Asus M2N68-AM PLUS User Manual - Page 13

• 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 the 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 the 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 4GB or more memory is installed on the motherboard. • This motherboard does not support DIMMs made up of 256 megabits (Mb) or less. • 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 efficient cooling system to support a full memory load (2 DIMMs) or overclocking conditions.
