edit: that being said, if you've had extensive experience using Kryonaut at temps above 80C and have not had any major problems, then perhaps that is not the issue.

Figures. I just saw a link to MorePowerTool earlier today and was thinking of using that instead (does basically the same thing).

Watch this space for future . . . uh . . . stuff! Yeah. That.

Hmm, I haven't done any power mods at all, just upped the power to the maximum 20%, and I'm seeing my card pull 384W at peak spike. Well, according to the Radeon driver overlay that is.

With the recent weather I dropped from 2100Mhz/1250Mhz w/ 1150mV +50% 1950Mhz/1250Mhz w/ 1065mV.

The Radeon VII when within the power limit will only fluctuate a few mhz not drop by 100's when within the power limit.

Edit: Did a quick test using Time Spy stress test.

Radeon VII w/ 1218mV @ 2050Mhz/1200Mhz with a PL of 20% runs between 1950-1990Mhz and stays around 290w average 1980Mhz

Radeon VII w/ 1218mV @ 2050Mhz/1200Mhz with a PL of 50% runs between 1997-2015Mhz and stays around 305w average 2011Mhz max GPU power seen was 346w in Overwatch.
Seems out cards are very different with mine defaulting to 1138-1143mv and becoming unstable around 1800MHz 1050mv when undervolting.
Even with 20-77% power use the card still hits the 373w limit and throttles at 1212mv although a little less so at 77%.
Power use is very spiky ~150-350w typically in all timespy tests.

Anyone having Core overclocking issues on Radeon VII with the 19.8.1 drivers.

For example setting say 2000MHz in Radeon Settings but in games the core gets stuck at 1600ish MHz. If I go into Radeon Overlay and set 2000Mhz while in game it will work like normal but upon restarting the game or launching a different game, back to 1600Mhz.

Leaving everything stock it boost like normal to 1800ish. Memory OCing is working like normal.

I did have. Ddu the driver and reinstalled and the problem was gone. But once crashing in a bench it would happen again. Then a simple reboot put the things back in place.

Yes, I reinstalled 19.7.5 and reported the issue yesterday.

I tried DDUing and the problem persist for me.

Thanks, reported as well. Was just hoping I wasn't the only one.

I have crashes when overclocking in drivers above 19.4.3. Peak consumption is more than 400w
I still have to check if newest drivers are ok.

Dunno never had Kryonaut drying out at me. But i also dont get temps above 80C Maybe in the past with the 1800x but again i dont remember Kryonaut was drying out. But i also never use tim longer then 6months.

Right now I can get 2050 MHz (1200 MHz RAM) stable with 1.229v. That's bench stable and game stable. The two seem to go hand-in-hand with this card. Max tjunct during anything is around 72C (usually it stays closer to 70C). I'm using +20% power limit.

@ssj92

Fluctuating clocks are normal for Radeon VII. It's impossible to get fixed clockspeed.

@majestynl

Did you use Kryonaut when putting that EK block on your card, by any chance?
Even with the clocks jumping from like 1400, 1600, to 1700 at stock clocks/voltage? They're not within 1700-1800 but all over the place.

In game they're around 1750 though.
