OWC 1TB (4x256GB) DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Load Reduced LRDIMM memory upgrade kit

SKU CH-4DJ8-MT02V

Four 256 GB DDR4 3200 CL22 ECC load-reduced DIMMs totalling 1 TB for Supermicro H12SSL and H12SSW servers

Capacity 1TB (4 x 256GB)

  • 1 TB capacity with four 256 GB modules
  • DDR4 3200 MHz CL22 for high-throughput server workloads
  • ECC load-reduced design protects data integrity in multi-socket systems
  • JEDEC-standard 1.2 V operation ensures broad platform compatibility
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz speeds

Server-grade ECC LRDIMM kit

This kit provides 1TB of DDR4 ECC Load Reduced memory across four 256GB modules. It is built for Supermicro H12SSL and H12SSW motherboards in workstation and server roles. Standard desktop systems cannot use this memory type, and it must not be mixed with unbuffered or registered ECC DIMMs.

Sustained 3200MHz operation with backward steps

Each module runs at PC4-25600 3200MHz CL22 under continuous server workloads. The JEDEC-standard design maintains rated speed without throttling during extended compute tasks. Backward compatibility allows operation at 2133MHz, 2400MHz, 2666MHz and 2933MHz when the platform requires a lower data rate.

288-pin LRDIMM form factor for dense slots

The 288-pin Load Reduced DIMM format fits the target Supermicro boards and reduces electrical load on the memory controller. ECC circuitry corrects single-bit errors to protect data integrity in NAS and virtualization environments. Modules operate at 1.2V and meet JEDEC and RoHS compliance for warranty-safe deployment.

Questions about this item

How much heat and power will four 256 GB DDR4 3200 CL22 LRDIMMs add to a server running 24/7?

Each module operates at 1.2 V with standard DDR4 power characteristics; total draw scales with all four DIMMs populated and sustained 3200 MT/s workloads.

Which motherboards must I already own for this 1 TB kit to function?

The kit is validated for Supermicro H12SSL-CT, H12SSL-NT, H12SSW-iNR and H12SSW-NTR motherboards that accept DDR4 ECC load-reduced DIMMs.

Will these 3200 MHz CL22 modules down-clock reliably beside older 2133 MHz DDR4 DIMMs I keep installed?

JEDEC backward compatibility lets the kit run at 2133, 2400, 2666 or 2933 MT/s when mixed with slower DDR4 ECC load-reduced memory.
