Inconsistent crashes on Vega

This isn't my pic but anything works for GPU sag lol - I use a metal dowel rod I cut down and painted black to match

That wasn't it ,sadly. I've received further advice and apparently it may have to do with power spikes from vega which may overload the single rail on my PSU that I've connected the Vega to. I've got a Straight Power 11 600W btw. So I reconnected the GPU to the PSU in a way that both rails are used,(taking one 6+2 pcie connector from each pair of them)  to spread the load. Apparently that helped some people. Dunno if it fixed the issue yet, but the logic sounds promising.

Dammit was hoping the silence was things had gotten better.  Single and multi rail has to do with the 12v guts inside the PSU - though I get what you are saying and use that same nomenclature, and yes you NEED To pull from separate rails (cables) and not daisychain the power from 1 cable that has 2 connectors. Hopefully this fixes the problem!

I've had this exact same issue on my Vega 64. Symptoms match exactly. No matter what I tried, I couldn't get the card stable.

 

Ultimately, I returned the card, and the replacement worked flawlessly. As you are likely well outside the return period, you may have to resort to warranty service.

Found the issue btw. My Vega 56 Airboost just did not like the stock profile at all. All of my issues were resolved by tweaking it and I've since upgraded and sold my hardware. The buyer is not experiencing any issues either. A simple tweak to the fan curve fixed it. Props go to MSI for selling a card that does not run stably on stock settings. I wasn't the only one with those problems.
