Free RAM is not synonymous with performance

Published on May 04, 2026 | Translated from Spanish

There is a belief that the more free RAM we have, the better our PC will perform. The reality is the opposite: modern operating systems use that spare memory to cache frequently used data, speeding up processes. Leaving it free is not optimization, it is wasting a resource you already paid for. In games, this idea can be counterproductive.

Illustration of a PC with a RAM meter 80% full, showing icons of games and apps loading quickly, with text: Full RAM = speed.

The deception of memory optimizers 🧠

RAM optimizer programs often promise miracles, but their operation is simple: they force the system to aggressively free up cache memory. In doing so, they remove preloaded data that the game or application constantly uses. The immediate result is a false sense of relief, followed by micro-stutters or FPS drops when the title has to reload that data from the disk. You are not optimizing, you are slowing down access to information.

The myth of the magical RAM cleaner 🪄

It's curious to see someone pay for software that cleans RAM and then boast about having 8 GB free while their game runs at 15 FPS. It's like buying a sports car and complaining that the engine makes noise, so you turn it off to save fuel. The system already knows how to manage its memory better than a magic button. The only real optimization is closing Chrome before gaming, not using a program that sells you smoke.
