16 GB DDR3 kit for desktop upgrades

This OWC kit provides 16 GB of DDR3 memory in a matched set of four 4 GB modules. It is intended for desktop and workstation systems that use 240-pin unbuffered DIMMs. The kit targets users who need a straightforward capacity increase for everyday multitasking.

1600 MHz CL11 capacity and headroom

Running at 1600 MHz with CL11 latency and 1.5 V, the modules deliver standard DDR3 throughput for office applications, web browsing and light creative work. The 16 GB total gives comfortable headroom for multiple browser tabs and background services, while memory-intensive tasks such as large video projects or virtual machines will exhaust the available space.

JEDEC compliance and lifetime support

The modules are built to JEDEC and RoHS standards, ensuring a warranty-safe upgrade that meets OEM specifications. OWC includes a limited lifetime warranty with free technical support and an advanced replacement programme. No heat spreaders or lighting are fitted, keeping the profile low for tight motherboard layouts.

Questions about this item

Will this kit work in a motherboard that only accepts DDR3 1.5 V DIMMs?

Yes, the modules run at 1.5 V and are standard DDR3 1600 CL11 UDIMMs, matching that requirement exactly.

My board has four slots and supports dual-channel; how should I populate them?

Install all four 4 GB sticks to fill the board and run in dual-channel mode for 16 GB total.

Are these modules compatible with a workstation that specifies PC3-12800 non-ECC memory?

The kit is rated PC3-12800, non-ECC, unbuffered, and JEDEC compliant, so it meets that specification.
