OWC 128GB DDR4 ECC Registered RDIMM

This OWC module delivers 128GB of DDR4 memory at 3200MHz with CL22 latency and 1.2V operation. It uses a 288-pin registered ECC design built for server and workstation platforms. The part number is 3R2D44R4128G and it carries a 4Rx4 rank configuration.

Suited for Supermicro H12 series motherboards

This memory fits Supermicro H12DST-B, H12DSU-iN, H12SSL-C, H12SST-PS and H12SSL-i motherboards. It will not work in standard desktop computers and cannot be mixed with unbuffered modules. Builders needing non-ECC or unregistered memory should choose a different product.

128GB capacity for heavy server workloads

The single-module 128GB density provides substantial headroom for virtualisation, large databases and memory-intensive compute tasks. Systems limited to lower per-slot capacities or requiring unbuffered memory cannot use this module.

Soalan tentang produk ini

What motherboard must I already have to use this OWC 128GB DDR4 3200MHz CL22 ECC Registered RDIMM?

This module is validated for Supermicro motherboards H12DST-B, H12DSU-iN, H12SSL-C, H12SST-PS and H12SSL-i; it will not work in standard desktop boards.

Can I keep my existing unbuffered DDR4 DIMMs and add this registered ECC kit alongside them?

No, registered ECC memory cannot be mixed with unbuffered DIMMs; all slots must use registered ECC modules of matching specification.

How do I confirm the 128GB 3200MHz CL22 1.2V 4Rx4 configuration is recognised after installation?

Check the BIOS memory information or run dmidecode — it should report 128GB, DDR4 3200, CL22, 1.2V, ECC registered, 4Rx4 organisation.
