COD Warzone 0-1766 memory error is confusing Xbox users (workarounds)

New updates are added at the bottom of this story …….

The original story (published May 26, 2021) follows:

COD: Warzone is still one of the most popular battle royale games in the world thanks to the regular updates and fixes it receives to keep things up to date.

But it seems like updates and fixes sometimes do the opposite of what they’re supposed to, as each update brings a set of new bugs and issues that need to be addressed.

In fact, we did a poll asking readers if they noticed the various COD: Warzone Dev errors recently and 90% confirmed it was a mess. More on that here.

Having said that, many players of COD: Warzone are now reporting that they are receiving an error saying “Memory Error 0-1766” when playing the game on Xbox consoles.


@RavenSoftware glad I spent 2400 this season only to reboot from each game to my Xbox main screen with memory error 0-1766. I will not be purchasing another season while the rave software is in charge. What a warzone joke has become since the integration of the cold war. (Source)

COD: Warzone players started receiving the 0-1766 memory error message a few days ago and reports of the issue flooded Twitter, Reddit, and the Microsoft community website.

One individual even shared a screenshot of the error message. Check it out below:



Raven Software or Activision have yet to publicly acknowledge the problem. However, an Xbox ambassador on the Microsoft community has claims that Activision is aware of the problem and is supposedly working on a fix.

There is a problem between the Cold War and the Modern War. Activision is aware of the problem and is supposed to be working on a fix. I am getting the same game crashing issues after just one match and it only happens in Warzone, Rebirth and Looting.

Since the problem has not yet been officially acknowledged, it is not known how long it will take for the bug to be fixed.

Having said that, if you also get the message “Memory Error 0-1766” when playing COD: Warzone, you can try some of these workarounds which seem to have fixed the issue for some players.

Workarounds for memory error 0-1766 in COD: Warzone

A Microsoft agent shared a few generic workarounds that sometimes resolve the issue:



A few gamers who have encountered the issue claim that turning off HDR option fixes the issue for them. However, there are others who say it didn’t help. Nonetheless, it’s worth it.

Another person claimed that lowering the resolution to 1080p fixed the issue for a few turns, but it reappeared.

Set to 1080p and it worked for a few games but now memory error 0 – 1766 is back: / (Source)

That said, we will keep an eye on the situation and post an update if and when there are further developments regarding the COD: Warzone Memory error 0-1766 issue.

Remove the following:

– Data packets 1 and 2
– 4 resolution packages

Raven Software has yet to share any further details.

Update 4 (May 31)

Reports suggest that turning off 4K and HDR, followed by setting it to 1080p fixes the problem. So you can also try this workaround. This is what a user is mentionned on this subject :

Disable 4k and HDR on your Xbox, set it to 1080p, and that will fix the problem. It took the Xbox to be set up on different TVs to figure this out; the problem did not happen on my son’s 1080p tv, only on my 4k. Sad Activision couldn’t figure it out.

Update 5 (June 04)

COD: Warzone gets a new update which makes some adjustments to the playlist and even fixes a few bugs. However, the issue of memory error 0-1766 has not yet been resolved because there is no mention of a fix for it in the change log.
