Possible Reasons for the Warzone Memory Error 0-1766

Insufficient RAM: Is your PC too old or has not been upgraded for soo long? If yes, you need to get the configuration of your PC checked. Like every game, even Warzone comes with specific RAM requirements. If your PC does not have the required RAM to play the game, you might encounter a 0-1766 memory error.

Poor Internet Connection: Check your internet connection speed before looking for any solutions to fix the error. In most cases, poor internet connection was responsible for the memory error in the game. In case your wireless internet connection is unstable, connect your system to LAN and check if the game works fine.

Corrupted Game Files: If some of the game files are missing in the installation folder or if they are corrupted, you are likely to face errors in the game. For this, you can scan the game files and repair the missing or corrupted files to play the game smoothly.


Background Applications: If you have multiple applications running in the background, a few applications might impact the game’s performance. You need to close all the background applications.

Outdated Graphics Driver: Just like the RAM, Warzone has a specific requirement for the graphics. If your graphic card is not compatible with the settings of the Warzone game, then the game might not function properly. You need to upgrade the graphics driver or the card itself.

Now that you know the possible reasons that are hampering your game’s performance, let’s check out the quick and working solutions to fix the memory error in Warzone.

How to Fix Warzone Memory Error 0-1766?

Here are some of the working solutions:

If the internet connection is poor, follow either of these solutions and see if the problem is resolved:

Limit the Active Connections: If multiple devices are connected to the same internet, then disconnect some inactive devices, as they might be consuming too much of your internet bandwidth.

Use an Ethernet Cable: Wired connections usually provide more stable internet speeds than WiFi connections. So, if you are facing internet speed issues over the WiFi, switch to the LAN connection and check if the internet connection is stable or not.

Restart the Router: If you have tried both the solutions above and if it did not work, restart the router. You can do this by plugging off the cables and power cord and waiting for at least 60 seconds before you re-plug the wires.

Tips to Play Warzone Games Smoothly

To make sure you have a lag-free and error-free Warzone game experience, follow these simple tips:

  • Make sure you have a good RAM size (preferably the latest version and more capacity): As the games get bigger in file size with every installation, it is important to have a good RAM memory.
  • Invest in a dedicated graphic card: Games like Warzone are graphic intensive and require a very good graphic card that can produce high-quality visuals on the screen and provide a lag-free gaming experience. Though the initial investment for a graphics card is more, the experience it gives you while gaming cannot be explained in words.
  • Have a Good Internet Connection: Installing a high-speed internet connection at your home solves half of the problems related to the game. Players often experience a lag in the game or any errors due to poor internet connection. Also, make sure to buy a good router that has the capability to produce good signal strength (for WiFi) while gaming.
  • Close the game Properly: Abruptly closing the game after playing will corrupt the cache files, eventually leading to many errors. So, as soon as you finish the game, it is recommended to close it properly.
