Memory Population Rules
The mainboard supports both single- & dual-channel modes. Install at least one
DIMM module on the slots. You can install either single- or double-sided modules to
meet your own needs. In dual-channel mode, make sure that you install memory
modules of the same type and density on DDR DIMMs “in pairs” -- {DIMM1 &
DIMM2}, {DIMM3 & DIMM4}, {DIMM5 & DIMM6}.
Memory modules can be installed in any combination as follows:
DDR333 DIMM slot population
DDR266 DIMM slot population
