Insufficient Memory

@HippieWiccan13 Again The Sims 3 is a 32 bit application and CAN NOT address above 4Gb because of the very nature of being a 32 bit program regardless of how much memory your computer has. As other background programs execute in low memory (the Windows jump table starts at 0 memory location). Most compilers in use do not (can not?) generate a jump instruction beyond the 2Gb range. One of the Sims 3 patches (patch 1.17 in October 26 2010) enabled LAA (large address aware) by default and allows access to memory above 2Gb and use of this extra memory usually requires the use of assembly language routines (marcos?) that run outside the compilers. This is because of the micro code inside the cpu regarding the way the cpu accesses blocks of memory because of the address bus. Normally a 32 bit 4Gb computer would overlay the system roms (read only memory - bios, keyboard rom) over memory in the high end (just below the end of 4Gb) reducing the available memory by about .5Gb in a 4Gb system. The way the Windows operating system works is very complicated and for some odd reason the game tries to access memory the operating system has deemed protected. If the game is allowed to access these memory locations an invalid value will probably be returned and the game will execute an error routine and recover. If this is not allowed the game would probably crash because the Windows operating system will disallow access (this is a guess) - an operating system routine will run rather then a game error routine. This is a very, very simple explanation.

fyi
