When I check my system information, it shows I have 4gb of RAM installed, as I’m aware I have…
However, when i pull up the task manager and check Performance, It’s only showing 3gb… I first noticed this when I installed a gadget for my sidebar that monitors RAM and CPU usage…
32 Bit Windows can only address 4GB of total RAM. And this sometimes can be sketch and act funny, but generally it amounts to 4GB - the VGA memory size. So if you have a 1GB video card, it would account for the missing 1GB the system profiler displays.
But regardless, this is normal operation. And 3GB of ram is adequate for most users.
Check in the bios for a memory compatibility settings… sometimes this has to be set in order to see over 3gb of ram. Even on vista x64, I had to set a flag to see all 8gb of ram instead of only 3gb.
