Yeah that did throw me when I first installed the card and brought up GPU-Z. I'd forgotten about that!

Hmm, played with my new aio Vega from sapphire for a whole day yesterday and sadly it seems to be crashing after a few minutes of full load. I can run full firestrike at times or crash. Same in Witcher 3 or Destiny 2 beta. No artifacts or anything strange, then sudden black screen or dark gray with vertical darker strips and reboot few seconds later. No problems in less demanding games like WoW, unless I stress it up by for example setting 4k virtual resolution (so the GPU goes to over 95% use).
750W psu, wall usage only a bit above 500W, so way below PSU limits. Newest drivers. Fun fact, left it mining (Merito) for the night to see how that works, zero issues... Also run full firestrike stability test and no issues there either. Very confusing!

Try my HBM "memory voltage" tweak via Wattman and see if it makes a difference.
Yeah, I've tried that (1050) in the driver itself. But not sure if that took. I'll need to spend more time with proper monitoring of voltages and stressing it up. For now I just figured out that using bios switch on the card doesn't help and adjusting power settings also didn't help unless memory also throttled to 800mhz (slower BIOS and power saving mode), as then it seemed to be stable.
I assume newest wattman for adjustments and hwinfo for monitoring?

Apologies, I forgot to put my name in the pic because I snapped it quick for a reddit post lol
Had this actually day 1 but been away, the DK04X from Lian Li, the mouse and the mousemat are new too
Sexy? Even sexier when I watercool it!

To get on the Roll of Honour all you have to do is post a pic with your user name on it of your Vega 64.
Sad to say, but welcome to the 'club'.
I have exactly the same issue as you do with my Vega 64 LC. I can play The Witcher 3 by limiting it to 60fps in the settings, but yeah, gotta be careful not to push it too hard.
It's super weird though, because if I play DOOM with VSR to 4K, all maxed out, I can play just fine and don't have any crashes (I didn't try it for thát long, but it didn't instantly crash like The Witcher 3 does).
Anyway, good luck on your RMA!
Not giving up yet, as I don't have other GPU to use at the moment (Ryzen doesn't have integrated one either). For now poked sapphire Support about it. They might have some ideas... Or not.
I wouldn't want to be forced to buy Nvidia (the only available with sensible noise at the moment) just because my Vega isn't available to be swapped fast in RMA :/ frankly, I'm thinking it's more of the drivers/bios issue then hardware but we'll see.

Yeah, I hope it's a bios/driver thing too, there are TONS of Vega64 LC people having this issue, it's just silly right now.
Anyway, I'll also poke the Sapphire support, the more people bringing it to their attention the better I think.

Some Destiny 2 gameplay from last night. 64 performing pretty good to be honest.

Are you seeing stable clock speed, I have 1635 set in wattman and on the graphs it shows 1612 to 1623 I have 1150v in stage 6 and +20% power limit. It now always sits happily in stage 6 constantly because the temperature is under control. I didn't want to push the power too much until the drivers improve and I am happy with the performance. I also don't want to end up like it seems many of the LC owners are having.
I also have an EK block fitted max temp is 42 after 2 hours of gameplay which is very nice.

Well, according to Sapphire support liquid Vega should be working just fine on stock clocks with my PSU. Black screen etc. described usually means defective card. But that would be all lots of these out there, then. :/
For now Sapphire advices RMA with retailer and hope for the best... I'll try all the other steps first, as RMA for me pretty much means going Nvidia in this case.

Yes I've got 1750mhz set but in games it doesn't really get there for some reason, whereas benching seems fine. It kinda hovers around 1690 to 1710 obviously heat isn't throttling it as my max temps are also around 39c to 41c.

I need a new power brick... since it is not modular (7 years old) and my new vega 64 kick his assNice, only other thing that spring to mind is cable management.
750 Corsair 80+ bronze is the limit for VEGA
Happy to report on my end that I found another Vega 64 Liquid Edition (MSI) in stock from another retailer, delivery scheduled for tomorrow
My "black screen" Sapphire has been sent back to OC UK for full refund this morning, really gutted a got dodgy one in the first place. My usual luck I guess...
