64-bit system finds only 3328 MB RAM

Generally its around 3.5GB of useable out of 4GB of RAM. A 64 bit OS uses a tad bit more memory than a 32 bit OS and may account for the extra RAM usage.

So, this allocation happens at BIOS level? As I said, BIOS claims I have usable 3328 MB.

I added 1GB of memory. BIOS shows the 5120 MB correctly, and at the same time, still shows only 3328 MB as usable.

E8200 is 64-bit as per Intel's website.

This seems incredibly similar to this other post:

In short, it's possible to be a limitation on the motherboard rather than Windows itself. Even though Windows 64 bits hasn't the ridiculous 4GB arbitrary limitation of the x86 version, it's still bound to the hardware limits and maybe other hardware is using that address space for its own purpose.

Did you try the BIOS reset?

Pulled the plug. Took out the CMOS battery. Held the power button down for 20 seconds. Didn't to the jumper reset. Nothing changed.

I don't think it's either. According to the mobo manual, it recognizes up to 4GB DDR3 or up to 8GB DDR2 memory, so, it shouldn't be a hardware limitation, especially given that I use DDR2.

I have currently 5GB RAM installed and BIOS still shows 3328MB usable. With 4GB RAM it showed 3328MB usable, too, and as such, I'm ruling out the GPU use that other guy had trouble with. The GPU address should take away a fixed amount, not set a cap.

*bump*

it depends on manufacturers specs of RAM
