The announcement in AMD 2017 that AM4 slots use 2020, but recently AMD said 300 or 400-series motherboards were incompatible with Zen3 processors, sparking protests. AMD changed my mind tonight, Zen3 new benefits announced。
AMD listened carefully to the feedback from fans over the past week, according to an official blog post today.After repeatedly weighing the feedback from customers and facing severe technical challenges, we finally decided to overcome all difficulties and build upgrade channels for the existing b450 and x470 mainboards, so that they can support the new generation of Reebok processors with zen3 architecture!
Zen3's downward support for 400 series chipsets is not a simple sentence. From AMD's statement, there are many technical limitations. In fact, there are many preconditions for this upgrade. Amd explained in the final part of the official statement, mainly including the following 7 items:
1. AMD will work with partners to support zen3 processors in the beta BIOS of some b450 and x470 motherboards.
2. After these optional BIOS updates, some of the Reebok desktop processor support will be disabled to free up ROM space.
3. It is expected that the optional beta BIOS, which will be released later this year, will provide a one-way upgrade for AMD zen3 processor and will not support brushing back the old BIOS.
4. to reduce the confusion,AMD will only provide BIOS download to those 400 series motherboard users who have purchased zen3 processor and have been verified, so as to ensure that they have available processors after refreshing BIOS, and minimize the risk that users cannot boot after brushing BIOS.
5.BIOS update time and availability are different and may not be consistent with Zen3 release time.
6. This will be the last upgrade of the 400 series motherboard, and the processor after zen3 needs a new motherboard.
7.AMD will always recommend customers to select 500 series motherboard for the latest CPU performance and functionality.
After reading these points, users of b450 and x470 motherboards should weigh whether to upgrade the BIOS in the future, The BIOS. of the vendor can be considered if there is a need to Zen3 the processo
If it's for new BIOS functions, users of 400 series motherboards should save money.
