CPU Ratio and Spread Spectrum

post #1 of 3
Thread Starter 
Hey guys, so trying to refine my OC here, was previously at 4.1GHz, 1.35v, 100% LLC.

What are the best multipliers to use? I know it's always better to use 21x or 19x over 20x, is there anything else? Being an unlocked chip I can do any multiplier I want, but it'd be best to know if there are any known combos that work better than others.

What does the CPU Spread Spectrum do? Many of the guides I've read recommend I turn it off, but leaving it on usually gets me through 30 passes of IBT, while leaving it off makes it impossible for me to pass two...

Thanks!

But I could not put it better myself.

Theoreticly, the best MP to go for is a low MP with a high FSB.
The higher frequency's on your other parts like QPI link and RAM will give the system more bandwith and overall performance.
On the other side: having other parts running at hihg frequencys also gives more instabillity to those parts.
Not much of an answer but: figure out what MP & Bclck works best for your system smile.gif

(wat does LLC stand for btw? )
