You have to install 64bit OS to utilize 8GB of RAM, as 32bit operationg systems are limeted to 4GB RAM
Thanks Uzair. I appreciate your answer. I have to wait until almost all Softwares can run with the 64bit OS.
I am running my PC on DG45ID on Windows 7 64 RC with 8 gig memory and all drivers are available for 64 bit. I am thinking of upgrading it to 16 gig as this board does support it now as I run a lot of vmware virtual desktop on it.
