Problem with RAM

I have the following hardware:
motherboard Abit AB9 Pro
4 x 1Gb DDR2 PC-6400, 800MHz KINGMAX RAM
(two RAM modules are of model: KLDD48F-A8KB5, and two: KLDD48F-A8KI5)
Intel Core2 Duo E6600 @2.40GHz CPU

Motherboard correctly recognize all 4Gb of RAM (Info at the boot), but when
I open basic information about my computer in Vista Ultimate (32 bit) it
shows that I have 3070Mb of RAM.

Does anyone know where disappear 1 Gb of RAM in Vista? :-)

32 bit Vista, like 32-bit XP, does not show the entire 4gb of RAM due to the
way address space is mapped. You must use a 64-bit version of Windows if
you need 4gb or more of memory.

I suppose that the only way to solve this "problem" is to buy 64 bit Vista
because it is not possible to upgrade.

Thank you for your help.

Hi.
I have the same kind of problem, except that my system shows 3.25 GB of the
4096 MB installed.
I guess we have to go to 64 bits.

Unless you are using programs that are 64bit, and you need to access MORE
than 4gb, you do not need Vista 64bit, and would probably find it way more
restrictive than the apparent loss of some memory, which is used by the
system anyway, even though you do not have direct access to it.

can anyone explain when i upgrade to 3gb from 2gb of RAM, the system just
slows down and takes ages to boot up, i really doubt it got something to do
with bad ram or mobo

You can doubt it all you like but this is usually down to the motherboard.
