More memory options are available than ever before with the Dell PowerEdge M820—greater

capacities, higher frequencies, and more flexibility. The M820 supports up to 1.5TB of memory

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.

In addition to supporting existing RDIMM technologies, the M820 supports load reduced DIMMs

(LRDIMMs), which use a buffer to reduce memory loading and allow for greater density, allowing for

the maximum platform memory capacity.

Table 6 lists the memory technologies supported by the M820.
