Help getting 2500K past 4.5ghz

post #1 of 7
Thread Starter 
I have had my 2500k fo a few weeks and OC'd to 4.5ghz no probs. Now i am trying to push it further as my test are mid 50s. I dont really want to go past 1.38 volts on the CPU so this might be my problem, but every time i prime blend, my 3rd core fails within a few mins.
Could this be a memory issue, i am running XMP profile at 1600 ,9,9,9,24, 1.65?

All my other voltages are on auto but the CPU. I tried altering them like the guide here states http://www.bit-tech.net/hardware/cpu...ore-i5-2500k/4

but no luck.
Please help?

Do you have PLL overvoltage enabled?

when overclocking I always start with the cpu then see what I can do with the ram, take ram back to stock including its timings and volts.

With 1.38v and llc enabled (llc reduces vdrop) take multi to 46 and stress with prime. if it fails then I see no other option but to increase vcore.

Im your opinion, would you say i am being to easy on the volts? My temps are fine, just worried about any harm too many volts may do?

Settled at 4.6Ghz with 1.36v. Anything above just requires a massive jump in volts, so this seems to be the sweet spot for this board.
