So I loaded up my modded testing world and the game froze and crashed as soon as only about 4 chunks of the world was loaded. The crash report said it was an "Exception ticking world" what does this mean?

Ur out of ram like me right grimallq?

Accidental comment is accidental.

Quote from grimallq»

This is not something I'd call "unknown". Rather obvious even.

And use spoilers.

A. Thank you and it makes sense, as I've had memory issues a lot recently. B. Would adding 4 more gigabits of RAM to the 4 I currently have help at all? and C. How do I use spoilers?

Yes, adding 4 more Gigabytes of RAM will help your system run better.

You should also open the launcher and allocate more ram to your modded profile. Allocating 2-3GB should be plenty for your mods. If you cannot allocate 3GB due to system limitations, you're going to have to get more RAM.

I did a bit of research a week ago on allocating more RAM and have tried doing so but nothing was very clear on what to do. When I click edit profile, enable JVM arguments, and replace the amounts of RAM given there it seems to either do nothing or not work. Is there a better way to allocate more RAM? And if not, then how exactly do I do it the way I had tried?

Oh, and yeah, gigabytes. Sorry about that.

In JVM arguments, you can add/modify "-Xmx2G" to change your allocated RAM.

Ex:

-Xmx1G = 1 GB of RAM allocated

-Xmx256M = 256 MB of RAM allocated

Edit: If you're running a 32-bit machine, you cannot add anymore than 4GB to it. You need to upgrade your specs.

Okay, so from what I've picked up and tried, all I need to do now is upgrade my specs and RAM. Thank you all very much for helping!
