We had some storms come through Austin last night and this morning - so I have had everything unplugged from the wall - so I am back up and running now.

I did some baseline testing with OCCT using the LinpacK test with memory @1066 7 7 7 20 FSB @333 and CPU @3.33 GHZ - OCCT reports hottest core temp @61.
Tested Flight Simulator X for 2 hours (same configs) with affinity mask set to 14 (to use 3 cores) and HWINFO reported highest core temp @50.

The next step is to test the CPU @ 3.66GHZ (333x11) and test leaving RAM @1066. Reading through the info ProfJim found - it looks like testing the RAM past 1333 may be a waste of time. I know Corsair tries to make their chips compatible - so lower speeds/higher timings may be the compromise to achieve this.
It looks like DDR3 1600 (2GB sticks) may be a gray area with respect to P45 chips.
I noticed on Crucial's website that they don't even make matched pairs (2x2GB) of 2GB DDR3-1600 - only 1GB sticks. Interesting.

Will report findings later this evening.

Thanks again ProfJim for the primer on OCCT.
