    Thank you for your info, Art!

    But it is a kind of bad luck for my interest. You say your Vista reports 4GB installed. It is an ambiguity because there is a well known fact that Win32 can't use more than 3.2 GB. :confused:

    But! Maybe your Vista can see that odd 0.8 GB exactly due to integrated video "help"? I mean Vista shows us hybrid value of memory amount: amount of RAM used directly by Windows + amount of RAM reported by integrated video.

    That's what I'd guess. Vista just says that the system has 4G installed, it doesn't actually say that it's using all of the stuff by itself. As a by-the-by CPUID also registers the full 4GB, but doesn't say anything about how that's divided up or actually used, although the Catalyst driver tells me it's using 1470MB.

    It's only an 'ambiguity' because you persist in thinking that video chips soldered to the motherboard and under full control of windows are the same thing as PCI-e cards that have their own self-contained vram.

    Vista started showing the full 4GB as of SP1, but has not changed the way it uses memory.

    Whatever. To be blunt I'm not that fussed on the exact use of the RAM, as long as it functions properly. No, you'd probably not get the full benefit of 4GB but hey, the difference in price between an extra 1GB stick and an extra 2GB stick is pretty small.

    Yes, like I said:
