A-Tech 512GB (4x128GB) DDR4 3200 ECC LRDIMM 4Rx4 Server RAM

SKU CH-0FKJ-3ZKSW

Four 128 GB DDR4 3200 ECC load-reduced DIMMs deliver 512 GB of quad-rank server memory at CL22 and 1.2 V

  • Total capacity512 GB (4 × 128 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor Brand Chipset
  • CAS latencyCL22
  • Rated voltage1.2 V

Capacity 512GB (4 x 128GB)

  • 512 GB total capacity from four 128 GB modules
  • DDR4 3200 speed with CL22 latency for fast data access
  • ECC Load Reduced DIMM detects and corrects memory errors
  • Quad-rank 4Rx4 organisation maximises density per slot
  • 2 V standard DDR4 voltage keeps power draw low

Server Memory Kit

This A-Tech kit supplies 512GB of DDR4 server memory across four 128GB LRDIMM modules. Each module runs at 3200MHz with a CAS latency of 22 and operates at the standard 1.20V. The load-reduced design uses a 4Rx4 quad-rank x4 organisation and includes on-die ECC for data integrity in enterprise workloads.

Suited For Multi-Channel Servers

The quad-channel kit targets administrators expanding memory in compatible DDR4 servers or workstations that accept 288-pin LRDIMMs. It will not function in desktop or laptop platforms, nor in systems that require registered RDIMMs or unbuffered UDIMMs. Buyers needing smaller capacities or non-ECC memory should consider other configurations.

Verify Platform Compatibility

Confirm that your motherboard or server chassis supports DDR4 3200 LRDIMMs with a 4Rx4 rank structure and quad-channel population rules. Check the vendor memory-qualified list for the exact part number and ensure the BIOS revision recognises 128GB load-reduced modules. Physical clearance for 288-pin DIMM slots is also required.

Questions about this item

Does my server motherboard need 288-pin DDR4 LRDIMM slots to use this 512GB kit?

Yes, the kit uses 288-pin DDR4 Load Reduced DIMMs that only fit server or workstation boards with LRDIMM support.

Can I add these 4Rx4 modules to a system that already runs 2Rx4 DDR4 3200 ECC RDIMMs?

No, Load Reduced and Registered DIMMs cannot be mixed; the motherboard must support LRDIMM and all slots must use the same module type.

How can I confirm the 512GB kit is running at 3200 MHz with CL22 after installation?

Check the BIOS memory information or a tool such as dmidecode; it should show each 128GB module at 3200 MT/s, CAS 22, 1.20V, and ECC LRDIMM type.
