ram problem

[desperado73]

I have a problem my cpu E7400 is working fine also my videocard gainward 7800gs+ but I recently bought two corsair 667mhz ddr2 sticks each 2gb.But my bios reads only one slot of 2gb and not the other one. but if I run CPU-Z it shows me both sticks with 2x2 : 4 gb ram

I would trust cpu-z for your memory quantity. Some versions of windows will also list 4 gb.
