Four green DDR5 RDIMM sticks, bare chips, 288 pins each

A-Tech

A-Tech 128GB (4x32GB) DDR5 5600 ECC RDIMM 2Rx8 server RAM

SKU CH-Z478-A40MZ

A 128GB quad-channel kit of four 32GB DDR5 5600 ECC registered DIMMs with dual-rank x8 organisation and CL46 latency for server and workstation memory upgrades

  • Capacity128GB (4 x 32GB)
  • Type288-Pin DDR5 SDRAM
  • SpeedDDR5 5600 (PC5 44800)
  • CAS LatencyCL46
  • Voltage1.10V
  • ECCYes

Capacity 128GB (4 x 32GB)

  • 128 GB total capacity from four 32 GB modules
  • DDR5 5600 speed with PC5-44800 bandwidth
  • ECC registered design corrects memory errors
  • Dual-rank 2Rx8 organisation increases density
  • 1 V standard DDR5 voltage reduces power

Server-grade DDR5 ECC RDIMM kit

This A-Tech kit supplies 128 GB of DDR5 memory across four 32 GB registered DIMMs. It is built for servers and workstations that require error-correcting code and registered buffering for data integrity.

Upgrade from non-ECC or lower-capacity DDR5

The jump is worth it when workloads demand registered ECC modules at 5600 MHz and the platform supports quad-channel population. Systems limited to unbuffered memory or slower DDR5 speeds cannot use this kit.

128 GB quad-channel capacity at CL46

Four dual-rank 2Rx8 modules deliver high density for virtualisation, database caching and compute-heavy tasks. Headroom ends when the platform caps memory per slot below 32 GB or requires a different registered ECC organisation.

Questions about this item

Does the 288-pin DDR5 RDIMM fit standard server DIMM slots?

Yes, each 32 GB module uses the 288-pin DDR5 RDIMM form factor that matches standard server DIMM sockets.

What is the correct seating order for the quad-channel kit?

Install the four modules in the motherboard's designated quad-channel slots, typically labelled A1, B1, A2, B2, and press until the ejector tabs click.

Will the ECC function require any firmware updates over time?

ECC operates in hardware; no firmware updates are needed for the modules themselves, though platform BIOS updates may improve memory training.
