This sounds pretty good, I just hope that they use flux-less solder rather than thermal paste between the chip and the IHS. At least on the K series of CPU's, after all they are aimed at overclockers.
Easier? How does more complexity equate to being easier? One could assert that you can have greater success through the manipulation of two variables than just a single variable but I am not seeing how this equates to an easier overclock...
Overclocking is simple enough as it is for Sandy/Ivy Bridge; what we want is better overclocking ability/potential.
If Intel had surprise success with improving timing margins to provide 1GHz higher average clock yield, they would simply launch a product lineup with most of that 1GHz factored in.
With multipliers locked across all lower-end models, Intel ensures that overclocking headroom remains relatively modest compared to what it used to be when most low/mid-range chips were still overclockable by at least 33% by simply changing FSB clock ratio.
"even though in the past users could overclock non '-K' series CPUs through altering the base clock without touching the multiplier."
I think the author may not be aware that non '-K' CPUs have partial unlock, so to OC a non-k, most enthusiasts would actually touch the multiplier first to add +4 before touching the clock.
Maybe I'm missing something, but how is this any better than just using the core multiplier?
It should greatly benefit non-K chips. The biggest winners from this should be the Pentium's & i3's which have no available "K" versions or Turbo Boost and have been virtually frozen at under 3.5GHz for 2 generations now with typically only +/- 5% BCLK to play with... Many people have been crying out for the return of super-overclockable budget dual-cores ever since the i3-530 Clarkdale (with 2.93GHz -> 4.3GHz overclocks) got "upgraded" to the i3-2100 (with 3.1 -> 3.3GHz overclocks) when Sandy Bridge locked "core" and "uncore" frequencies together...
In fact, overlocking on BCLK-locked Sandy & Ivy Bridge i3's has been so poor that 1st-gen "i" series BCLK unlocked 2010-era i3-530's are still faster in many benchmarks than the 2 years newer Ivy-Bridge equivalents. Examples:-
If this BCLK-unlock is "across the board" and not just limited to premium "K" chips, then it's great news for Haswell i3 owners, as a stock 3.4GHz i3 could be OC'd to 4.25GHz (with 1.25x / 125MHz BCLK) and not just limited to 3.5-3.6GHz as current Ivy & Sandy i3's.
