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

OWC

OWC 512GB (2x256GB) DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Load Reduced LRDIMM memory upgrade kit

SKU CH-94YH-1N5WX

512 GB DDR4 3200 ECC load-reduced LRDIMM kit with two 256 GB modules for compatible Supermicro server boards

Capacity 512GB (2 x 256GB)

  • 512GB total capacity for demanding server workloads
  • 2x256GB DDR4 3200 CL22 ECC Load Reduced modules
  • JEDEC and RoHS compliant for warranty-safe upgrades
  • Backward compatible with 2133, 2400, 2666, 2933MHz systems
  • Designed for Supermicro H12SSL and H12SSW motherboards

Server-grade memory kit

This OWC kit provides 512GB of DDR4 ECC Load Reduced memory across two 256GB modules. It is built for Supermicro motherboards H12SSL-CT, H12SSL-NT, H12SSW-iNR and H12SSW-NTR in server, workstation or NAS deployments.

Verify platform compatibility

Your system must support DDR4 ECC Load Reduced DIMMs at 1.2V and 288-pin form factor. This memory cannot be mixed with unbuffered or ECC Registered modules and will not work in standard desktop computers.

JEDEC-compliant LRDIMM build

Each module meets JEDEC and ROHS standards with CL22 timing at 3200MHz, dropping to 2133MHz, 2400MHz, 2666MHz or 2933MHz when required. The 8Rx4 organisation and load-reduced design help maintain signal integrity on heavily populated motherboards.

Highlights

Questions about this item

Does the kit include only the two 256 GB LRDIMM modules or are any tools or cables supplied?

The kit contains two 256 GB DDR4 3200 CL22 8Rx4 288-pin 1.2 V ECC Load Reduced DIMMs; no tools or cables are included.

Should I choose this 512 GB kit or a smaller capacity for my Supermicro H12SSL-CT?

Select this 512 GB kit if the workload needs the maximum supported memory; otherwise a smaller kit saves cost while keeping the same 3200 MHz CL22 spec.

What does the 3200 MHz CL22 rating mean once the modules are installed in a server?

The modules run at 3200 MHz with CAS latency 22 and will down-clock to 2933, 2666, 2400 or 2133 MHz if the platform requires it.
