8GB DDR4 2400 SODIMM for ThinkPad E-Series

This 8 GB DDR4 2400 MHz SO-DIMM is built for Lenovo ThinkPad E470, E475 and E480 notebooks. It uses a 260-pin unbuffered non-ECC layout with CL17 timings at 1.2 V. Buyers needing ECC error correction or registered modules should look elsewhere.

Thermals and power at standard voltage

The module runs at the JEDEC standard 1.2 V without a heat spreader. Low voltage keeps power draw modest and heat output minimal inside the tight ThinkPad chassis. Fan noise stays governed by the laptop's own thermal curve rather than added memory heat.

Single-stick upgrade with lifetime warranty

The package contains one 8 GB stick, letting you fill a free slot or replace an existing module up to the platform's 32 GB two-socket limit. Computer Memory Solutions backs the part with a limited lifetime warranty against manufacturing defects when purchased directly from them. Product appearance may vary from the reference image.

Questions about this item

How do I install this 260-pin DDR4 SODIMM into a ThinkPad E470, and which step causes the most problems?

Power off the laptop, remove the bottom cover, line up the notch on the module with the slot key, insert it firmly until the gold contacts disappear, then press down until the side clips snap into place; the step most people miss is pushing hard enough to fully engage both clips.

What maintenance or replacement will this 8 GB CL17 module need over its lifetime?

No scheduled maintenance is required; if a fault appears, the manufacturer offers a limited lifetime exchange against manufacturing defects when purchased directly from Computer Memory Solutions.

What limit appears first when this 2400 MHz memory runs sustained workloads on an E475?

The platform caps memory at 32 GB across its two slots, so capacity ceiling is reached before any speed or thermal throttle from the 1.2 V unbuffered modules.
