What this module is

This OWC DDR4 ECC Registered RDIMM delivers 32 GB of server-grade memory at 2133 MT/s with CL15 latency. It uses a 288-pin form factor, runs at 1.2 V and carries JEDEC and RoHS compliance for warranty-safe upgrades in compatible workstations and NAS systems.

Who it suits and who it does not

It fits administrators upgrading QNAP NAS units or other servers that require registered ECC DDR4 modules in a 2Rx4 configuration. It will not work in standard desktop PCs that accept only unbuffered non-ECC memory, and it cannot be mixed with unbuffered DIMMs in the same system.

What to verify before ordering

Confirm that your motherboard or NAS explicitly supports DDR4 2133 registered ECC RDIMMs and that the memory controller accepts 2Rx4 rank organisation. Check the maximum module capacity per slot and the total number of populated channels allowed by the platform. Ensure the system does not require a heat spreader for thermal management.

Questions sur cet article

Does my server motherboard need to support DDR4 288-pin ECC registered DIMMs for this module to work?

Yes, the module is a 288-pin DDR4 ECC registered DIMM and requires a motherboard with DDR4 RDIMM slots that accept registered memory.

Can I keep my existing unbuffered DDR4 modules and add this registered stick alongside them?

No, registered and unbuffered memory cannot be mixed; all slots must use registered ECC modules of matching type.

How can I confirm the module is running at DDR4 2133 CL15 with ECC active after installation?

Check the BIOS or UEFI memory information screen; it should show 2133 MT/s, CL15 timings and ECC enabled for the installed capacity.
