Dell PowerEdge M820 Systems Manual técnico
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.
