Single-module 32GB capacity

This OWC module provides 32GB of DDR4 memory in one 288-pin UDIMM. It runs at 2666MHz with CL19 latency and 1.2V operation. The unbuffered non-ECC design targets standard desktop PCs, workstations and NAS systems.

JEDEC and ROHS compliance

The module meets JEDEC standard specifications and is ROHS compliant, making it a warranty-safe upgrade for OEM systems. No additional software or accessories are bundled; the benefit comes from the validated component itself.

DDR4 2666MHz interface limits

The DDR4 interface operates at 2666MHz (PC4-21300) and is backward compatible with 2133MHz and 2400MHz bus speeds. Maximum throughput and latency are bounded by the DDR4 standard and the CL19 timing of this module.

Questions about this item

Will this single 32 GB module work in a desktop that currently runs 2133 MHz or 2400 MHz memory?

Yes, the module is backward compatible with 2133 MHz and 2400 MHz systems and will run at the highest speed the platform supports.

Does the 288-pin UDIMM fit a standard consumer desktop motherboard slot?

The 288-pin unbuffered DIMM matches the standard DDR4 desktop slot used on most consumer and workstation boards.

Is any BIOS change or voltage adjustment needed for the 1.2 V specification?

The module operates at the standard DDR4 1.2 V, so no manual voltage setting is required on compatible platforms.
