Re: The trek to 3.8 Ghz+ on E8400
I'm stopping at 3.9Ghz. At 4Ghz, I was able to boot to desktop each time, but I couldn't keep the system stable. I even increased the voltages on the CPU to 1.275V and memory to 2.1V. Neither was enough to keep the system stable for more than about 5 minutes.
I think 3.9Ghz @ 1.25 Vcore and Memory at 868mhz @ 2.0V is pretty dang solid though. I'm impressed that the system was able to get this high on such low voltages.
I also think that it's not the processor or the memory. I think it's the motherboard (Gigabyte GA-EP45-UD3R). The northbridge is passively cooled, and it felt fairly hot to the touch when I had the system @ 4Ghz. Granted, for a $120 motherboard, this thing is kick ass! I wish my 680i SLI would do such an overclock this effortlessly.
I think that's it. Anyone have any suggestions as to what to do now? I want to fine tune it by tightening the timings one by one and pulling down the voltages little by little. Any other suggestions?
