Long story short:

Got a rampage formula from the egg, it runs fine but no post with 8gb ( 4 x 2gb) of OCZ Reaper (OCA2RPR800C44GK, PC2 6400 4-4-4 @ 2.1v). Post just fine with 6gb @ 800. I tried everything I can possibly think of..like lower the ram to 667, lower the timing to 5-5-5-15 2t with 2.1v, crank up the nb or sb voltage. everything...no luck..

Is there anyone with a similar setup? or I'm just SOL?

Anyone has a rampage formula with 8GB? cuz if I can't get it to run at 8GB I may have to switch ram to sth that would work 8gb at full speed with this mobo.

Thanks a lot. I would really appreciate any inputs.
