P6N diamond mobo problem loading vista with Nvidia raid

[quietfly]

I have a new P6N diamond mobo and i'm having a problem loading vista with Nvidia raid. when raid is not enabled on the mother board i can load vista fine, but if i attempt to enable raid in the bios and then configure the array in the Raid bios, vista stops loading the setup after the first scrolling bar.

my setup is:
MSI p6n diamond
intel e6420
4gb Gskills pc2 6400
wd raptor 1500adfd x2
wd caviar wd500sys x4
egva 8800gts

I'm not trying to over clock anything yet the memory is set at the manufacture default of 4-4-4-12 and @ 2.0 volts

I've been able to confirm the issue by loading vista on to an un-raided drive and then stress testing using prime 95 and memtest for 6+ hours.
If i could get it to boot into setup I would attempt to use the modded drivers listed on this site.

does any one have any ideas?

thanks!!
