You may install 128 MB, 256 MB, 512 MB and 1 GB unbuffered ECC or
non-ECC DDR DIMMs into the DIMM sockets.
• 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.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor. Refer to the DDR Qualified Vendors List on
the the ASUS website for details.
• In dual-channel configurations, install only identical (the same type
and size) DDR DIMM pairs on each channel.
• Due to chipset resource allocation, the system may detect less than
4 GB system memory when you installed four 1 GB DDR memory
modules.
• Three DDR DIMMs installed into any three memory sockets will
function in single-channel mode.
