QUOTE(ah_khoo @ Jul 6 2008, 01:49 PM) increase bit by bit, don't anyhow increase alot just to take shortcut. when i was on f3, i did play with d sb voltage abit. by bumpin it abit it did manage to brin down d vcore needed but after awhile, d effectiveness gone. so i just brin it back to stock. never touch d htt voltage as i've tried increasin it for moderate oc, yes it doesn't help. do note that ur playin w 4 sticks of ram, so u tend to need higher voltage for vcore & vidimm if there's any oc done.  ya im thinkin of shortcut . . . now im just using 2 sticks, the other two couldnt be detected by my board since last night ( does it mean i hav to RMA). My vcore is 1.55, vdimm is 2.15, here latest test . . . stable slightly longer with nb volt of 1.35.

Just tried fsb 280, multi 12x = 3360mhz, vcore 1.525, vdimm 2.1 . . . ran orthos blend stable for 3 hours. Tried on mutli 15x, 13x, 11x with speeds till ~3360-3380mhz . . . all couldnt even run 30mins in orthos blend. Btw just wanna ask, psu does play a role in ocing right?

Vdroop is meant for intel procs only? . . . dp correct me if im wrong. Prob now is, my bios is set 1.55vcore, but in everest, cpu-z n asus ai booster only shows 1.49-1.52 only . . . could that fluctuating voltage cause system instability?
