The amount of memory LabVIEW can utilize depends on the bitness of LabVIEW and operating system used.
LabVIEW (32-bit)
- On a 64-bit Windows operating system, LabVIEW can access up to 4 GB of virtual memory without modification.
- On a 32-bit Windows operating system, LabVIEW can access up to 2 GB of virtual memory by default. This can be extended to 3 GB by changing Windows' Boot Configuration Data store.
LabVIEW (64-bit)
- LabVIEW can use up to 16 TB of virtual memory when using LabVIEW 2009 (64-bit) or later on Windows Vista (64-bit) or later.
Besides the Information profile buffer allocations window can be modified as shown in the attached.
moreover,
Operating systems use virtual memory to allow applications to access more memory than what is available in physical RAM. The OS partitions physical RAM into blocks called pages. When an application or process assigns an address to a block of memory, the address does not refer to a direct location in physical RAM, but instead refers to memory in a page. The OS can swap these pages between physical RAM and the hard disk.
If an application or process needs to access a certain block or page of memory that is not in physical RAM, the OS can move a page of physical RAM that an application or process is not using to the hard disk and replace it with the required page. The OS keeps track of the pages in memory and translates virtual addresses to pages into real addresses in physical RAM when an application or process needs to access that memory.
