Theres is no way of telling, You have to up the speed in small amounts and then check stability and heat factors, if its stable try the next higher speed. Its not an exact science when it comes to over clocking, more like vodoo wink
And as I said befor no two processors are the same, Yours may handle 200mHz over normal or it may only take 50mHz. Its all about stability AND heat, you must keep the processor cool to over clock. You are asking it to run beyond its rated capacity and this means it will generate more heat. Too much heat :evil: and you fry it.
