I just built a system with this board. It works good at stock clock speeds with a 1090T. The problem I'm having is that whenever I set the SATA type to RAID, there's about a 60 second delay between the system bios boot screen and the raid bios boot screen.

I have an OCZ Vertex 2 as my boot drive and two 500 gb seagate drives in a raid 1 for data storage. MSI sent me bios 1.45 which I don't think is released yet and this didn't help. I shut off the raid and used AHCI, then I used software raid in windows 7. MSI had me try all kinds of crap and now they want me to RMA the board.
I really liked this board at first, but then this happened. Now correct me if I'm wrong, but if I want to run a second graphics card at 16x, will it block the only PCI slot on the board? That's where I have my X-Fi sound card....
This is the first time I strayed away from Asus. If I have to send this board anywhere, I'm sending it in for a refund and getting the Crosshair
If anyone wants to check out 1.45 bios, let me know.
