Lenovo's ThinkBook 15p is a powerful 15-inch Ultrabook with 10th Gen Intel Core H-series processors (CPU), up to a NVIDIA GTX 1650 Ti, dual M.2 solid-state drive (SSD) slots, and dual SODIMM RAM slots that can be upgraded after purchase. The system uses DDR4-2933MHz RAM and might come with a single- or a dual-channel setup from the factory. In either case, upgrades are relatively easy and the entire process should take about 20 minutes to complete. Here's everything you need to know about upgrading RAM in your Lenovo ThinkBook 15p.

How to upgrade RAM in Lenovo's ThinkBook 15p

The ThinkBook 15p makes great use of space inside its aluminum body, offering up dual slots each for SSD and RAM. Most models you find will come with either a single 16GB SODIMM module for single-channel setup, or dual 8GB SODIMM modules for a dual-channel setup. That means you'll generally be looking at adding one or two 16GB modules to maximize performance. You can also add smaller modules as you like; both don't have to be the same. For example, if your device comes with one 16GB stick of RAM, you can add 8GB to the free slot for a total of 24GB.

We're not dealing with storage in this guide, but it's still a good idea to back up your data in the rare chance something goes wrong during the RAM upgrade. We have a guide that lays out six easy and effective ways to back up your PC if you need some quick tips on this front.

For upgrade RAM options, you'll want to use SODIMM DDR4-2933MHz. This will fit the laptop's RAM slots and will match up performance with existing hardware. You can check out something high-performance like HyperX Impact — about $200 for 32GB — or you can go with something more affordable but just as reliable.

You can buy one stick at a time and upgrade as budget allows, but be sure both RAM modules are the same speed and specs so they don't cause problems together. HyperX Impact is proven RAM that's worth the money.
