Specifications

For more information on memory configuration, see the
Dell PowerEdge T620 Owner’s Manual
on
Support.Dell.com/Manuals.
The T620 supports memory speeds of 1600MT/s, 1333MT/s, 1066MT/s, and 800MT/s depending on
the DIMM types installed and the configuration. All memory on all processors and channels run at
the same speed and voltage. By default, the systems run at the highest speed for the channel with
the lowest DIMM voltage and speed. The operating speed of the memory is also determined by the
maximum speed supported by the processor, the speed settings in the BIOS, and the operating
voltage of the system.
Table 10 lists memory configuration and performance details for the T620 based on the population
of the number and type of DIMMs per memory channel.
