Enable Loadline Calibration as this helps with vDroop.
Set DDR2 REF Voltage to nominal (the middle setting).
Disable both Spread Spectrums because they cause instability at high frequencies.
You're not overclocking your CPU? the voltage is set unnecassarily high.
Sorry, should have pointed out I am trying to overclock my cpu higher, its an E6550 2.33ghz FSB1333 and it is currently at 400x7 = 2.8ghz.

The problem is, everytime I try to push the fsb higher the system won't boot and I think its down to the memory but i'm not sure where i'm going wrong.

I have seen on other forums at least 3.2ghz and a review made it up to 3.85ghz with the E6550 using different motherboards!
