I have windows 7 professional and got 4gb memory installed but it only seeing 3gb in windows is this normall?

Also is there a 32bit and a 64bit version and would getting a 64bit version see the memory?
 
To address all 4GB you'll need the x64 version. Do you have a retail or OEM copy of Windows 7?
 
With 64bit Professional you can use unto 196gb ram, with 32bit you would use 4gb, but this encounter any other ram or memory within the system like graphics cards.
 
Even the first athlons did. No reason to use 32 bit these days unless you are using very outdated software that can't be made to work in 64bit.
 
I have a oem version so I need upgrade to a 64bit to get the 4gb to pick up as all it pick up at moment is 3gb when there is 4gb installed
 
Yeah i had 32bit Win 7 for about an hour and quickly upgraded! Seems quite pointless nowdays with most programs working on both and RAM being so cheap

Just remember, you need to do a clean install for 64 bit windows 7 Pro.
 
I have the same but have both editions 32 & 64 bit.

Does the 32bit still use the full 4gb even though on my system it only show it as 2gb ?

If its says its using 2gb, then thats all it will use. May want to check MSCONFIG -> Boot -> Advanced Boot and make sure maximum memory option ISNT ticked too.
 
The 32-bit versions of operating systems (not only Windows) will use some of the 4GB address space to address I/O devices (called memory-mapped I/O), so some of the physical memory will never be used. That's why you see only 3GB available.

Use the 64-bit version, and that problem goes away.

As far as I know, Windows licence keys can be used interchangeably on 32-bit and 64-but versions of the same O/S. So if you can get hold of the physical media EXACTLY the same version os the one you are using, your existing key should work, and you won't need to pay the "Microsoft Tax" again.
 
Can I just install the new windows 7 on top what already installed will any software I alrwady have installed be ok or best do a clean install of everything?
 
You will have to do a clean install if you are going to 64bit, always the best way anyway becuase your computer will be like new :D Use WIndows easy transfer for all the files and documents you want to keep

Clean install is needed. The software installed will not work if you do an over the top install without formatting the drive. Backup your personal data, format the drive, install windows (x64), re-install your apps from your master discs.

I have done the deed and now have 64bit 7 on my pc on the C: drive after moving all my saved photos media etc on to the spare hard drive...

I done a fresh format as suggested and everything is working quicker as expected..

I went into mscong as suggested and it is set at maximum memory is set at 0

One thing I did notice when I looked into the tools option was that it said

C:\Windows\system32\winver.exe

What's that all about I formated and put 64 bit on why is there a reference to 32bit ?

Still showing 2GB installed and also in the bios as well even though I have changed them into different rails and booted up one at a time just incase one is faulty....they are defo 2GB ram just don't seem to be showing up together.. ??

Weird!
 
System32 will always be there, its part of windows, no matter what. What motherboard do you have? May want to run memtest, just to make sure none are faulty, one stick at a time.
