Ok.. Problem solved!!!

I went to the store, returned the Corsair and got some Crucial tactic DDR3 (4x4GB)... They worked fine on the first try...

Quick update for an old post on an even older system. I purchased a Xeon X5470 (10x multiplier, Socket 771, 12MB Cache, Quad Core) for dirt cheap on Ebay. Applied 771/775 mods to the CPU/Socket, updated the F2a BIOS with Xeon Microcode and installed the X5470 in my GA-P45T-ES3G. Runs perfectly at 4GHz (FSB 400) and Prime temps max at 68C (air cooled). Prime stable for 24 hours. Lightning fast (for me).

VCore: 1.3
VTerm: 1.2
VRef: .805
MCHCore Voltage: 1.3
All CPU power saving features are ENABLED in BIOS

Memory: Crucial Ballistix DDR3 1600 8-8-8-24

Note that the Xeon E5450 also runs great on this MB at 3.6GHz (400 FSB) with the same 771/775 mods.
Note also that some GA-P45T-ES3Gs will achieve FSB 400 and some won't. I have one that does and one that doesn't. Need good Northbridge cooling to achieve stable FSB 400. Good copper Northbridge heatsink and Arctic Silver 5 will do the trick.
