16GB DDR4-2400 SODIMM kit

This 16GB kit contains two 8GB DDR4-2400 SO-DIMM modules built to 260-pin form factor. It runs at 1.2V with CL17 timings and is unbuffered non-ECC memory. The kit is validated for Lenovo ThinkPad A475, E580 and L470 notebooks.

Upgrade from 8GB or mismatched pairs

Replacing a single 8GB stick or a mixed-capacity pair with this matched 2x8GB kit enables dual-channel operation on the two-slot platforms listed. The jump is worthwhile when the system currently runs below the 32GB maximum supported capacity and shows memory pressure in typical workloads.

Suits ThinkPad A475, E580 and L470 owners

Buyers who need a guaranteed-compatible 16GB DDR4-2400 upgrade for these three models can install this kit with confidence. Builders requiring ECC, registered modules, speeds above 2400MHz or capacities beyond 32GB should look at other memory lines.

Questions about this item

Will the 260-pin SODIMM modules fit the two memory slots in my ThinkPad A475, E580 or L470?

Yes, each 8 GB stick uses the standard 260-pin DDR4 SO-DIMM form factor that matches the two slots in those models.

What is the correct way to seat the modules so the laptop recognises the full 16 GB?

Insert each stick at the same angle used by the original modules, press down evenly until both side clips latch, then power on and confirm 16 GB appears in the BIOS.

If a module fails years from now, what replacement option does the maker offer?

Computer Memory Solutions provides a limited lifetime exchange or repair warranty against manufacturing defects when purchased directly from them.
