7.3 DIMM Slots

The T310 planar provides six 72-bit (240-pin) sockets per processor for DIMM memory modules. The
DIMMs are configured as 72 bits wide to provide for ECC, which is performed by the memory
controller in the processor.

7.4 Speed

The PowerEdge T310 supports 1066MT/s and 1333MT/s DDR3 memory. The actual memory frequency
is determined by a variety of inputs:
•
Speed of the DIMMs
•
Speed supported by the processor
•
Configuration of the DIMMs
The memory speed of each channel depends on the memory configuration:
•
For single- or dual-rank memory modules:
o One memory module per channel supports up to 1333MT/s
o Two memory modules per channel supports up to 1066MT/s
•
For quad-rank memory modules:
o One memory module per channel supports up to 1066MT/s
o Two memory modules per channel are limited to 800MT/s, regardless of memory
module speed
If memory modules with different speeds are installed, they will operate at the speed of the slowest
installed memory module(s).
For quad-rank DIMMs mixed with single- or dual-rank DIMMs, the quad-rank DIMM must be installed in
the slot with the white ejection tabs (the first DIMM slot in each channel). There is no requirement
for the order of single- and dual-rank DIMMs.
