My friend is selling me a stick of OCZ 256mb pc3000, so I decided to test it out and it doesnt even reach 145 fsb, but for $30 I aint complaining. My problem is that I tried it out with my stick of 256mb pc2100 crucial and it worked allright. But I let my friend take it back home until he gets his corsair stick next week and his comp would not load windows. He claims the ram has been shorted but I dont see how that could have had happened. Is it really shorted?
