Overclocking on the ASRock 4Core1333-Viiv was not as bad as i thought it would be for a board with no voltage or multiplier adjustments. We were able to reach a top overclock of 340fsb. This is a nice little boost for those that will be using this board. Free extra performance is always a nice thing, though we could not help but think of what could have been when you think of other 965 boards that are overclocking monsters. But for a board that retails for over $100, I think we could use a wee bit more control over things in the BIOS.
