Quick question folks, i'm using a FX-8350 and i'm primarly looking for bettter in-game performance when overclocking it.

I understand that a blend test in Prime95 will put a lot of load on your ram compared to small fft's.

Which test should i use to check stability with when it comes to games liike BF4, Crysis and Starcraft II?

This guy who made a easy to follow overclocking guide uses small fft's:

So which test to use? My CPU has runned fine in small fft's but cores start to fail with a blend test.

Thanks in advance!

if you're testing for game stability, i wouldn't use P95 at all, i'd test with AIDA64 with only the FPU test checked (this is a extremely stressful test and i don't recommend you run it for longer than 20m or so).

for games like BF4, even if you can pass 12 hours of P95, it can still be unstable for that game. BF4 stresses all of your PC's components at the same time, while P95 is limited to CPU and RAM.

if you're looking to be able to stress test all of your components together at the same time, i'd recommend AIDA64.

Thanks for your answer, but when checking for CPU/RAM stability, should i be using a blend test? It seems obvious that CPU overclocks will affect your ram as well since my blend test fails compared to small fft's which doesn't fail.

If U are oc less then 4.6GHz do not use "manual voltage" (constant voltage) use offset mode. Do not turn off: C1E, SVM, Core C6 State HPC and APM... or your PC will freeze in idle state. If U oc more then 4.6GHz it`s hard to do this in offset mode.

Do not run Prime95, OCCT more then 1-2h, If something is unstable it will result a error in 30 minut max.

I realize this is an older thread, but I wanted to interject for the benefit of anybody else who happens to come along and read this thread. The above statement is entirely false and should be ignored completely. Prime95 may take up to 16.5 hours to run all of the various length FFT's. Some cpu's struggle with specific length FFT's more than they do with others so it's important to allow them all to run. Beyond that, the remaining recommended 24hrs probably isn't 100% necessary unless you run mission critical or scientific applications where micro-errors could be catastophic, but it certainly wouldn't hurt to finish out the 24hrs or longer just to be safe either.
