You should install windows in 64 it's the best way to manage more than 4Gb

Its the only way to manage more than 4 GIG, any 32 bit operating system suffers from the 4GB ram issue. You should go with a 64 bit OS, ideally 2008 to solve your issue.

the other option is to install hyper-v in bare metal mode.
With one VM 2003 32bits and an other in 64bits.

you will need to install the version you want to keep if you go the trial route, x86 - x64 isnt possible without a clean install. Why not get the 2008 X64 trail and then get a code if suitable ?

You win't like the answer - but you cant have more than 4Gb RAM with Standard Edition 32bit.

with Server ENTERPRISE EDITION ONLY - you can use the /PAE switch to address more than 4Gb RAM.
Only ENTERPRISE editions of 32 bit windows server support the /PAE switch

64bit editions of Windows all support more than 4GB RAM natively

As stated, Enterprise Editions support more than 4 GB, but through the use of PAE so even though it "sees" more than 4 GB, there are still aspects that are limited that wouldn't be with a 64 bit system.  Problem with upgrading to Enterprise is the cost - Enterprise will run you about $3,000.  

As stated, you CANNOT upgrade from 32 bit to 64 bit - a clean install is the only way to change the "bit level".

OEM licenses are locked to the hardware they are first installed on.  So that license is either used on your server now and forever, or it is LOST and completely wasted.  This is the reason it's cheaper - you accepted that you would pay less because you agreed to the restriction of installing it on only one machine, EVER.

OEM licenses CANNOT be used in a VM, so virtualizing is not a solution here.

For the most flexibility and the best price, you to purchase a volume license of Windows Server 2008 R2.  Yes, this will cost more (2003 volume licenses are no longer sold - but keep reading). Volume Licenses permit downgrades to prior versions, so you have the right to install ANY version of Server Standard you want.  Volume Licenses also allow you to switch between bit levels (still require a clean install).  Volume Licenses are locked to the company they are sold to - so they are transferable to other hardware.  And finally, volume licenses CAN be installed in VMs.  And volume licenses don't cost that much more than an OEM license (unfortunately, your existing OEM license is wasted at this point because you cannot transfer it to another system).
