Thanks Thanks for the fast reply! I also read the thread about getting The Sims 3 in 64 bits, and I don't know where I should post this (link below), or if it is even relevant to anyone, but I read it a little while ago and it was a really great explanation in fairly non-technical terms about how memory works in modern systems. http://blogs.msdn.com/b/ericlippert...memory-does-not-refer-to-physical-memory.aspx What I gathered from reading it is that having a 64 bit binary allows the process to much more easily deal with having a large amount of address space (it literally can load more address space at the same time). It also explains why not everyone encounters this error in The Sims 3. The trick is to make sure there is a large amount of contiguous space available. I mention this here because it can apply to other games and programs that get this error, it is just that The Sims 3 is just very notorious for its memory problems. Spoiler: The Sims 3 specific info I personally have 16 GB of RAM and have not had any memory problems with TS3. I use only one mod: velocitygrass's add any lot size script, and I have all of the expansions except the newest one and a lot of store content.
