Ddr2 Memory Slots - Abit AW8-D User Manual

2.5.2 DDR2 Memory Slots

This motherboard provides four 240-pin DIMM slots for Dual Channel DDR2 800/667/533
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.
