- Gigabyte Z390 Designare-OC
- RX Vega 64
- When I first built my hack, it worked great.
- A few months ago I had occasional crashes, but only when doing CG/rendering, where my Sapphire Vega 64 fan would spin to 100% for 10-20 seconds while my computer auto-rebooted.
- Last week I upgraded to Catalina and now it's crashing every hour or two, even when my computer is idle.
The only thing I've found that stops the crashes is unplugging my TV (HDMI cable) from the card.
I've updated the VBIOS, and my motherboard BIOS is up-to-date. I have a new 850W Seasonic Platinum PSU and have both 8pin power cables setup correctly (not daisy-chained). Temps seem fine.
Lastly, I ran Windows on the machine for a day without issues. So I think it's macOS specific.
Any other ideas? A bit desperate as graphics cards are insanely priced right now. TIA.
