System-Specific DDR4 Kit

This 32GB kit contains two 16GB DDR4 SO-DIMM modules rated at 2400MHz with CL17 timings. It is built for Lenovo ThinkPad E480, E485, E560p and E570 notebooks that accept 260-pin unbuffered non-ECC memory. The 1.2V operating voltage matches the standard platform requirement.

Upgrade From Lower Capacity

The kit replaces the factory-installed modules to reach the platform maximum of 32GB across two sockets. The jump is worthwhile when the current configuration limits multitasking, virtual machines or large dataset handling. It is not for systems limited to 16GB total or those requiring ECC or registered DIMMs.

Sustained Load Behaviour

Without a heat spreader the modules rely on the notebook's internal airflow to manage thermals during extended workloads. The major-brand chipset and unbuffered design maintain the rated 17-17-17 timings at 1.2V under continuous operation. Stability is validated for the listed ThinkPad models under prolonged memory-intensive tasks.

Questions about this item

Will the 260-pin SODIMM modules fit the two memory slots in my ThinkPad E480, E485, E560p or E570?

Yes, the kit provides two 16 GB DDR4 2400 CL17 sticks that match the 260-pin SO-DIMM form factor used by those models.

What is the correct way to seat the modules so they lock in place?

Align the notch on each stick with the key in the slot, insert at an angle, then press down evenly until the side clips snap into the notches on both edges.

Do these unbuffered non-ECC sticks require any firmware updates or periodic replacement?

No firmware update is needed; the modules run at 1.2 V with standard JEDEC timings and are covered by the manufacturer’s limited lifetime warranty against defects.
