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.
