A-Tech 512GB (8x64GB) DDR4 2133 ECC LRDIMM 4Rx4 server RAM

SKU CH-C5NF-0YCG6

Eight 64 GB DDR4 2133 ECC load-reduced DIMMs deliver 512 GB of quad-rank server memory at CL15 and 1.2 V

  • Capacity512GB (8 x 64GB)
  • SpeedDDR4 2133 (PC4 17000)
  • CAS LatencyCL15
  • Voltage1.20V
  • ECCYes

Capacity 512GB (8 x 64GB)

  • 512 GB total capacity supports heavy server workloads with 8 x 64 GB modules
  • DDR4 2133 MHz speed rated at PC4-17000 for fast data throughput
  • ECC Load Reduced DIMM technology corrects errors and reduces electrical load
  • 4Rx4 quad-rank organisation maximises density per 288-pin slot
  • 2 V standard DDR4 voltage keeps power draw low

Server memory kit

This 512GB kit contains eight 64GB DDR4 2133 modules built for servers and workstations that require ECC load-reduced DIMMs. Each module uses a 4Rx4 organisation and runs at the standard 1.2V voltage with CL15 latency. The kit is not compatible with desktop or laptop platforms.

Upgrade path

The kit replaces lower-capacity DDR4 LRDIMM sets or fills empty slots in systems qualified for PC4-17000 registered memory. The jump is worth it when workloads exceed the capacity of smaller kits and the platform supports quad-rank modules per channel. Mixing ranks or speeds can prevent the system from posting.

DDR4 interface limits

DDR4 2133 sets the maximum data rate for this kit and the memory controller must support load-reduced signalling. Quad-rank density reduces the number of modules a channel can accept compared with dual-rank alternatives. Exceeding the platform's ranked-population rules will disable slots or lower the operating speed.

Questions about this item

Will these 288-pin DDR4 LRDIMMs fit my server's memory slots?

Yes — they are standard 288-pin DDR4 DIMMs designed for DDR4 server and workstation slots only, not desktop or laptop boards.

What is the correct way to seat all eight 64 GB quad-rank modules?

Follow your system manual for channel population order; insert each module vertically until the side clips click, ensuring the notch aligns with the slot key.

How do I know when a 4Rx4 module needs replacement?

ECC corrects single-bit errors; if your server logs uncorrectable errors or fails POST on a specific slot, swap that 64 GB module.
