• Due to chipset limitation, this motherboard can only support up to
8 GB on the operating systems listed below. You may install a maximum of
2 GB DIMMs on each slot.
• The memory modules may require a better cooling system to work stably
under full loading (4 DIMMs) setting.
2.4.2 Memorycongurations
You may install 512 MB, 1 GB, and 2 GB non-ECC, unbuffered DDR2 DIMMs into
the DIMM sockets.
• 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
conguration. 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.
• When installing total memory of 4GB capacity or more, Windows 32-
bit operation system may only recognize less than 3GB. Hence, a total
installed memory of less than 3GB is recommended.
• This motherboard does not support memory modules made up of 128 Mb
chips.
