Memory
The PowerEdge MX740c supports up to 24 DIMMs, with up to 3TB of memory and speeds up to 2666MT/s. The MX740c supports
registered (RDIMMs) and load reduced DIMMs (LRDIMMs) which use a buer to reduce memory loading and provide greater
density, allowing for the maximum platform memory capacity. Unbuered DIMMs (UDIMMs) are not supported.
Supported memory
The table below lists the memory technologies supported by the PowerEdge MX740c.
Feature MX740c (DDR4)
DIMM Type RDIMM, NVDIMM-N, LRDIMM

Memory speed
The MX740c supports memory speeds of 2666 MT/s and 2400 MT/s depending on the processor installed. All memory operates at
the same voltage. By default, the speed will be the highest common supported speed between the CPUs and DIMMs. The operating
speed of the memory is also determined by the maximum speed supported by the processor, the speed settings, and the operating
voltage of the system that are in the BIOS.
The table below lists the memory conguration and performance details for MX740c, based on the quantity and type of DIMMs per
memory channel.
