Upgrading RAM in a Desktop or Laptop

Adding RAM is one of the most cost-effective hardware upgrades for a slow computer. Before purchasing RAM, check the system's specifications: maximum supported RAM, number of available slots, and required RAM type (DDR4, DDR5, speed rating like 3200MHz). Use the tool Crucial Memory Advisor (crucial.com/advisor) or CPU-Z (free) to identify compatible RAM. For desktops: shut down and unplug. Open the case, locate the RAM slots on the motherboard, press the release clips at each end of the existing module to pop it out. Insert the new module(s) at a slight angle, press firmly until both clips snap into place. For dual-channel performance, install matching pairs in the specified slots (usually slots 1 and 3, or A1 and B1 — check the motherboard manual). For laptops: the bottom panel must be removed (usually held by Phillips screws). RAM slots are typically visible after panel removal. Some modern ultrabooks have RAM soldered to the motherboard and cannot be upgraded — check before purchasing. After installation, boot and verify the new RAM is recognized in Task Manager > Performance > Memory.
