Compatible ThinkPad Memory Upgrade

This 32 GB kit provides two 16 GB DDR4 SO-DIMM modules rated at 2400 MHz with CL17 timing. It is built for Lenovo ThinkPad E575, E580, E585 and L380 notebooks that accept 260-pin unbuffered memory. The 1.2 V modules install directly into the two available slots.

Suitable For Standard Capacity Limits

The kit fills both sockets to the 32 GB maximum supported by these models. Users who need more than 32 GB of system memory must choose a different platform. Buyers with laptops outside the listed ThinkPad series should verify compatibility before purchase.

Steady Operation At Rated Speed

Running at 2400 MHz with 17-17-17 timings, the modules maintain their specified latency and voltage during extended workloads. The unbuffered design and major-brand chipset deliver consistent throughput for typical multitasking and productivity tasks without thermal throttling.

Questions about this item

Does my ThinkPad E575, E580, E585 or L380 need two free 260-pin DDR4 SODIMM slots to install this 32 GB kit?

Yes, the kit contains two 16 GB modules and the listed models have two DDR4 SODIMM sockets, so both slots must be available.

Can I keep one existing 16 GB DDR4 2400 MHz stick and add only one module from this kit?

You can, but the remaining slot would hold a single 16 GB stick, giving 32 GB total; matched pairs are recommended for dual-channel performance.

After installation, how do I confirm the memory runs at DDR4 2400 with CL17 timings?

Open Task Manager or a tool such as CPU-Z; the speed should read 2400 MHz and the timings 17-17-17.
