The immensely successful COD franchise continues to churn out content and updates like an angry volcano made of guns.

If Warzone has thrown this error-shaped grenade your way, then consider us the trusty body armour to protect you from it detonating. Here is what we know about error code 0 1766.

What is Memory Error 0 1766?

  • Microsoft recommend closing any games or apps that may be running in the background. To do this, go to your Home screen. Navigate to your most recently run game and highlight it. Press the Menu button, and select Quit.
  • You can also try clearing the Mac address. For this:
    • Go to Settings > Network Settings > Advanced Settings > Alternate Mac address > Clear it
    • The console should then restart. It's also advised that you restart your internet router while the console is restarting
  • Some players have found that restricting their game resolution to 1080p has also somehow resolved the error.
  • Others have found that turning off HDR has also helped.

Will this fix everything?

Again, while we can't guarantee these tips will work for everyone, it's worth giving them a go to see if they help. Otherwise, it's a case of waiting for Activision to figure out the problem and provide a solution.
