Windows 7: Why doesn't Windows 7 see 8GB ram?

Why doesn't Windows 7 see 8GB ram?

I have a DFI 790FX-M2RS board with 8GB OCZ ram on it. I have updated the Bios to the current and Windows 7 still sees only 4GB ram with only 3GB usable. Can anyone help as to what to change? I went to Windows 7 so that I could utilize my 8GB ram.

Thanks,

there is a setting in some mobo that says use max mem. It should be unchecked if you have it, same for max cpu, and legacy floppy support. dont know if your mobo has it but its worth a boot

hi imullinex, and welcome to the forum.

erm, sorry for the maybe silly question, but are you using 64bit or 32bit windows?

32bit operating systems will not be able to see or use all your ram.

Mickey Just heard from the OP and you are of course right. It is 32 bit. He can run 64 ( i looked at his cpu), but went back to 32 because he was having problems.

thanks for the assist
