An AM4 interface serves the third-generation CPU. AMD has done it, and players can also enjoy it. If you are holding a 300 series or 400 series motherboard and want to experience the charm of the new generation of 7nm Ryzen, or want to abandon PCIe 4.0 in exchange for a more cost-effective motherboard, the following three steps will help you receive old user benefits.
AMD has promised to allow users of 400 series motherboards to support the third-generation Ryzen processors by upgrading the BIOS. You can find the corresponding model on the motherboard manufacturer’s official website to download the BIOS. Although the 300 series is not officially supported, the PCEVA editor inquired on Gigabyte's official website and found that many X370, B350 and even some A320 motherboards have received the F40 version of BIOS that can fully support the third-generation Ryzen.
However, there are still a few issues that need attention. The new BIOS refresh has some hardware and software limitations, and some AMD drivers have version requirements, and some require flashing a "bridge BIOS" before transitioning to the final new BIOS version. It is best to strictly follow the guidelines when refreshing to avoid accidents.
Due to the limitation of BIOS chip capacity, many motherboards will not be able to support Bristol Ridge processors after upgrading to the new BIOS (seventh generation APU, such as A12-9800, etc. ), and the BIOS version cannot be rolled back. If you are currently using a seventh-generation APU, be sure to confirm this is a one-way trip without turning back before flashing the BIOS.
If you buy a new 400 series motherboard to match Ryzen 3000, you need to contact the seller before purchasing to confirm whether the BIOS version of the motherboard supports the new generation Ryzen processor avoids the embarrassment of not lighting up after the platform is built.
AMD has teamed up with Microsoft to bring many targeted optimizations to the ZEN architecture processor. TOPOLOGY AWARENESS can try to make the threads of the program run in the same CCX, avoiding the extra delay caused by cross-CCX. CPPC2 is the third-generation Ryzen exclusive optimization: to increase the speed of the processor's transition between different power states, which is equivalent to the AMD version of SpeedShift.
These new features require Windows 10 version 1903 of the operating system to get support. Just relying on software If you can get such a big performance improvement, don’t hesitate to upgrade!
Install the new version of the driver:
The AMD chipset driver version number has been upgraded to 1.07.07.0725. If you are upgrading from the previous generation Ryzen, you should consider the chipset driver Update too. Because only the combination of the driver and the new BIOS can make CPPC2 fully functional, achieve a faster clock adjustment speed than pStats, and bring faster computer response.
One more thing. The editor analyzed the BIOS file of the Gigabyte B350 and found that the PCIe 4.0 option that AMD refused to support still exists in the official Gigabyte F40 BIOS. AMD's "no support" statement is to "relieve" motherboard manufacturers. There are a large number of old motherboards that came out before X570, and their routing cannot foresee the need for PCIe 4.0 in the design stage. PC on old motherboardCan Ie 4.0 work?
