If I've installed Windows 7 64 bit on a PC that had a 4GB of RAM limit when I first got it, and it came with Vista 32bit, does the PC now have a limit of 8GB of RAM? Or is it still 4GB or RAM?

For me, ur question isn't clear. If u have Vista 32 bits, ur usable RAM will be 3.25GB, independent of the RAM that support the mobo. When u install the x64 bit OS (Win 7 x64 in ur case), the amount of that usable change to the amount of RAM supported by the mobo. In that case, the x64 bit OS don't have a limit of 4GB of RAM. m 0 l srosenbloom May 12, 2010 1:58:45 PM How can I find out how much RAM my motherboard supports? Scott m 0 l Can't find your answer ?
