2-3. Install System Memory

This motherboard provides four 240-pin DIMM slots for Single/Dual Channel DDR2 667 memory modules with memory expansion size up to 8GB.

•To reach the optimum performance in dual-channel configurations, install identical DDR2 DIMM pairs for each channel.

•Install DIMMs with the same CAS latency. To reach the optimum compatibility, obtain memory modules from the same vendor.

•Due to chipset resource allocation, the system may detect less than 4GB of system memory in the installation of four 1GB DDR2 memory modules.

•Due to chipset limitation, 128MB DIMM modules or double-sided x16 memory chips are not supported.

There are several methods of different DDR2 configurations depending on how the DIMMs are populated on each system memory channel:

•[Single Channel]: only one channel is populated.
