OWC 32GB DDR5 4800 UDIMM

This OWC memory module provides 32GB of DDR5 capacity for desktop, workstation, NAS and all-in-one systems. It operates at 4800MHz with a CAS latency of CL40 and a standard voltage of 1.1V. The unbuffered 288-pin design follows JEDEC specifications for broad compatibility.

Non-ECC upgrade for mainstream builds

The module suits users expanding a non-ECC desktop platform that accepts DDR5 UDIMMs. Systems requiring registered or ECC memory cannot use this part. Buyers needing heat spreaders or RGB lighting should select a different product.

Single 32GB density per slot

Each stick delivers the full 32GB in one rank configuration, letting you reach higher total capacities with fewer occupied slots. Verify your motherboard supports 32GB single-module density before purchase.

Questions about this item

What motherboard slot and DDR generation are required for this 288-pin DDR5 4800 UDIMM?

A desktop motherboard with a DDR5 288-pin UDIMM slot is required; the module runs at 4800 MT/s and 1.1 V.

How will this CL40 DDR5 4800 module behave if installed alongside slower DDR5 DIMMs I keep?

The system will run all DIMMs at the speed and timings of the slowest module, so this CL40 4800 stick will down-clock to match.

How can I confirm the OWC 32 GB module is running at its rated 4800 MT/s CL40 after installation?

Check the memory tab in CPU-Z or your BIOS/UEFI and verify the DRAM frequency reads 4800 MT/s with CAS latency 40.
