Server-grade DDR4 ECC RDIMM

This 32 GB DDR4 2400 module delivers error-correcting registered memory for servers, workstations and NAS systems. It runs at 1.2 V with CL17 latency and a 2Rx4 organisation across 288 pins. The design targets administrators who need reliable capacity expansion without changing platform voltage.

Replaces Kingston KVR24R17D4/32 and KVR24R17D4/32MA

The OWC part matches the exact JEDEC PC4-19200 specification of those Kingston modules, so it slots into the same qualified memory lists. The jump is worth it when you need to populate empty DIMM slots or swap out smaller registered DIMMs to reach higher total capacity in validated configurations.

Verify registered ECC support before ordering

Your motherboard and CPU must explicitly support DDR4 registered ECC RDIMMs; standard desktop boards will not accept them. Registered modules cannot be mixed with unbuffered memory in the same system. Confirm the platform’s qualified-vendor list includes 2Rx4 2400 MHz parts and that enough 288-pin slots remain free.

Questions about this item

Does the 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin registered DIMM matches the standard DDR4 RDIMM slot used in servers, workstations and NAS systems.

What is the correct way to seat the 288-pin module so the register engages?

Align the notch with the slot key, press straight down until both retention clips click, ensuring the register makes full contact.

When should the 32GB ECC registered module be replaced?

Replace it if memory diagnostics report uncorrectable ECC errors or the system logs repeated corrected errors over time.
