7 Memory
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
The following DIMMs are supported by the PowerEdge R510-4, 8, and 12:
1GB, DDR3 UDIMM, 1066 w/ECC
1GB, DDR3 UDIMM, 1333 w/ECC
1GB, DDR3 RDIMM, 1066 w/ECC
1GB, DDR3 RDIMM, 1333 w/ECC
2GB, DDR3 UDIMM, 1066 w/ECC
2GB, DDR3 UDIMM, 1333 w/ECC
2GB, DDR3 RDIMM, 1066 w/ECC
2GB, DDR3 RDIMM, 1333 w/ECC
4GB, DDR3 UDIMM, 1066 w/ECC
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
16GB, DDR3 RDIMM, 1066 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.
7.4 Sparing
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.
