I have a similar problem, this is my first build and I have a MSI X79A-45GD plus motherboard with a LSI SAS/SATA controller card for a PCIe x8 but I put it in a PCIe x16 slot and it seems to work accept for the fact that windows 8.1 keeps telling me it cannot load the OS to the HDD I selected. I cant seem to any driver for my HDD (Seagate cheetah 15k.7) x3. Sometimes I wonder why did I even start this.
