3.1.1 Independent Channel Configuration
Available slots: 6 per processor
Category
Unbuffered DIMM
(UDIMM)
Registered DIMM
(RDIMM)
NOTE:

Minimum one memory kit per processor must be installed.

It is recommended to install three identical memory kits for triple-channel symmetric memory
configurations to increase memory transfer speed.

When two processors are installed, balance the DIMMs across the two processors.

Mix configurations of UDIMM/RDIMM are not supported.
At least 5 GB of memory is required for VMware ESXi™ 5.5
