•
* 2nd socket has no DCPMM DIMM.
•
For MM, general NM/FM ratio is between 1:4 and 1:16. Excessive capacity for FM can be
used for AD. (NM = Near Memory; FM = Far Memory)
•
For each individual population, rearrangements between channels are allowed as long
as the resulting population is compliant with the PDG rules for the 82xx/62xx/52xx/42xx
platform.
