I have this exact board (Rev 1.x) and it has been working solid for years now. However, even if this is not a straight answer to your question, I have to warn you about several speed problems concerning the on-board RAID controllers (either SATA or PATA). How to recreate the problem: First get the latest BIOS for this mobo, it must be the F11 and Gigabyte has never released a newer version. Second create a RAID volume through the RAID-BIOS (PATA or SATA, I tested heavily on PATA) and watch as your disk speed crawls to the floor (yes even on M$ OSes). This is fixed in later BIOS revisions of the RAID chips, but since they are integrated on the board, these BIOSes are updated only when the main BIOS is updated (The main BIOS file contains the BIOSes for the RAID chips) The solution is to mod your BIOS with the most recent RAID BIOS. More info here... http://www.nforcershq.com/forum/image-vp567696.html I have followed these instructions to the letter and have successfully modded my F11 BIOS to overcome the disk speed problem using the pseudo-hardware RAID controller.
