I posted earlier the specifics http://www.xtremesystems.org/forums/...181921&page=20

ASUS sent me a new motherboard (thanks ASUS ). Crucial sent me new RAM (thanks Crucial) . I'm still having memtest errors .

I increased tRFC as Reatlelstar suggested. I dropped timings to 5-5-5-14 and had tRFC up to maximum, around 132 if I recall correctly. This is at 800mhz.

It's starting to look like the RAM just isn't compatible. The DDR2 800 2x2Gb Ballistix aren't on the QVL for the Rampage, but the 2x1Gb Ballistix are. I've talked to Crucial and they have mentioned that they did test the RAM on the Rampage (at least one of the customer service reps mentioned this, I don't know how accurate this info is.) I haven't talked to Crucial since yesterday. Thirty minutes on hold sucks on a cell phone.

Is there anything that you guys can see that I am overlooking.

I'm probably just gonna get some G.Skill RAM since everyone else is doing it (peer pressure).

Do you think Crucial can give me a refund since there product doesn't work (it's way past the 30 day mark)? Would it be ethical to sell them when I'm not 100% sure that the Ballistix are good?
