Thought I would bump this Thread as I too am having the exact same issue with the Mobo and a Sandisk Ultra II 960GB SSD!
Blu-ray DVD burner works great and shows up in the bios on the Grey Sata III. Also, have a raid 1 mirror that works great on the SATA II (blue ports), along with the Sandisk also on SATA II blue ports.
NO joy however with the Sandisk on the SATA III port, whether it be AHCI, IDE or RAID (which is the mode I use currently...). Won't even ID in the bios. I would VERY much like to get it working on the other GREY SATA III port and hope I can move it there without having to re-install!
