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.

* 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.
