OCing working great for me on 19.7.5. I just sort of want to get an idea of if my OCing issues are widespread on Radeon VII. I know one other user reported they had similar issues on 19.8.1

Not even done tuning this thing yet.
Are you running Driver 19.8.1? I can't seem to get the card to OC correctly of 18.9.1, If is OC the core at all, it gets stuck in the 1600Mhz range.

Anyone have experience? Apparently the pad decreases junction by 10 degrees (according to claims on Reddit).

drmrlordx I definitely would have gotten a Watercool block for Radeon VII had they made one. Alas.

@majestynl

Okay then it seems your TIM drying out wasn't the culprit.
No def not, cause the both blocks where installed max few days!
Switched now to a 2080ti because the seller didnt had any R7 left Currently a Heatkiller Block installed! Must say.. never going back to EK. This block is a beast and quality feels also much better!

In game they're around 1750 though.

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?

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.
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.
