D3031 (RX200 S6) Technical Manual 21
Features Main memory
3.2 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.
I You will find the descriptions how to install memory modules in the
Options Guide of your server.

– Minimum main memory configuration is 1 DIMM with Independent Channel
Mode.
– It is possible to mix memory modules with different clock rates. The lowest
clock rate will be applied to the system.
