How much faster is xp 64 than 32? Is vista 64 ready for prime time yet? Will 64 bit make video editing faster? I have some questions on this and if anyone can answer I would greatly appreciate it. Thanks.
Wrong, a certain amount of system ram is reserved for video memory swapping. That's why in 32-bit Windows the amount of usable memory will vary depending on the amount of onboard memory your video card has. Some people have 2.75GB of main memory show up, some have up to 3.2GB.rik said:Graphics card ram has nothing whatsoever to do with mobo ram unless you have built-in graphics on said mobo.
In the absence of the /PAE switch, the Windows memory manager is limited to a 4 GB physical address space. Most of that address space is filled with RAM, but not all of it. Memory-mapped devices (such as your video card) will use some of that physical address space, as will the BIOS ROMs. After all the non-memory devices have had their say, there will be less than 4GB of address space available for RAM below the 4GB physical address boundary.
where it makes no difference in his example anyway.So it also depends on how much RAM you plan on installing, and I believe that your graphics RAM counts too, for example if you have a graphics card with 512MB of RAM, and you have 3GB of RAM and XP 32-bit installed, you will only see and be able to use 3GB of RAM.
...says Didou who has 4 GB of RAM in XP MCE - according your profile. Disappointed?Didou said:3GB is fine, 4GB is a waste.
