64GB DDR5 5600 dual-channel kit

This OWC kit provides 64GB of DDR5 memory across two 32GB modules running at 5600MT/s with CL46 latency. It is an unbuffered, non-ECC UDIMM designed for desktop, workstation, NAS and all-in-one systems. The 1.1V JEDEC-standard voltage ensures broad platform compatibility for users seeking a straightforward capacity upgrade.

Check motherboard DDR5 support and slot count

Verify that your board accepts DDR5 UDIMMs and has at least two free 288-pin slots for dual-channel operation. Confirm the maximum supported speed and total capacity per slot in your system documentation before ordering. The modules operate at the standard 1.1V JEDEC voltage with no XMP or EXPO profiles required.

Standard voltage keeps thermals and power low

At the JEDEC 1.1V baseline the kit draws minimal power and generates little heat during typical workloads. With no heat spreader or RGB lighting there are no active cooling components to add noise. The low-voltage design helps maintain stable temperatures inside compact desktop and all-in-one chassis.

Questions about this item

What comes in the 64GB kit and is anything else needed to install it?

The kit contains two 32GB DDR5 5600 CL46 UDIMM modules; no extra parts are required for a standard desktop DIMM slot.

Why choose this 64GB dual-channel kit over a single 64GB stick?

Two 32GB sticks run in dual-channel mode, doubling memory bandwidth compared with a single 64GB module at the same 5600 MT/s speed.

What does the 5600 CL46 rating deliver in a real desktop?

It provides JEDEC-standard 5600 MT/s transfer rate with 46-cycle latency at 1.1V, giving stable plug-and-play performance without manual tuning.
