**The PROBLEM*** I did finally get it to boot at 4.2 ghz but now it only sees one stick of ram. do I switch back and try manually with another program to go for a lower boost? or does this indicate the ram stick is either dying or on the way out? so I have been having trouble running pubg. my older system ran it fine until one of their updates. Since then I have upgraded to windows 10, added a wd ssd, and a 1070 its choppy in the game a lot. trying to tweak settings has not helped so far. I decided to try overclocing the cpu with the msi oc genie 2 and I had some issues booting which I thought goes back to the windows 1083 update that thousands have had an issue with. do I bother with memtest or prime? almost pulled the trigger on an all new setup but then decided to just get a newer psu to see if that helps and if not, probably build it new from there. unless someone has a better idea. system specs 16 gigs dd3 core i5 3570k win 10 64 wd ssd blue msi z77a-g45 gaming mobo asus xonar sound card. broadstream nic think its a corsair 750 psu not sure if any of the other devices matter.
