Dell PowerEdge M820 Technical Guide - Page 17

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.
