8GB installed (3.25 useable)

Hi all. Just installed 8GB ddr3 on my windows 7 machine. Checked in the control panel my system info, and it says I only have 3.25 useable. How can I alter this. Would my games use the full 8GB or do I have to change something in windows to free up my 8GB mem for gaming purposes.

*thetrickser I have tried to install over my 32 bit with my 64 bit disc, but *it wont allow me to do it.

You can't do it. The 2 discs are provided so that you can choose to install which version you want but you can't install over the top, it has to be a fresh install and as butemanhas pointed out, if you want to dual boot (although I can't think of why anyone would want to do that) you would require a 2nd licence.

I think you have provided the same link as I had in a previous post.

bremner. Is seemingly is coming back with relevant information on how to upgrade from 32 to 64 Bit without a fresh install.
