I am wondering if you took the time to read what I wrote 10 minutes ago:
Unfortunately, it is people like you that bring most confusion to forum discussions, as you feel confident replying on basis of what you saw by scrolling trough in couple of seconds, and someone like you will just pick up where you left.
Your argument case still doesn't hold up for overclocking. Yes it says 143% frequency increase, ok thats fine and dandy BUT it doesn't say 143% vcore increase. You may be able to set the frequency and if you have a lucky chip, it will be able to run at those speeds. Asrock is smart enough to not have Vcore because if you start raising vcore you will burn the mosfets. Who knows, it might of had vcore in earlier revisions but they might have removed it due to burn out issues. Still, if you can adjust the frequency, its still not false advertising. I was able to take my 3570k to 4.2ghz without a voltage increase at all.
If you want to do some overclocking with more options, buy a better motherboard, period. Asrock doesn't make bad motherboards.
