NOTE: The memory sockets in your computer may be labelled 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 module(s).
