Kemical,
How can you update to 1540.151 version, since it does not include anywhere the 438x PID for SB600 device ? After the update, does AMD AHCI Compatible Raid Controller in Device manager show the updated driver version, or the initial ?
I now use drivers 2.501.1540.48 for RAID volume recognition at beginning of Win7 installation. These are from DFI website, for DK 790FX-M2RS board, also having SB600.
I also concluded after extensive trials, that RaidXpert 2.4.1540.26 dated 22/5/09 from game.amd causes instabilities in my Raid-0 SSD setup. "Task 30 timeout" error was very common for small file size Read/Write in ATTO benchmark and after that event, NCQ was disabled in one or both SSD's. For reference, NCQ should be enabled for SSD's to get nominal performance.
I yesterday installed RaidXpert 2.4.1540.27 from ASUS Download site (under model M4A785G-HTPC/RC). So far seems to not have the same issues.
I'll update with ATTO benchmark for the SSD Raid-0 OS volume when i get home.
