System-Specific DDR4 Upgrade

This 8 GB SODIMM module is built for Lenovo Legion Y530 and Y730 laptops. It delivers a single 260-pin stick rated at DDR4 2666 (PC4 21300) with CL19 timings and 1.2 V operation. The unbuffered, non-ECC design matches the factory specification for these models.

Sustained Workload Behaviour

Major-brand chips and a 1Rx8 layout provide stable throughput during extended gaming or rendering sessions. The module runs at standard JEDEC voltage without a heat spreader, relying on the laptop’s existing cooling to maintain consistent performance under load.

Upgrade Context

This part adds 8 GB to systems that support up to 16 GB across two sockets. It suits owners of compatible Legion laptops who currently run a single module and want to reach the platform maximum. Buyers needing more than 16 GB or a second stick for a four-slot desktop board should look elsewhere.

Questions about this item

How much heat or power does the 1.2 V DDR4 2666 MHz module draw during all-day use?

The 1.2 V DDR4 2666 MHz SODIMM runs at standard low voltage, keeping heat and power draw minimal during continuous operation in compatible Lenovo Legion laptops.

What must my Lenovo Legion laptop already have for this 260-pin SODIMM to work?

Your Legion Y530 or Y730 needs a free DDR4 SODIMM slot supporting 2666 MHz; the system max is 16 GB across two sockets.

Will this CL19 8 GB stick run correctly alongside the original memory in my Legion Y530-15ICH?

Yes, it matches the factory DDR4 2666 MHz CL19 timing, so it will operate in sync with the existing module up to the 16 GB limit.
