DIMM Population Order

The maximum combined memory allowed in the 12 DIMM slots controlled by any one CPU is
768 GB. To populate the 12 DIMM slots with more than 768 GB of combined memory, you
must use a high-memory CPU that has a PID that ends with an "M", for example,
UCS-CPU-6134M.
All DIMMs must be DDR4 DIMMs that support ECC. Non-buffered UDIMMs and non-ECC DIMMs
are not supported.
Memory mirroring reduces the amount of memory available by 50 percent because only one
of the two populated channels provides data. When memory mirroring is enabled, you must
install DIMMs in even numbers of channels.
NVIDIA M-Series GPUs can support only less than 1 TB memory in the server.
NVIDIA P-Series, V-series, and T-series GPUs can support 1 TB or more memory in the server.
AMD FirePro S7150 X2 GPUs can support only less than 1 TB memory in the server.
