I own a PowerColor Vega 64 Liquid Cooled and for the most part, it runs okay.
Only recently have I overclocked my monitor to 75hz, allowing me to get the card to run much faster and in turn forcing it to hit 100% usage. This is a problem as after around 5 - 15 minutes under this load, my screen will go black for 15 seconds and the game along with the AMD Radeon software crashes. The temps never seem to go over 50c so I don't understand what is happening?
Anyone have ideas. I tried emailing NewEgg (the supplier) but they couldn't help as its been 6 months since I got the card and then Powercolor but they never respond to emails.
