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.

Are you using the 32bit version of W7, if so that's the answer.

Yes I am using the 32 bit version. Does that mean my games will only use the 3.25GB? If so that leads me onto my next question. When I bought my windows 7 product I recieved both the 32 bit disc and the 64 bit disc. Can I upgrade so to speak my 32 bit version to 64 bit or will I have to do a fresh install of the 64 bit version?

The 32 bit system can only use a maximum 4GB of the RAM so your games will only use the 3.25GB.

Yes you upgrade to 64 bit, but with any major operating system install or upgrade you should ALWAYS back up any irreplaceable data up before doing so.

Upgrade will cost you.

Not sure if you can run the 64 Bit version on an External drive without having to pay for it.

No you cannot upgrade from Windows 7 32 Bit to 64 Bit, it will need to be a custom install or fresh install . So if you go this route make sure you back up your files and remember that you will need to reinstall your programs.

See here: http://windows.microsoft.com/en-US/windows7/32-bit-and-64-bit-Windows-frequently-asked-questions

Fifth question down.

Sorry about the rubbish link, but the globe has disappeared.

Ignore last.

After a further search it seems you have to pay for a second licence if you want to dual boot the 32bit and 64 bit versions of W/7.

I see your link but I posted after a couple of IT colleagues stated they had quite successfully initially installed the 32bit W7 and later "upgraded" using their 64 bit disk.

I shall speak with them and ask what process they used.
