How to enable Dual-Channel DDRII:
1. These mainboards provide Dual-Channel functionality for the two DIMM sockets. Enabling
Dual-Channel can significantly increase your data access rates. DIMM1 and DIMM2 share one
channel.
2. For enabling Dual-Channel, you have to install two memories in the DIMM sockets at the same time;
according to the definition by Intel, once one channel of the memory capacity is the same with the
other channel, then Dual-Channel will be enabled.
3. For example, if you install one 256 MB memory in DIMM1 and the other one in DIMM2 (256MB x 2 =
512MB), so that the Dual-Channel can be enabled.
4. If you only install one memory, then the Dual-Channel won’t be enabled.
Memory Installation Steps:
1. Pull the white plastic tabs at both ends of the slot away from the slot.
2. Match the notch on the RAM module with the corresponding pattern in the DIMM slot. This will
ensure that the module will be inserted with the proper orientation.
3. Lower the RAM module into the DIMM Slot and press firmly using both thumbs until the module
snaps into place.
4. Repeat steps 1, 2 & 3 for the remaining RAM modules.
