OWC 32GB DDR4 ECC RDIMM

This OWC module provides 32GB of DDR4 2400MHz PC4-19200 memory in a 288-pin ECC Registered DIMM form factor. It operates at 1.2V with CL17 latency and a 2Rx4 rank configuration. The kit is validated for specific Supermicro X11SDW motherboards including the 14CN, 14CNT, 16C and 8C series. It is designed for server and workstation environments requiring error correction.

Who this suits and who it does not

This memory suits administrators upgrading compatible Supermicro X11SDW platforms that require ECC Registered DIMMs. It supports workloads needing data integrity in server, workstation or NAS systems. It will not work in standard desktop computers that accept only unbuffered non-ECC modules. It also cannot be mixed with unbuffered memory on the same board. Buyers needing unbuffered DIMMs or higher speeds should look elsewhere.

Compatibility checks before ordering

Verify your motherboard model matches one of the listed X11SDW part numbers exactly. Confirm the system requires DDR4 2400 ECC Registered RDIMMs and supports 32GB modules per slot. Check the maximum total capacity and populated slot limits in your board manual. Ensure no unbuffered DIMMs are already installed, as mixing types is not supported.

Questions about this item

Which Supermicro motherboard models must I already own for this 32GB DDR4 2400MHz ECC RDIMM to be compatible?

This module is validated for Supermicro motherboards X11SDW-14CN-TP13F+, X11SDW-14CNT-TP13F, X11SDW-16C-TP13F, X11SDW-16C-TP13F+ and X11SDW-8C-TP13F.

Can I keep my existing unbuffered DDR4 DIMMs and add this registered 2Rx4 module alongside them?

No. The manufacturer states this ECC registered memory cannot be mixed with unbuffered memory; all installed DIMMs must be registered.

After installation, how can I verify the module is running at the rated PC4-19200 speed and CL17 latency?

Check the BIOS or UEFI memory information screen; it should report 2400 MT/s, CL17 timings and 1.2 V operation for the installed DIMM.
