I recently installed 4 gig or ram into my 32bit vista box. I realize that I wont be able to use the entire 4 gig until I go to 64bit vista, but 2 gig wasn't enough and I figured I could use as much of the 4 gig as vista will allow until I upgrade to 64 bit.
When I installed the 4 gig of ram, all of my PCI cards, A second graphics card, a second NIC, and a firewire card, stop working. Looking in device manager, the error was "This device cannot find enough free resources that it can use".
I read that PCI cards need some of the addressable memory space to use for memory mapping? Is the problem I use it all up with my ram? If so, Can I reserve some memory for these devices?
My computer is a Dell Precision 390. It has the Intel 975X Express chipset and an Intel Core 2 6600 @2.40 GHz processor.
Update: Removing my second video card allowed the other two PCI cards to start working. I'm not sure why.
