ASUS M3N-HT Deluxe/HDMI 2-13
2.4.2 Memory configurations
You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC and non-ECC
DDR2 DIMMs into the DIMM sockets.
Recommended Memory Configurations
• You may install varying memory sizes in Channel A and Channel B. The
system maps the total size of the lower-sized channel for the dual-channel
configuration. Any excess memory from the higher-sized channel is then
mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same vendor.
• If you install four 1 GB memory modules, the system may only recognize less
than 3GB because the address space is reserved for other critical functions.
This limitation appears on Windows
® XP/Vista 32-bit operation system which
does not support Physical Address Extension (PAE).
• If you install Windows ® XP/Vista 32-bit operation system, a total memory of
less than 3GB is recommended.
• This motherboard does not support memory modules made up of 128 Mb
chips.
