I will be running some memory-intensive softwares (FEM software) on my new gaming rig using i7-2600k cpu with 16gb ram installed on gigabyte ga-z68x-ud7-b3 board. I understand from intel specification that the maximum memory size for this cpu is 32 gb. If the FEM software requires more than 32gb (say. 50gb) ram to run an analysis, will it then run into problem on the 64bit windows 7 platform. Windows 7 x64 can support up to 192gb ram. In this case, will the 64bit OS allocate about 34gb harddisk space as virtual memory for the FEM software to run the analysis, or will it be limited to 32 gb limit imposed by the cpu. I'm a bit confused about this. Can anyone enlighten me on this? Do I need a xeon type processor if I need very high memory allocation (including harddisk space as virtual ram) for cases > 32 gb usage ?
