A-Tech 256GB (8x32GB) DDR4 2933 ECC RDIMM 2Rx4 server RAM

SKU CH-WBHJ-HFN2C

Eight 32 GB DDR4 2933 MHz registered ECC DIMMs provide 256 GB of dual-rank server memory at CL21 and 1.20 V

  • Capacity256GB (8 x 32GB)
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered

Capacity 256GB (8 x 32GB)

  • 256 GB total capacity across eight 32 GB modules
  • DDR4 2933 MHz speed with CL21 latency for responsive server workloads
  • ECC registered RDIMM detects and corrects data errors automatically
  • 2Rx4 dual-rank x4 organisation maximises memory density per channel
  • 20 V standard DDR4 voltage keeps power draw efficient

Server kit for DDR4 workstations

This 256 GB kit contains eight 32 GB modules built for servers and workstations that require DDR4 registered ECC memory. It is not compatible with desktop or laptop computers that use unbuffered DIMMs.

Registered ECC with dual-rank x4 organisation

Each module is a 288-pin DDR4 RDIMM running at 2933 MHz with CL21 latency, 1.20 V operation and 2Rx4 rank configuration. The registered buffer and ECC function only work on platforms designed for registered memory.

Straightforward DIMM installation

Modules seat in standard 288-pin DDR4 slots following the motherboard manual channel guidelines. The most common issue is attempting to use these registered DIMMs in consumer boards that only accept unbuffered memory.

Questions about this item

How does the 2933 MHz speed affect real-world server performance?

The 2933 MHz rating sets the maximum data rate; actual throughput depends on the platform's memory controller, channel population and BIOS settings.

What does PC4-23400 mean for bandwidth limits?

PC4-23400 is the JEDEC designation for DDR4 2933; it indicates the module's rated speed grade, not a guaranteed system-level bandwidth figure.

Will these 288-pin RDIMMs fit my server's DIMM slots?

They require DDR4 RDIMM slots with 288 pins; verify your system manual for supported capacities, ranks and population rules before installing.
