You might give Gigabyte support an email request and ask. I sent an email support queston to A Data and they answered the next day. I use the A Data successfully on three different boards. The ASUS P5B Deluxe and also an ASUS P5B-VM DO and it works fine on an ASUS P5LD2-VM 945 also. The RAM works and you can't beat the price especially if you need a couple of GB's around to troubleshoot. It would not run at 4-4-4-12 on the two 965 boards, but did on the 945 board.
