    1* PCIe x16 & 1* PCIe x1 Gen2.0 slots
    PCI Express Gen2.0 technology doubles the available aggregate bandwidth between PCIe Generation 2 cards and the motherboard. This means a Gen2.0 16-lane (x16) link can provide up to 16GB/s of bandwidth, 8GB/s in each direction.  PCIe Gen2.0 is backwards compatible, and so existing PCIe “Gen1” cards can be plugged into Gen2.0 slots.








    Dual-channel DDR3 1333/1066 MHz memory, 16GB Max.
