Specifications

More memory options are available than ever before with the Dell™ PowerEdge™ R620—greater

capacities, higher frequencies, and more flexibility. The R620 supports up to 768GB of memory

(24 DIMMs) and speeds up to 1600 MT/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 (UDIMM) and registered DIMMs (RDIMM), the

R620 supports load reduced DIMMs (LRDIMM), which use a buffer to reduce memory loading and

provide greater density, allowing for the maximum platform memory capacity.

Table 8 lists the memory technologies supported by the R620.
