I feel that if I pay 300$ for a motherboard, it should run as advertised. The QVL lists crucial ballistix, just not the higher density (they don't list any sticks with 2Gigs per stick) How can you populate 4 slots with 8GB RAM without using 2GB sticks?

The rampage may not like crucials*, or your timings (it wouldnt be the first board). Before rma i would test
1) 5-5-5-15, trfc 55+, all rest auto
The RAM is listed as 4-4-4-12, I didn't even know what trfc is. The sticks have chips on both sides.

One thing I find very strange is that it passed memtest after I flashed the BIOS with 0403 and then a day later it was failing again.
