Targeted laptop upgrade

This 8 GB DDR4 SO-DIMM module is built for Lenovo ThinkPad T480s, ThinkPad Yoga 260 and V330 15 laptops. It suits owners who need a single stick to fill one empty slot or replace a failed unit. Buyers whose machines require ECC memory or a different pin count cannot use this part.

Critical compatibility spec

The module runs at DDR4 2400 (PC4 19200) with a CL17 17-17-17 timing at 1.2 V. It is unbuffered, non-ECC, dual-rank 2Rx8 and uses a 260-pin edge connector. Only systems that accept this exact speed, voltage and pin layout will recognise the stick.

Sustained workload behaviour

Under continuous load the DRAM operates at the rated 1.2 V without a heat spreader, relying on the laptop’s internal airflow. The major-brand chipset and lifetime warranty from Computer Memory Solutions indicate stable operation during extended sessions. Systems limited to lower speeds will down-clock the module automatically.

Questions about this item

What does the 2400 MHz DDR4 speed mean once the module is installed in a ThinkPad T480s?

The module runs at DDR4 2400 (PC4 19200) with CL17 17-17-17 timing at 1.2 V, delivering the rated bandwidth when the laptop memory controller is set to that speed.

Which SO-DIMM interface does this kit use and what does it cap in practice?

It uses a 260-pin DDR4 SO-DIMM interface, unbuffered non-ECC, so the practical ceiling is the DDR4 2400 data rate supported by the ThinkPad T480s, Yoga 260 or V330 15 memory controller.

What physical slot and clearance does the 8 GB stick need to fit in the V330 15?

A single 260-pin DDR4 SO-DIMM slot with no heat spreader, matching the two sockets available in the listed Lenovo models.
