[SOLVED] ASUS Prime-P Overclocking Voltage Controls

[webbs150]

Hello,

I recently used 1usmus's CTR to determine a safe overclock and voltage for my Ryzen 3600X CPU. However, I decided to try to implement the overclock in the BIOS instead of relying on post-boot software.

The ASUS BIOS are confusing to me. I changed the CPU clock speed and the CPU voltage (the latter to 1.25) and then I saved the settings and booted. A monitoring utility told me that the overclock worked but that the voltage was set at 1.1; when I tried to stress test, the computer shut off, and now it won't post. I assume I need to reset the CMOS battery and start again.

My question is: what other voltage controls do I need to adjust in the ASUS Prime-P BIOS to make sure that the manual overclock is fed a steady 1.25v?

Thanks!

Hey there,

Well not all chips can work at a desired speed with too low a voltage. Every chip is different, including yours. I'd start at 1.3v and a moderate increase in clockspeed. See if it posts. Then stress test with Prime95 small fft's. Wash, rinse, repeat.

You may have to reset BIOS/CMOS with a failed OC, most of the time, you should be able to get to BIOS and change settings, and just save and close to reboot again.

Once your stable, you can look at reducing vcore bit by bit, testing along the way, so you know it's stable.

Hi Keith,

Thanks for weighing in. I am certainly no expert about OCing, but I get the basics. I am fairly sure that 1.25v should be fine for the OC of 43.25 based off of the stress testing I have done to date, but I must have skipped over a setting in the many voltage options because it loaded into Windows with a voltage of just 1.1v and now won't return to BIOS on boot. To be clear, nothing is showing up at all when I turn on the computer - the lights of the MOBO are on, but no signal is passing through to the monitors. I am at work now, but am planning to try to reset the CMOS with the jumper pins later today and try again.

You can try using LLC to offset vdroop. Try LLC on the first 2 settings and see if the dip in voltage is less than before.

Watch with LLC though. At the higher levels it can overvolt the CPU.

CMOS reset will get system back up.
