However, once the processor gets a kick in the proverbial nuts, it can turbo any or all cores towards that multiplier of 48 times that 100 MHz baseclock frequency, that's a 4800 MHz configuration. So these settings allow us to work at a baseline clock of roughly 3400 MHZ that actually still can throttle down to 1600MHz in idle, which helps us in power consumption.
And that is why Intel introduced the K series, since it offers you an unlocked multiplier which will allow you to go much, much higher. The new 100 MHz baseclock of Sandy Bridge processors is hard to tweak, if you are lucky you can get 115 MHz out of it with regular cooling, multiply that with your maximum multiplier and you'll notice that the default 2400/2500/2600 processor can only overclock a few hundred MHz at best. The new technology however has an embedded GPU / video processor merged into the very same processor die running over the same bus sharing the same 元 cache memory, things get increasingly complicated in matters of tweaking. So if you were able to apply a fictive 175 MHz on your base clock, you could multiply it with the limited 25 multiplier.
That base clock was capable of going so much higher, 150, 186 and when tweaked right, even over 200 MHz. With Nehalem/Clarkdale (last generation Core i3/i5/i7) pretty much you take your base clock of 133 MHz and apply say a default multiplier of 25, that would be your 3.33 GHz processor. Why K versions you ask? Well, the default Sandy Bridge processors will be much harder to overclock. We've mentioned at the start of this article already, if you are planning to do some overclocking with a Sandy Bridge based processor, you are so much better off with a K model processor.
