Re: Win 7 64Bit install. 4GB RAM showing as (3.50GB usable)
To have all 4GB available to use you would have to find and enable a
Memory Remap setting in the BIOS. But I think the Dimension 9100 was
only sold with XP, a 32-bit OS, so the setting probably does not exist
even though the hardware is capable of using all 4GB.
