Voltage limit in Bios? x570 + 5900X

[jinxpad]

hey guys,


Was hoping to get a little help if possible, finally got my 5900x in the mail and got it installed. After soe tinkering around with Ryzen Master, I was wondering if there was a way to limit the peak voltage in the bios?

From what I understand, BIOS voltage ignores ryzen master voltage settings, and I haven't messed with PBO yet as it just looks like rocket science to me and I have no idea what settings to use/try with my motherboard.

But I wanna keep peak voltage down as if I just OC the old fashioned way by setting my multiplier to 46 and core voltage to 1.31 in BIOS, my temps skyrocket during cinebench (103 at one point O.O) and vcore goes past 1.4 blindingly fast.

So any advice or tips would be greatly apprecated.

I'm wondering this too with my Asus x570 / 5900x.

This won't be a popular opinion as this is an overclocking forum but here I go...

There is virtually no reason to manually overclock Ryzen. Stock/PBO is king. I've seen tangible gains but this has pushed power draw up substantially that it's a pyrrhic victory. I think it was Hardware Unboxed review where the 5950x was drawing an extra like 100w over stock...

I forget the exact steps but you need to do stuff like enabe PBO with max power limits and run prime95 small ftts and read what the SVI2 TFN sensor gives you in hwinfo. Whatever voltage that states is your "safe" voltage. I can tell you right off the bat that 1.3v would kill the chip.

If you really want performance gains on Ryzen look at memory tuning and nothing else. I've easily seen 10% improvement gains from slight tuning that virtually anyone can do compared to ensuring a stable and actually worthwhile cpu overclock.

Sure there are people that have been able to successfully undervolt their CPU and achieved great results but for how much effort has to be done for this for people inexperienced it's simply not worth it.

Yeah, would also recommend against overclocking unless you're specifically doing it just to get high numbers on a particular benchmark. You're not going to get a much better result than the default boost, and for some workloads will actually get *worse* results, while consuming more power. That's for high end ryzens. If you're on a lower end model this changes a bit because you don't have enough cores for all core OC to mess up your single core boost (and VV).

So, just Auto everything, xmp the RAM and go?

overclock the ram and FCLK if you feel more adventurous, then start on the timings if u can be bothered.

I just set everything to auto and - 0.1 on the core voltage, next to no difference in performance and I lost about 10 degrees off the top when gaming or running cpu benchmarks
