Four green DDR5 ECC registered DIMMs with black heat spreaders

A-Tech

A-Tech 128GB (4x32GB) DDR5 5600 ECC RDIMM 1Rx4 Server RAM

SKU CH-V397-N68NF

Four 32 GB DDR5 registered ECC modules at 5600 MHz with CL46 latency and 1.1 V operation

  • Capacity128GB (4 x 32GB)
  • SpeedDDR5 5600 (PC5 44800)
  • CAS LatencyCL46
  • Voltage1.10V
  • ECCYes
  • Buffered/RegisteredRegistered

Capacity 128GB (4 x 32GB)

  • 128 GB total capacity across four 32 GB modules for high-density server workloads
  • DDR5 5600 speed with CL46 latency delivers fast registered memory throughput
  • ECC registered design detects and corrects single-bit errors to protect data integrity

128GB DDR5 5600 ECC RDIMM Kit

This A-Tech kit provides 128GB of DDR5 server memory across four 32GB registered DIMMs. It operates at 5600 MHz with CL46 latency and 1.10V voltage. The modules use single-rank x4 organisation and include on-die ECC for data integrity. They are built for 288-pin DDR5 server and workstation platforms only.

Suits DDR5 registered memory servers

This memory fits servers and workstations that require DDR5 5600 registered ECC RDIMMs. It will not work in desktop or laptop computers that use unbuffered memory. Systems needing load-reduced or higher-rank modules should look at other configurations.

Quad-channel 128GB capacity decision

The four-module 128GB kit fills a quad-channel controller with single-rank 32GB DIMMs. Buyers needing a different total capacity or a different rank structure must choose another kit.

Highlights

  • 128 GB total capacity across four 32 GB modules for high-density server workloads

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit my server's memory slots?

These are 288-pin DDR5 RDIMM modules, the standard form factor for DDR5 server platforms. Verify your system requires registered ECC memory before installing.

What is the correct way to seat all four 32 GB modules in a quad-channel configuration?

Install one module per channel following the motherboard manual's population order; the common error is placing multiple modules in the same channel while leaving others empty.

How do I know when a 32 GB module in this 128 GB kit needs replacement?

ECC corrects single-bit errors and logs uncorrectable ones; replace a module when the system reports recurring corrected errors or an uncorrectable error on that DIMM.
