System memory

Your system supports DDR4 unbuffered ECC DIMMs and Non-ECC DIMMs.

CAUTION: Dell recommends you to use ECC DIMMs to minimize the risk of uncorrectable system error, data loss and/or silent data corruption. Non-ECC DIMM is not used for mission-critical applications.

NOTE: Non-ECC DIMMs are supported only in selected countries, for more information contact your sales representative.

System performance varies depending on:

Maximum frequency of the DIMMs
Number of DIMMs populated per channel
System profile selected (for example, Performance Optimized, Custom, or Dense Configuration Optimized).

The system contains four memory sockets — two sets of 2-sockets each. Each 2-socket set is organized into one channel. In each socket set, the first socket release lever is marked white and the second socket release lever is marked black.

The figure shows system memory locations. — Figure 1. Memory socket locations on the system board

Memory channels are organized as follows:

Channel 0: memory sockets 1 and 3
Channel 1: memory sockets 2 and 4

The following table shows the memory population and operating frequencies for the supported configurations.

Table 1. Supported memory This table lists the supported memory configurations.
Memory module type	Memory modules populated per channel	Operating frequency (in MT/s)	Maximum memory module rank per channel	Operating voltage
UDIMM	Two	2133, 2400, 2666	Four	1.2 V

NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
