Pavilion a1250n: cannot use 4 GB of memory on 64-bit operating system

I resurrected this PC to give to my grandson, so I added 2 GB more memory.

But when he starts, he sees only 3 GB.

The configuration of the BIOS shows all 4 sticks of 1 GB.

I ran the test memory Windows startup, and it shows all 4 GB and it extracted all OK.

But, the properties of PC watch 4GB installed, 2.75 GB usable.

I confirmed that Max Memory has been disabled in the MSCONFIG startup parameters.

Googling has provided advice to set up activate Memory Remap in BIOS - but there is no such setting, in fact, there are NO parameters associated with the memory in the BIOS.

I am running the latest version of the BIOS - there is no update.

I use an add-in video card GeForce and hoped there will be a setting in the BIOS to avoid system memory allocated to the integrated video chipset, but only focus on the video entry is to choose what video is the main, and I already defined on PCI - E.

I am at one loss as to what else to do...

Hello:

What you see is probably normal for a PC with an AMD chipset this old.

I know for a fact that on a desktop computer Intel, you must run with a chipset 965 or newer which takes in charge of 8 GB of memory or more, so that Windows to "see and use" 4 GB of physical memory.

These PC that can support 4 GB memory shows the same amount of memory usable net as a 32-bit operating system.

There is nothing you can do about it.

I guess the same goes for AMD platforms... you probably have a PC with a chipset that can take over 8 GB or more memory on order for Windows to "see and use" all of the 4 GB of physical memory.
