Depends on the workload. If I ran something like 3DMark Icestorm then yes. If I ran Superposition then no.

@majestynl

Okay then it seems your TIM drying out wasn't the culprit.

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

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!

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

Just had a go at using Igor's MorePowerTool to raise PL to +50%. Wow! I had no idea it would stabilize my card so well at lower voltages. Now I'm hitting 2100 MHz at 1.187V with hotspot temps @ 70C running Superposition. Not great compared to some of the cards in here, but definitely better than what I had before. Not even done tuning this thing yet.

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

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.

Try 19.4.3 most working for overclocking

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

I am using 19.8.1, yes. I have not had that problem. Fortunately.

Unfortunately, stability on my card past 2100 MHz is difficult to obtain, even with MorePowerTool. 2100 MHz requires maybe 1190mV, but 2150 requires over 1240 mV. It runs, and it stays below 80C hotspot (and power usage is only 325W peak according to Wattman), but still. Not the best of the lot. Maybe I should be messing with some of the current limits on the card?

For now I'm messing with RAM speeds above 1200 MHz. 1225 MHz seems stable.

Also, has anyone here tried GFXBench on Radeon VII? I find it to be incredibly demanding in terms of temperatures and stability, compared to Superposition which is what I normally use. I find it difficult to stabilize GFXBench 1440p offscreen at anything above 2000 MHz.

I remember when I first got the card it would hit similar power usage numbers like yours. So I looked into the issue. I was using 19.7.5 that net the consistent frequency and lower power usage. I uninstalled it and reinstalled 19.5.2 and my frequency and power is similar to yours also. I noticed I could no longer hit 34000 FireStrike scores with driver 19.7.5 but I could hit around 33300+ turns out for some odd reason DirectX 11 titles run 30Mhz lower with this driver compared to 19.5.2.

I'm going to stick to 19.5.2 and see if I can test it further or if anyone else wants to.

Edit: Probably happened with 19.7.1
