1. Basic Troubleshooting
Before we explore more complex solutions, let’s start with some basic troubleshooting steps.
2. Clear the Platform’s Cache
If invalid configurations and entries are stored in the cache of your gaming platform, MW3 might encounter the 12707 memory error during gameplay, as it fails to correctly process the cache’s entries. Clearing the cache can resolve this error.
2.1. For PS5
2.2. For Xbox
2.3. For PC
The method to clear the game’s cache varies depending on your launcher. For Battle.net, follow these steps:
3. Open MW3 and Its Launcher as an Administrator
MW3 may generate the memory error if the game or its launcher lacks administrative access to protected system resources. Running both the game and its launcher as an administrator can rectify this issue.
4. Log in Using Another Account
If there is an issue with your account’s authorization with the game, MW3 may display the memory error 12707. Logging in with a different account and then switching back to your original account can solve this problem.
5. Don’t Edit Loadouts During a Match
Editing a loadout during a match may cause MW3 to improperly implement the changes and result in the 12707 memory error. Avoid modifying loadouts while a match is active to prevent this issue.
6. Reinstall COD Modern Warfare 3
A corrupted game installation or malfunctioning core modules can cause MW3 to exhibit the 12707 memory error. Reinstalling MW3 is likely to fix this problem. Note: MW3 cannot be uninstalled independently at the moment, meaning you will also need to uninstall MW2 along with COD HQ. Redownloading these may consume significant time (depending on internet speed) and data (200+ GB).
