I've read in various places that one can overclock non-K Intel processors by 400MHz (4 bins) by upping the multiplier as long as you are using a B75 or Z77 motherboard. Has anybody tried this and/or confirm that this is indeed true? Is that only limited to i5 and i7 processors with turbo-core or is it true for i3s and Pentiums as well?
DPete27 wrote:Ok, new addition to the discussion: We've established that it is possible to increase the turbo multiplier on "locked" i5 and i7s by 4 on Z77/Z75/B75 mobos making for a 400MHz increase there (assuming you stick with the default 100MHz Bclk).
Now, there are Z77 boards that run all 4 cores at the max single-threaded turbo clock by default to pump their benchmark numbers. (Multicore Enhancement is the term) This could also apply to our overclocking efforts of non-K CPUs.
I believe it is also possible to lock your CPU on the max multiplier. The thing probably would never idle, but its possible to do. Now, put those two together... you've technically boosted the "base clock speed" by more than 400MHz? Have I made any inaccurate statements?

For non-K oc I say the i7-3820 is king. bclk oc, and +5 or 6 bins (multi goes up to 43 or 44, depending on your chip/mb).
It'll do just about any speed you can get a 2600k or 3770k to with a combination of multi and bclk, and you get the platform benefits of X79 and a huge 10MB cache.
I got an easy 4.5 GHz just by upping the multi to 43 and the bclk to 105.
