System-specific DDR4 SODIMM for ThinkPad

This 8 GB DDR4 SODIMM is built for Lenovo ThinkPad E575, E585 and L380 notebooks. It targets users who need a single-module upgrade to reach the platform’s 32 GB ceiling without mixing kits.

Unbuffered 260-pin layout with major-brand chips

The stick uses a standard 260-pin SO-DIMM edge connector and unbuffered 2Rx8 organisation, so it drops into the factory slot with no adapters or BIOS tweaks. Absence of a heat spreader keeps the profile low for cramped chassis bays.

1.2 V operation at 2400 MHz with CL17 timing

Rated at 1.2 V and PC4-19200 speed, the module runs at stock voltage and latency, producing minimal extra heat and fan noise during typical workloads. Non-ECC design suits mainstream productivity and web use.

Questions about this item

What does the DDR4 2400 (PC4 19200) interface mean for real-world speed?

The DDR4 2400 interface runs at 2400 MHz with a PC4 19200 bandwidth rating. CL17 timing and 1.2V voltage define the latency and power envelope for this 8 GB SODIMM.

Will the 260-pin SO-DIMM fit my ThinkPad E575, E585 or L380?

Yes. The module uses the standard 260-pin DDR4 SO-DIMM form factor with no heat spreader, matching the two SODIMM slots in those ThinkPad models.

How do I install the stick and what is the common mistake?

Power off, open the memory door, align the notch on the 260-pin edge connector, insert at an angle, then press down until both clips click. The frequent error is stopping before the clips fully engage.
