I did today just receiver two sticks of 256mb PC100 rams and they seem to not work. I wonder if I need one sided type ram to fix this. But the problem is where can I get a 256mb PC100 that is one sided rams? If there anyone maybe in here that can sell them to me? Or does anyone know a website where I can get two sticks of 256mb PC100 one sided rams? Someone said that my system doesn't like two sided rams and I think they were right.
