Crucial MTC40F204WS1RC56BR 96GB DDR5-5600 CL46 server RAM

SKU CH-82A8-09M4J MPN MTC40F204WS1RC56BR

A 96 GB DDR5 registered DIMM running at 5600 MHz with CL46 latency for server workloads

  • 96 GB capacity supports large-scale virtualisation workloads
  • DDR5 technology delivers 5600 MT/s data rate for high throughput
  • CL46 latency timing optimises response in registered configurations
  • Registered DIMM architecture enhances signal integrity for server stability
  • 288-pin form factor fits standard DDR5 server memory slots

96GB DDR5-5600 registered DIMM

This Crucial module delivers 96GB of DDR5 SDRAM at 5600 MHz with CL46 latency. The 288-pin DIMM uses PC5-44800 signalling and registered buffering to support high-capacity server configurations. It is built for enterprise workloads that demand large memory footprints and data integrity.

Suited for memory-heavy servers.

The registered design and ECC capability target multi-socket servers running virtualisation, databases or large-scale analytics. Workstations and consumer motherboards that require unbuffered DIMMs cannot use this module. Buyers who need non-ECC memory or lower capacities should select a different product.

Straightforward DIMM installation.

Installation follows the standard 288-pin DIMM procedure: align the key notch, press firmly until the retention clips engage, and confirm seating. The most common issue is attempting to install registered memory on platforms that only accept unbuffered DIMMs, which prevents the system from posting. Always check the motherboard or server documentation for registered DDR5 support before purchasing.

Questions about this item

Does my motherboard need 288-pin DDR5 slots to use this 96GB module?

Yes, the module uses the standard 288-pin DDR5 DIMM form factor, so the board must provide DDR5 slots with that pin count.

Will this registered DDR5 DIMM work in a system that already has unbuffered DDR5 memory installed?

No, registered and unbuffered DDR5 modules cannot be mixed; the motherboard requires one type or the other across all populated slots.

How can I verify the module is running at 5600 MHz with CL46 latency after installation?

Check the memory speed and timings in the system BIOS or use a hardware information utility to confirm DDR5-5600 and CL46 values.
