DIMM Speed

There are two speed options:

  • 1333 MT/s — DIMMs may run at 1.35 volt or 1.5 volt
  • 1600 MT/s — DIMMs may run at 1.35 volt or 1.5 volt
The table below lists the comparison between different DIMM types. For more information on memory, please refer to our memory page at www.dell.com/poweredge/memory

  • Green boxes are defaults for performance/performance per watt
  • White boxes (with lower voltage) can be chosen to save power but run slower
  • White boxes (with higher voltage) can be chosen through custom configuration in the BIOS
