5 Memory

More memory options are available than ever before with the Dell PowerEdge M420 — greater

capacities, higher frequencies and more flexibility. The M420 supports up to 192GB of memory

using up to six DIMMs in a dual-processor configuration, 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 Dell's 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.

The M420 supports unbuffered DIMM (UDIMM) and registered DIMM (RDIMM) technology.
