Review on Intel Core i7-4790K CPU (8M Cache, up to 4.40 GHz) - BX80646I74790K by Micha ukasiewicz

i7-4790K. It heats up VERY. Under the lid - some kind of nonsense. Having the experience of re-purchasing (the first one accidentally fell on the parquet - and . that's it), I can say: an instance is different from an instance, like heaven and earth. With a considerable cost of the product, the owners of two different copies may end up with completely dissimilar prospects. For example, the second I (forcedly) bought two cores are always a couple of degrees Celsius hotter than the other two cores. While the "deceased" had absolutely equally heated and very evenly cooled cores. Stepping sold in 2022 4790K - C0. You will not find stones of this model with a more advanced revision (C1) in the 2022. Conclusions suggest themselves. Overclocking. Index "K", in this case, is nothing more than a completely shameless marketing ploy - with the aim of significantly increasing the cost of the most ordinary Haswell, only a little more successful in manufacturing than its other counterparts. But the "beautiful index" will not help - because the stone heats up very strongly and very quickly; and to cool it well, with such a small area of ​​the contacting surface of the crystal, is, in fact, technically impossible. At the same time, under the cover of the top model of the series there is polymer slag, with very modest, let's say, heat-conducting performance. In my case, in a newly purchased sample that was scalped, the thermal interface looked as if it had already dried up from long and merciless use. BOX-Retail version, the Seller seems to be adequate; known throughout the country. There are no traces of use before sale on the processor. I did scalping, filled in Coollaboratory Liquid Pro. The result is minus 5-6 ° С. But this does not help with sensible overclocking. In the sense: there is almost no sense. My final processor behaves stably when increasing the frequency to 4.6GHz, i. E. only 100 (!) MHz. With a further increase, the stability of operation cannot be guaranteed, no matter how cool. Tip: build the machine on a different socket, if possible.
