Default Re: GA-EP45T-DS3R DDR3-1600 So far so good

OK - here is the latest,

I think maybe the problems I have encountered have been due to an undervoltage of VCore. Memory has been set to run at 1066 - to take it out of the equation.

I can run OCCT small data set @3.00GHZ (333X9) stock voltages with no problem, 3.33GHZ (333X10) with a small increase in Vcore to 1.2652V.

When I get the CPU up to 3.66GHZ (333X11) the system will reboot about 1 minute into the test at anything less than 1.3125V.
OCCT fails after about 5 minutes into the test - but does not reboot system (VCore@1.3125V).

However, there is discrepancy between the Vcore setting and actual voltage shown.
In Bios VCore is set to 1.3125 - in PC health screen Bios shows actual VCore @1.268.
In Windows: OCCT shows unloaded CPU @ 1.26, CPUZ and Easytune both show 1.264V.
Not sure if this is just normal variations or the engineers skewing the voltage a little so less people fry their CPU's.

So, my thinking is that VCore is still a little low in real voltage - which is causing the failure - I didn't want to take it any farther until I got ProfJim's input.
