Go to the Dell Support site , enter your Service Tag, and click View Product Specs to see the original configuration and maximum supported RAM (e.g., 16GB, 32GB).

Before buying anything, you must know what your laptop can handle.

Laptop RAM is different from desktop RAM. Ensure the new module matches these criteria:

Look for a sticker on the bottom of your laptop or type "SupportAssist" in your Windows search bar.

It is best to match the speed of your existing RAM. If you mix speeds, the system will default to the slowest stick's speed.

Laptops use SO-DIMM (small outline) modules, which are shorter than desktop DIMMs.
