OWC DDR4 2666 SODIMM Kit
This kit provides 16 GB of DDR4 laptop memory across two 8 GB modules. It runs at 2666 MHz with CL19 timing and a standard 1.2 V operating voltage. The 260-pin SODIMM form factor fits laptops, all-in-one PCs and compatible NAS units. The modules are unbuffered and non-ECC, matching JEDEC specifications.
Suits owners of DDR4 systems needing 16 GB
The dual-channel kit upgrades compatible laptops, mini desktops, micro servers and POS hardware that accept 260-pin SODIMMs. It is backward compatible with 2400 MHz and 2133 MHz slots. Buyers whose platforms require ECC or registered memory should look elsewhere, as will anyone needing a single module or a capacity beyond 16 GB.
16 GB handles everyday multitasking and larger files
Two 8 GB sticks give comfortable headroom for web browsing, office suites and light creative work. The kit runs out when workloads demand more than 16 GB total or when the host system caps memory at a lower limit. Speed drops to 2400 MHz or 2133 MHz on older controllers, reducing peak bandwidth accordingly.

Questions about this item
What type of memory slots does my laptop need to accept this 260-pin DDR4 SO-DIMM kit?
Your laptop must provide DDR4 SO-DIMM slots that accept 260-pin modules operating at 1.2V.
Will these 2666MHz modules downclock if I keep my existing 2400MHz or 2133MHz memory installed?
Yes, the kit is backwards compatible and will run at 2400MHz or 2133MHz to match the slower modules.
How can I confirm the dual-channel kit is running at the correct 2666MHz speed and CL19 timings after installation?
Check the memory speed and CAS latency in your system BIOS or a tool like CPU-Z; they should show 2666MHz and CL19.
