It’s possible use 4GB/RAM with WinXP32? I have mounted this but Win recognize only 3GB. Someone can help me? 
Blitz, you need a 64 bit OS. Its the only solution to use more than 3 GB of RAM.
…or Win7Pro-32bit?
Ginancarlo il problema è trovare i driver di tutte le periferiche per XP 64 quindi o passi a win 7 o ti tieni il XP 32 ci ho già provato in passato e XP 64 non è ben supportato per i drivers
Thx for reply. I continue with XP32Pro, with 3GB/RAM and for other 4 years. Augh! 
4 more years with 3 GB?
I would change to Win7 64 bit, you will probably need more than 3 GB for Storm of War.
Rgr that Sir! I suppose for SoW go purchase a new machine. Thx.
