So, after ocing my fx6300to 4.1ghz at 1.375 vcore, i decided to do a stability check. Well after almost an hour of testing worker 5 fails, idk if the others will fail or not in the next 24hrs, i will update. What should i do, keep the oc, change vcore, change ghz? What do u think guys ? Thanks for the support

If you are unlucky enough to have a chip that doesn't like higher voltages, or a mobo that's unstable at high wattages, your only real choice is to lower the oc to 4.0. I'd try manual 1.5v first though as most FX6300 seem to do 4.8Ghz there. "Auto" setting is frequently unpredictable.

I assume your RAM timings are relaxed and not set too fast while you are trying to find the max CPU oc, right? After all large FFTs are primarily used to test RAM.

I'll admit I only use Prime95 for 24h as a final stability check because it takes too long to use to determine an oc. For that I use 5 passes of IntelBurnTest, which is a handy shell for Linpack, and relatively quick.

Hi Akuman1:)

If a worker fails then P95 has halted and probably no indication of why.
P95 is a harsh tester and will push your CPU to the max.
OCing method is to stress test the system at stock frequency with default settings to establish a baseline for OCing.
Download AIDA64 (free addition with self extracting .exe) then run the stress tester and check boxes for CPU,FPU and Cache. You can also test your other subsystems independently.
If you want your results analysed then use IMIGUR as a link here and Bios tweaks will be recommended. Take screenshots at the 10min mark and stop the test if temps go above 70-75C.
Analysis will be based on temperatures and Rail voltages during the test under load.

I'm guessing its not stable so, here's the problem, whenever I go a bit higher in voltage, BSOD happens computer crashes. At around 1.425 voltage. As well for the other cores they haven't failed at all.

Thanks for the reply, but the CPU never makes it's mind about its voltage, a few days ago, at stock it was 1.425 volts, and yesterday it was 1.325. And whenever I OC at these voltages, PC crashes, BSOD happens. So I raised it a bit.

I got it running at 4.1ghz at 1.39 volts stable in prime95 for 24 hours, pretty stable. But thanks for the help anyways. There's still another problem though, but there's another thread for that, if any of you want to help out. Here's the link: link for thread
