Asus X470-F Gaming upgraded to 5800X, but system fails to start.
I'm trying to upgrade my CPU from 1700X to 5800X. As soon as I power on, the MOBO shows a DRAM diagnostic LED right away. A single POST beep appears just before the splash screen. I freeze at the BIOS splash and see both the DRAM LED and Boot LED lit up. I updated my BIOS for the MOBO on Asus's site. I followed all the steps from the forum thread, removed the M.2 drives, tried booting only from HDD, and cleared CMOS multiple times. Even leaving the computer unplugged overnight with the battery removed didn't help. The curious part is that when I switch back to the 1700X, it boots normally. I'm starting to wonder if something went wrong with my setup. I've never had a brand new CPU fail like this before, especially after years of building rigs. It feels like I might have bought a faulty unit and won't be able to fix it without going through the hassle again. Maybe someone can help me figure out what's going on.
Revisit the 1700 release and verify if BIOS was successfully upgraded by checking board details using tools like CPUZ. Try extracting the chip, inspecting the contents, and confirming the update wasn’t applied. Remember, some updates might not fully write due to how they were run. I faced a similar problem once where an Asus board changed via BIOS tool but didn’t fully flash the new BIOS—had to use Windows updater for completion. It was frustrating, but I managed to resolve it eventually by examining the extracted files. I’m hoping this isn’t the case and that my setup is compatible with a future 5800X upgrade.
I hope you manage to sort it out and share your solution! It led me into exploring how to edit BIOS files, which turned out to be a challenging path. I think I used a program named ami bios editor or something like that to inspect the BIOS file and looked at the CPUs listed in it compared to the one on my board. The process involved checking data over several months filled with frustration.
In my situation it turned out the same, so I started with basic steps. Try downloading the BIOS from the motherboard and open the file using a program, then check it against the Asus website to confirm it matches. Alternatively, you could use the method you applied before or try an earlier version that works with the 5800X instead of the newest release.
Ensure the BIOS updates properly to enforce default settings such as RAM speed and timing parameters. Adjust RAM to a lower configuration (e.g., 2133 MHz) and configure PCIe speeds manually at 3.0. Repeat these steps until defaults are consistently applied.
