Factorio Forums

Hi,
i wanna start a new map, i got some bluescreens while tryin to preview maps in singleplayer so i decided to go to multiplayer to create a map...

then i got a "Unexpected error occurred"

Some QoL Mods, Krastorio 2, Space exploration

If you get bluescreens, then something is wrong with your system.

yeah, but it only happens in factorio. it said i should share it, so there you are.

And also not only in factorio, it also ONLY happens while creating a preview of a map.

I think that preview map generates using multiple threads so if it causes blue screens you could run some tests to load CPU and check if they will also cause problems.

Yeah again like 100 hours in a game without a single crash. I literally had to use a different computer to generate a map for me

Maybe a dev can tell what makes the preview method so special? Does it use different instructions?

It eats CPU cores for breakfast :)


You can try reducing the used thread count: Main menu -> ctrl + alt click on settings -> the rest -> search for max-map-preview-threads -> decrease the number.

Thanks, ill give it a try.

But i tested my OC with prime95, does it maybe use AVX (or what ever its called?) this special thing no program normal uses xD

Virtually every program out there uses SIMD including the operating system and the browser you're using to post here.

The bottom line is: if you experience a BSOD then your hardware is unstable. That's caused by: bad overclocks, bad hardware, or bad drivers.

that's software

not all SIMD use is equivalent or Prime95 wouldn't be capable of such excessive power consumption. Furmark has its own nasty way with things.

either way, not helpful info since it's not even accurate

c05 error is accessing invalid memory, which means Factorio is doing something it shouldn't. probably a use-after-free in some threaded code.

btw you have a really nice system and i'm kind of jealous

Drivers are kernal space software. User space software does not have access to anything that can cause a BSOD.

It's not. It's a unstable system executing code that has been corrupted by an unstable CPU overclock. I and multiple coworkers have that exact same CPU and have been running it for quite some time with zero issues. If there was any issue with the code that's running we would see it in the crash logs and they show there is no issues around that area of code.
