System-specific DDR4 upgrade

This 8 GB DDR4 SODIMM is built for Lenovo Legion Y520-15IKBA and Y520-15IKBM laptops. It delivers 2133 MHz speed with CL15 timing at 1.2 V in a single unbuffered module. The 260-pin form factor matches the factory slots exactly.

Sustained-load behaviour

Dual-rank 2Rx8 organisation spreads workload across two 64-bit ranks for steadier throughput during long sessions. Non-ECC operation keeps latency low while the major-brand chipset maintains stability at the rated 17000 transfer rate. No heat spreader means airflow in the chassis handles cooling directly.

Pre-installation checks

Confirm your model is one of the two listed Legion variants before ordering. The platform supports up to 32 GB across two sockets, so verify how many slots are free and whether existing modules match the 2133 MHz specification. Mixing speeds will force all memory to run at the slowest installed rate.

Questions about this item

How much heat does the 1.2V DDR4 2133 MHz module produce during all-day use?

The module runs at 1.2 V without a heat spreader, so it generates minimal heat and no audible noise during continuous operation.

What must the laptop already have for this 260-pin SODIMM to work?

Your Lenovo Legion Y520-15IKBA or Y520-15IKBM needs a free DDR4 SO-DIMM slot that accepts 260-pin unbuffered non-ECC memory.

Will this CL15 stick run correctly if the other slot holds the original Lenovo memory?

Yes, the 2Rx8 CL15 2133 MHz module is designed for the Y520-15IKBA and Y520-15IKBM and will operate at the system's supported speed alongside the factory stick.
