Dell PowerEdge R310 Technical Guide 37

8.2 Slots/Risers

The PowerEdge R310 has 6 DIMM slots for memory and supports:

• 1066/1333 UDIMM or RDIMM (Xeon

only; except L3206)

• 2 channels/up to 2 UDIMM or 3 RDIMM per channel

8.3 Speed

The memory frequency is determined by a variety of inputs:

• Speed of the DIMMs

• Speed supported by the CPU

• Configuration of the DIMMs

The memory speed of each channel depends on the memory configuration:

• For single- or dual-rank memory modules:

– One memory module per channel supports up to 1333MHz

– Two memory modules per channel supports up to 1066MHz

• For quad-rank memory modules:

– One memory module per channel supports up to 1066Mhz

– Two memory modules per channel are limited to 800MHz, 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).

Table 10

shows the memory populations and the maximum frequency achievable for that configuration.
