BY Sourav



Call of Duty: Warzone is the most popular battle game and fun to play. But Memory error 0-1766 on Call of Duty is a major issue that many Xbox and PC users have complained about lately. The error refers to a bug for which gamers experience frequent crashes upon launch or being booted out of the game.

The worst part is the developers haven’t provided any particular solutions to fix it. Don’t fret. Luckily, it’s not too difficult to beat it. Here, we’ve outlined all the possible ways to fix the Warzone Memory Error 0-1766 to get back on the game.

Solution 1: Check the Internet Connection

Memory Error 0-1766 in Call of Duty: Warzone can be caused by an unstable internet connection. So, it’s suggested to gamers who are playing over a WiFi connection to restart their modems and routers. 

To restart a router or modem, unplug the router and modem and wait for 2-3 minutes. Then, plug back the router, wait for the connection to power on and check if the internet is working properly.

Here’re some other tips you can try:

  • Use an ethernet connection to get faster internet than WiFi.
  • Limit the number of wireless devices connected to the same network.

Solution 2. Close Background Running Apps 

If multiple apps are running simultaneously when playing Call of Duty Warzone, there can be a lack of memory space creating the memory error 0-1766. On both PC and Xbox, close all background running apps and try to start the game.

Open Task Manager on Windows to check the running apps and processes. Disable high-memory taking apps that you don’t require when playing to free some space for Warzone for error-free gaming.

Here’s the process.

For PC:

  1. Press Ctrl+Alt+Del all together and click Task Manager to open it.
  2. Under the Processes tab, you can check which programs are running in the backgroud. Select the program and choose End Task to close it.

For Xbox:

  1. From the controller, press the Xbox button to display the menu sidebar.
  2. You’ll find the list of games on the console. If a game is running, it’ll be highlighted. Choose the games or apps to close them and press the menu button.
  3. Select Quit.

Solution 3. Disable HDR

While HDR or High Dynamic Range improves picture quality with its color technology, it arises many unexpected errors.

This problem can mostly be seen on Xbox as many users have complained about encountering the 0-1766 memory error for the Auto HDR feature. PC users can also try fixing it if their device supports HDR.

On Xbox

  1. Press the Xbox button on the controller to open the guide.
  2. Go to Power and System> Settings> General> TV & display options> Video Modes.
  3. Turn off the Allow HDR option and restart your game for the changes to take effect.

  1. Select Settings> System> Display> HDR.
  2. Go to Windows HD Color Settings.
  3. Under the Display Capabilities, if YES appears beside Use HDR, select it to turn it off.

Solution 4. Decrease Screen Resolution

Call of Duty Warzone is meant to be run at 1080p full HD resolution. If you’re playing it higher than 1080p (in 4K or QHD quality), it’s another probable cause for Memory Error 0-1766. 

In that case, decrease the screen resolution by following:

  1. Go to Start> Settings> System.
  2. Select Display from the left panel.
  3. Under the Display Resolution drop-down menu, choose 1920 x 1080.
  4. Click Keep Changes to confirm it.

To make sure your Warzone game is running at 1080p, verify its in-game resolution too. For that, navigate Options> Graphics within the game. Under Render resolution, select Advanced to confirm the game’s resolution is 1080p.

Memory Error indicates a problem within the memory itself. There can be a problem with loading assets for the game from the hard drive or RAM is not sufficient to play the game. However, most of the time, the error shows up if the game files get corrupted and can’t be loaded properly. The best solution is to find and restore those files.

You can simply do a quick scan to verify the game file integrity from the launcher instead of reinstalling the entire game. Here’re the steps:

1. Launch and move to the Warzone page.
