    Im running 4 gigs of ram on Windows XP 32 bit, the bios recognizes all 4 gigs but windows XP only is recognizing 2.5 gigs. My desktop uses xp and 4 gigs, and xp is recognizing 3.25 gig.

    Does anyone know why this is? ( i know all about how XP cant recognize 4 gig because of the 32 bit, 2^32 is less than 4 gig of memory addreses, but why is my lappy only recognizing 2.5 gig and my desktop 3.25...)

    It's a chipset limitation, not a software limitation; even though XP can recognize more, your laptop's chipset will only let it use 2.5.

    The chipset however will let X64 users see 4 gigs in OS?

    Correct. You'll be able to utilize all four gigs with a 64-bit OS.

    Im having a hard time wrapping my head around why the Chipset would let the OS only see 2.5 gigs in a 32 bit OS but 4 Gigs in a 64 bit OS.

    I know how the OS can only map a certain ammount of addresses in 32 bit OS, but once again were coming back to the: my desktop lets a 32 bit OS see 3.25 gig and laptop only 2.5Gig.....

    I understand this is sort of a dead thread, but did the 3GB switch help you Mausimo?

    I did a bunch of research and also contacted my reseller. The reason why the 2.5 gig is only showing up is because of the chipset limitation as stated above. However i was told a new bios will be coming out that will allow the 3.0-3.25 gig to be utililized on the 32 bit OS's.
