The Lenovo ThinkCentre M720q Tiny is an awesome little desktop PC, designed to be not much larger than an old optical drive yet containing an M.2 PCIe solid-state drive (SSD), 2.5-inch hard drive, and dual SODIMM RAM slots, all upgradeable after purchase. If your model didn't come with enough RAM for the tasks you're running on the M720q, this guide will walk you through the process of adding more.

Hardware to get the job done

How to upgrade RAM in your Lenovo ThinkCentre M720q

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.

Lenovo's ThinkCentre M720q Tiny, alongside upgradeable M.2 SSD, and 2.5-inch drive, has two slots for DDR4 SODIMM RAM, accessible through a bottom panel on the PC's chassis. You can configure a model with up to 32GB of RAM straight from the factory, but if you'd like to save some money at checkout or don't initially need quite as much, you can go as low as 4GB from a single stick.

As an upgrade or addition, we recommend Crucial DDR4-2666MHz RAM for its reliability, competitive price, and availability in sizes ranging from 8GB up to 32GB. There should also be no compatibility issues with your system.

Once you have the upgrade RAM ready to go and have made any data backups to safeguard when taking apart the PC, power down the ThinkCentre M720q and clear out a well-lit workspace. It's time to upgrade! Our M720q model came with just one stick of SODIMM RAM, leaving the other slot free, but the steps remain the same for taking apart the PC, removing old RAM, and installing new RAM.

  1. Unscrew the large black fastener on the back of the ThinkCentre M720q.

    Unscrew the fastener.

  2. Slide the top and front portions of the chassis cover away from the rear. It should separate with relative ease.

    Slide off the top and front panels.

  3. Turn the M720q over to reveal another removable panel.

    Flip the device over.

  4. Slide the bottom panel away from the rear of the device. It should come away with relative ease.

    Slide off the bottom panel.

  5. Slide the silver arms off of the first stick of RAM. Upon releasing both clips, the RAM should pop up and remain at an angle.

    Slide the silver arms off of the RAM.

  6. Remove the RAM from the slot by carefully pulling it away.

    Slide the RAM out of its slot.

  7. Insert the new RAM into the slot at about a 45-degree angle. Notice it is keyed and will only fit one way.

    Insert the new ram into the slot.

  8. Press down on the RAM until it clicks into place. You should see both silver arms clip back into place to hold the RAM securely.

    Press down on the RAM until it clicks into place.

  9. Slide the bottom panel back onto the M720q main chassis.

    Slide the bottom panel back onto the chassis.

You should now be free to power on your ThinkCentre M720q Tiny to ensure the RAM upgrade went according to plan. You can check to see if it's been recognized by your system with the following steps.

  1. Right-click the Start button.
  2. Click System.

You should now be able to see the total amount of installed RAM in the Device specifications section. As long as it matches the total amount you have installed, your upgrade was a success.
