KSP crashing. Using too much RAM?

[Space Mailman]

So, after some tedious searching, I’ve narrowed down the cause to my game’s crashing issue to it’s overuse of RAM. I’ve noticed that as soon as my KSP starts using more than 3.4 GB of RAM it crashes. How do people run so many mods without the profuse crashing issue?

 

(I understand that KSP has a ram usage limit)

KSP does not have a RAM usage limit.

What you've probably seen is references to a RAM limit of 32 bit processes, which is about 4 GB.  So if you're running a 32 bit version of KSP, you could be hitting that limit and crashing out.

If you have a 64 bit system, you could still be using the 32 bit version.  If you have a 32 bit system... there's not much you can do without getting a new computer.
