OWC 32 GB DDR5 4800 ECC UDIMM

This 32 GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1 V operation. It is an unbuffered ECC UDIMM built to JEDEC standards for data-integrity workloads. The 288-pin form factor fits desktop, workstation, NAS and all-in-one platforms. OWC validates every unit for warranty-safe upgrades.

Suited for ECC workstations and NAS not gaming rigs

Systems that require error-correcting memory for file servers, ZFS pools or virtualization hosts will benefit from this module. Consumer desktops without ECC support in the CPU or chipset cannot use the error-correction function. Builders needing registered DIMMs or non-ECC speeds should select a different part.

Deciding spec is 32 GB ECC unbuffered at 4800

The single figure that determines fit is the 32 GB ECC unbuffered density at 4800 MT/s. If the platform accepts only non-ECC or registered memory this module will not post. Confirm the motherboard QVL lists 2Rx8 unbuffered ECC UDIMMs before purchase.

Questions about this item

Does this module fit a standard 288-pin DDR5 UDIMM slot on a desktop motherboard?

Yes, it uses the 288-pin DDR5 UDIMM form factor that matches standard desktop slots.

Will the ECC function work on a consumer desktop board?

ECC operates only when the CPU and motherboard both support ECC UDIMMs; otherwise the module runs as non-ECC memory.

Is any voltage adjustment needed in the BIOS?

The module runs at the JEDEC-standard 1.1 V, so no manual voltage change is required.
