How to increase overclocking of E5200

[Aabhas]

Please submit yours Overclocks for E5200.
I am asking this because I changed 3 motherboards I can't move past 2.75 GHz.
Now I have MSI P7N SLI PLATINUM max OC is 3.0 GHz at 1.37v 1190 fsb and I cant move past 1100 even at 8 multi and all voltages in red zone. So I am curious if is some FSB wall that E5200 have.

Thanks

You can try pumpig more volts.These E5200's improve its performance as the CPU volts increases, I have had 1.55 running through mine before. Also, these chips are FSB limited, I have a pretty rare clocker, most only hit 3.6GHZ.
