Single-module capacity and ECC

This module delivers 32GB of DDR4 memory in a single unbuffered UDIMM. It is built for desktop PCs, workstations, servers and NAS systems that require error-correcting code protection. The 288-pin form factor fits standard DDR4 slots on compatible platforms.

DDR4 2933 speed and backward steps

The module runs at 2933MHz with a CL21 latency at 1.2V. It is also compatible with systems limited to 2133MHz, 2400MHz or 2666MHz speeds. JEDEC compliance ensures the DIMM will operate at the highest speed the platform and memory controller allow.

32GB headroom for heavy workloads

A single 32GB stick provides substantial capacity for virtual machines, large datasets and multi-application workflows. Workstations and servers can populate multiple slots to reach higher totals, while NAS units benefit from the ECC integrity during sustained file operations.

Questions about this item

Will this 32GB module fit my desktop motherboard?

It uses the standard 288-pin UDIMM form factor for DDR4 desktop boards. Your motherboard must support DDR4, unbuffered ECC memory and a 32GB single-module capacity. Check the manual or vendor memory QVL for confirmed compatibility.

Can I use this ECC stick in a system that does not support ECC?

The module is ECC unbuffered. If your platform does not support ECC it will typically ignore the extra parity bits and run as non-ECC, but some consumer chipsets disable the slot entirely. Verify your motherboard or CPU documentation before buying.

My board only lists 2666MHz memory — will this 2933MHz module still work?

Yes. The specification states backward compatibility with 2133MHz, 2400MHz and 2666MHz speeds. The module will automatically down-clock to the highest speed your platform supports while keeping CL21 timings at 1.2V.
