How do you stabalise an OC?

post #1 of 3
Thread Starter 
Sorry for the n00b question. I'm on my 3rd OC and only really just starting to get the hang of it. At the moment my 2600k is bothering me. I have it in an Asus P8P67 WS revolution, 2x 4gb corsair vengeance, always in xmp. I've spent all day trying to get some decent results ( I won't mention the weekend) and I seem to be at a limit. In one direction (LLC above 50%) I begin to have too much heat on the board or something, because while it doesn't bsod, it gives out poor gflops in burntest, then become too hot/high on vcore to go higher than 4.8. It will run 9 run runs on max, with burntest, before bsod @ 4.9. The other way though, by keeping LLC down at 50% and pumping up the vcore, i can boot into 5.1 and run a few passes of burn test on high before it crashes. I still can't quite get anything stable above 4.8 though. From my understanding, if I can get it to boot into 5.1, I SHOULD be able to stabilise it at 5.0. Is that correct? I'm quite set on 4.9 and I seem so close, but I don't know where else to start fiddling...

I've noticed some people manually adjusting the Vsccio to assist RAM overclocks, does this have any effect on stock RAM or will I just be adding heat?

Also I've seen people post PLL of as high as 1.89, I thought that 1.79 was the absolute max?

Lastly, what was the final conclusion on BLCK adjustments? This isn't a 24/7 machine but it will be used several times a week. If it helps with stability or performance then I'm keen, but some say not to touch it, Asus said somewhere that +/- about 3 was ok (from memory)...

You should not touch the BLCK unless you are moving the actual strap, touching the BLCK without them also moves the PCI-E frequency which puts your cards(in PCI-E slots at risk of falling out of sync or frying. Also Gflops in Intel Burntest are quite irrelevant to performance, you shold be using Prime95 to test OC stability, not Intel Burntest, the only thing it really does is produce a lot of heat(my i7-3820 was 10C cooler in P95 then in Intel Burntest AVX). I found the LLC at 75% kept the power flow without vDroop. Adding voltage to the PLL does allow you to keep the vCore lower but as for the safety of it being at 1.89v I have no experience. Unfortunately I am unable to answer all of your questions, but I hope this little bit helps.

What memory frequency are you currently running?

What is your current QPI/VTT voltage?

You shouldn't be tweaking BCLK IMHO - leave it at the stock Auto or manually set to 100.

What is your current CPU voltage?

What is your CPU cooling solution?
