Memory Population Rules
This mainboard supports DDRII 533/667 FBD memory interface.
Each DIMM slot supports up to a maximum size of 4 GB. Users can install either single-
or double-sided modules depending on their needs.
Important
1. To enable successful system boot-up, always insert the memory modules
into the DIMM 11 first (Channel1/ 1st).
2. In dual-channel mode, Channel 1 works in pair with Channel 2 while Channel
3 works in pair with Channel 4. In other words, Channel 2 cannot work
independently with Channel 1 unplugged and Channel 4 cannot work alone
with Channel 3 unplugged. Channel 3 & 4 cannot work when Channel 1 & 2
are unplugged.
3. In dual-channel mode, DIMM modules must be of the same type and density.
