Over-long life cycles and multi-generation architecture also pose challenges and problems for compatible upgrades. In particular, the SPI ROM storage space used to store BIOS information on motherboards is limited, resulting in some old motherboards unable to support new processors, or new motherboards having to remove support for some old processors, and some boards have deliberately released new versions of larger BIOS.
On the 400-series motherboards, for example, some of the railong 3000 processors that better support the Zen2 architecture have been able to remove support for the seventh generation APU Bristol Ridge of the excavator architecture, the first product to use AM4 interfaces.
It has been rumored that the next generation of zen3 processor needs to be equipped with the new x570 and b550 motherboards, while the earlier 300 and 400 series motherboards will not be supported.
Amd said in an official blog today that in the past week, it listened to the feedback from its fans carefully. After weighing the feedback from customers and the severe technical challenges they faced, amd finally decided to overcome all difficulties and establish an upgrade channel for the existing b450 and x470 mainboards, so that they can support the new generation of sharp dragon processors with zen3 architecture!
"Based on past experience, when dozens of different generations of processors are in and out of the support list, large-scale BIOS upgrades can be really difficult and confusing," amd said. With the growing number of fans of AMD sharp dragon, we have not forgotten our original intention. We need to broaden the road and provide more users with a safer upgrade experience. "
Of course, amd also confirms that the earliest x370, B350 and A320 mainboards will not be able to meet the new sharp dragon of zen3 architecture completely, but I believe that this can be understood by everyone. On the one hand, it is a technical challenge. On the other hand, using 2017 mainboard with 2020 processor, basically no one will do so.
