I have the EVGA x58 board and have had no issue overclocking my chip. I did do a x19 multiplier, but doing 200 was pretty easy. One thing that I read in Anand's review was that the bios reports a higher voltage than what is actually being feed to the various parts, i.e. CPU, for example, if the bios says its 1.45v vcore, it may actually only be 1.35v vcore. I have not had a chance to measure using the voltage pads on the board, but I plan on doing this next week. Anyway, my point is that a lot of people are complaining about high voltage (1.41) to get 4Ghz and higher on this board and in reality it may not really be that much, just something to think about. Shamino is one of the gus that has worked on the bios, so I am pretty sure the bios, especially the latest one, are rock solid. Granted, the Classified will definetely bring some fixes and enhancements to it, I am just saying the current board is pretty sweet. Like I said, 4.2Ghz with HT and Turbo mode on was pretty easy once you understand the relationships between the settings.
