Overclocking sandybridge, bios questions

post #1 of 3
Thread Starter 
I am wondering what should I do with Internal PLL overvoltage? It's disabled by default and I think i heard enabling could be dangerous is this true? and is this option neccesary?

Other question Is there a difference between offset voltage to cpu core or the additional turbo voltage setting. Both seem to do the same to me, and just add a certain amount of vcore when the processor is @ fullspeed.

Motherboard: asrock p67 extreme 6 + i7 2600k

I tested 8 hours yesterday Prime95 place-in Large FFT which succeeded.
Though this was with the motherboard 4.6 Ghz preset and used 1.360-1.365V

Since I heard that preset/or auto settings ussually give too much vcore I am trying manually, Prime is running for 40 min now, looks ok so far.
with Turboboost short/long and cpu core limit=275W 46x100 mhz Additional Turbo voltage 0.98V = 1.356-1.363V

Hyperthreading on, speedstep on, enhanced halt state on. Load line calibration auto but produces value 5 which is highest manual choice.

Basically everything you need to know about overclocking an i7-2600k. Got me to 4.5ghz without breaking a sweat. Also tells you how to get as high as 5.0ghz and what to enable to do so.

*The BIOS is EFI, but I'm sure you'll be able to work with the text he gives and not the screenshots.

No it doesn't I already saw that thread, but It doesn't mention Internal PLL overvoltage or offset voltage or additional turbo voltage and the differences.

So anyone??

Im trying to reach 5ghz 24/7 max temps end 70C or begin 80C max with max 1.425 Vcore or something which I would be comfortable with.
