21 PowerEdge R630 Technical Guide
5 Memory
The Dell PowerEdge R630 supports up to 768GB of memory (24 DIMMs) and speeds up to 2133MT/s,
providing high performance in a variety of applications. High memory density means there is no
compromise when it comes to virtualization.
The R630 supports both registered DIMMs (RDIMM) and load-reduced DIMMs (LRDIMMs), which use
a buffer to reduce memory loading and provide greater density, allowing for the maximum platform
memory capacity. Unbuffered DIMMs (UDIMMs) are not supported.
