Make sure to unplug the power supply before adding or removing DIMMs or
other system components. Failure to do so may cause severe damage to both
the motherboard and the components.
When installing long AGP cards, it is recommended to install the memory
modules first. Long AGP cards, when installed, may interfere with the memory
sockets.
1.7.2 Memory configurations
You may install 64MB, 128MB, 256MB, 512MB, and 1GB DDR DIMMs into the
DIMM sockets using the memory configurations in this section.
Important notes
• Installing DDR DIMMs other than the recommended configurations may
cause memory sizing error or system boot failure. Use any of the
recommended configurations in Table 1.
• A three-DIMM configuration is not supported on this motherboard
• In dual-channel configurations, always install an identical (the same type
and size) DDR DIMM pair on sockets of the same color.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor.
