Either something is wrong with your configuration or an i3 with DDR3 isn't that impressive memory wise. This is what I get with my Q6600 @ 3.56 with 2 cores disabled and DDR2 @ 952.
What could be "wrong"? I saw this program in another thread used, so I d/l it to see what I got. He got nearly 3x as much as me, but was also running 12GB of ram..
