Key features of the R515 memory system include the following:
∙Support for up to 32 GB of UDIMM memory (8 x 4 GB)
∙Support for up to 128 GB of DDR3 RDIMM memory (8 x 16 GB) (16 GB DIMMS available Q1 2011)
∙Support for 1333 MHz single- and
∙Support for 1066 MHz
∙Two channels per processor
∙Advanced ECC (Chipkill) mode (x4 RDIMM only)
∙Online spare
∙Parity
∙Low voltage (LV) DIMM support (6 core processor only)
∙Single bit error correction
6.2 DIMMs Supported
The PowerEdge R515 supports DDR3 RDIMMs and UDIMMs. The memory interface uses 1 GB, 2 GB, 4 GB, 8 GB, and 16 GB (available Q1 2011) RDIMMs and 1 GB, 2 GB, and 4 GB UDIMMs. See Table 9.

6.3 DIMM Slots |
| |
The DDR3 memory interface consists of two memory channels per processor socket. Each channel supports up to two RDIMMs for single/dual/quad rank or two UDIMMs. Population order is identified by the silkscreen designator and the System Information Label (SIL) located on the chassis cover.
The following DIMM population rules apply:
∙Support for DDR3 1333 MHz UDIMMs or 1066/1333 MHz RDIMMs
∙2 channels, up to 2 DIMMs per channel
∙Support for 1333 MHz single and
