Memory Population Guidelines

When installing memory modules, the DIMM slots should be populated in the following order: P1-DIMMA2, P1-DIMMB2, then P1-DIMMA1, P1-DIMMB1.

Always use DDR3 DIMM modules of the same size, type and speed.

Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed of the slowest DIMM.
