• 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 conguration. 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, we
recommend that you obtain memory modules from the same vendor.
• Due to the memory address limitation on 32-bit Windows OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you install a 64-bit
Windows OS when having 4GB or more memory installed on the motherboard.
• The default memory operation frequency depends on its SPD. Under the default state,
some memory modules for overclocking may operate at a lower frequency than the
vendor-marked value.
• For system stability, use a more efcient cooling system to support a full memory load
(2 DIMMs) or overclocking conditions.
