OWC 32GB DDR5 ECC SODIMM

This OWC module delivers 32GB of DDR5 memory at 4800 MT/s with CL40 latency and ECC error correction. It uses the 262-pin SO-DIMM form factor and operates at the standard 1.1V voltage. The unbuffered design targets laptops, all-in-one PCs and NAS units that support DDR5 ECC memory.

Suits ECC-capable mobile workstations

Systems that require error-correcting code for data integrity will benefit from this module. Builders whose platforms only accept non-ECC or registered DIMMs cannot use this part. Buyers needing higher capacity per slot or lower latency timings should look at alternative configurations.

32GB single-module capacity for demanding workloads

The 32GB density handles large datasets, virtual machines and multi-application workflows comfortably. Workloads that exceed 32GB of physical memory will require additional slots or higher-density modules. The JEDEC-standard 4800 MT/s speed provides baseline DDR5 bandwidth for supported platforms.

Questions about this item

My laptop requires a 262-pin DDR5 SO-DIMM running at 1.1 V — does this module match that requirement?

Yes, this is a 262-pin DDR5 SO-DIMM rated at 1.1 V, PC5-38400 4800 CL40, designed for laptops, all-in-ones and NAS systems.

I plan to keep my existing DDR5 4800 CL40 ECC SODIMM and add this 32 GB stick — will they run together at the rated speed?

Both sticks share the same DDR5 4800 CL40 1.1 V ECC unbuffered specification, so the memory controller should operate them in dual-channel at the rated 4800 MT/s.

After installing the module, how can I confirm it is running as ECC unbuffered DDR5 4800 CL40 at 1.1 V?

In the BIOS or UEFI memory information screen, verify the reported speed shows 4800 MT/s, CAS latency 40, voltage 1.1 V and ECC status enabled.
