What Is the Samsung M386ABG40M5B-CYF 256GB DDR4-2933 LRDIMM?

The Samsung M386ABG40M5B-CYF is a genuine 256GB DDR4 server memory module. This is one of the highest capacities in standard DDR4. It runs at 2933MHz. It follows the PC4-23400 standard. It uses ECC Load Reduced design with an octal-rank, x4 layout at 1.2V.

Load Reduced memory uses a data buffer chip instead of a direct register. This lets a server pack maximum total memory into its channels. The module carries a CL21 latency rating.

Which Servers Use This Module?

This module fits enterprise servers built for top-density DDR4-2933 Load Reduced memory. Many Dell PowerEdge, HP ProLiant, and Lenovo ThinkSystem models support 256GB LRDIMM. Always check your exact model first.

Is This Module New or Refurbished?

This module is refurbished, not new. Each one is cleaned and tested. This confirms it works before it gets listed. The chips are genuine Samsung dies. A 30-day warranty covers every order.

Best Uses for This Memory Module

This module suits a server with top density needs using LRDIMM. Massive databases and large virtualization hosts benefit most. It also replaces a failed 256GB module with a matched, tested part.

Common Questions

Is this the same as Samsung's M393ABG40M5B-CYF part number?

No. That part uses 3DS RDIMM construction instead of a data buffer chip. Both reach 256GB, but through different technologies.

Can this LRDIMM be mixed with standard RDIMM in the same server?

No. Most servers require all installed modules to be the same type, either all RDIMM or all LRDIMM, within a channel.
