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.
