Upgrade the RAM in your IdeaPad 3 15 with this step-by-step guide

Spread the love

Lenovo’s IdeaPad 3 15 is a budget laptop with upgradeable RAM and storage, making it much easier to keep up to date in future years. I already wrote a guide on how to upgrade the SSD in the IdeaPad 3 15, and it’s now time to tackle the memory. I’ll guide you through the required steps and offer some upgrade hardware recommendations to make the process as easy as possible.

How to upgrade RAM in the Lenovo IdeaPad 3 15

The IdeaPad 3 15 (model number 15IML05) is fairly easy to upgrade, though it only offers access to one SODIMM RAM slot. The laptop comes with 4GB of RAM soldered to the board no matter what, with another stick installed in an easy-access manner for dual-channel performance.

The laptop uses DDR4-2666MHz RAM from the factory, which is quite easy to find and match up. It’s up to you how much RAM you want to add to the laptop, but I don’t think going above 12GB makes much sense for a 10th Gen Core i3 processor. You can check out our ultimate RAM buyer’s guide for a deeper dive into the subject.

For this case, I recommend checking out something like XPG’s Premier RAM. It’s about as affordable as memory gets, costing about $32 for an 8GB stick. With the 4GB soldered to the board, that’s a total of 12GB.

Upgrading RAM shouldn’t cause system issues, but it’s never a bad idea to back up all your data before tinkering. Our guide with six easy and effective ways to back up your PC has all the information you need to get the job done.

Once your data is safe and you have a new stick of RAM in hand, clear out a well-lit workspace, power down your IdeaPad 3 15, and follow these steps.

  1. Unscrew the 10 fasteners on the bottom of the laptop using a Phillips-head screwdriver. Note that the front screws are shorter than the rest. Also, keep them separated for reassembly.

  5. Slide the new RAM into the slot at about a 25-degree angle. Both the RAM and the slot are keyed and will only fit together one way.
