OWC 128GB DDR4 SO-DIMM kit

This kit supplies 128GB of DDR4 laptop memory across eight 16GB modules. It runs at 2666MHz with CL19 latency and 1.2V operation. The 260-pin SO-DIMM form factor fits compatible notebooks, all-in-one PCs and NAS units. Non-ECC unbuffered design suits consumer and light commercial workloads.

Ideal for high-capacity laptop and NAS upgrades

Content creators and power users who need the maximum supported memory in an eight-slot system will benefit. Builders with only two or four slots cannot use the full kit. Systems requiring ECC or registered modules should look elsewhere. The dual-channel kit labelling applies to paired operation, not to the eight-module count.

Verify slot count and DDR4 support before ordering

Confirm the target device accepts eight 260-pin SO-DIMMs and runs DDR4 at 2666MHz, 2400MHz or 2133MHz. Check the manufacturer’s qualified-vendor list for 16GB 2Rx8 density support. Ensure the BIOS can address the full 128GB capacity. No heat spreaders are included, so verify chassis airflow.

商品問答

Does my laptop need eight 260-pin DDR4 SO-DIMM slots to use all 128 GB from this kit?

Yes, the kit contains eight 16 GB modules, so the system must provide eight DDR4 SO-DIMM sockets to install the full capacity.

Will these 2666 MHz CL19 modules run reliably if my notebook only supports 2400 MHz or 2133 MHz memory?

The modules are backward compatible with 2400 MHz and 2133 MHz speeds, so they will operate at the lower frequency your platform requires.

How can I verify the kit is running at 2666 MHz with CL19 timings after installation?

Check the memory speed and CAS latency reported in your BIOS or a system-information tool such as CPU-Z; they should show 2666 MHz and CL19 when the system is configured for the rated profile.
