1700X (was at 3.8Ghz @ 1.35V)
Asrock Taichi X370
32GB (2x16GB) Corsair DDR4 Vengeance LPX Black (was at 2800mhz CL14)
Seasonic Platinum 660w
If anything it was likely to be the RAM TBH, I had it at 2666mhz CL14 for a long time and changed it to 2800mhz a few months ago after a BIOS update and it had seemed solid until now.
Next step might put the CPU OC back and do some more gaming
Was just worried it was the GPU as that was the only change.
Was previously running 290's in crossfire that almost maxed out the PSU without any issue, the Vega VII is quite tame in comparison, not going much over 450w total system power.
