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
DIMM_A3+DIMM_B3=DIMM_A4+DIMM_B4
Dual CPU:
DIMM_A5+DIMM_B5=DIMM_A6+DIMM_B6
DIMM_A7+DIMM_B7=DIMM_A8+ DIMM_B8
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.
