Hardware to get the job done

How to upgrade RAM in your Lenovo ThinkPad X1 Extreme (Gen 2)

Note: Before beginning any upgrades on a PC, it's a good idea to back up your data in the unlikely event something should go wrong. You'll also want to ensure you're not working in a static-filled environment, as it can cause damage to a PC's internal hardware. Consider investing in an anti-static wristband to avoid unnecessary damage.

From the factory, Lenovo will add up to 64GB of SODIMM DDR4 RAM to your ThinkPad X1 Extreme, but it's going to cost you nearly $1,100 more than if you check out with the baseline 8GB of RAM. That's nearly the cost of an entirely separate laptop, so upgrading yourself is a worthwhile way to spend your time.

For the upgrade we recommend checking out the Crucial SODIMM DDR4-2666MHz RAM. It's reliable, well-priced, and widely available. An extra 8GB costs about $30 while dual 32GB sticks for a total of 64GB of RAM costs about $324. That's a far more digestible price, and you can also choose from single 16GB and 32GB sticks to get exactly how much you need. Just don't buy more than 64GB, which is the max allowable RAM Lenovo recommends.

Once you have the upgrade RAM at home and ready to install, be sure to back up any important or sensitive data. This is a fairly straightforward process, but it's better to be safe. Power down the X1 Extreme, make sure your workspace is well-lit, and get ready to tackle the steps below.

  1. Unscrew the seven fasteners on the bottom of the laptop.
