Laptop DDR4 SODIMM kit
This OWC kit provides 8 GB of DDR4 memory in two 4 GB modules. It targets laptops, all-in-one PCs and NAS units that accept 260-pin SODIMMs. The dual-channel layout lets the memory controller interleave data across both sticks. Buyers needing a single larger module or ECC support should look elsewhere.
260-pin dual-channel fit
Each module uses the standard 260-pin SODIMM form factor and runs at 1.2 V without buffering or ECC. The pair installs into adjacent slots to enable dual-channel operation on compatible platforms. Systems with only one SODIMM slot cannot use both modules at once. No heat spreader is fitted, so clearance inside thin chassis is not affected.
2666 MHz CL19 headroom
Rated at DDR4 2666 with CAS latency 19, the kit also runs at 2400 MHz and 2133 MHz when the platform requires lower speeds. The 8 GB total capacity suits everyday multitasking and typical office workloads. Users editing large media files or running virtual machines will exhaust this capacity quickly.

Questions about this item
Will the CL19 latency limit throughput during sustained workloads?
CL19 is the JEDEC-standard timing for DDR4 2666 modules and does not create an artificial bottleneck under continuous use.
How much heat or power do these modules draw when running all day?
Each stick operates at 1.2 V with no heat spreader, matching the low-power DDR4 SODIMM profile for laptops and NAS units.
What must my system already have for this dual-channel kit to function?
A laptop, mini desktop or NAS with two free 260-pin DDR4 slots that support 2666, 2400 or 2133 MHz operation.
