Memory configurations

The M620 server supports flexible memory configurations ranging from capacities of 4GB to 768GB
(using 32GB DIMMs), and up to 12 DIMMs per processor (up to 24 DIMMs in a dual-processor
configuration). Each processor has four memory channels, with each channel supporting up to
three DIMMs.

Memory capacity options

The M620 is available in the following memory capacity options:

24-DIMM capacity: uses a 57mm heatsink and is recommended for use with processors of 95W
or less

20-DIMM capacity: uses a 77mm heatsink for cooling efficiency and is recommended for use
with 115W and 130W processors

16-DIMM capacity: uses a 97mm heatsink to support the higher ambient temperatures of Dell
