Main memory

The 12 slots (6 for each CPU) for main memory are designed for RDIMM

(registered DIMM, capacities: 2, 4, 8 and 16 GB) as well as for UDIMM

(unbuffered DIMM, capacity 2 GB) memory modules. The maximum main

memory is for installing UDIMM memory modules 24 GB (12x 2 GB), for

installing RDIMM memory modules 192 GB (12x 16 GB). Mixing both types of

memory modules is not supported and leads to an error message.

When using Westmere-EP processors LV-DIMMs (low voltage DIMMs) can be

used.

ECC with memory scrubbing and with the Single Device Data Correction

(SDDC) function (only with RDIMMs) is supported.

You will find the descriptions how to install memory modules in the

Options Guide of your server.
