Had recent screen flicker and cpu frequency spike, is this related to ram? My graphics card is new and a replacement for the previous faulty one. I'm sure that's fine. The distortions and flickers don't particularly appear as if it's a graphics issue. Worth noting I used the ram in my old rig, xms3 corsair 4 x 2gb, I did overclock it once but stopped that. Also noticed the modules get very hot.
