A-Tech 48GB DDR5-5600 ECC UDIMM 2Rx8 1.1V 288-Pin server RAM

SKU CH-K3XT-YSWSZ

48GB DDR5-5600 ECC UDIMM module with 2Rx8 dual-rank organisation for server and workstation memory expansion

  • Total capacity48 GB
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor Brand Chipset
  • CAS latency40
  • Rated voltage1.1 V
  • Buffer typeUnbuffered

Capacity 48GB

  • 48 GB capacity handles large workloads and heavy multitasking
  • ECC UDIMM detects and corrects single-bit errors for data integrity
  • DDR5-5600 speed delivers 44800 MT/s bandwidth for faster throughput
  • Dual-rank 2Rx8 organisation increases memory density per channel
  • 1 V standard voltage reduces power draw per module

Server memory upgrade

This 48GB DDR5-5600 ECC UDIMM module targets servers and workstations that require error-correcting unbuffered memory. It adds capacity for virtualization, database or compute workloads where data integrity matters.

Compatibility checklist

Verify that your platform supports DDR5 ECC UDIMM modules at 5600 MT/s with a 2Rx8 dual-rank x8 organization. The system must accept 288-pin DIMMs operating at 1.10V and provide appropriate slot population rules for the intended channel configuration.

Sustained workload behaviour

ECC corrects single-bit errors on the fly during continuous operation, reducing silent data corruption risk. Dual-rank density and standard DDR5 voltage maintain stable throughput across extended compute sessions without relying on burst-only performance.

Questions about this item

Does the 48GB DDR5-5600 ECC UDIMM come alone or with extra parts?

The package contains the single 48GB module only; no heat spreader, cables, tools or additional memory sticks are included.

How do I know if the 2Rx8 dual-rank 48GB stick is the right capacity for my server?

Check your system manual for maximum supported capacity per slot and total DDR5 ECC UDIMM limit, then match the 48GB dual-rank module to those specifications.

What does the DDR5-5600 (PC5-44800) speed rating deliver in an actual server?

The module runs at 5600 MT/s with CL40 latency at the standard 1.10V, providing the rated bandwidth when the platform’s memory controller is configured for DDR5-5600 operation.
