5 Memory

More memory options are available than ever before with the Dell PowerEdge T620 — greater
capacities, higher frequencies,= and more flexibility. The T620 supports up to 768GB of memory
(24 DIMMs) and speeds up to 1866MT/s, providing high performance in a variety of applications. And,
high memory density means no compromise when it comes to virtualization.
Dell's focus on reliability, availability and serviceability (RAS) features can help you increase your
uptime and reduce data loss. 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
T620 supports 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 T620 supports 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.
