X470 Gaming K4 BIOS update issue

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello, I need some guidance on updating my X470 Gaming K4 motherboard to the latest BIOS version. My current version is 4.90, and if I update directly to 10.50, the PC will not boot afterwards and I have to manually roll it back to 4.90. Is there a required bridge BIOS version I should flash first? My CPU is a Ryzen 5700X.

	That is odd, there isn't a bridge between 4.90 and 10.50 so it should just work. When you update and power on, how long did you wait? Sometimes it can take a while for RAM training with some updates. I generally leave the system powered on for 10 mins, if it still isn't POSTing then there is some kind of issue. When updating I follow these steps: Enter BIOS and reset to defaults then reboot into OS and shut down Enter BIOS and update to latest version Shut down system and use clear CMOS jumper Power on and allow time for RAM training If that still isn't working open a support ticket with ASRock here: http://tw.asrock.com/events/tsd.asp The latest BIOS should just work with your setup.
