This was announced on Wednesday in the official Twitter account of ASRock, which manufactures motherboards.
In response to a question from one of the users of @ASRockInfo, whether Z270 Supercarrier motherboards will support Coffee Lake processors, the answer was that future processors are not compatible with the 200 series motherboards.
Subsequently, ASRock removed its response . There is a version that it is made under the pressure of Intel.
PCWorld magazine editorial staff contacted representatives of ASRock, but received no response. Intel refused to comment on the message on the Twitter-account ASRock, noting that it does not comment on future products.
PCWorld believes that one of the possible reasons for this decision of Intel may be the so-called "market segmentation"
PCWorld believes that, with the new processor, . That is, the company wants to get paid more money.
Another possible reason – the company wants to make sure that the whole system is guaranteed to be balanced and avoid possible problems with technical support. There is a possibility that officially Coffee Lake will work only on the Z370, but unofficially they can be inserted into the old Z270 motherboards with the previous chipsets. But this is only hope, because in fact, this possibility may not be. Although the Coffee Lake chips are based on the same 14nm process technology and will probably use the same chipset, it could be the first 6-core processors on the new platform, and the Z270 motherboards were not designed for such power consumption.
PCWorld believes that this is because PC users can refuse to purchase Z270 cards, and perhaps the current gesture of ASRock is a kind of attempt to influence Intel so that it changes its mind.
