7 Memory
7.1 Overview
The Dell™ PowerEdge™ T710 uses DDR3 memory providing a high performance, high-speed memory
interface capable of low latency response and high throughput. T710 supports Registered ECC DDR3
DIMMs (RDIMM) or Unbuffered ECC DDR3 DIMMs (UDIMM).
The DDR3 memory interface consists of three channels. The maximum number of supported DIMMs is
dependent on the type of DIMM used.
Maximum Configuration by DIMM Type Table 13.
Single- or dual-rank RDIMM
3 per channel per processor (18 total)
2 per channel per processor (12 total)
Single- or dual-rank UDIMM
2 per channel per processor (12 total)
Key features of the T710 memory system include:
Registered (RDIMM) and Unbuffered (UDIMM) DDR3 technology
Each channel carries 64 data and eight ECC bits
Support for up to 192 GB of RDIMM memory (twelve 16 GB RDIMMs)
Support for up to 24 GB of UDIMM memory (twelve 2 GB UDIMMs)
Support for 1333 MT/s single- and dual-rank DIMMs
Support for 1066 MT/s quad-rank DIMMs
Support for 1.35V low voltage (LV) DIMMs
Single DIMM configuration with DIMM at socket DIMM A1
Support ODT (On Die Termination)
