Hello.....I'm running Vista 64 bit, and I've read all of the information on memory restrictions when running the 32 bit version vs the 64 bit version. On my new machine I just built, I brought up the 'system information' feature, and I'm seeing the 4 gigs of ram I have installed. Out of that, it says that I have approx. 3 gigs of 'available physical memory'.
Someone else was telling me that on a 64 bit version, it should be showing the full 4 gigs available, and that it seemed like I was running 32 bit, which I'm not. I don't think this is correct since after you subtract the memory used to run the OS, it seems 3 gigs would be about right since Vista uses somewhere close to a gig when running. If I was running the 32 bit version with my hardware (graphics card has a gig of ram), it would be showing even less available system memory. I'm including a scenerio below that i think illustrates this. Can someone tell me if this is correct, or is something not right on my 64 bit system? Thanks very much.....
Vista 64 bit - 4 gigs of system ram plus 1 gig of video ram on the graphics card for 5 gigs total. So...the 4 gigs of system ram are available, minus ram needed for running OS = around 3 gigs available physical memory. Vista 32 bit - 4 gig limit including video ram. The gig of video ram accounts for 1 of the 4 gig max., which leaves approx. 3 gigs system ram available....minus ram needed for OS leaves around 2 gigs available physical memory. If this scenerio is correct, then all is normal with my Vista 64 bit system in what it's reporting. Does this make sense?
