I am using Asus P4G8X mobo. Have not managed to get RAID working. My supplier said I could use Asus dongles to turn my IDE HDD's into Raid HDD's this did not work. I sent an e-mail to Asus, who replied within two days to say the dongles were not supported. I have sent another e-mail to ask which Raid HDD's are supported by the mobo. If I receive a reply giving me the information, I am hoping to get the Raid working. Thought the information may be of interest. Hope you get up and running soon.
would recommend this board to anyone. It is a great buy and i find the onboard audio to be especially good (although i dream of 5.1 surround sound system). It is a sturdy board and well made. no complaints
