ok, i got windows installed and working but i can't seem to get the 5v setting working. i didn't do anything really different to get windows installed so i can't pinpoint what's going on. i'm thinking it might be the zippy as strange as it sounds. i noticed if i plug in extra hard drives the board won't boot, same as i get when i change to 5v vdimm. i've got these components hooked up:

fx55, x850xtpe, dfi nf4 sli-dr, ocz 4200el
zippy 6701P, vapoLS
aquaxtreme50z 12v pump
4 sata hard drives
1 ide hard drive
1 dvd-writer
2 sanyo denki 120mm fans
1 adda 120mm fan
1 vantec fancard
