I built an I7-860 system about 3 months ago. I had just upped my core clock a bit, and had it stress testing Prime when I went to the gym. I came home and the thing was off. Tried to turn it back on, and it started for a moment, and turned back off. I breadboarded it, and tried a different PSU, with the same results, I also tried removing all but 1 stick of RAM, along with changing slots, with no luck. I get the same beep pattern regardless, it is several very fast beeps, for about 1 second, then either shuts off, or repeats again.
My system is:
8 gig kingston 1600 DDR3 Ram
BFG 275 GTX
at the time of the meltdown:
QPI voltage: 1.31
CPU voltage 1.35
RAM voltage 1.64
RAM clock: 1820
It was running right around 4Ghz, I think around 4.07Ghz
I've got it down to either being the mobo or the CPU. I know my CPU voltages where high, but I didn't think they were high enough to cause this kind of damage. While stress testing with Prime, I run right around 80C (I have HT on)
The beeps from the speaker are very fast, and I cannot tell if they are constant pitch (meaning a power problem, which I assume would mean a short in the mobo since I tried a different PS)
yea they were right around 80C before I left (under full load, with HT on). I'm about 90% sure its the mobo at this point, I ordered a new one today, should be here tomorrow, so hopefully that fixes the problem.
