Lock the PCIe frequency at 100MHz, get it off of auto. Same with the ram. (you want 200MHz I think, might be 400MHz.) I'm not sure what options you have and DDR3 will change the math a bit. I'd start there and see if you can get a bit more.

Is this the original E6300 that was 1.83GHz? Keep in mind you already added an extra GHz so getting to 3GHz might not be possible.
