Windows 2003 Increase the amount of RAM

I have added 8 GB of ram to my windows 2003 server. I added the /PAE to the Boot.ini file and i can only see 4 GB of RAM. I found this article about the bcdedit command but I do not have it on my 2003 standard server and cannot find where to download it. any suggestions?

Check whether you have Windows 2003 32 or 64-bit.  The 32 bit has a limit of 4GB.

I'm afraid your server will not be able to see the extra 4GB in the 32 bit OS.  You will need the at least the 64 bit to see anything larger than 4GB.
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Standard edition cannot see more than4GB in your system properties but you can see the difference in speed even if does not show in the system properties.

If it is 2003enterprise you can see more than 4GB.
Have you enabled the memory remapping feature in your BIOS? Are all the ram sticks the same brand, model and size? How many? What server/motherboard is it?

Oh, I forgot to add to ensure this is x64 but it seems it's not.  In that case 4GB is the max.
The /PAE switch can be used to allow windows 2003 ENTERPRISE EDITION to access more than 4Gb of RAM.

It is not supported on Server 2003 Standard Edition which is limited to 4Gb (approx 3Gb usable)
"... my 2003 standard server ..."  ==>  As noted above, 2003 Standard Edition has a maximum memory limit of 4GB.     You should have checked this before adding RAM to your system.

The only way to use the added RAM is to upgrade to Enterprise edition or switch to a 64-bit version.
Note there isn't a direct "upgrade" path from standard to Enterprise, but it's well known that a "repair install" using the Enterprise disks will do exactly that.   However, if you don't already have a copy and have to buy it, I'd suggest you go with an x64 server.
