BIOS only sees 3 GB memory even though 4 GB is installed?
Hi all, I have a DFI Infinity NF4 SLI motherboard and currently have 4 GB of memory installed in it (4 x 1 GB sticks). In the BIOS, only 3 GB is shown, but when I boot up Windows Vista (32-bit), 4 GB is shown in the 'Welcome Center' window. I know that 32-bit operating systems can only use 3 GB, but is there something wrong with the BIOS preventing it from seeing all 4 GB of memory? Or is that just how it is? I do plan on installing Vista 64-bit very soon to utilize all 4 GB. Thanks!

Any 32 bit OS will have the same issue you describe. Nothing wrong with your BIOS. A quick and easy "sanity check". Burn a Fedora or Kubuntu LIVE 64 bit edition CD or DVD. Boot with it and verify that the OS "sees" 4G.

Are you sure your motherboard can support four? If so, then the simple answer would be just to go with what Vista sayes. I dont see why it matters what BIOS sayes if you know your OS will take full advantage of all of your RAM.
