Installing DDR2 DIMMS other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of
the recommended configurations in the table on the next page.
Install only identical (the same type and size) DDR2 DIMMs in
DIMM_A1 and DIMM_B1.
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 resource allocation, the system may detect less than
2 GB system memory when you installed two 1 GB DDR2 memory.
If installing only one DDRII DIMM, please install it in DIMM_A1 or A2
first.
This motherboard does not support memory modules made up of
128 Mb chips or double-sided x16 memory modules.
