Interesting article by Borandi!
In the past, overclocking a processor for ‘free’ performance involved taking a cheap model and pushing it past the top end model. In the land of Intel, overclocking by any significant margin has been limited to the more expensive processors – with Sandy Bridge it was common so see a 3.4GHz processor overclocked to 4.6GHz with very little ‘effort’ for those with overclocking experience.
However, Ivy Bridge is now released and behaves differently with regard to Sandy Bridge, in a couple of perhaps alarming ways that we think you should know about. We always want to be thorough here at AnandTech with our analysis, so this article is all about our results from Ivy Bridge overclocking – especially in terms of what to look out for. Ivy Bridge overclocking is a different beast to Sandy Bridge, so we want to make sure there are several clear correlations implanted in a users mind when it comes to a stable Ivy Bridge overclock. For our other readers, we also have some notes regarding some undervolting results on Ivy Bridge.
