How much did you pay for this broken board? you have to be careful attempting a repair or you could end up damaging a CPU with it.
yes im aware of damaging the cpu,but i dont think one missing pin would damage it,maybe if the pins were bent and shorting but dont think that would happen,board cost £45
trying to get hold of someone selling new sealed 2600k for £155 but seemslike a pi$$ in the wind to me
