I don’t know about the voltage, maybe 1270mv is too high and the system is triggering a safety measure? Or maybe it’s a safety related to max power. Like I unlocked max power in Wattman but there is a function in the drivers that considers this isn’t normal and it needs to throttle the frequency to stock?

From what I’m reading in this thread this should all be a bug related to the newest drivers. I’m going to downgrade ASAP and share results.
Ok, 1270mv is too high. Recommended max voltage is 1218. Above that temperatures are increasing exponentially. And you risk degradation.
I think, your voltage damages the power usage somehow.
I have my stable around 1218mv, 2090mhz and power usage up to 380W. With junction temperatures around 100 and stable frequency around 2050.

I’m going to look into it but I think I can’t do much without more power usage, from what I understand.

Yes. I have +99% more power limit. And I wish it would be like 130%
Be carefull. One person here has killed his card at 1250mv(I think).

Thank you very much. I read on Reddit that 1250mv can provoke throttling and that it’s advised not to cross 1200 if possible. I’m starting to think that this isn’t a driver issue but a security trigger. I still will downgrade because the Power level at 50% is doing nothing.

I have two sweet spots: 2090 at 1218mv and 2080 at 1181mv.
There is miserable gain in performance going from 2080 to 2090, but large increase in hotspot temperatures for my water.
So I've stopped below 1200mv for 24/7

I noticed my PCIe bandwidth is down in the 9GB/s with drivers 19.7.1-19.9.1 while 19.5.2 is in the 13GB/s using the 3DMark PCIe bandwidth test. Anyone else notice this?

overclocking is worse i used to could pull 400w with older drivers

but i am just enjoying gaming atm

Radeon VII core overclocking is still broken with 19.9.2. Hopefully they fix it with 20

Very good news for me: I downgraded to 19.5.2 and now the max power limit is functioning. I did a quick test at 50% with 2000Mhz and 1210mV and it seems stable. Without raising power I was totally unable to achieve this frequency with this kind of voltage and I didn’t try lowering voltage nor increasing power limit yet. Very happy
