SAMSUNG M393A8G40D40-CRB 64GB DDR4 memory

SKU CH-BR2P-3N68V

A 64 GB DDR4 module running at 2133 MT/s for high-capacity server memory upgrades

  • Capacity64GB (4 x 16GB)
  • 64 GB single module simplifies high-capacity upgrades
  • DDR4 SDRAM technology supports PC4-2133P platform speeds
  • 16 GB per rank enables efficient 2S4RX4 organisation
  • Samsung M393A8G40D40-CRB part ensures exact compatibility
  • New condition delivers full factory reliability

64 GB DDR4 server module

This is a single 64 GB DDR4 SDRAM module built for servers and workstations that need high memory density per slot. It suits administrators who run virtualisation hosts, in-memory databases or large compute clusters.

Sustained load behaviour

The module operates at the PC4-2133P rated speed with a 2S4RX4 organisation designed for stable throughput during long-running workloads. Error-correcting code support helps maintain data integrity when the system stays under continuous pressure.

DDR4 interface limits

DDR4 bandwidth and latency are bounded by the 2133 MT/s transfer rate and the registered DIMM protocol used here. Systems that require higher memory clocks or greater per-channel capacity will need a newer memory standard.

Questions about this item

How much power does the 64GB DDR4 module draw under sustained load?

The module follows the standard DDR4 voltage specification, so typical operating power stays within the JEDEC limits for this density.

What motherboard slot and chipset are required to run this 64GB DDR4 stick?

A DDR4 DIMM slot with a memory controller that supports 64GB single-rank modules and the PC4-2133 data rate is needed.

Will this 64GB DDR4 module work alongside my existing 16GB DDR4 sticks at 2133 MT/s?

Yes, the motherboard will clock all installed DDR4 memory to the lowest common speed, so the 64GB module will run at 2133 MT/s with your current sticks.
