Micron Technology, Inc. MTC40F204WS1RC64BB2 96GB DDR5-6400 CL46 ECC Registered Dual Rank Server RAM

SKU CH-GBT6-DC36H MPN MTC40F204WS1RC64BB2

96 GB DDR5-6400 registered ECC module with dual-rank density and CL46 latency for server workloads

  • 96 GB capacity enables large in-memory workloads
  • DDR5 6400 MT/s data rate accelerates throughput
  • Registered ECC protects data integrity in servers
  • Dual-rank organisation increases memory density per slot
  • 1 V operation reduces power draw per module

Purpose-built capacity

This 96GB DDR5-6400 module targets servers and workstations that require registered ECC memory for data integrity. The dual-rank design and 1.1V operating voltage suit high-density configurations in multi-socket platforms.

Deciding specification

The single figure that determines fit is the registered ECC interface combined with a CL46 latency at 6400MHz data rate. Systems expecting unbuffered non-ECC DIMMs or a different CAS timing will not accept this module.

Bundled impact

No accessories, cables or software licences are included with the memory module. Installation depends entirely on the host platform's memory-controller support for PC5-51200 registered dual-rank DIMMs.

Questions about this item

What does the 6400 MT/s rating mean for actual throughput in a server?

The module runs at 6400 MT/s with a PC5-51200 data rate, giving up to 51200 MB/s peak bandwidth per channel while the registered ECC design keeps data integrity intact.

How does the DDR5 interface and registered ECC design affect usable speed?

DDR5 at 6400 MT/s with registered ECC adds a clock cycle for command buffering, so the effective throughput stays at the rated PC5-51200 level while correcting single-bit errors on the fly.

What physical slot and clearance does this 288-pin DIMM need?

It fits a standard 288-pin DDR5 DIMM socket, operates at 1.1 V, and the dual-rank 96 GB layout uses the normal module height for server boards.
