Server ECC RDIMM for NAS and Workstations

This OWC module is a 32GB DDR4 2666MHz PC4-21300 ECC Registered RDIMM built for servers, workstations and compatible NAS systems. It operates at 1.2V with CL19 latency and a 2Rx4 rank configuration on a 288-pin form factor. The memory is JEDEC and RoHS compliant and designed as a warranty-safe upgrade for supported platforms. It is validated as a replacement for Synology D4ER01-32G in the FlashStation SA6400.

Suited for registered-memory platforms.

This memory suits administrators upgrading Synology FlashStation SA6400 units or other systems that require DDR4 ECC Registered DIMMs. It will not work in standard desktop computers that accept only unbuffered non-ECC modules. It also cannot be mixed with unbuffered or load-reduced ECC memory. Buyers needing unbuffered DIMMs or consumer SODIMMs should select a different product type.

Registered ECC is the decisive compatibility factor

The single specification that decides fit is the Registered ECC DDR4 RDIMM form factor. Only systems explicitly supporting registered error-correcting DDR4 DIMMs can use this module. Verify the motherboard or NAS documentation lists DDR4 2666, 2400 or 2133 registered ECC support before purchase.

Perguntas sobre este artigo

Does this module use the 288-pin DDR4 form factor required by my Synology SA6400?

Yes, it is a 288-pin DDR4 RDIMM that matches the SA6400 slot specification.

What is the correct seating procedure for the registered ECC DIMM, and what step is often missed?

Align the notch with the key, press firmly until both side clips click, then verify the module sits flush; the missed step is skipping the clip check.

When should I plan to replace this 32 GB ECC RDIMM in a 24/7 NAS?

ECC registered modules typically run for years; replace only if memory diagnostics report correctable errors rising above threshold.
