Hopefully this will be of use to someone. I built up a rig, mainly for my wife (I use my laptop / console mostly these days). As she uses it all the time, it was kind of thrown together at default settings and it turned out it was rebooting all the time. I took it away this weekend, stripped it down completely and tidied all the cables up. It was still rebooting under failsafe settings.
Spec:
Gigabyte UD5, i7 920, 12GB Patriot 1600, Corsair H50.
Cycle #1:
Get the Patriot running at 8/8/8/24 with 6GB at stock. Upped RAM to 1.64, CPU to 1.3 and VPI PCC to 1.3. Real Temp Sensor test peaked at 69C
Cycle #2:
Added other RAM. QPI to 36. SPD to 8. BCLK to 150. Uncore to 16.
Peak CPU 73C.
Cycle #3
BCLK: 160, CPU 75C
Cycle #4
BCLK: 170. Started tracking CPU Volts.
1.216V, 76C
Cycle #5
BCLK 180, VCORE 1.216V, 77C. Occasional POST fail
Cycle #6
BCLK: 190, VCORE 1.216V, 80C
Cycle #7
BCLK: 200, Windows Bluescreens
Cycle #8:
QPI/VTT +1.340V, TRAS 27, DRAM to 1.66V
NO POST
Cycle #9:
BCLK: 180 78C (POST still fails sometimes)
Cycle #10:
BCLK: 175
CPU down too 1.281V, 75C, 1.2V measured VCORE
Cycle #11:
Step through RAM timings, one by one. Go from 8/8/8/24/2T to 7/7/7/20/1T
Cycle #12:
CPU volts to 1.268V
Temps 75C, VCORE: 1.184V
Cycle #13:
CPU volts to 1.256V
Temps 73C, VCORE 1.168V
Cycle #14:
CPU volts to 1.243V
Temps 72C, VCORE 1.168V
Cycle #15:
CPU volts yo 1.225
Temps 71C, VCORE 1.152V
Cycle #16:
CPU volts to 1.2V
Temps: 70C, VCORE 1.128V
Cycle #17:
QPI/VTT 1.28V
70C
Cycle #18@
QPI/VTT 1.24V
70C
This is where I called it quits, the system went from crashing underclocked at 2.0GHz to stable enough to run 50 rounds of BurnTest and following it up with 2 hours of Prime95 @ 3.5GHz
