System memory

Your system supports DDR4 ECC unbuffered DIMMs (UDIMMs).
NOTE: MT/s indicates memory module speed in Mega Transfers per second.
Memory bus operating frequency can be 2133 MT/s, 1866 MT/s, or 1600 MT/s depending on the
following factors:
• System profile selected (for example, Performance Optimized, Custom, or Dense Configuration
Optimized)
• Maximum supported memory module frequency of the processors
The system contains four memory sockets — two sets of 2–sockets each. Each 2–socket set is organized
into one channel. In each 2-socket set, the first socket release lever is marked white and the second
socket release lever is marked black.

Memory channels are organized as follows:
Processor 1
channel 0: memory sockets A1 and A3
channel 1: memory sockets A2 and A4
The following table shows the memory populations and operating frequencies for the supported
configurations:
