5 Memory

More memory options are available than ever before with the Dell PowerEdge M520 — greater

capacities, higher frequencies and more flexibility. The M520 supports up to 384GB of memory

(using 12 DIMMs) and speeds up to 1600MT/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 the Dell focus on reliability, availability and

serviceability (RAS) features. RAS aids in the rapid and accurate diagnosis of faults that require

service, increasing your memory reliability. System uptime is reinforced with RAS features like

memory mirroring, sparing, and many others.
