Basically, my computer has 6gb RAM, BIOS says so, my system information says so, CPU-Z says so. But for so reason Task manager only sees 2gb and that is what its using which is crippling me as I try and use 3d studio max.
I must add I'm running vista 64 bit. I hear memory get alocated to other hardware like GPU but 4gb?!
IF you installed the memory after installing vista, use cpuid to see how much ram is on your system. Vista and 7 don't always update new hardware. I'm sure others know how to update vista, and may chime in.
Vista is detecting the memory correctly. Available physical memory is the leftover max the board will run with. You have 6 gb installed, but you can use 2 gb more. You must be using 2 2gb and 2 1gb sticks, instead of the maximum (4) 2 gb sticks.
