BIOS update for crosshair vi hero wi-fi ac not functioning
You're facing challenges updating your Crosshair VI Hero Wifi BIOS for a Ryzen 7 3800X. The post Q-code "8" and lack of access to the BIOS are common issues. It seems the Ez Flash button keeps toggling, suggesting a failed update. You've already tried various BIOS versions and formatted USB drives in Fat32 with different file names. The quarantine process is adding stress, especially since you're new to Ryzen and haven't found compatible parts. Consider reaching out to the manufacturer's support or checking for firmware updates directly on their website for more tailored assistance.
Make sure you properly rename the BIOS. You could place a BIOS between the current board and the newest version, possibly needing multiple iterations. I’d suggest starting with version 6808 since it’s the first intended for Ryzen 3000, then progress to the latest.
The BIOS file needs to be renamed simply to C6H.CAP. When you first download it, it appears as ROG-CROSSHAIR-VI-HERO-WIFI-AC-ASUS-####.CAP. You don’t require an extra .CAP at the end. Ensure the file is the sole item on the USB stick, not inside any folders. Just insert it directly into the unformatted drive using the designated BIOS Flashback port. Follow the steps precisely as listed in the motherboard manual. If issues persist, reach out to AMD for their Boot Kit support.
I also faced challenges with my Crosshair VI Hero (purchased soon after release). The problem was tied to BIOS settings as well. It seems a gradual BIOS upgrade might help—avoid updating to the newest version. This approach helped friends with older motherboards running the latest CPU and first-gen Ryzen boards.
It's worth noting that your setup seems to work smoothly without any problems. You're curious if others might try similar configurations, especially since your components are from reputable brands. Also, confirming the presence of a 'Ryzen 3000 series Ready' stick on the motherboard box would help verify compatibility.
The motherboard packaging includes a label confirming it's compatible with Ryzen 2000 Desktop. I reached out to an Asus support representative who confirmed the Ryzen 7 3800X works with it. The BIOS file for the 6808 is now isolated on my flash drive, and both a BIOS flash and a BIOS update attempt produced identical outcomes.
I changed the file name to "C6HWIFI". I didn’t include the ".CAP" at the end as usual. I also didn’t move the file out of the folder onto the USB drive. Here’s a summary of what I did: - Got BIOS version 6808 from Asus’ website
- Copied the file to a Fat32 USB stick
- Extracted files and renamed the BIOS file to "C6HWIFI"
- Placed the file in the root folder of the USB
- Removed all other files except "C6HWIFI"
- Inserted the USB into the BIOS header and held the button down.
I’m glad I finally have the BIOS ready for updating. It’s currently updating. Thanks for your assistance!
Great news! ASUS should revise their manual. It currently just mentions renaming it to C6H.CAP, even for the WiFi board version.
