• 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, 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.
• Some old-version DDR2-667 DIMMs may not match Intel
®
’s On-Die-Termination (ODT)
requirement and will automatically downgrade to run at DDR2-533. If this happens,
contact your memory vendor to check the ODT value.
• Due to chipset limitation, DDR2-667 with CL=3 will be downgraded to run at DDR2-533
by default setting. If you want to operate with lower latency, adjust the memory timing
manually. There will be 4MB reduction in total memory when enabling ASUS Thermostat
function under Single Channel mode.
