Kit contents and purpose

This OWC kit provides 8 GB of DDR3 desktop memory arranged as a matched dual-channel pair of two 4 GB UDIMMs. It is built for DDR3 platforms that accept 240-pin unbuffered non-ECC modules running at 1.5 V.

Who this suits and who should look elsewhere

The kit fits desktop and workstation boards with DDR3 slots that support PC3-12800 CL11 timing. Systems requiring ECC, registered DIMMs, a different voltage, or a newer DDR generation cannot use these modules.

Deciding specification

The modules operate at DDR3 1600 with a CAS latency of 11 at 1.5 V, so the board must support that exact speed, timing and voltage combination for the kit to run as specified.

Questions about this item

Will this 1.5V kit run with my existing DDR3 modules?

Both kits must operate at the same 1.5V voltage and share the same DDR3 1600 speed for stable dual-channel operation; mixing different speeds or voltages can cause instability.

How can I confirm the 1600 CL11 kit is running correctly after install?

Enter the system BIOS or use a tool like CPU-Z to verify the memory reports DDR3 1600 (PC3-12800) at CL11 timings and 1.5V with both 4GB modules detected in dual-channel mode.

What comes in the box and what must I source separately?

The box contains two 4GB 240-pin UDIMM modules; no heat spreaders, cables, or tools are included, and no extra components are required for installation in a compatible desktop.
