1800X overclocking performace

Hey guys, I just got my new Ryzen 7 1800X and was wondering if this a safe overclock: 4GHz with 1.375V? I have read up on a couple of sites that they used 1.4V to power a 4.1GHz overclock and only 1.3V to get a 4GHz overclock. I tried the latter settings, as  I dont want to push my CPU too hard at 4.1GHz, but I don't get a stable run with that in Cinebench. Now I know every CPU is different but is have a constant overclok near 1.4V safe? When I plug 1.4V into my BIOS it goes red, I assume that means that it is advised against.

 

Basically in that ramble I just want to know if 1.375V will be safe to run as my overclock.

Have you tried at first to keep the default voltage and increase the multiplier? Or you just decided to play with both multiplier and voltage?

The value you set in the BIOS might not be the actual voltage received by the CPU at all. Check with HWinfo on the vcore.

 

Ryzen is fine with 1.4V, but nothing more than that on air cooling.

Given the lack of difference between 4.1ghz and 4ghz I'd leave it at 4ghz at 1.3v since this is a fairly stable and safe setting.

 I did, but i couldn't get very far. I have tried to lower to CPU voltage as muchas I can.

Yeah I checked on CPU-Z and it says 1.8V. But as you said the BIOS input is a bit iffy, so that should be okay?

I know the difference i miniscule, that why I don't care about that extra 100MHz. But thanks anyways :)
