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

7.2DIMMs Supported

The R210 II supports a minimum of 1 GB upgradeable to 32 GB of RAM using the following DIMM sizes:

	Table 9.	DIMMs Supported
Unbuffered			DRAM Technology
DDR3 1333	1GB DIMM, Single Rank		2Gb
DDR3 1333	2GB DIMM, Single Rank		2Gb
DDR3 1333	4GB DIMM, Dual Rank		2Gb
DDR3 1333	8GB DIMM, Dual Rank		4Gb

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
