Okay guys here is the scenario - I have a P4 computer that was given to me a while ago. I got it up and running last night and started looking into it a little closer. Upon closer inspection i found out that the chip is a P4 1.6GHz chip with 256MB of RDRAM running (I have 2 dimm slots available). I dont know the make of the board so i cant give you that information. My questions are - 1) Can I take this chip and place it in another motherboard that makes use of DDR memory without any problems? 2) If the answer to the above question is no then will i be able to add more RDRAM to the system? Any and all feedback is welcome! Thanks!
