System-Specific DDR4 Upgrade for Lenovo IdeaCentre

This OWC 16GB DDR4 2666MHz module is built for the Lenovo IdeaCentre Gaming 540-15ICK. It delivers a straightforward capacity increase for that desktop without requiring configuration changes. The unbuffered non-ECC design matches the system's original memory architecture.

288-Pin UDIMM at 2666MHz CL19 1.2V

The single specification that determines fit is the 288-pin DDR4 UDIMM running at 2666MHz with CL19 latency and 1.2V operation. It conforms to JEDEC PC4-21300 standards and is backward compatible with 2133MHz and 2400MHz slots. The 2Rx8 rank organisation is factory tested for this platform.

Suits owners of the 540-15ICK seeking more

Builders upgrading a different motherboard or needing ECC error correction should look elsewhere. The module lacks a heat spreader and registered buffering, so it is not intended for server workloads or overclocked configurations requiring those features.

Questions about this item

What does the 2666MHz rating mean once this module is installed in the Lenovo IdeaCentre Gaming 540-15ICK?

The module will run at 2666MHz if the platform supports that speed; otherwise it will downclock to 2400MHz or 2133MHz automatically because the SPD includes those lower JEDEC profiles.

Which DDR4 standard and pin layout does this UDIMM use, and what speed ceiling does that impose?

It is a 288-pin DDR4 PC4-21300 unbuffered non-ECC DIMM, so the JEDEC ceiling for this density is 2666MHz at CL19.

Will the 288-pin stick physically fit the memory slots in the IdeaCentre Gaming 540-15ICK without a heat spreader?

Yes, the 288-pin UDIMM form factor matches the desktop DIMM slots in that chassis, and the low-profile design without a heat spreader clears standard CPU coolers.
