I tried to fix it but got no where. The same thing happened with an AST RAM card, where it also had random issues that I couldn't sold. So with my friend David, we created a new IBM PC diagnostic ROM that runs a very comprehensive RAM test to help fix these two broken parts, but they just work now!
