A-Tech 256GB (4x64GB) DDR4 2933 ECC RDIMM 2Rx4 Server RAM

SKU CH-HJF4-VKP5S

A 256 GB quad-channel kit of four 64 GB DDR4 2933 ECC registered DIMMs with CL21 latency and 1.2 V operation for compatible servers and workstations

  • Capacity256GB (4 x 64GB)
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered

Capacity 256GB (4 x 64GB)

  • 256 GB quad-channel kit expands server memory capacity for heavy workloads
  • DDR4 2933 MHz speed accelerates data throughput in compatible platforms
  • ECC registered design detects and corrects single-bit errors to protect data integrity
  • Dual-rank 2Rx4 organisation increases memory density per channel
  • 20 V standard voltage maintains efficient power draw across all modules

Server Memory Kit

This A-Tech kit supplies 256 GB of DDR4 ECC registered memory in four 64 GB modules for servers and workstations that require registered DIMMs. It is not compatible with desktop or laptop computers that use unbuffered memory.

Installation Notes

The 288-pin DIMMs install in standard DDR4 server slots and operate at 1.2 V. Follow the system manual for correct channel population and seating order; mixing registered and unbuffered modules will prevent the system from booting.

Sustained Load Behaviour

ECC error correction and registered buffering maintain data integrity during continuous workloads such as virtualisation or database processing. The CL21 latency at 2933 MHz provides stable throughput without the variability seen in consumer modules under prolonged stress.

Questions sur cet article

How do I confirm the 256GB kit is running at 2933 MHz with ECC active after installation?

Enter the system BIOS or UEFI and verify the memory speed reads 2933 MHz (PC4-23400) and that ECC is reported as enabled; the modules operate at 1.20 V with CL21 latency.

What exactly ships in the box and do I need any extra parts to install the four 64GB modules?

The box contains four 64GB DDR4 2933 MHz ECC RDIMM modules (288-pin, 2Rx4); no additional components are required if your server or workstation has four available DDR4 RDIMM slots.

Should I choose this 256GB quad-channel kit or a different capacity for my DDR4 server?

Select this 256GB (4×64GB) kit when your platform supports quad-channel DDR4 2933 registered ECC memory and you need the full capacity; otherwise choose a smaller kit that matches your slot count and maximum supported memory.
