32GB DDR4 ECC Registered RDIMM
This OWC module delivers 32GB of DDR4 2933MHz memory with CL21 latency and 1.2V operation. It uses a 2Rx4 registered design with ECC for error correction in server and workstation environments. The 288-pin RDIMM form factor fits compatible enterprise platforms.
Upgrade path and backward compatibility
The module replaces slower DDR4 DIMMs and runs at 2133MHz, 2400MHz or 2666MHz when the platform requires it. The jump is worth it when your workload needs the full 2933MHz bandwidth and the motherboard supports registered ECC memory. It will not work in standard desktop boards that accept only unbuffered DIMMs.
Platform verification before ordering
Confirm that your server, workstation or NAS system requires 288-pin DDR4 registered ECC RDIMMs and supports the PC4-23400 speed grade. Check the system manual for maximum capacity per slot and whether 2Rx4 modules are qualified. Do not mix this registered module with unbuffered memory in the same system.

Questions about this item
Will this 288-pin DDR4 RDIMM fit in my server's memory slots?
The module uses the standard 288-pin DDR4 RDIMM form factor. It requires a server or workstation motherboard with registered DIMM slots; it will not fit standard desktop boards.
What is the correct way to install this ECC registered module, and what mistake should I avoid?
Power down the system, align the notch with the slot key, and press firmly until the retention clips click. The common error is mixing this registered memory with unbuffered modules, which the manufacturer warns against.
Does this 32GB module need any firmware updates or periodic replacement?
No firmware updates are required for the memory itself. It is a solid-state component with no moving parts, so it does not have a scheduled replacement interval under normal server operating conditions.
