32GB DDR4 kit for desktop upgrades

This OWC kit delivers 32GB of DDR4 memory across eight 4GB unbuffered UDIMMs. It is built for desktop PCs, workstations and NAS systems that accept 288-pin modules. The dual-channel configuration helps multitasking and larger-file workflows without requiring ECC support.

JEDEC-compliant 1.2V modules with no heat spreader

Each stick runs at the standard 1.2 volts and meets JEDEC PC4-19200 specifications, so it drops into compatible boards without voltage tweaks. The black PCBs have no heat spreader, keeping the profile low for tight DIMM spacing or compact chassis. Backward compatibility with 2133MHz systems is also specified.

Lifetime warranty and free tech support included

OWC backs the kit with a limited lifetime warranty and an advanced replacement programme plus free technical support. The package contains only the eight memory modules; no additional cables, software licences or installation tools are bundled.

Questions about this item

Will these modules work in a motherboard that only supports DDR4 2133?

Yes, the kit is backward compatible with 2133MHz systems and will run at the lower speed automatically.

How many DIMM slots do I need free to install the full 32GB kit?

You need eight free 288-pin slots because the kit contains eight individual 4GB modules.

Can I add this kit alongside existing DDR4 memory that runs at a different speed?

The system will run all modules at the speed of the slowest installed kit, so mixing speeds is possible but reduces overall performance.
