Did you lap the heatsink? I used 400/800/2000 grit wetsand and a machinists square to get it flat. These heatsinks are horribly warped from the manufacturing process, hence the graphite pad.
I did not, I just tried 2025/1200 @1150mv and got 9679 on timespy with a gpu score of 9735. So for me I needed a bit more volts.
Trying to get a complete run with 2120/1200 but I'm up at 1200mv and still it crashes the run.so I will just wait for the water block I guess.

You posted back a few pages a picture of some green graphic glitches on the screen I've just had that myself for the first time, and then it went away, now I am worried. Can you tell me what caused yours and how you got rid of it

I didn't I sent it back & they returned it saying there's nothing wrong with.

This is an interesting one and reinforces what I was talking about yesterday.

"Back in 2017, EK released a report which claimed that their RX Vega 64 offered a 9% performance boost and a 4% reduction in power draw by trading AMD's reference blower for the company's full-cover water block. Perhaps the Radeon VII would see similar benefits when liquid cooled. I guess we will just have to wait and see."
Source: https://www.overclock3d.net/news/gpu_displays/ek_teases_their_radeon_vii_full_cover_water_block/1

It isn't very clear but its saying out of the box on water it holds higher clocks and manages to save 4% on power and gain 9% more performance. That's all from the block cutting the temps in half!

Found the table of figures:

I've noticed several people, Including myself, Complain of their R7 becoming highly unstable when the junction temp gets to 110'c at stock clocks/volts/fan curve, Which is a stupid temp, I don't think this is down to a fault with the card itself but as others have pointed out the heat spreader does not make proper contact, I had a similar problem years ago with a 290X which was fixed by putting a 3rd party cooler onto it as the reference cooler was not making proper contact.

Got my Sapphire R7 yesterday - very pleased with it but crikey it's loud!

Make sure you flash the latest BIOS and have the latest drivers. Made a decent difference for me.

Only started playing a bit but managed 1900mhz with a slight undervolt at 1050mv so far. Got 950mv UV at stock 1800mhz which seemed ok.

Junction temperatures get quite high though so might try loosening the screws on the bracket and retightening which was mentioned a few pages back.

Going to be interesting to see what bios the 2nd wave of Sapphire cards have shipped on....?

Mine arrived yesterday (so second batch?) it had the 105 BIOS so I updated to 106

So on the older bios too:

GPU Device Id: 0x1002 0x66AF 113-D3600200-105
BIOS Build date: 2019-01-16 17:56:00
https://www.techpowerup.com/vgabios/208116/amd-radeonvii-16384-190116

New one you now have then:
GPU Device Id: 0x1002 0x66AF 113-D3600200-106
BIOS Build date: 2019-02-11 14:18:00
https://www.techpowerup.com/vgabios/208738/amd-radeonvii-16384-190211

I wonder how long its going to be before the cards ship with bios 106!? And if other brands of the cards are shipping on 106 yet?

I think i have to do that with the screws as the junction temp is far too easy to hit and it makes my whole pc crash if it goes above 110
