OWC 32GB DDR5 4800 CL40 2Rx8 262-pin 1.1V Non-ECC SODIMM laptop RAM

SKU CH-82H1-Q4YHQ

A 32 GB DDR5 SODIMM running at 4800 MHz with CL40 latency and 1.1 V operation for laptops and all-in-one systems

  • Total capacity32 GB
  • CAS latencyCL40
  • Rated voltage1.1 V
  • Buffer typeUnbuffered
  • Recommended forLaptops, All-in-One Systems, and NAS Systems
  • Product type262-Pin DDR5 SO-DIMM

Capacity 32GB

  • Boosts system responsiveness with 4800MHz DDR5 speed
  • 32GB single module expands multitasking headroom
  • Low 1.1V operation reduces power draw
  • JEDEC-standard CL40 timing ensures broad compatibility
  • 262-pin SODIMM fits laptops, all-in-ones and NAS

Single-module upgrade

This OWC module adds 32GB of DDR5 memory to a compatible laptop, all-in-one or NAS system. It uses the 262-pin SO-DIMM form factor and runs at the JEDEC-standard 4800 MT/s with CL40 latency. The 1.1V operating voltage matches the DDR5 baseline specification.

Builders with one free slot

Systems that accept a single 32GB DDR5 SO-DIMM will gain the full capacity increase from this module. Machines that require ECC, registered DIMMs, or a different pin count cannot use this part. Buyers needing more than 32GB in a single slot should look at higher-density modules.

32GB density in one SO-DIMM

The 2Rx8 organisation delivers the full 32GB capacity within a single 262-pin module. This density decides whether the upgrade fits the platform's maximum per-slot limit.

Questions about this item

Will the 262-pin DDR5 SODIMM fit my laptop's memory slot?

This module uses the standard 262-pin DDR5 SO-DIMM form factor. It fits laptops and all-in-one systems that have a DDR5 SO-DIMM slot. Check your device manual to confirm it supports DDR5 memory.

What is the correct way to seat the 262-pin module so it locks in place?

Align the notch on the module with the key in the slot, insert at a slight angle, then press down firmly until the side clips click. The step often missed is pressing evenly on both ends until both clips engage fully.

Does the 32GB CL40 1.1V module need any firmware updates or cooling pads over time?

No firmware updates are required for the memory itself. The module runs at 1.1V without a heat spreader, so ensure your laptop's internal airflow remains clear; no extra cooling pads are needed.
