In order to archive high clock frequency it is necessary to increase either the multiplier or the bus frequency , or both simultaneously. The increase in the system bus frequency result in a synchronous frequency increase of other bus : As hard disk, for example, can be damaged, or high PCI frequency .
Associate reports that low-end models core i7 (Bloomfield) can not overclock very well since the clock generator, which in the default setting work at 133 MHz. is attached to some other parameters, and its increase can lead to the loss in the system stability.
Associate also reports that elder model core i7 with free multiplier is capable to overclock to more than 4 GHz with air cooling. In this case associate report that over 1.65 v can cause problems. In any event, bloomfield processors will get the built-in memory controller and new power system ; therefore some nuances in the overclock unavoidably will arise. Related Products :
