Compatible ThinkPad DDR4 SODIMM kit

This 16GB kit contains two 8GB DDR4 SODIMM modules built for Lenovo ThinkPad E575, E580, E585 and L380 laptops. It uses 260-pin unbuffered non-ECC memory running at 1.2V. The kit is designed as a direct upgrade for those specific models.

DDR4 2400 CL17 timing

Each module operates at DDR4 2400 speed with a CAS latency of 17 and 17-17-17 timings. The PC4 19200 rating matches the memory controller requirements of the listed ThinkPad systems. Major brand chipsets are used to maintain stability.

Ideal for E575 E580 E585 L380 owners

This kit suits users upgrading a compatible ThinkPad to 16GB across two slots. Buyers needing 32GB total capacity should verify their model supports that maximum. Anyone with a different laptop or a desktop motherboard cannot use these SODIMM modules.

Questions about this item

What does the DDR4 2400 speed rating mean once the modules are installed in a ThinkPad E575, E580, E585 or L380?

The kit runs at 2400 MHz with CL17 timing and 1.2 V. The laptop's memory controller will set the final operating frequency, which cannot exceed 2400 MHz.

How does the 260-pin SO-DIMM interface limit the usable bandwidth on these laptops?

The 260-pin DDR4 SO-DIMM socket caps transfer rate at the PC4 19200 (2400 MT/s) rating of the modules; the platform cannot push data faster than that interface allows.

What physical space is needed inside the ThinkPad to fit the two 8 GB sticks?

Each module is a standard 260-pin SO-DIMM without a heat spreader, so they occupy two adjacent SODIMM slots in the laptop's memory compartment.
