temperatures tho so I myself wont use it.
