Hi there, does anybody know how to downshift the DX79SI motherboard permanently to PCIe 2.0 speed or less ? Considering that PCIe 3.0 isn't really supported by the Sandy Bridge CPU (the only one supported by the board) I don't understand why the new generation of RAID controllers try to run at the higher speed ? Both LSI's, Intels and Adaptecs newest controllers all refuse to work with the DX79SI board. At least the Intel RS3WC080 boots up but since its running at 8 GTs its unstable. The Adaptec series 7 controllers refuse to work at all. The board doesn't boot with a POST code 51 error.
