PowerEdge R415 Technical Guide
6 Memory
6.1 Overview
The PowerEdge R415 uses DDR3 memory, providing a high-performance, high-speed memory interface
capable of low-latency response and high throughput.
Key features of the R415 memory system include:
 Support for up to 128 GB of memory (8 x 16 GB RDIMMS) (16 GB DIMMS available Q1 2011)
 Two channels per processor
 Registered ECC DDR3 DIMMs or Unbuffered ECC DDDR3 DIMMs
 DDR3 speeds of 1066/1333 MHz
 Single rank, dual rank, and quad rank DIMMs
 Single bit error correction
 Advanced ECC (Chipkill)
 Online spare
 Parity
 Low voltage (LV) DIMM support (6-core processor only)
6.2 DIMMs Supported
The PowerEdge R415 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 dual-rank DIMMs, 1066 MHz quad-rank DIMMs
