Bought two 8 gig Kingston Hyper Memory sticks for my PC from tigerdirect. Installed them but Windows 7 Professional is only reading 8 gigs. I've tested the memory slots and they both work. Both memory sticks work as well.
My motherboard is a Gigabyte GA78LMT-S2P
AMD Phenom II X6 1045T 2.6 GHz Processor
1 TB Hard Drive
ATI Radeon 3400 HD graphics card
Any help would be greatly appreciated
