Hey Daniel,
I tested the 3 new DIMMs as you described, they worked fine @ 1333MHz. I then added another triple of the old DIMMs and got up to 24GB (I did not notice if it down-clocked it). Finally I added the last triple to total 36GB @ 800MHz.
Am I really sacrificing much performance at 800MHz? I added the memory to boost my VMs from 3GBs of vRAM to 4GB. Do you think I will notice all that much?
Thanks,
Joe
