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).
