Hello,

I have XP Pro SP2 running on a Dell Dimension XPS Gen4. I just recently
installed 4GB of PC4300 DDR2 RAM. System boots up and runs fine it seems.
Just noticed that only 3GB is reported in the tooltip in System window. In
System Information it reports 4096MB total memory though. Is this just a
display bug? Looks like quite a few people have this problem. Any solutions?
I have tried the /PAE command line option. Didn't change a thing.
