OWC 32GB DDR5 4800 CL40 288-pin 1.1V Non-ECC UDIMM desktop RAM

What this 32 GB DDR5 module does

This 32 GB DDR5 4800 CL40 UDIMM adds capacity to desktops, workstations, NAS units and all-in-one PCs. It runs at 1.1 V and follows JEDEC PC5-38400 timing, so the system configures it automatically without manual tuning.

Installing the 288-pin DIMM

Align the notch on the 288-pin edge connector with the slot key, press down until the retention clips click, and the motherboard will train at 4800 MT/s. The most common issue is mixing this CL40 stick with faster or slower modules, which can force the whole kit to run at the lowest common speed or prevent boot.

Suits mainstream DDR5 upgrades

The module suits owners of DDR5 platforms that officially support 4800 MT/s CL40 and need a single 32 GB rank for multitasking or larger datasets. Builds requiring ECC, registered buffering, lower latency bins, or speeds above 4800 MT/s should choose a different part.
