2.2 Upgrading system memory
The motherboard comes with eighteen (18) Double Data Rate 3 (DDR3) Dual Inline
Memory Modules (DIMM) sockets.
You may install 1 GB, 2 GB, 4 GB and 8 GB registered DDR3 DIMMs with ECC
or 1GB, 2GB and 4GB unbuffered DDR3 DIMMs with ECC into the DIMM sockets
using the memory congurations in this section.
Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor.
For CPU1 conguraton, when installing only one DIMM, install it to the
orange slots labeled DIMM_A1, DIMM_B1, or DIMM_C1.
For CPU2 conguraton, when installing only one DIMM, install it to the
orange slots labeled DIMM_D1, DIMM_E1, or DIMM_F1.
