CPU Overclock and stuttering

post #1 of 4
Thread Starter 
Ever since I OC my i5-3570k to 4.2 Ghz, which is in no way overboard, I've observed some very minor stuttering / microstuttering when playing some games (Crysis 2).

I am pretty sure my GPU OC is stable as I haven't encounter this problem before.

Bear in mind that I've done stability testing with no BSOD or anything, and 4.2 Ghz should be doable on this CPU. How likely do you think the stuttering is the result of an unstable CPU OC?

My spec:

i5-3570k
HD 7950
8 GB RAM
Win. 8

have u tried just running the game @ stock clocks and checked to see if the problem persisted?

it's hard to say what the cause is, the stress tests can tell you that your stable to a certain degree but, it's still possible for instability to occur in games.

mr1hm is spot on, however I don't think that small of a CPU overclock is the issue.

Instead, I think that your GPU overclock is causing this, can you trying running your GPU at stock clock to see if the issue goes away?

It could also be simply AMD Catalyst driver issues, try using the newest beta.

I've been running into a similar problem with CS:GO, I can run stress tests all day and be fine because my CPU voltage is it a higher/stabler voltage, while i'm gaming my chip is constantly going from x16 to x100, every once in a while when the CPU boosts up its speed, the voltage isn't there to allow it to causing the game to stugger or even crash. There's even been a few instances of BSOD due to low CPU voltage. I'd say if you've narrowed the problem down to your CPU causing the problem, adjust your vdroop so they CPU Voltage doesn't droop (lower) under load. You can also try raising your voltages a hair.
