Anyone having a problem booting with 3 sticks of RAM installed? If I try to boot with 3 sticks it hangs at "DET DRAM". But it will boot entirely into Windows and stable with 2 sticks, but not 3 or more sticks.

I've tried all of the following RAM modules in the RIIE:
-3x1GB Kingston DDR3-2000
-3x2GB CSX Diablo DDR3-2000
-3x2GB OCZ DDR3-1600
-3x2GB Crucial DDR3-1333

None of them work with 3 sticks, but they all work with just 2 sticks installed. And all of them work in my P6T Deluxe.

I've tried BIOS 1001 and 0903, same result.........no boot with 3 sticks. Tried CMOS, boot with 1 stick, then 2, then 3......not working.

Anyone had this and/or fixed it?
