Hello.
I have a Poweredge T610. I am using 4, 4 GB sticks of RAM. This memory is Dual rank, 1333mhz, Registered ECC.
I have dual CPUs and have the memory setup in Advanced ECC mode: Memory is in slots A2, A3, and B2, and B3.
From what I can tell from the manual here: 
This setup should be running at 1067mhz, but it only comes up as 800mhz. I can't see a way to adjust this via the BIOS. Do I have something configured wrong, or is there something else I need to do to make the memory come up at the faster speed?
Thank you.
