I have a few questions i've written down from my recent OC of my asus rampage II extreme motherboard with an Intel i7 920 processor. Hopefully the pro's can answer these.
I achieved a 3.9ghz stable OC on stock voltage settings. My max load temp is 64 degrees C; Norm temp is 37 degrees C. My bus speed was at 180 and multiplier at 21. I did raise processor core voltage to 1.3v and also uncore voltage to 1.3v; kept cpu pll voltage at 1.8v. Got to a 4ghz OC with a bus speed of 190 and temps raised to 80 degrees C under full load but did not test any farther.
I have a few questions branched from this OC:
1. First off, when testing using Prime95, should i use small ffts, large ffts or blend? I do know blend is more for ram, i've read a lot of controversy over which is better for oc stability testing; small or large ffts.
2. When increasing voltage and temps will this will cause my processor to die faster even withing safe temps (80 Degrees). How much faster will this cause my processor to die? I'm wondering if the added voltage and increase in the OC would be worth the years shaved off? I bet i could easily get to 4.2v w/this chip. I ask because the last pc i bought was 7 years ago; and it still works great!
3. Is the 21x multiplier is unlocked in a rampage II extreme? Can anyone confirm this? And if this is the case, when i set the multiplier to 21x does it even matter if turbomode is on?
4. I have been using Everest, CPU-z, prime95, and intel burn test. I run intel burn test on max, and auto on threads and for 10 passes; dont know if this is correct. Also i have been wondering where i can find the total power in watts the computer is pulling?This would help me confirm unlocked 21x multiplier.
*edit* i'm a little confused on which settings in my bios turn the turbo mode on/off. I'd like to keep it enabled bc i hardly will ever have 100% load on my cpu but i think with setting the voltage and multiplier to 21x that turbo mode is unable to throttle the performance down when idle.
