This flag allows a 32-bit application (like Ghosts ) to address up to 4GB of memory instead of the default 2GB. It does reduce memory usage—it simply lets the game use the full amount of RAM you have. Important: This works best on 64-bit versions of Windows 7, 8, 10, or 11 with exactly 4GB of physical RAM. Download the 4GB RAM Patch (Safe & Verified) Do not download random .exe files from unknown forums. Many “fixes” contain malware.

If you’ve been trying to run on a system with only 4GB of RAM, you’ve likely run into a frustrating wall: stuttering, freezing, or the game refusing to launch altogether with a low-memory error.

Happy hunting, Ghosts.

Released in 2013, Ghosts was notoriously demanding for its time. The game’s minimum requirements call for 6GB of RAM. But does that mean 4GB users are locked out forever? With the right patches and configuration tweaks, you can get the game running smoothly.

For multiplayer, consider upgrading to 8GB (often $20-30 used). But for the story mode, this fix is a lifesaver. Let us know your results in the comments below.
