Ok, you will need to go into your motherboard BIOS; when you first turn on your computer, click F2 or DEL on keyboard (usually). You need to update the motherboard BIOS to latest version, and you need to set the RAM speed to 800Mhz.

Usually what happens when you put 2 different RAM sticks is that the motherboard will set them on the standard lowest speed, which I think for DDR2 is 667Mhz.

So you need to update the BIOS in order to set them to the same speed of 800MMhz and to the same voltage (1.8v).
