i have vista 32 bit ultimate version.
i have 4 gigs of corsair xms2 pc2-6400 installed and i see 4 gigs being read by bois but in windows, it only shows 3 gigs. so i went into bios and enabled memory remap and then booted up again. now it shows only 2 gigs of ram in windows.
*** man?
It's because you are running the 32-bit version. There is a technical, computational limitation (not exactly sure how, someone else will probably elaborate) of 32-bit operating systems, that only allow them to use about 3 gigs of RAM, including Video RAM... that is why the Max varies depending on what Video card you have.
If you purchased a retail copy of Vista, it includes both 32-bit and 64-bit versions. If you purchased an OEM copy, I've heard you can call Microsoft and they'll ship you a 64-bit copy for a minimal fee (around $10?) if you provide them with your Vista Serial number (make sure you're registered, too).
But until then, it's impossible to use all 4 gigs on a 32-bit operating system.
i was running 64 bit version and it would show all 4 gigs after i enable the map remapping. so u might be right about that. now i am back on vista 32 cuz the 64 bit version' wasn't installing all the updates(some of them were important and not just recommended)

p.s. cpu-z is reading all 4 gigs.
Yeah, CPU-z will read all the memory, but the problem is it can't actually be used by a 32-bit operating system. I was actually considering getting 4GB or RAM, but I decided on installing 32-bit Vista, so I just went with 2GB for the meantime - at least until drivers improve for 64-bit. I might pick up another 2GB in the future if I decide to switch up, though.

2^32 = 4,29,4,967,296 bits
Therefore, a OS has only 4GB of unique memory addresses. However, Windows reserves some for devices leaving 3.5GB left (not 3GB). However, video memory requires address and takes away additional total memory. You can enable PAE which adds another translation table to increase memory addresses.

your not going to get all 4 gigs,32bit is limited to 3.5 gigs do to the lake of bits that it can handel at one time with woul be (32) 64bit has a way higher amount and can support 100 of 1000 of gigs of ram.

(2^64) = 1.84467441e19 bits (or 2 exabytes)
Not quite true either. 64-bit OS have imposed limitations which is usually either 128GB or 16GB (depending on OS).

The 4Gb with a 32bit system will be even worse with your Creative Labs sound card. You will lose hardware acceleration with more than 2Gb.

If you have XP32 and 3 or 4 Gb enabled , open dxdiag and run the sound test.
If I remember correctly, the general consensus was that Creatives drivers were attempting to use the same memory addresses as the additional ram.
I can do a screenie of the hardware buffering not supported prompt if you like.
