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.
