So, if I understand you correctly, the same system running Windows XP would have more RAM available for programs if the 4GB are installed than if it only had 3GB installed. Correct? Just out of curiosity: how do I find out how much of my present 2G of installed memory is used up by my hardware? On my laptop, the video is integrated and I believe uses part of the memory. Is that a factor? Thank you very much. Jeff

To utilize more memory, install a 64-bit version of your OS". Jeff

There is only a 64 bit version of XP Pro and it is OEM only. If your motherboard supports 4 GB of ram, XP(32 bit) will provide RAM for all addresses that are NOT used up by addressing your installed hardware. It is that simple.

I ordered the 4G of memory. I was going to anyway, just wanted to understand better. Jeff |
