• 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.
• 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.
Due to OS 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.
