Probably no the best MB to use for OC, but that's what you have.
The E8400 should have no major problem reaching 3.6GHz with the right setup. I think in your case, the limiting factor might be you ram speed. As I am not sure what multiplier options you have for your memory.
For your reference, I have the same CPU @3.6Ghz using 1.248 Volts.
I would recommend you Google around for similar setups and read your MB manual.
