Okay folks.
Since I started this thread, I have tried to overclock my maching from orginal 3.5 to 4.7
I have been flying my FSX in DX10 at 4.5 for about a month now at a stable environment.
Although I have yet flown my FSX under 4.7 (since I just tried this boost this morning),
I have now achieved the attached results.
Intel Burn Test with stress level at high and running it 15 runs
with the success message appearing at the end.
I have set my vcore at 1.470V to achieve this result. When lowered to 1.460V,
I would get BSOD during my Intel Burn Test (high stress level at about run #6).
My worry is that my CPU temp goes up to about 95 degrees (although not during the whole test)
when using my Intel Burn Test.
Of note, my current CPU temp (just using the web browser to type this) is around 40 degrees
but my Core speed is spooled down to 1.6GHz.
Are these indications that my PC is stable now at 4.7GHz?
(I have liquid cooling by the way)
