8 GB DDR3 ECC UDIMM for workstations

This module adds 8 GB of DDR3 memory rated at 1066 MHz with CL7 latency. It is an unbuffered ECC DIMM designed for select desktops, workstations and NAS systems that require error-correcting code memory. The single 240-pin stick runs at the standard 1.5 V JEDEC voltage.

Check motherboard DDR3 ECC support

Verify that your board accepts DDR3 unbuffered ECC UDIMMs and has a free 240-pin slot. The system must be able to run memory at 1.5 V and support the PC3-8500 speed grade. Confirm the maximum capacity per slot and total system limit in the manual before ordering.

Thermals noise and power draw

The module has no heat spreader and relies on case airflow for cooling. At 1.5 V and 1066 MHz it draws modest power and produces no audible noise because there are no moving parts. Typical operating temperatures stay within JEDEC limits when chassis ventilation is adequate.

Questions about this item

Does the OWC 8GB DDR3 1066 module arrive as a single stick or a kit, and is anything else required for installation?

The package contains one 8GB DDR3 1066 PC3-8500 CL7 240-pin 1.5V ECC unbuffered UDIMM. No extra components are needed; the module installs directly into a compatible DDR3 slot.

When should I pick this 8GB DDR3 1066 CL7 ECC unbuffered UDIMM instead of a non-ECC or registered alternative?

Choose this module when your workstation, server or NAS requires ECC error correction and an unbuffered 240-pin DDR3 DIMM running at 1066 MHz with CL7 latency at 1.5 V.

What does the PC3-8500 1066 MHz CL7 rating actually deliver once the DIMM is seated in a desktop or server?

The module operates at 1066 MHz with a CAS latency of 7 cycles at 1.5 V, providing JEDEC-standard DDR3 bandwidth and ECC data integrity for compatible desktop, workstation or server platforms.
