7.1 Overview

The R210 II supports DDR3 memory, providing a high performance, high speed memory interface capable of low latency response and high throughput. For the Intel processor-based R210 II, up to 4 total DIMMs are supported. Additional specifics regarding memory include:

2 Gb DRAM technology

2 channels per processor

Unbuffered (UDIMM) ECC DDR3 DIMMs

DDR3 speeds of 1066/1333 (UDIMM only)

Single- and dual-rank UDIMMs (all channels in a system run at the fastest common frequency)

Support for up to 32 GB UDIMM memory (4 x 8 GB UDIMMs)

Single DIMM configuration only with DIMM in socket A1

No support for quad-rank DIMMs

No RDIMM support

Low-voltage (LV) DIMM supported @ 3.5V only

Non-ECC DIMMs not supported

7.3 DIMM Slots

The PowerEdge R210 II has 4 DIMM slots for memory, supporting up to 2 DIMMs per channel.

7.4 Speed

The 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-rank memory modules

o One memory module per channel supports up to 1333 MHz o Two memory modules per channel supports up to 1333 MHz
