We have a Mac Pro from 2010 (dual processor 5,1) that currently has 4x2gb RAM sticks in it. Apple System Profiler reports them as DDR3 ECC at 1333 mHz. There are 4 empty slots and I was hoping to put two more sticks in (2x4gb). Will these Kingstons work with the computer and with the other DIMMs that are in it? http://www.newegg.com/Product/Produ...0139150&cm_re=ddr3_ecc-_-20-139-150-_-Product Thanks!
