8 GB DDR4 2400 MHz SODIMM for ThinkPad A485 and E495

This 8 GB module uses 260-pin DDR4 SO-DIMM form factor and runs at 2400 MHz with CL17 timing at 1.2 V. It is built as a single unbuffered non-ECC stick using major-brand chips and is validated for Lenovo ThinkPad A485 and ThinkPad E495 notebooks.

Sustained-load behaviour with CL17 17-17-17 timing

The module operates at standard JEDEC voltage without a heat spreader so thermals depend on the laptop chassis airflow. Under continuous workloads all installed memory will run at the speed of the slowest module or the processor memory controller limit. Matched-pair installation is recommended by the manufacturer to maximise throughput.

Check your ThinkPad configuration before ordering

The platform supports a maximum of 32 GB across two SODIMM sockets so verify how many slots are free and whether the existing stick matches 2400 MHz CL17 specs. A 64-bit operating system is required to address more than 4 GB of total memory. Mixing brands is possible but the system will downclock to the lowest common denominator.

Questions about this item

How much power does the 1.2 V DDR4 module draw when the ThinkPad A485 or E495 runs all day?

It operates at the standard DDR4 voltage of 1.2 V, so power draw stays low during continuous use.

What must the laptop already have for this 260-pin SODIMM to work?

A free DDR4 SO-DIMM slot and a 64-bit operating system to address the full 8 GB.

Will the CL17 timing slow down if I keep the original memory in the second socket?

All installed modules run at the speed of the slowest one, so mixing can reduce overall performance.
