16 GB DDR4 SODIMM for ThinkPad A475 E580 L470

This 16 GB DDR4 2400 MHz SODIMM module is built for Lenovo ThinkPad A475, E580 and L470 notebooks. It suits users who want to reach the 32 GB maximum supported by these systems with a single stick. The unbuffered, non-ECC design matches the original specification for everyday workloads.

Check your ThinkPad model and slot count

Verify that your laptop is a ThinkPad A475, E580 or L470 before ordering. These models have two SODIMM slots and support up to 32 GB total, so a single 16 GB module works whether you are adding to an existing stick or starting fresh. The module runs at 1.2 V with CL17 timing, matching the factory configuration.

260-pin unbuffered module without heat spreader

The stick uses a standard 260-pin DDR4 SO-DIMM edge connector and major-brand chips in a 2Rx8 layout. No heat spreader is fitted, keeping the profile low for tight laptop chassis. Installation is a simple slot-in action; the unbuffered design means no extra BIOS steps are required for the memory to be recognised.

Questions about this item

Does the module ship as a single 16 GB stick or do I need to buy a second one to reach 32 GB?

The kit contains one 16 GB DDR4 2400 CL17 SODIMM; a second identical stick is required to reach the 32 GB maximum supported by the ThinkPad A475, E580 or L470.

Should I choose the 16 GB version or a smaller capacity for my ThinkPad L470?

The 16 GB module fills one of the two slots and leaves room for another 16 GB stick to hit the 32 GB ceiling; smaller capacities are only useful if you plan to keep an existing module.

Will the advertised 2400 MHz speed run at that rate inside a ThinkPad E580?

The module is rated DDR4 2400 (PC4 19200) at 1.2 V with CL17 timing; the ThinkPad E580 memory controller will operate it at that speed provided the BIOS is current.
