OWC 64GB (2x32GB) DDR5 4800 CL40 ECC SODIMM laptop RAM

SKU CH-95SH-VQB7H

Dual-channel 64 GB DDR5 4800 CL40 ECC SODIMM kit with two 32 GB modules at 1.1 V for compatible laptops, all-in-ones and NAS systems

  • Capacity64GB (2 x 32GB)
  • Type262-Pin DDR5 SO-DIMM
  • CAS LatencyCL40
  • Voltage1.1V
  • ECCYes
  • Buffered/RegisteredUnbuffered

Capacity 64GB (2 x 32GB)

  • 64GB total capacity lets you run more apps simultaneously
  • DDR5 4800 speed transfers data faster than older memory
  • CL40 latency keeps response times low for smooth multitasking
  • ECC support detects and corrects errors to protect critical data
  • 1V operation reduces power draw and heat in laptops

Capacity and purpose

This kit provides 64GB of DDR5 memory in two 32GB SODIMM modules. It is built for laptops, all-in-one systems and NAS devices that support ECC unbuffered memory. The dual-channel configuration helps multitasking and large-file workflows on compatible platforms.

Sustained operation

JEDEC-standard DDR5 at 4800MHz with CL40 latency runs at a consistent 1.1V without a heat spreader. ECC error correction operates continuously to protect data integrity during long compute or storage tasks in servers and NAS units.

Deciding specification

The modules are 262-pin ECC unbuffered SODIMMs; systems that require non-ECC, registered or a different pin count cannot use this kit. Buyers must confirm their platform accepts DDR5 ECC unbuffered memory before purchase.

Questions about this item

How much heat and power does the 1.1V 4800MHz kit draw during all-day use?

The modules run at the JEDEC-standard 1.1 volts, the lowest voltage defined for DDR5, which keeps power draw and heat low enough for fanless laptops and compact NAS units. No heat spreader is fitted, so airflow from the system chassis is the only cooling required.

What must my system already provide for these 262-pin ECC SODIMMs to work?

A DDR5-compatible laptop, all-in-one or NAS with two free 262-pin SO-DIMM slots, a memory controller that supports ECC unbuffered operation, and a BIOS or firmware that enables ECC at 4800 MT/s CL40.

Will the CL40 4800MHz sticks run at full speed alongside slower DDR5 modules I might keep?

When mixed with slower DDR5, the memory controller will down-clock all modules to the lowest common speed and highest common latency; the OWC sticks will therefore run at the slower module's rate, not at their rated 4800 MT/s CL40.
