OWC 8GB DDR4 Module for Lenovo 540-15ICK

This 8GB DDR4 2666MHz CL19 UDIMM is built specifically for the Lenovo IdeaCentre Gaming 540-15ICK. It runs at 1.2V with a 288-pin unbuffered design and carries JEDEC and RoHS compliance for a warranty-safe upgrade.

1Rx8 Single-Rank Design with Backward Speed Support

The module uses a 1Rx8 organisation and operates without a heat spreader. It will also run at 2133MHz or 2400MHz if the system requires those lower speeds, simplifying installation in mixed-memory configurations.

Ideal for 540-15ICK Owners Needing

Buyers who need ECC error correction, registered modules, or capacities beyond a single 8GB stick should look elsewhere. This kit addresses only non-ECC unbuffered desktop slots in the named Lenovo model.

Questions about this item

Does this 8GB DDR4 2666MHz CL19 module require any maintenance or replacement later?

No, the non-ECC unbuffered UDIMM has no moving parts and no heat spreader, so it runs maintenance-free for its service life.

What limit appears first during sustained use on this PC4-21300 stick?

The CL19 latency at 2666MHz sets the throughput ceiling before voltage or thermal limits are reached.

How much noise, heat or power does this 1.2V 288-pin DIMM produce when running all day?

It draws 1.2V with no heat spreader, so heat output stays low and the module adds no audible noise to the system.
