You may install 256 MB, 512 MB and 1 GB unbuffered 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. Use any of
the recommended configurations in Table 1.
• Due to chipset limitation, this motherboard supports a maximum of
4GB total memory and four (4) ranks per memory channel only. A
warning message appears during POST if the total density of
memory modules installed exceeds the chipset capacity. Excess
memory will not be utilized by the system.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.
• Due to chipset limitation, DIMM modules with 128 Mb memory chips
or double-sided x16 memory chips are not supported in this
motherboard.
• Use only qualified DIMMs modules on this motherboard. Visit the
ASUS website (www.asus.com) for the latest DDR2 Qualified
Vendors List (QVL).
