I purchased a 6017R-TDF. Motherboard is X9DRD-IF. I tried to install a LSI 9260-4i RAID card (PCI-E x8 GEN 2) on top of the riser card RSC-RR1U-E16 (GEN 2). I have set the PCI-E slot to GEN 2 speed. With riser card, the card cannot be recognized when I installed OS (Windows 2008). Without riser card, the card can be recognized when I installed OS (Windows 2008). I noticed that X9DRD-IF BIOS does not have the option to force slot to recognized x4, x8 or x16. (Compared with X8DRI-F). Please advise.
Riser card rev 3.6 with auto detection feature should solve the issue.
