Unless I am mistaken, you can't.  It is a limitation of a 32 bit architecture, it cannot address any more than that.

Good day,

One should use 64 bit architecture; in order to, use more than 4G of RAM. In other words, window 2008 x64.

Ah, I was not aware of that technology.  It appears 2008 does support this, although it depends if your Processor and the chipset also support it.  As to how you enable it, not sure.

You could upgrade the OS to Enterprise edition which will allow you to use upto 64GB. This is a supported upgrade path link however you will need to ensure your licensed correctly after the upgrade

You can follow the below link for more information regarding the upgrade process.

Moreover I would suggest instead of upgrade if the server is not very critical and if it possible to reconfigure application with less efforts, go with the fresh installation of windows server 2008 R2 or 2012 and meanwhile also check your application compatibility with both of the servers.

It is not a limit of 32bit OS's, you can add PAE to the boot options, and then some 32bit OS's will be able to support up to 64GB of RAM. But 2008 standard 32bit (as well as XP and all other 32bit desktop Windows OS's) do NOT belong to those OS's. You would need the Enterprise or Datacenter editions (as hinted to above) to get 64GB support on a 32bit OS.

As rindi said, you can't.  32 bit Server Standard operating systems as well as all 32 bit clients have been limited to 4 GB MAX (depending on hardware configuration - certain memory below 4GB is lost to hardware allocation).  YOU CANNOT CHANGE THIS.  Data Center and Enterprise Editions do have ways of potentially increasing that... but NOT standard and NOT client OSs.  Upgrade (replace) your server OS if you need more memory, assuming the hardware is 64 bit.

Why have you selected that comment as the only answer? I said the same thing earlier, and also the others basically told you you couldn't do it, although their answers were either not complete or not completely correct.
