2.4.2 Memory Configurations You may install 256 MB, 512 MB, 1 GB, or 2GB registered ECC DDR2 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_A3+DIMM_B3 =DIMM_A4+DIMM_B4 • 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.
