How to enable Dual-Channel DDRII:
1. This mainboard provides Dual-Channel functionality for the four DIMM sockets. Enabling
Dual-Channel can significantly increase your data access rates. DIMM1 and DIMM2 share one
channel, and DIMM3 and DIMM4 share another channel.
For enabling Dual-Channel, you have to install memories in different channel of DIMM
sockets; 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.
For example: If you install one 256 MB memory in DIMM1 and one in DIMM2 (256MB x 2 =
512MB), you must install a total of 512 MB memory in DIMM3 or DIMM4, so that the
Dual-Channel can be enabled.
2. If you only need to install one memory, it is recommended to install it in DIMM1 or
DIMM3.
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.

actual installation may vary slightly from the pictures.
