Excel 2007 VBA Array Size Limit

Question

Numerous sources I have found have suggested that the size of arrays for VBA code depends upon the amount of memory in the machine. This however hasn\'t been the case for me

Answer 1

Having run some tests it looks like there is a limit of about 500MB for 32-bit VBA and about 4GB for 64-bit VBA (Excel 2010-64).
I don't know if these VBA limits decrease if you are using a lot of workbook/pivot memory within the same Excel instance.
