2-3. Install System Memory

The Intel® 955X Express Chipset MCH memory interface is designed with Flex Memory Technology supporting single-channel or dual-channel DDR2 memory configurations.

•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.

Method		Channel A			Channel B
