8GB DDR4 2666MHz SODIMM for Lenovo Legion Y740

This Computer Memory Solutions module provides 8GB of DDR4 memory at 2666MHz with CL19 timings. It uses a 260-pin SO-DIMM form factor and operates at 1.2V. The unbuffered, non-ECC stick is built with major-brand components and carries the supplier's lifetime warranty when purchased directly.

Suits Legion Y740 15 and 17 owners adding capacity

This module is validated for Lenovo Legion Y740 (15) and Lenovo Legion Y740 (17) laptops. Builders needing ECC error correction or registered signal buffering should look elsewhere, as this stick provides neither. Systems limited to speeds below 2666MHz will downclock the module, and buyers wanting a heat spreader will not find one here.

2666MHz speed with CL19 latency

The decisive specification is the DDR4 2666 (PC4 21300) rating combined with 19-19-19 timing. If your Legion Y740 requires a different speed grade or lower latency, this part will not match the required profile.

Questions about this item

How much heat or power does the 1.2 V DDR4 SODIMM draw when the Legion Y740 runs all day?

The module operates at the standard 1.2 V DDR4 voltage with no heat spreader, so thermal output is low and typical for unbuffered laptop memory.

What must my Lenovo Legion Y740 (15 or 17) already have for this 260-pin stick to work?

Your laptop needs a free 260-pin DDR4 SO-DIMM slot; the Legion Y740 15 and 17 each provide two sockets supporting up to 64 GB total.

Will this CL19 2666 MHz module run stably alongside the original memory in my Legion Y740?

Yes, it matches the factory DDR4 2666 specification and 1.2 V voltage, so it will sync with the existing stick at the system’s default speed.
