Processors Skylake-X family, which should come to market in the near future, will offer a very decent overclocking potential, which can reveal even without resorting to extreme cooling methods. With such a statement was made by the German overclocker Roman der8auer Hartung , known to the general public on the design and production of Delid-Die-Mate devices for removing heat distribution covers a different CPU. In confirmation of what has been said it makes acceleration scalped 10-core Core i9-7900X to the frequency of 5.0 GHz using a closed LSS serial production Corsair c 280 mm radiator.
The overclocked processor is not overheating and worked perfectly stable under the full load of the utility Prime95 26.6, which actively uses AVX-instructions.
The performed demonstration runs counter to earlier rumors that Skylake-X overclocking will be similar to its predecessors, processors Broadwell-E, and without the use of extreme means of cooling ceilings typical for them will be the frequency of the order of 4.2-4.4 GHz. As shown by the experiment conducted by, Skylake-X should be dispersed much better, but it will have to pay special attention to the heat sink: the heat dissipation from the new CPU overclocking increases very sharply. For example, in the experiment der8auer temperature operating at 5 gigahertz frequency at a voltage of 1.32 The CPU Core i9-7900X reached 88 degrees even when using LSS Corsair Hydro Series H115i. The maximum allowable temperature for this CPU, where the throttling is activated, is 94 degrees.
Better than the Broadwell-E, overclocking potential Skylake-X did not come out of nowhere. The fact that for the production of Skylake-X Intel has decided to apply the modified workflow 14+ nm, the same as used in the production of Kaby Lake. Semiconductor crystals grown on such advanced technology used in the 12% higher level of control currents and have an enlarged pitch gate transistors (presumably from 70 to 84 nm), which ultimately reduces leakage currents and allows to achieve stable operation at a higher frequency. For example, issued by such process technology Core i7-7700K four core processors can operate at frequencies of about 4.8-5.0 GHz and even higher.
The results of their experiments overclocking Core i9-7900X der8auer described as follows: ” From my point of view Skylake-X – an impressive processor. In the new generation we have desyatiyadernik, which is much cheaper Broadwell-E, but it operates at much higher frequencies. Even without scalping I was able to overclock the Core i9-7900X to 4.8 GHz using the factory LSS Corsair. This means that if you take a self-assembling “dropsy”, the thermal interface on the OEM can be squeezed and 4.9 GHz, provided that will get a good processor. And when I changed in my copy of Intel’s Core i9-7900X thermal grease on the liquid metal, I have succeeded to overclock to 5.0 GHz with a maintenance-free life-support systems . ”
It is worth noting that their der8auer experiments carried out with pre-selected by the processor. That is why the average instances of Skylake-X is so impressive overclocking show, most likely, will not. However, 4.7-4.8 GHz, for der8auer opinion, after scalping can be squeezed on any chip of new generation, making a platform LGA2066 processors Skylake-X an attractive choice for high-performance enthusiasts.
In other words, by overclocking potential processor family Skylake-X will be more like Kaby Lake, than Broadwell-E. The frequency of 5.0 GHz will not be something unattainable for Core i9-7900X even at home, and to receive it in the 24/7 need three things: a good instance of the processor, scalping and cooling performance. But even without the CPU selection and extra work for the replacement of the thermal interface by the processor lid on Skylake-X, you can expect a good overclocking potential, which can be an important advantage of the new platform in the background of previous and competing solutions.
More information about the processors Skylake-X and LGA2066 platform will be known tomorrow night at Intel event, which will take place in the framework of PC Gaming Show. Complete reviews Skylake-X processors, expected to be published in the computer press in a week.
