Trouble with i7 860

post #1 of 8
Thread Starter 
i'm trying to overclock to 4.0ghz and i'm having trouble with voltages its not stablizing.

191 x 21 1146 (2:6) VTT 1.24550, vcore 1.22 to 1.36v, i've stabilized the base clock and memory while it was 191 x 15 1528 (2:8) vtt 1.24550, then moved on last to bringing up the cpu, i've had it close to being stable with these settings:

191 x21 2:8 (1528) 1.30vcore, 1.24550 vtt. but intelburntest (maximum) 8 threads 5 laps gave me a critical error for being un stable no blue screen though. ( my cpu pll was 1.80 here and dram volt was 1.60. so i tryed increasing the vcore by increments now i'm up to

191, x21, 2:6, 1146, vtt 1.24550, vcore 1.36v, cpu pll 1.90, and currently passing 4/5 intelburn laps. Also note i'm getting huge vdrop while idle bios says 1.36vcore, cpuid is saying 1.37, andthen while under load its vdroop up to 1.39vcore. This is with LLC 100%, i've tryed LLC 0% and it goes opposite way instead of 1.35Vcore it would be 1.27vcore, also tryed 50% LLC and it is similiar to 1.275vcore.

My next idea is to try a different comination like 200bclk 20x? Any ideas?

Can you lower the PLL to 1.74 ?

raised the vcore by one increment and changed the dram timings to 9/9/9/27/N2 and its doing maximum 8 threads 4/5 laps at the moment I think it will pass thanks for all the advice.
