Upgrading DDR4 RAM on the Lenovo ThinkCentre M75q Gen 2 Mini PC

In my video tutorial, viewers learn how to upgrade the RAM on a Lenovo ThinkCentre M75q Gen 2 small form factor (SFF) desktop PC. The creator demonstrates the process step by step, using a 32GB DDR4 3200MHz Silicon Power SO-DIMM memory module SP032GBSFU320X02. Although these modules are commonly used in laptops, they are fully compatible with this compact desktop. The video begins with a careful unboxing and a reminder that rising memory prices make upgrades more valuable than ever.

The tutorial continues with a detailed guide on how to safely disassemble the solid metal case. After powering off and unplugging the computer, remove the Wi-Fi antenna and the securing screw before sliding off the top and bottom covers. Once opened, you can clearly see the two RAM slots on the motherboard, one of which is free for an upgrade. The new memory is inserted into the empty slot, aligned properly, and pressed down until it clicks into place.

After the installation, the system is reassembled in reverse order. To verify the upgrade, the creator uses Lenovo Diagnostics, accessed by pressing Enter and then F10 during startup. The tool confirms that the system now recognizes forty gigabytes of total RAM, a combination of the original eight gigabytes and the newly installed thirty-two gigabytes module. The video also demonstrates a quick memory test to ensure the new module works correctly, followed by a check inside Ubuntu 24.04, where the RAM is correctly reported.

Conclusions

• ThinkCentre M75q Gen 2 supports DDR4 RAM at 3200 MHz and dual channel configuration.
• The system can be upgraded to a maximum of 64 GB of RAM.
• Installing additional RAM is straightforward, safe, and significantly improves system performance.
• Laptop-style SO-DIMM modules are compatible, making upgrades affordable and accessible.
