32GB DDR4 ECC UDIMM kit

This OWC kit provides 32GB of DDR4 ECC unbuffered memory across two 16GB modules. It runs at 2933MHz with a CL21 latency and operates at 1.2V. The 288-pin UDIMMs are designed for desktop workstations, servers and NAS systems that require error-correcting code memory.

Suited for ECC-capable platforms only

The modules are built for systems that support ECC unbuffered DDR4 UDIMMs, such as compatible workstations, servers and NAS units. They will not function correctly in standard consumer desktops or laptops that lack ECC support in the CPU and chipset. Buyers without ECC-capable hardware should choose non-ECC memory instead.

ECC unbuffered UDIMM requirement

The single specification that decides fitment is whether the target system accepts DDR4 ECC unbuffered UDIMMs at 288 pins. If the motherboard and processor do not explicitly support ECC unbuffered memory, these modules will not work. Verify the platform documentation for ECC UDIMM compatibility before purchasing.

Perguntas sobre este artigo

What motherboard slot does this 288-pin DDR4 UDIMM require?

It fits a standard DDR4 288-pin DIMM slot on a desktop, workstation, server or NAS motherboard that supports unbuffered ECC memory at 1.2V.

Will the 2933MHz CL21 modules run with my existing 2400MHz DDR4 sticks?

Yes, the kit is backward compatible with 2133MHz, 2400MHz and 2666MHz DDR4; the system will operate all modules at the lowest common speed.

How can I confirm the ECC function is active after installing the 2x16GB kit?

Enter the BIOS or UEFI and verify that ECC is shown as enabled, or run a memory diagnostic that reports ECC correction events for the 32GB capacity.
