PowerEdge T310 Technical Guide

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 with 32GB maximum capacity

• Support for unbuffered ECC DDR3 DIMMs (UDIMM) or registered ECC DDR DIMMs (RDIMM)

• DDR3 speeds of 1066MT/s and 1333MT/s

• 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. The following DIMMs are

supported by the PowerEdge T310:

• 1GB, DDR3 UDIMM, 1066 with ECC

• 1GB, DDR3 UDIMM, 1333 with ECC

• 1GB, DDR3 RDIMM, 1066 with ECC

• 1GB, DDR3 RDIMM, 1333 with ECC

• 2GB, DDR3 UDIMM, 1066 with ECC

• 2GB, DDR3 UDIMM, 1333 with ECC

• 2GB, DDR3 RDIMM, 1066 with ECC

• 2GB, DDR3 RDIMM, 1333 with ECC

• 4GB, DDR3 UDIMM, 1066 with ECC

• 4GB, DDR3 UDIMM, 1333 with ECC

• 4GB, DDR3 RDIMM, 1066 with ECC

• 4GB, DDR3 RDIMM, 1333 with ECC

• 8GB, DDR3 RDIMM, 1066 with ECC

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
