I understand the 32 bit Vista limit in addressing only 4Gb of memory space but I have a very specific question:

I have 3Gb installed on a Vista 32 bit system with a 512Mb video card, MSI X-58 board, Intel i7, 920 CPU. System Information currently shows: Installed Memory: 3.00Gb Available Physical Memory: 1.73 Gb

My understanding is that the 512Mb video card occupies memory addresses between 4.0Gb and 3.5Gb and so does not subtract from the 3.0Gb of physical memory (correct my understanding if wrong)

My Question: If I install another 1Gb of RAM, will my Available Memory increase to 2.73Gb?

Thanks, Bob423
