A-Tech 512GB (8x64GB) DDR4 3200 ECC RDIMM 2Rx4 Server RAM

SKU CH-DW93-VS101

Eight registered DDR4 modules deliver 512 GB of ECC server memory at 3200 MHz with CL22 latency

  • Capacity512GB (8 x 64GB)
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.20V

Capacity 512GB (8 x 64GB)

  • 512GB total capacity across 8 modules for large server workloads
  • DDR4 3200 MHz speed with CL22 latency for responsive data access
  • ECC registered RDIMM design detects and corrects memory errors
  • 2Rx4 dual-rank organisation increases memory density per channel
  • 20V standard DDR4 voltage keeps power draw efficient

Server memory kit for enterprise workloads

This 512GB kit contains eight 64GB DDR4 modules built for servers and workstations that require ECC registered memory. It is not compatible with desktop or laptop computers. Each module uses a 288-pin DIMM form factor and operates at the standard 1.2V DDR4 voltage. The dual-rank x4 organisation helps maximise capacity per channel on supported platforms.

Registered ECC with dual-rank x4 organisation

The single specification that decides fitment is the registered ECC RDIMM design combined with a 2Rx4 rank structure. Only systems whose memory controllers explicitly support DDR4 registered ECC modules in a dual-rank x4 configuration will recognise and initialise this kit. Verify the motherboard or server manual for qualified memory lists before purchase.

Sustained throughput at CL22 latency

Under continuous load the modules run at 3200 MHz with a CAS latency of 22 cycles, delivering steady bandwidth for virtualisation, database and compute tasks. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity across all eight populated slots. Error-correcting code detects and corrects single-bit errors in real time, protecting data integrity during extended operations.

Questions about this item

What does 3200 MHz mean for my server once installed?

The kit runs at DDR4 3200 (PC4-25600) with CL22 latency, letting each 64 GB registered ECC module feed data to the CPU at the rated bus speed when the platform is configured for that frequency.

What does the PC4-25600 rating actually limit in practice?

PC4-25600 is the JEDEC designation for DDR4 3200; the memory controller in your server or workstation will not exceed this transfer rate unless it supports a higher DDR4 speed grade.

Will these 288-pin RDIMMs fit my chassis and motherboard slots?

Each module is a standard 288-pin DDR4 RDIMM measuring 64 GB in a 2Rx4 layout; they require server or workstation boards with registered ECC DIMM slots and will not fit desktop or laptop sockets.
