Question about KSP Memory Limit

[bulletrhli]

Now for a long time I have never had over 4GB of memory, but I recently upgraded to a 64 bit Windows 7 and added 8Gb of RAM because I am building a gaming computer. Everyone has said that KSP was limited to 3GB of memory (theoretically the limit for a 32 bit system after deducting system used memory) but I have maxed that according to my task manager and nothing has happened. Anyone know the reason for this?

32 bit processes on Win 64 can actually use the full 4 gig of address space but some is still reserved for some things. You should be able to take KSP up to about 3.4 gig before you start getting out-of-memory crashes...

Well I am using an AMD Athlon II 640 Quad Core which is a 64 bit CPU just food for though. I havent yet reached the 3.4Gb limit but I will have to try to push that.

Also, running 8GB will still help, not by letting KSP use more, but by letting other programs/the OS use the rest.

I think your GPU memory can factor into the 4GB limit too. But I don't know for sure.
