Memory Recognition

Will Vista Home Premium recognize more than 2GB of ram?

The local computer guys says no which seems strange to me.

Yes, it will recognize up to 3.2 gb or thereabouts of RAM. Not all
computers will take more than 2gb of RAM, however.

Yes. 32-bit Vista, regardless of which edition, can recognize
somewhere between 3 and 4GB. All 32-bit versions of Windows (XP as
well as Vista), even though they have a 4GB address space, can only
use *around* 3.1GB of RAM. That's because some of that space is used
by hardware and not available to the operating system and
applications. The amount you can use varies, depending on what
hardware you have installed, but is usually around 3.1GB.

You don't say where you found your local computer guy, but it sounds
like you might want to look for someone better informed.

SP1 release notes say that Vista32 will now report up to a full 4GB.

Vista will see a little over 3gb if 4gb is installed, but no individual
32bit application will use more than 2gb..

There are 32 bit applications that can use more than 2 GB if
the /3GB switch is enabled. FSX is one of them. With
add-ons FSX is bumping up against the 2GB barrier. Even
if the switch is not used, having more than 2GB is useful
because applications will not have to share that 2GB with
the OS, which will then have its own space above the 2GB
boundary.

You're welcome.

All the 32-bit Vista systems, along with other 32-bit systems. have a
32-bit or 4GB address space. Some of that address space must be used
to access your video board, BIOS, etc. Therefore a 32-bit system will
not actually be able to use an entire 4GB of RAM. You'll probably be
able to see 3GB or so. See http://members.cox.net/slatteryt/RAM.html

That's not quite true as Linux has an expanded memory option which enables
up to 64gb although the 4gb limit per task remains.
