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: The memory sockets in your computer may be labeled differently depending on the hardware
configuration. For example, A1, A2 or 1,2,3.
• If the quad-rank memory modules are mixed with single or dual-rank modules, the quad-rank modules must be
installed in the sockets with the white release levers.
• If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory
modules.
