Crucial MTC20F1045S1RC48BR 32GB DDR5-4800 CL40 server RAM

SKU CH-WXDV-3CTVR MPN MTC20F1045S1RC48BR

Single-rank 32 GB DDR5 server module at 4800 MHz, CL40, 1.10 V registered

  • 32 GB capacity supports large server workloads
  • DDR5-4800 speed delivers high data throughput
  • Single-rank design enables efficient memory access
  • CL40 latency provides responsive operation
  • 10 V voltage reduces power consumption

32 GB DDR5-4800 Registered Server Memory

This single 32 GB DDR5 module operates at 4800 MHz with a CL40 latency and a 1.10 V operating voltage. It uses registered signal processing to support stable operation in multi-module server configurations. The single-rank design helps maintain signal integrity on dense memory channels.

Capacity and headroom for virtualised workloads

The 32 GB capacity suits virtualisation hosts and database nodes that need moderate density per slot. Single-rank organisation allows higher total channel counts before reaching electrical limits. Registered buffering adds latency overhead that can reduce throughput in latency-sensitive single-threaded applications.

Registered signal processing and single-rank layout

Registered buffering enables the memory controller to drive larger arrays without signal degradation. The single-rank layout reduces electrical load per channel compared to dual-rank alternatives. No bundled software or accessories are included with this bare module.

Questions about this item

Will this DDR5-4800 CL40 registered module fit the DDR5 slots on my current server board?

This module uses the DDR5 form factor and operates at 4800 MHz with a CL40 latency. It requires a motherboard that supports DDR5 registered memory at 1.10 V.

How can I confirm the module is running at the correct 4800 MHz speed and CL40 timings after installation?

Check the system BIOS or a utility such as CPU-Z; they should report 4800 MHz (PC5-38400), CL40, 1.10 V and registered single-rank operation.

What is included in the box and do I need any extra parts to install this 32 GB stick?

The box contains one 32 GB DDR5-4800 registered DIMM. No additional components are required if your server has a free DDR5 RDIMM slot.
