Hi Skorpn and thanks for the speedy reply. I had the Rampage II Extreme and paid an extra $200 to upgrade to the Rampage III just so I would have SATA3 ...I am going to puke now. Okay, so forgetting about the Marvell controller (it will always be Maxell to me), why might Crysis crash so consistently on my Intel controller when in Raid 0? Keep in mind that I have tried it with two different sets of drives (OCZ SOlid x 2 and OCZ Vertex3 x2), and I have tried several different stripe sizes. The system seems otherwise stable. It is not a BSOD but just tells me that DirectX has crashed. On the very same install cloned to one of the drives but NOT in raid 0, it never crashes. Any ideas?

I am still fuming about throwing $200 away for two ports I wont even be using.

THANKS AGAIN FOR THE HELP!
Kirk
