I have a P4 Northwood socket 478 2.8 fsb 200. I am trying to figure out some basic information about my voltage settings. I went to intel to find out my core voltage, as well as, read about other users. I came up with 1.525 but iam a little confused, because I have the program cpuz and it reads 2.6 voltage settings. What is my voltage line? And what is my suggested core max before overclocking? Thanks for any help! I new to all this. I am presenting looking to build a new rig, as well as, max out the one I have. I have a Sony Vaio PCV-RS420 - P4 Northwood 478 2.8 w/ Hyperthreading. Thank You!
