IBM System x3630 M4 (E5-2400) 13
The following table shows the characteristics of the supported DIMMs. Table cells highlighted with a gray
background indicate when the combination of DIMM voltage and the number of DIMMs per channel still
allows the DIMMs to operate at a rated speed.

2 DIMMs per channel 1333 MHz 1333 MHz 1600 MHz 1333 MHz 1333 MHz 1600 MHz 800 MHz
* Maximum quantity supported is shown for two processors installed. When one processor is installed, the
maximum quantity supported is a half of what is shown.
** Rated speed is not supported. Memory DIMMs always operate at speeds lower than rated.
