wot about vista or vista lite can they handle more than 3GB ?
Your serial wouldnt work because its a different OS. The main difference is the fact that you need 64bit drivers and these are sometimes hard to get, they can also handle more RAM by default. The E6600 does support 64bit.
32 bit vista handles RAM exactly as any other 32bit OS, the limit exists in all 32 bit versions of Windows. There is a 4 GB address space available to a 32 bit OS. Some of this address space is needed to memory map peripherals. The motherboard does this before Windows loads and this determines how much RAM Windows reports. Some motherboards have settings in the BIOS that can change this, most don't. The fix is to run a 64 bit OS. Even then some motherboards will still have this limitation.
