You cant use REGISTERED RAM. Or Buffered RAM.

Must be Non Buffered and the speed must be faster

DDR3 PC3-12800 • 9-9-9-24 • Unbuffered • ECC • DDR3-1600 • 1.35V • 512Meg x 64 • Low Profile •

The ram you bought wont EVER work.

Max ram is 16 gigs and it must be LOW Density and 4 GIG module size max.  This means 4 slots of 4 gig = 16 max ecc

4 slots of 2 gigs each = 8 gigs max NON ECC

So would tis RAM work in my system?
