The following figure illustrates the location of the sockets: A8N-VM CSM DIMM_A2 DIMM_A1 DIMM_B2 DIMM_B1 ® A8N-VM CSM 184-pin DDR DIMM sockets Channel Channel 1 Channel 2 Sockets DIMM_A1 and DIMM_B1 DIMM_A2 and DIMM_B2 1.7.2 Memory configurations You may install 128 MB, 256 MB, 512 MB, and 1 GB unbuffered ECC/ non-ECC DDR DIMMs into the DIMM sockets using the memory configurations in this section. • Installing DDR DIMMs other than the recommended configurations may cause memory sizing error or system boot failure. • Install only identical (the same type and size) DDR DIMM pairs for each channel. • Always install DIMMs with the same CAS latency. For optimum compatibility, we recommend that you obtain memory modules from the same vendor. • Due to chipset limitation, this motherboard does not support DIMM modules with less than or equal to 128 Mb memory chips. • If you are installing only one DIMM module for a Single-channel configuration, install the module on DIMM_A1 (blue slot).
