Dell PowerEdge R720 User Manual

24 PowerEdge R720 and R720xd Technical Guide
5 Memory
More memory options are available than ever before with the Dell PowerEdge R720 and R720xd—
greater capacities, higher frequencies, and more flexibility. The R720 and R720xd support up to
768GB of memory (24 DIMMs) and speeds up to 1866MT/s, providing high performance in a variety
of applications. High memory density means there is no compromise when it comes to virtualization.
Increase your uptime and reduce data loss due to Dell’s focus on reliability, availability, and
serviceability (RAS) features. RAS aids in the rapid and accurate diagnosis of faults which require
service, increasing your memory reliability. System uptime is reinforced with RAS features like
memory mirroring, sparing, and many others.
In addition to supporting existing unbuffered DIMMs (UDIMMs) and registered DIMMs (RDIMMs), the
R720 and R720xd support load reduced DIMMs (LRDIMMs), which use a buffer to reduce memory
loading and provide greater density, allowing for the maximum platform memory capacity.

*Although the R720 and R720xd support DIMM speeds lower than 1600MT/s, you can only purchase these systems
with DIMM speeds of 1600MT/s and 1866MT/s on Dell.com/PowerEdge.
