Run > MSCONFIG, open the Boot tab > click Advanced Options > make sure that Maximum Memory

but this wasn't helpful.

What about Bios Update?

Best Answer

Enter the BIOS and go to Advanced Chipset Features → North Bridge Configuration, then change the setting Memory Remap Feature to [Enabled].

From the manual:

Memory Remap Feature

This item is used to enable/disable memory remap feature. Its mainly for if you have a 64bit OS and 4GB of RAM. Basically it allows you to remap the overlapped PCI memory above the total physical memory.

If that alone doesn't help, download the latest BIOS update from here and follow the steps outlined in the tutorial How to flash BIOS?.
