My system is the following:
AMD 1600 processor (AIO cooler)
Asus Prime B350 mobo
16 GB FlareX ram
Windows 10 64bit on a Kingston ssd
EVGA 650W powersupply
Dual Curved Samsung 27" 1080p displays w/ freesync
The issue is that i swapped out my Gigabyte 970 Extreme for the vega 64. I Upon boot, everything seemed fine until I tried to play Fallout76. Framerates had to be in 10-15 range. Laggy as heck. I uninstalled all drivers, Nvidia and AMD and then reinstalled the latest AMD drivers. I then had the screen going black and then just coming on and turning off. I rebooted and checked my graphics speed. I was getting around 50mghz on the clock speed, I kid not.
So, is this related to the fact that I could use a bigger power supply? I have nothing overclocked at the moment, and I could run my cpu @ 3.9ghz stable with the 970 oc'd and run cool and stable... no power issues. Or is it something else? I saw a thread about the heat sink coming loose on the gpu. How do I check that without voiding my warranty? My temps seemed to be fine... Around 40c at idle.
