Your system supports unregistered ECC DIMMs (ECC UDIMMs). It supports 1.35 V DDR3L voltage
specifications. The memory bus operating frequency is 1600 MT/s.
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
The following table shows the memory populations and operating frequencies for the supported
configurations.
