7.1 Overview

Please carefully review this entire section

Features of the PowerEdge R510 memory include:

•3 channels per processor

•Support for registered ECC DDR3 DIMMs or Unbuffered ECC DDDR3 DIMMs.

•DDR3 speeds of 800/1066/1333 supported (Max memory clock speed support is pending on the processors used. Refer to table in Section 8C.)

•

•

•

8 (2/1/1) DIMM sockets (128GB Maximum capacity) Support for Single Rank, Dual Rank, and Quad Rank DIMMs

Intel Xeon processor 5600 series also supports Low Voltage DIMMs and sparing feature

7.2 DIMMs Supported

∙4GB, DDR3 UDIMM, 1333 w/ECC

∙4GB, DDR3 RDIMM, 1066 w/ECC

∙4GB, DDR3 RDIMM, 1333 w/ECC

The PowerEdge R510-8 and 12 also support:

∙8GB, DDR3 RDIMM, 1066 w/ECC

∙8GB, DDR3 RDIMM, 1333 w/ECC

7.3 Mirroring

In mirroring mode, the PowerEdge R510 has identical memory configuration in Channel_0 and Channel_1; it does not have memory in Channel_3. When mirroring mode is enabled, usable memory capacity is half of the physical memory installed.

7.4Sparing

Intel has added sparing back with Xeon processor 5600 series. In sparing mode, you must have identical memory in Channel_0, Channel_1 and Channel_2. For the R510, memories are installed in A1, A2 and A3 to enable the sparing mode. With sparing mode is enabled, usable memory capacity is 2/3 of the physical memory installed.
