I had a similar problem with the same motherboard and hard drive, and a BIOS upgrade fixed it for me.
Mine actually showed up in the BIOS, but it only showed up as a 750 GB drive. Windows saw the entire 3 TB, but the BIOS did not.
The reason that I wanted the BIOS to see it was so that I had two drives and I wanted to set them up as RAID 1.
