Memory Speed; Table 9. Memory Speed Capabilities - Dell PowerEdge R320 Technical Manual

Memory speed

The R320 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 9 lists memory configuration and performance details for the R320 based on the population of
the number and type of DIMMs per memory channel.

*Although the R320 supports DIMM speeds of 800MT/s and 1066MT/s, you can only purchase this system
with DIMM speeds of 1333MT/s and 1600MT/s on Dell.com.
