Kit composition

This OWC kit supplies 32GB of DDR4 memory in four 8GB unbuffered UDIMMs rated at 2400MHz with CL17 latency and 1.2V operation. It targets desktop PCs, workstations and compatible NAS systems that accept standard 288-pin modules.

Pre-install checks

Verify that your motherboard supports DDR4 2400MHz or the backward compatible 2133MHz speed and provides four available 288-pin slots. Confirm the board accepts non-ECC unbuffered DIMMs and that the 1.2V voltage matches the platform specification.

What the bundle changes

The four matched modules enable dual-channel operation across all populated slots, raising total capacity to 32GB without mixing densities. JEDEC and RoHS compliance means the upgrade is warranty-safe and tested to meet OEM specifications for reliable long-term use.

Questions about this item

Will this kit work in a motherboard that only supports 2133 MHz memory?

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

Does the kit require a heat spreader or active cooling for stable operation?

No, the modules have no heat spreader and operate at the standard 1.2 V, so no extra cooling is needed.

Can I mix these modules with existing ECC memory in the same system?

No, this is non-ECC memory and must not be combined with ECC modules.
