I was looking on GeekBench and noticed there are quite a few quad core iMac that are running faster than the 2.66GHz of the i5 and the 2.8GHz of the i7. I can't make sense if people really are trying to overclock or just somehow are making Geekbench think they have a faster CPU/are editing their scores somehow. How in the world could one overclock the iMac when cooling is a serious concern?
 
I would assume that is the turbo function....
The cpu overclocks itself

iMacs are not overclockable because there is no system BIOS to enter that allows the changing of the system clock speed. What you're seeing is either Turbo mode or a different quad core system they're comparing the 2.66Ghz and 2.8Ghz iMacs to.

Right, the turbo boost goes up to 3.46GHz for the i7 and i5 goes up to 3.2GHz. I was just curious where these numbers above 3.46GHz are coming from. But I think you answered that in that they are using a different quad core system, however under the description it says it is an iMac with the i7-860 with the stock Apple motherboard.

I wouldn't be surprised if they have a quad core Mac Pro thrown in the mix of benchmarks there.
 
Its been shown there are a couple of PC systems masquerading as an iMac in the geekbench system profile.
