Legion T530/T730 8GB DDR4-2666 UDIMM

This OWC 8GB DDR4 2666MHz CL19 1.2V 288-pin UDIMM is built for Lenovo Legion T530-28APR, T530-28ICB and T730-28ICO desktops. It meets JEDEC specifications and runs at the native speed these systems expect.

Owners of the listed Legion models adding capacity

Builders working on other motherboards should look at something else because this module is validated only for the three Legion model numbers above. Systems that require ECC or registered memory cannot use this non-ECC unbuffered stick.

2666MHz CL19 JEDEC speed rating

The module operates at DDR4-2666 with CL19 latency at 1.2V and is backward compatible with 2133MHz and 2400MHz bus speeds. This single speed grade determines whether the memory matches the platform's supported frequency.

Questions about this item

Will this 2666MHz DDR4 module run reliably alongside my existing 2400MHz sticks in the Legion T530?

Yes, the module is backward compatible with 2133MHz and 2400MHz speeds, so it will downclock to match your current memory and operate at the lower frequency.

How can I confirm the 8GB stick is detected at the correct 2666MHz CL19 timings after installation?

Open Task Manager or BIOS and verify the memory shows 8GB capacity, 2666MHz speed and CL19 latency; the module follows JEDEC standards so it should configure automatically.

Does the 288-pin UDIMM come with a heat spreader or any extra accessories in the box?

The module has no heat spreader and ships as a single 8GB DDR4 UDIMM; no additional cables, tools or brackets are included.
