What I'm suggesting is:
module A1 = slot 0:0 module A2 = slot 1:0 module B1 = slot 0:1 module B2 = slot 1:1.
Addendum: I got curious and looked at Intel's DDR architecture whitepaper and also threw some queries at Google. Here's a very interesting summary and I think it can be trusted as the info originates from Crucial's engineering dept.: http://www.buildorbuy.org/dualchannelddr.html "Dual Channel memory configurations will provide increased performance over Single Channel configurations. Note: Memory channel speed is determined by the slowest DIMM module populated in the system. Rules to Enable Dual Channel Mode To achieve Dual Channel mode, the following conditions must be met: 1. Matched DIMM configuration in each channel 2. Same Density (128MB, 256MB, 512MB, etc.) 3. Same DRAM technology (128Mb, 256Mb, or 512Mb) 4. Same DRAM bus width (x8 or x16) 5. All either single-sided or dual-sided 6. Matched in both Channel A and Channel B memory channels 7. Populate symmetrical memory slots (Slot 0 or Slot 1) Note: Configurations that do not match the above conditions will revert to Single Channel mode. The following conditions do not need to be met: 1. Same brand 2. Same timing specifications 3. Same DDR speed Carl
