Hello all. I was looking for a little help getting an O/C stable. I have an EVGA 680i SLI mobo, running a Intel E8400 Wolfdale. Stock speed on the E8400 is 3.0GHZ and right now I have it up to 3.6GHZ @ 1.35 volts. Oddly while running Prime95 however CPUID is reading only 1.296 volts? Anyway, I've had one of these before and I had it up to 4.0GHZ stable, but on a gigabyte board, where the bios was much less complicated.
So far at this point I've only pushed the fsb, and the core voltage, well plus some RAM playing around, but that really shouldn't effect the CPU O/C'ing as the mobo has a nice unlinked mode allowing me to push the CPU and RAM individually. What other forces should I play with to get it up to the 4 GHZ? Should I adjust the FSB voltage? In my bios it's telling me it's auto set to 1.3v, I'm not sure what the SPP and MCP voltages are for in the bios either, so I've left them untouched. My CPU multiplier is x9 @ 400 fsb, rated fsb is 1600. Oddly enough it seems that I can't get my multiplier any higher than x9.
So I've done what I really know here, and am looking for any advice to get my O/C stable, oh at 3.6 running prime95 my temps on each core are 50, and 46. I'm really looking to push the chip as much as possible without causing any damage to it, so any more advice you guys have for me would be greatly appreciated. Here are some screenies to show what I'm working with...
