We recently bought a brand new HP Proliant DL380 G5 server with 8GB of memory. I Installed windows server 2008 standard edition x86 (32 bit). When I look at computer properties I can see that it shows 8GB of memory. Is it possible that this version of OS recognizes more than 4GB under certain circumstances?

Very interesting ... as you can see, Microsoft says the limit for the x32 bit version of Server 2008 Standard is 4GB:

... what does Task Manager show on the Performance tab for "Total" physical memory?   I'm just curious whether or not the Properties page shows total memory installed regardless of whether or not it can be used (like Vista does after SP1).

Windows Xp, Vista, and server (32 bit) all max out to less than 4 GBs of ram.
The Newer Versions of windows will show the entire ram you have, rather the show the amount of ram being used. In order to find out how much ram is being used Control +alt+delete
Hit task manager. Then on the performance tab look for Physical Memory in total will be the amount your pc is using for ram in Each MB 1024 = 1 GB. :) If you upgrade to the 64 bit version and install all your upgrades depending on your processor you'll get all 8 gigs.

Yes, as you probably already know, a 32-bit OS cannot address more than 4GB of RAM except in some cases using PAE: http://www.codinghorror.com/blog/archives/000811.html. The newer versions of the both server and desktop OS' do report the total RAM available - because it can be seen by the BIOS - but the actual structure of the applications means they cannot use the additional RAM.

Without upgrading to a 64-bit version of Server 2008, you cannot address more than 4GB of RAM.
