Crucial MTC20F104XS1RC48BR 48GB DDR5 4800 CL40 server RAM

SKU CH-NB5C-W6G69 MPN MTC20F104XS1RC48BR

A 48 GB DDR5 registered ECC DIMM running at 4800 MHz with CL40 latency for server workloads

  • 48 GB capacity supports large server workloads
  • DDR5 technology delivers 4800 MHz transfer speed
  • CL40 latency timing ensures responsive data access
  • Registered ECC design maintains data integrity
  • Single-rank 288-pin DIMM fits standard server slots

48 GB DDR5 registered ECC module

This 48 GB DDR5 DIMM operates at 4800 MHz with CL40 latency and includes registered ECC for data integrity. It uses a 288-pin form factor and a single-rank design suited for server platforms. The module targets administrators who need high-capacity registered memory with error correction. It is not for desktop boards that only accept unbuffered non-ECC DIMMs.

Sustained throughput at 4800 MHz CL40

Under continuous load the module runs at its rated 4800 MHz speed with 40-39-39 timings and registered buffering to stabilise the command bus. ECC corrects single-bit errors on the fly without halting the workload. The single-rank layout keeps electrical loading predictable across populated slots. It is not for workloads that demand lower latency than CL40 or speeds above PC5-38400.

Straightforward 288-pin installation

The DIMM seats in a standard 288-pin DDR5 slot and the registered design requires a platform that explicitly supports registered ECC memory. BIOS must enable ECC and registered mode or the system will not post. Mixing with unbuffered or different-rank modules can prevent boot. It is not for boards that lack registered ECC support in their qualified-vendor lists.

商品問答

How much heat or power does the 48 GB DDR5 4800 module draw during continuous operation?

The registered DDR5 DIMM operates at the standard 4800 MHz speed with CL40 latency; power draw and thermal output follow the DDR5 specification for a 48 GB single-rank module.

What motherboard slot and memory controller features are required to run this 288-pin registered ECC DIMM?

A server board with a 288-pin DDR5 slot that supports registered ECC memory and the PC5-38400 data rate is required.

Will this CL40 registered ECC stick work in a system that currently uses slower DDR5 modules?

The module runs at 4800 MHz with 40-39-39 timings; the memory controller will set the common speed and latency across all installed DIMMs.
