64 GB Dual-Channel DDR5 Kit

This OWC kit provides 64 GB of DDR5 memory in two 32 GB unbuffered UDIMMs. It runs at 4800 MT/s with a CAS latency of 40 and operates at the standard 1.1 V. The modules are non-ECC and carry no heat spreaders. They are built for desktop, workstation, NAS and all-in-one systems that accept 288-pin DDR5 DIMMs.

Suited For Standard DDR5 Platforms

The kit suits users who need a JEDEC-compliant 64 GB upgrade for a desktop, workstation or NAS that supports DDR5 4800. Builders who require ECC error correction, registered modules, lower latency timings, RGB lighting or integrated heat spreaders should look at other products. The 1.1 V voltage matches the baseline DDR5 specification.

DDR5 4800 CL40 1.1 V Specification

The decisive specification is the DDR5 4800 speed rating combined with CL40 latency at 1.1 V. This JEDEC-standard profile determines whether the memory will train correctly on a given motherboard without manual tuning. If the platform only qualifies faster or lower-latency modules, this kit may not be the right choice.

Questions about this item

Will this kit work in a motherboard that only supports DDR5 4800?

Yes, the modules run at DDR5 4800 (PC5-38400) with CL40 timing and 1.1 V, matching that specification exactly.

Is the memory compatible with a NAS or all-in-one desktop that uses 288-pin UDIMM slots?

The kit uses standard 288-pin unbuffered non-ECC DDR5 DIMMs, which fit desktops, workstations, NAS systems and all-in-one PCs with DDR5 slots.

What do I need to add to run this kit in dual-channel mode?

The package already contains two matched 32 GB modules, so installing both in the correct motherboard slots enables dual-channel operation automatically.
