Did any one read any of the reviews? Just curious. Yes there are a few chips hitting above 4.5Ghz and even 5Ghz, but the ones above 5Ghz are few and far inbetween. The guys getting those scores either got lucky with their chip or they went through a bunch to find a chip that would do it. These chips as has been reported in virtually every review out there have a "WALL" that you hit and you could put 2v through them and they will still not move past that wall. If they could, then dropping some LN2 on them and pushing the voltages would have gotten better than the 5.6Ghz that sits on top of the HWBOT scores right now. It's not like benchers haven't been trying to push these chips.
OP, go read this before you blow up your chip:
And here is what Hardwarecanucks stated in their review:
However, even if you buy a K-series chips, your success is not guaranteed. Each chip is unique, and each will have a different highest stable CPU multiplier. Some chips will have a functional 53X multiplier, some will not be able to go above 44X, for example. This is now obviously the #1 factor in whether your chip will be able to overclock well or not. Max Multiplier + Max BCLK = Max Clock Speed, totally idiot proof. Only a lack of voltage or cooling can prevent you from reaching that Max Clock Speed once you've determined the multiplier and BCLK limits. No tweaking or fancy skills necessary, at all. And no amount of voltage or cooling can help you gain additional headroom once the max has been found.
Based on a third-party's extensive testing of 100 retail D2 stepping processors, this is how Sandy Bridge is shaping up on the overclocking front:
Approximately 50% of CPUs can go up to 4.4~4.5 GHz
Approximately 40% of CPUs can go up to 4.6~4.7 GHz
Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)
As you can see, unlocked K-series Sandy Bridge chips overclock quite well. Not amazingly well, but quite well. They perhaps won't match many people's expectations, but few things are able to satisfy the hype in the computer realm. Hardcore overclockers will obviously have disdain for this iteration of Sandy Bridge, as they should, and they would be well advised to wait for the LGA2011 Sandy Bridge platform, which has been rumored to be more overclocking friendly.
