OWC 8GB DDR4 2666MHz UDIMM

This OWC module is an 8GB DDR4 2666MHz CL19 unbuffered UDIMM designed for desktop PCs, workstations and NAS systems. It operates at the standard 1.2V and uses a 288-pin layout without a heat spreader or lighting. The single rank memory provides a straightforward capacity increase for everyday multitasking and larger file handling.

Check motherboard DDR4 slot and speed support

Before ordering, verify that your board accepts DDR4 UDIMMs and can run at 2666MHz, 2400MHz or 2133MHz speeds. The module is non-ECC and unbuffered, so it will not work in platforms that require registered or error-correcting memory. Confirm the system has a free 288-pin slot and that the BIOS is current enough to recognise JEDEC standard timings.

Steady operation at JEDEC voltage and timings

Under sustained load the module runs at its rated 1.2V with CL19 latency, maintaining the JEDEC specified PC4-21300 data rate without overclocking headroom. Because there is no heat spreader, airflow across the PCB helps keep temperatures stable during long sessions. The memory is tested for continuous compatibility with desktop, workstation and NAS workloads.

Questions sur cet article

Does the 8GB DDR4 2666MHz CL19 1.2V UDIMM come alone or with extra parts?

The package contains a single 8GB unbuffered 288-pin DDR4 module rated PC4-21300 CL19 at 1.2V; no heat spreader, cables or additional components are included

Should I pick the 8GB 2666MHz CL19 stick or a different capacity for my desktop?

This listing is for one 8GB module; if your board has free slots you can add more identical sticks, but no other capacities are offered under this part number

What does the 2666MHz PC4-21300 CL19 rating actually deliver in a real desktop?

The module runs at 2666MHz with CL19 latency and 1.2V; it will also operate at 2400MHz or 2133MHz if the system requires those lower speeds
