RAM problem on Vista 64 bit

My OS is Vista 64 bit Ultimate and I have 4GB RAM but Vista still shows it as 3.25 GB. I thought that a 64 bit OS would resolve this issue but nothing has changed. Any suggestions?

What chipset are you using?

Sorry for the late reply guys. I have A MSI Platinum P965 motherboard. Oh and I am absolutely sure that I have a 64 bit Vista as it says so in my Computer properties.

You running DDR2 800? Because according to MSI's website that boards limits to only 4GB when using DDR2 800, weird. That would be my guess.opamando

I have an Intel C2D E6600. I have not heard of hardware taking up memory before. I googled my problem and I have to enable memory hole remapping in my BIOS but I cant seem to find this feature in my BIOS. Maybe a BIOS update as I said before?

which processor do you have? mayb you have a 32 bit processorjoshuahaveron

Lol, he would have to have an ancient CPU for that to be the case.

I think we're talking pre pentium 4

Its done. I just had to update my BIOS. Apparently my BIOS was dated and I had not updated it since i bought my PC. Vista is showing the full 4 GB RAM.:Dant_1411

That's good man.

I'm confused about this 32/64 bit issue, as after installing 4gb in my computer, expecting to see it showing as 3.5/3gb in system properties, it does actually show 4gb. So my question is, is my computer using all 4gb, or just showing it in system properties as to let me know what is actually installed. I have a Sony Vaio FZ21z.starlinct

Computer won't be using all 4GB unless it is an application that uses lots of memory. It show 4GB whether you have 4 GB available to the system or not.

If you bring up the Task Manager and click performance there is the Physical memory there which you can use in MB. Most applications rarely use this. Most games will use 2GB max.
