1.7.2Memory 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).
