DDR3 1066 desktop kit

This OWC kit supplies 4GB of DDR3 memory as two 2GB unbuffered UDIMMs rated at 1066MHz with CL7 latency and 1.5V operation. The modules follow JEDEC PC3-8500 specifications and use standard 240-pin connectors for desktop platforms.

Fits older DDR3 systems

The kit suits desktops and workstations that accept DDR3 1066 unbuffered non-ECC DIMMs and have two available slots for dual-channel population. Systems requiring ECC, registered modules, higher speeds or different voltages should use other memory.

Steady throughput at rated speed

Under sustained load the modules maintain their 1066MHz data rate and CL7 timing at 1.5V without a heat spreader. The JEDEC-compliant design keeps performance consistent during extended multitasking or large-file workloads.

Perguntas sobre este artigo

What motherboard slot does this 240-pin DDR3 kit require?

The modules fit a standard DDR3 240-pin UDIMM slot running at 1.5V.

Can I mix these CL7 1066MHz sticks with slower DDR3 already in my PC?

Yes, the system will run all modules at the speed of the slowest installed kit.

How do I confirm the dual-channel kit is active after install?

Check the BIOS or OS memory report; it should show 4GB total at 1066MHz in dual-channel mode.
