Query: one worked, other one didn't

I bought 2 of these ram sticks for compatible old motherboards. One of them worked perfectly and I am currently using it without a glitch. The other one did not respond from the start, looks like it was delivered faulty (Testing it on a fourth cpu to see if it responds... although not likely). I would suggest if you are buying more than one stick, evaluate the possibility of investing that money in building a new motherboard system.
