Windows 7: Only 2GB ram usable after installing ATI Radeon 5850

07 Nov 2010   #11

Windows 10 Pro x64, Arch Linux

As tw33k said you must enable Memory Remap feature in your BIOS

Windows 7 Pro 32 bit

tw33k and yowanvista - thanks very much for all your input, it is greatly appreciated.

I'll go and have a hunt around in the bios, haven't found anything on google as yet (specific to mine).

Been there, done that


you could check this out :

Maximum usable memory for 32-bit Win 7

As stated there, your problem is the 32-bit OS, that has a restriction on how much memory it can map.

I made a clean install of 64-bit Windows 7 to my comp, and now all the RAM is in proper use. Before doing the clean install, it's useful to have an external drive where you can transfer most of your files with "Easy Transfer". And you'll need all the installation files for your applications, because they'll get sweeped in the process.
