8GB DDR4 SODIMM for Lenovo Legion

This 8GB DDR4 2666MHz SODIMM module is built for owners of Lenovo Legion Y530 and Y730 laptops who need a straightforward memory upgrade. It uses a 260-pin layout and runs at 1.2V without ECC or buffering. The single stick delivers 8GB of capacity for everyday multitasking and general workloads.

Sustained-load behaviour with CL19 timing

Operating at CL19 19-19-19 timings, the module maintains consistent throughput during extended sessions rather than only in short bursts. The unbuffered design keeps latency predictable across repeated read and write cycles. All installed memory will run at the slowest module speed, so matching pairs are recommended for dual-channel throughput.

Check your Legion model and OS before ordering

Verify that your laptop is one of the listed Legion Y530-15ICH, Y530, Y730, Y730-15ICH or Y730-17ICH variants. The system supports a maximum of 32GB across two sockets, so confirm an empty slot is available. A 64-bit operating system is required to address more than 4GB of total memory.

Questions about this item

Does the 1.2 V DDR4 module run cooler than higher-voltage memory during long sessions?

The module operates at the standard DDR4 voltage of 1.2 V, so it draws the same power as other DDR4 SODIMMs and produces no extra heat.

Must my laptop be a Lenovo Legion Y530 or Y730 model for this SODIMM to work?

The stick is validated for Lenovo Legion Y530-15ICH, Y530, Y730, Y730-15ICH and Y730-17ICH; other systems are not guaranteed.

If I keep an existing module in the second slot, will both sticks run at the slower module's speed?

All installed memory runs at the speed of the slowest module or the CPU's memory-controller limit.
