Two green 288-pin DDR4 LRDIMM modules in anti-static tray

OWC

OWC 512GB (2x256GB) DDR4 2933 PC4-23400 CL21 8Rx4 288-pin 1.2V ECC Load Reduced LRDIMM memory upgrade

SKU CH-T8QJ-TXBX8

512GB DDR4 ECC load-reduced DIMM kit for Supermicro H12SST-PS servers, running at 2933MHz CL21 with backward compatibility down to 2133MHz

Capacity 512GB (2 x 256GB)

  • 512 GB total capacity from two 256 GB modules
  • DDR4 2933 MHz PC4-23400 CL21 for server workloads
  • ECC load-reduced design protects data integrity
  • 2 V operation reduces power draw
  • Backward compatible with 2133, 2400 and 2666 MHz systems

512GB DDR4 LRDIMM kit for Supermicro H12SST-PS

This kit provides 512GB of DDR4 ECC Load Reduced memory across two 256GB modules. It is built for servers, workstations and NAS systems that require registered LRDIMM technology. Standard desktop computers cannot use this memory type. It also cannot be mixed with unbuffered or standard ECC registered modules.

Sustained 2933MHz operation with CL21 latency

The modules run at PC4-23400 2933MHz with a CL21 timing profile at 1.2V. Backward compatibility covers 2133MHz, 2400MHz and 2666MHz bus speeds for flexible deployment. JEDEC-standard compliance ensures stable throughput under continuous server workloads. Error-correcting code protects data integrity during extended operations.

288-pin LRDIMM form factor for dense configurations

Each 256GB module uses an 8Rx4 organisation within the 288-pin load-reduced layout. This design reduces electrical load on the memory bus when populating multiple slots. The kit is validated specifically for the Supermicro H12SST-PS motherboard. ROHS-compliant construction meets environmental standards for data-centre deployment.

Points forts

Questions sur cet article

How much power does the 1.2V LRDIMM kit draw under sustained load?

Each module operates at 1.2V; total power draw depends on the server's memory controller and workload, so consult the platform's specifications for exact figures.

What motherboard and CPU combination is required to run this 288-pin ECC load-reduced memory?

The kit is validated for the Supermicro H12SST-PS motherboard and requires a processor that supports DDR4-2933 LRDIMM with 8Rx4 organisation.

Will these 2933MHz modules downclock automatically if I keep my existing 2133MHz DIMMs in the same system?

The modules are backward compatible with 2133MHz, 2400MHz and 2666MHz speeds, but LRDIMM cannot be mixed with unbuffered or registered ECC DIMMs.
