AC Odyssey Random Freeze while in-game (Hard-reset required)

Good day

Im running Windows 10 64-bit Version 1903.

So i have played AC Odyssey for 400+ hours and in that time i've only had 3 crashes.

The first two were CTD with no error messages but they were minor and they were weeks apart between both errors and put it down to nothing more than random crashes.

My latest one was a freeze while playing the game. It happened on the evening of 23/03/2020 around 19:30. I had played for round about one hour when it happened. The only way to get out of the crash was to do a hard reset of my system.

I bought the game through Steam but obviously Uplay application needs to be up as well.

So this is what i did after that particular crash:

1. Disable Uplay in-game overlay (had read somewhere might have reason for crashes)
2. Played for 3+ hours again while monitioring temperatures (GPU never got beyond 80 degrees celcius while CPU temperatures never got higher than 75 degrees celcius)
3. Ran Memtest86 using standard 4-pass test. Took about 3 hours with no errors.
4. Updated my GPU drivers which were month out of date.

The log file in event viewer and error log file for ubisoft logging dont really show anything untoward or anything particular.

What strange is that it would all of a sudden just hang and have never experienced anything like this while running this game and it is difficult to replicate cause its never happened before.

Is there any other testing i can do relating to RAM, CPU and GPU? On the surface it looks more like software issue but cant be sure.

Please advise on anything additional that can be done.

Thank you.

Thank you for these diagnostic tools.

After using a few of them im quite happy that my issue was nothing more than a random crash not attributable to hardware.

Thanks again.

Unless you are overclocking I wouldn't run any of those CPU stress testing tools. In fact I see nothing in your post to even warrant the suggestion of running any CPU stress tools. And the fact that you're getting freezes requiring hard resets, the last thing you want to do is run CPU stress testing tools!!!.

And my question to @MrPepka is what's next when the tests fail due to some other issue other than overclocks? Also, how are you going to tell someone to stress test their system with such back breaking tools when you don't even know the OP is even overclocking

There's nothing in the OP's post to warrant such drastic measures. In fact I consider the suggestions counterintuitive.

@Coach81, is AC the only game giving you such issues?

AC Odyssey was the only time i ever got this problem.

I dont use any overclocks either.

Like i mentioned at the beginning of the post in over 400hrs of gameplay this was the first such occurence of this issue.

My system is relatively new and right now im putting this error down to something other than hardware as i actually dont believe it to be so. However i am open to any other suggestions that can rule out that possibility.

Answer this... do you overclock? Do you know how to adjust BIOS settings?

These are questions that should be asked before running hardcore stress tools like Prime95 which can burn out a CPU if not adequately cooled. Same with FurMark in stressing your GPU. If you're going to run those programs you'd better have good cooling!

That said, based on the info you provided, along with your last reply there's no need to run those programs; especially if you're unsure of how to use Prime95.

Good luck.

Yes, no overclocks used.

I never used Prime95 cause i know thats its too demanding so i never went near it.

Thank you for the help, my issue was just extremely random and was curious as to what actually caused it but until the problem is replicated in future i cant be 100% certain.

Cheers

If any of the tests fail, it will be the basis for believing that the problem is hardware. Tests may fail even if the OP did not overclock any component (e.g. when the power supply does not demand or if, for example, the processor overheats during the test because of dried thermal paste etc., etc.). This should not be approached zero-one on the principle "If the tests fail, the processor or graphics card must be overclocked"

I am currently occasionally playing AC Syndicate from 2015, I'm 5 years behind everyone else...
One crash to the desktop on that one in around 2 weeks. Through the Epic games client/Uplay.

The Epic games client is a lot worse than AC, many times in the Windows Reliability report.

Have also played 2 of the older AC titles.

All of them have the odd bug here and there, and some rare crashes out. Some titles are apparently worse than others.
Getting trapped in or behind scenery is what I have seen most of.

You have done sufficient tests, no worries.
