Overclocking processors has always been a game of finding the right adjustment of clocks to reach the highest frequencies possible without disrupting the work of other components that on the motherboard are tightly depend to reference clocks. During the IDF, there has been many talks about the fourth generation core processor “Haswell” and Intel once again displayed efforts to make overclocking more “seamless, easy and accessible” to entry level enthusiasts.
What Haswell can that Ivy can’t
One of the limitations that the “Haswell” processors intents to correct from it’s predecessor “Ivy Bridge”, is the capability to make overclocking adjustments flexible in realtime from you desktop. Indeed, the problem with the 3rd generation Core processors is that we have the obligation to re-edit parameters from the BIOS as Windows the BLCK is blocked. (missing the good old times of setFSB and clockGen)
The solution that Intel promise to have in its processors is a 4th Generation BCLK variables with values from 1.0, 1.25 and 1.66.This should, in comparison to the actual 3rd generation BLCK present in the LGA2011 socket CPUs, allow a greater level of overclock by simply moving multiplier and bus clocks without the inconvenience of overclocking all other components (SATA, PCIe).
In addition to this, Intel revealed that there will be a portable version of the tool “Extreme Tuning Utility” to be called “Pocket XTU”. The interesting thing about this version is that we can overclock from another PC or smart-phone remotely without having to use a proprietary hardware/software addition as we have it today on ROG boards by example. However, a minor inconvenience which may exist is that of course the benchmark results may be altered by changes made on the CPU frequency.
Is it really new?
Well for those of us that have known in the history of overclocking the period of setFSB and clockGen it might appear as the re-introduction of a feature that more less similarly existed once before. Of course nobody is going to complain about the capability to adjust frequencies on the fly from the desktop, nevertheless, we might have to see once these processors are launched how all this actually works and performs.
