7 Memory

The Dell™ PowerEdge™ T310 supports DDR3 memory, providing a high performance, high-speed
memory interface capable of low latency response and high throughput. Key features of the T310
memory system include:
•
2 channels per processor
•
6 DIMM sockets
•
Support for unbuffered ECC DDR3 DIMMs (UDIMM) or registered ECC DDR DIMMs (RDIMM)
UDIMM maximum capacity of 32 GB (4 x 8 GB UDIMMs)
o
RDIMM maximum capacity of 24 GB (6 x 4 GB RDIMMs)
o
•
DDR3 speeds of 1066 MHz and 1333 MHz
•
Support for single-, dual-, and quad-rank DIMMs

7.1 DIMMs Supported

The DDR3 memory interface consists of two channels with up to two RDIMMs or UDIMMs per channel
for single or dual rank and up to two RDIMMs per channel for quad rank.

7.2 DIMM Population Rules

The following DIMM population rules apply:
•
If DIMMs of different speeds are mixed, all channels will operate at the fastest common
frequency.
•
RDIMMs and UDIMMs cannot be mixed.
•
Mixing of ECC and non-ECC UDIMMs will force the system to function in non-ECC mode.
•
Mixing quad-rank RDIMMs in one channel and 3DPC in another channel with the same
processor socket is not supported.
•
DIMMs must be installed in each channel starting with the DIMM slot farthest from the
processor (slot 0)
•
For each processor, Channel 0 supports up to two DIMMs and Channel 1 and 2 support one
DIMM each

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 1066 MHz and 1333 MHz 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
