Four green circuit boards with black chips and gold contacts

OWC

OWC 1TB (4×256GB) DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Registered RDIMM Kit

SKU CH-8CDB-Y9MHK

Four 256 GB DDR4 3200 ECC registered RDIMMs add 1 TB to compatible Supermicro servers

Capacity 1TB (4 x 256GB)

  • 1TB server memory upgrade for Supermicro platforms
  • ECC registered DDR4 3200 CL22 ensures data integrity
  • Four 256GB octal-rank RDIMMs maximise capacity
  • 2V JEDEC standard voltage for efficient operation
  • Tested compatible with Samsung, Hynix and Supermicro modules

Server-grade ECC registered kit

This OWC kit supplies 1 TB of DDR4 ECC registered memory across four 256 GB modules. It is built for Supermicro workstation and server boards including H12SSW-iN, X12DPG-OA, H11DSi, H11SSL-NC and H12SSW-NT. The modules run at 3200 MT/s with CL22 latency at 1.2 V.

Replaces unbuffered or mixed-rank DIMMs

The upgrade replaces unbuffered or load-reduced DIMMs that cannot operate alongside registered memory. The jump is worth it when the platform requires registered ECC and the workload demands the full 1 TB capacity across all populated slots.

Limited to registered-ECC platforms

The DDR4 registered interface only functions in motherboards that support 8Rx4 registered ECC DIMMs. Standard desktop boards and any system lacking registered-ECC support will not recognise these modules.

Questions about this item

Does this 288-pin RDIMM kit fit the Supermicro H12SSW-iN motherboard?

Yes, the kit is listed as compatible with the H12SSW-iN, X12DPG-OA, H11DSi, H11SSL-NC and H12SSW-NT motherboards.

What is the correct way to populate all four slots on a compatible Supermicro board?

Install the four 256GB modules in the four slots designated for the same memory channel configuration per the motherboard manual; the common error is mixing these ECC Registered RDIMMs with unbuffered or load-reduced memory.

When should one of the 256GB modules be replaced?

Replace a module if the system logs report uncorrectable ECC errors on that specific DIMM or if memory diagnostics consistently fail on the same stick.
