ECC Unbuffered UDIMM for Workstations

This OWC module delivers 8GB of DDR4 memory rated at 3200MHz with a CL22 latency. It operates at the standard 1.2V and uses a 288-pin unbuffered design with on-die error correction. The single-rank 1Rx8 layout suits workstations, servers and NAS units that require data integrity without registered signalling.

JEDEC Compliant and Backward Compatible

The stick meets full JEDEC specifications and is ROHS compliant, ensuring a warranty-safe upgrade for OEM systems. It will automatically down-clock to 2133MHz, 2400MHz, 2666MHz or 2933MHz when paired with slower memory controllers, so it integrates into existing DDR4 platforms without configuration changes.

Low-Profile Black PCB for Dense Builds

A bare black circuit board without a heat spreader keeps the module height minimal, helping it fit in crowded DIMM arrays or compact 1U chassis. The 288-pin gold-edge connector provides reliable seating in standard desktop UDIMM slots, and the unbuffered topology means no extra register delay for typical workstation and server boards.

Questions about this item

Will this module work in a motherboard that only supports non-ECC memory?

No, this is an ECC module and requires a motherboard and CPU that support ECC functionality.

Does the 3200 MHz rating mean it will not run in a system rated for 2666 MHz?

It is backward compatible with 2133 MHz, 2400 MHz, 2666 MHz and 2933 MHz systems and will run at the highest speed the platform allows.

Is a heat spreader included, and do I need one for a workstation build?

The module has no heat spreader; it runs at the standard 1.2 V and is designed for standard airflow in workstations, servers and NAS enclosures.
