GA-MA770-UD3 v1 losing Raid 1 array after 3 days

I have the above mobo with an AMD7850 processor, and 2 500GB Seagate sata drives configures as Raid 1. OS is Windows 7 Home Premium.

My problem is that the raid array will only stay visible for approx. 3 days (the PC stays on 24/7 as it is a media server as well as my main PC), only way to resolve is to hard reset the machine (yes, the OS is on the raid array).

I'd read somewhere that earlier versions of my boards bios were unstable for raid arrays, so I upgraded bios from F5 to F8. This, sadly, didn't work.

Is it worthwhile upgrading the bios to F9G, or could there be another cause? Any tips? I'm a bit of a newbie when it comes to settings in the bios, so any help appreciated.

  1. I am assuming that you installed the RAID correctly, and that you performed the preinstall F6 of the RAID drivers? If not that is your problem - you can create an installer {if you do not have a FDD}. Use

    Next, try updating you BIOS to the latest version {Rev 2.1} is FKB.

    Next, either exchange your MOBO; otherwise purchase a simple RAID Controller card.

    RAID 1, 0, and 10 are as simple as it gets so, as an option, pretty much any RAID Controller will work. I prefer Adaptec.

    Yes, many GA's on-board RAID seem to be faulty.

    Good Luck!
