I want to expand the memory in my HP/Compaq 6000 Pro with a HP 3048H motherboard. Specs call for DDR3 PC3-10600. I picked up a Kingston 8GB kit (2x 4GB) of their HyperX Genesis (KHX1600C9D3K2/8GX) and the board won't POST, just producing 5 long beeps indicating a memory error. I checked the seating/slots, etc, but no go. The memory does support XMP, though I don't think this board does. Any thoughts?
