32GB DDR3 ECC Kit for Workstations

This kit provides 32GB of DDR3 memory arranged as eight 4GB modules. It is built for desktops, workstations and servers that require ECC unbuffered DIMMs. The modules run at 1066MHz with a CL7 latency and operate at 1.5V. JEDEC compliance ensures broad compatibility with supported platforms.

Thermals and Power in Daily Use

The modules have no heat spreaders and rely on standard case airflow for cooling. At 1.5V they draw modest power consistent with DDR3 1066 operation. ECC circuitry adds a small overhead but does not change the thermal profile in normal workloads. Fan noise will depend on the chassis rather than the memory itself.

What the Bundle and Software Deliver

The package contains eight matched 240-pin UDIMMs packaged as a dual-channel kit. No additional software, LEDs or accessories are included. OWC validates every module in-house and backs the kit with a limited lifetime warranty and an advanced replacement program. Free technical support is available for installation questions.

Questions about this item

Will this 32 GB kit work in a standard desktop motherboard?

The modules are 240-pin DDR3 UDIMMs rated at 1.5 V, so they fit any desktop board that accepts unbuffered ECC DDR3 at 1066 MHz.

Do I need to populate all eight slots to use the kit?

The kit contains eight matched 4 GB modules; you can install fewer, but the full 32 GB capacity requires all eight slots.

Is the memory registered or unbuffered?

These are unbuffered ECC DIMMs, not registered, making them compatible with workstation and server boards that support unbuffered ECC.
