I got my processor in December of last year and tested its performance mainly using Cinebench R15. Without overclocking it scored 932 cb, when i put it at 4.6Ghz at 1.325v it got a score of 996. All of this was fine for a while and then i noticed instability in a game I played so I turned it back to stock speeds by resetting to default. Fast forward to now and I decided to try overclocking again. I ran an initial test and I see that my CPU is now scoring 813 cb in Cinebench, almost 200 points lower. I use XMP for my memory and have the CPU cooled using a Corsair h100i v2. I still notice instability in more than 3 games no matter what I do. I've seen no thermal throttling, so now I am at a loss of what to do and am in need of more outside help...
