I dont know what to do. Help!

PS: I installed that Graphics Card despite there was no room, so i opened the lateral side, its open all times so the Graphics Card can enter.

Actually, with a 64-bit OS, the remapped PCI memory is reclaimed by the OS. So, he would have a full 4GB of memory available and "usable." The problem here is the memory arrangement. Memory on this processor and the chipset that it uses should always be installed in pairs. The memory arrangement you list has distinctly different modules in different slots. With differing memory modules, the chipset doesn't quite know how to address it, so it is sticking back in single channel mode, and still has to reserve some memory as unusable. Not only do you have memory that isn't usable, but your memory performance is taking a big hit.

I suggest you find a match for that 2GB module and just go with those. If you are anxious about not...

Correct me if I am wrong....

Windows always dedicates a certain amount of memory to itself. It reserves it exclusively, therefore it can not be utilized by other programs.

For example.
You have a car that has 400 horsepower.
It takes 50 horsepower to idle, run the heat, A/C, lights, etc.....
Therefore you have 350 horsepower that can be utilized to move/accelerate.

You still have all the 400, just it take some to keep the background stuff going.

Same with the memory, you have the 4 GB recognized, just some of it is used in the background and therefore less is available up front.

Long winded...sorry

All Intel chipsets starting with the 3 series properly handle flexible memory commits per channel. The cause is almost certainly the memory hole remapping being disabled in firmware. This affects all operating systems, including 64 bit ones.
