Memory Configurations

You may install 256 MB, 512 MB, 1 GB, 2GB, 4GB OR 8GB registered ECC
DDR2 667/533/400MHz DIMMs into the DIMM sockets using the memory
configurations in this section.
• For dual-channel configuration, the total size of memory module(s)
installed per channel must be the same for better performance.
Single CPU:
DIMM_A1+DIMM_B1=DIMM_A2+DIMM_B2
Dual CPU:
DIMM_A1+DIMM_B1=DIMM_A2+DIMM_B2
DIMM_C1+DIMM_D1=DIMM_C2+ DIMM_D2
Quad CPU:
DIMM_A1+DIMM_B1=DIMM_A2+DIMM_B2
DIMM_C1+DIMM_D1=DIMM_C2+ DIMM_D2
DIMM_E1+DIMM_F1=DIMM_E2+DIMM_F2
DIMM_G1+DIMM_H1=DIMM_G2+ DIMM_H2
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from
the same vendor. Refer to the DDR2 Qualified Vendors List at the
ASUS web site.
