Memory Module Guidelines

To ensure optimal performance of your computer, observe the following general guidelines when configuring your system memory:
  • Memory modules of different sizes can be mixed (for example, 2 GB and 4 GB). But, all populated channels must have identical configurations.
  • Memory modules must be installed beginning with the first socket.
    • NOTE: Registered DIMMS (R-DIMMs) and Load Reduced DIMMS (LR-DIMMs) cannot be mixed.
  • If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory modules.
    • NOTE: If all DIMMs are 2133, the CPU ordered may run the memory at a slower speed.
