32GB dual-channel DDR5 kit

This OWC kit provides 32GB of desktop memory as two 16GB unbuffered UDIMMs. The modules run at DDR5 5200 (PC5-41600) with CL42 latency at the standard 1.1V JEDEC voltage. They are non-ECC, 288-pin DIMMs without heat spreaders or LEDs, built for straightforward installation in compatible desktop platforms.

Suited for standard desktop upgrades

The kit fits desktops, workstations, NAS units and all-in-one systems that accept non-ECC DDR5 UDIMMs at JEDEC speeds. It will not work in systems that require registered or ECC modules, nor in platforms limited to earlier DDR generations. Builders needing lower latency, higher frequencies, RGB lighting or integrated heat spreaders should consider other kits.

DDR5 5200 CL42 at 1.1V JEDEC

The decisive specification is the JEDEC-standard DDR5 5200 speed with CL42 timings at 1.1V. If your motherboard and CPU support this exact speed and voltage without overclocking, the kit will operate at its rated performance. If the platform only supports slower DDR5 speeds or requires different timings, the modules will downclock or may not be compatible.

Questions about this item

Will the 288-pin DDR5 UDIMMs fit my desktop's standard DIMM slots?

Yes, each 16 GB module uses the 288-pin unbuffered DDR5 form factor that matches ordinary desktop DIMM sockets.

Is there a specific slot order or BIOS step required when installing the two sticks?

Install one stick in each primary channel slot — usually the second and fourth slots from the CPU — then enable XMP or the 5200 MT/s profile in BIOS so the kit runs at its rated CL42 speed.

How long are the modules covered if one fails down the road?

OWC provides a limited lifetime warranty with an advanced replacement program, so a defective stick can be swapped without waiting for a return to be processed.
