Hello I have an AB350 pro4 motherboard with bios 3.0 running a 1500X. I just bought a 5600 to upgrade. I see that I have to follow the correct order to update the bios 3.4-5.4-7.0 My question is which should be the final bios that I install? I see there are a lot of beta BIOSes. Should I just install the most recent 10.41? I see that 8.02 is marked with either L or I. What does that mean? Is it a more stable long term solution? Any tips before I do this? Do I need to remove the CPU driver in device manager before I do it? Thanks |

When updating the BIOS for new CPU support it's usually best to update to the latest version. In the case of your board, that has been in production since Gen 1 Ryzen, the beta BIOS versions provide support for features the board was not officially supposed to support. Basically the beta versions are ASRock taking care of customers with older boards. Technically these older boards shouldn't be receiving updates anymore outside of critical security updates. I am not certain but IIRC the version that starts with an L addressed a security related update. All newer versions will include it's functionality, including the betas. They build their new versions, beta or otherwise on the latest stable version usually. As for the update itself: 1. Install the latest "all in one" driver from AMD (just a precaution) 2. Enter the BIOS and reset to factory defaults (or similar depending on wording) 3. Reboot into OS and shut down 4. Begin the update process from inside the BIOS using the "instant flash" method 5. Repeat from step 2 for the next version update until you have reached the latest version That should be it. Good luck  -------------
