    Intel Core i7-4770K “Haswell” Overclocked to 7.01GHz - Report.

    Intel Haswell Demonstrates Overclocking Wonders Ahead of Release

    It is not a secret that it is going to get easier to overclock future K-versions of Intel Core i5 and Core i7 "Haswell" microprocessors because of variable DMICLK/BCLK [base clock] coarse ratios. Therefore, it is not surprising that professional overclockers have already started to test the new chips in a bid to set-up clock-speed records. While no actual records have been set yet, Core i “Haswell” chips have already hit 7GHz core frequency.

    Haswell Hits 7.012GHz Ahead of Launch
    Journalists from Ocaholic web-site have discovered a record in the CPU-Z database that an unnamed overclocker had managed to boost the speed of an Intel Core i7-4770K microprocessor from 3.50GHz to whopping 7012.8MHz (91.07MHz BCLK*77). The overclocker used Asus Maximus VI Extreme Edition mainboard based on Intel Z87 core-logic. While the utility claims that the core voltage of the chip was upped to unprecedented 2.56V, it should rather be considered as a software bug, than a miracle since Core i-series 3000-family “Ivy Bridge” chips fail at 2.0V.

    Results submitted to CPU-Z database cannot be cheated, but they also cannot be tracked down to find out a particular person. It is unknown what kind of cooling system did the anonymous overclocker use to overclock the Haswell chip by two times over its default frequency. One thing is clear, though: Intel Haswell seems to be very capable of reaching high clock-speeds, even early in its lifecycle.

    Better Overclocking
    Intel Core "Haswell" desktop platform is going to offer unconventional flexibility when it comes to boosting performance. Core i "Haswell" chips will feature more "knobs" for relevant frequency and voltage domains of the chip [compared to today’s products] as well as higher core ratios for those, who want to set-up clock-speed records using extreme cooling methods like liquid nitrogen. The main improvement of Haswell platform over
