<> >> I have a question: if I use a Stata MP 64 bits it would be possible to load this kind of dataset? Sorry I should have read your post more carefully. You already have a 64-bit system w/ 4G of RAM. Stata 11 MP will not make a difference in the amount of RAM you can allocate -- it changes the # of processors that can be used for computation. You need to install the 64-bit version of Stata 11 (this will be an option when installing from the disc). - Eric __ Eric A.

I tried to put more than 1.5 GB, but operational system refused to provide memory. I've read about this and it seems that windows does not allocate more than 2 GB on 32-bits applications. Also I've enabled virtual memory, which seems to be set on by defaut in Stata 11. Unfortunately, it didn't work. >> >> I have a question: if I use a Stata MP 64 bits it would be possible to load this kind of dataset? >> > > Yes.
