I've just noticed @TheVic1600 that you have a 500w PSU, that could be a limiting factor for you. A PSU is most efficient with a 50% load, max it out and that drops quite a bit, add to that your RX570 under load is going to take at least about 200w and the rest of the system probably another 150-200w combined you're starting to push the limits of that PSU which probably is going to influence your maximum stable OCs and required voltage. If thats something you think you might explore in the future then a good Bronze rated unit such as the Corsair 750w CXM in the UK at least is only £60, with Gold rated units often only being slightly more, the Corsair RMi 750w for example is £75, and a rather nice PSU at that I'd certainly consider picking one up if I needed something to replace my 1Kw Supernova. RIOTORO also make excellent PSUs, the Enigma 750w G2 in particular looks very interesting.

Decided to put this to the test as I got a great deal on a Corsair RM650x 2018 revision. Was eyeing it for some weeks after I saw tests of it showing it having very low voltage ripple on the 12v rail. Was hoping it would get rid of the extremely hot cap situation on my RX 570's VRM but it didn't. Still, I'm now able to hit 1350mhz at 1056mv(1068mv with the old 500W Thermaltake GX1) and I've noticed that the GPU Core Voltage is a lot more stable under load, like it doesn't jump around as often as it used to. So you were definitely right about the required voltage bit. Also, maybe this is placebo, but I feel like most games run a bit smoother, like I'm noticing way fewer of those brief freezes. Maybe the GPU getting cleaner power has improved its stability.

@TheVic1600 the hot cap problem is just where you have an under specced VRM sadly, VRMs get very hot anyway but good ones on a card like a 570 won't go over about 80c. You aren't imagining games being smoother either, high ripple on the 12v rail leads to power spikes and fluctuations that do impact hardware stability and longevity. Bad PSUs have killed many hardware due to that sort of thing ;) I thought your old PSU was limiting you in some ways nice to see you have that core voltage as low as possible now to help that VRM out.

Ok @ket . Is it possible to make all the necessary changes and provide me a copy of my bios using .975 Vddci please. Also I would like a higher max voltage limit to---> 1.3 not to use it for 24hour but just to try for benching.
I hope I am not requesting too much. I can reupload a clean copy if needed or you can use the previous one.


Also any chance if it's possible to raise vrm switching frequency to 1000khz?

If I get a chance I'll do this, I messed with switching frequency through software only I wouldn't advise whacking it right up to max that's just as bad as having it set too low, somewhere between 625-750 will likely be optimal. As for how to change it via vBIOS, I have no idea. @karmic_koala might do.
