I know AM5 and the X670E chipset are new and therefore all over the place, but i updated to bios version 0611 and am still noticing a few issues so i thought i would take my life in my hands and try one of the later Beta versions of BIOS, yet when i try to update to either 0614 or 0703 just as it is about to start, it reboots.
After rebooting it just about gets to the login screen for Windows 10, then it reboots again and then complains that windows didn't load correctly, then i end up having to reboot for the third time which is really quite irritating given these boards have a longer boot time, even after the initial period of memory training has completed.
I was doing this via Ez Flash 3 within the bios menu but have yet to try doing it via bios flashback, which i am hesitant to do.
Is this a common issue or is there a specific process for loading the beta versions?
I Got a X670E Hero Board that came with a 401 bios and experienced the same issue as what you described , i got a bit scared when i saw the Mainbord shutdown when i clicked oke to flash it .. i didn't try it for a 2nd time but i tried the Bios Flashback .. that worked flawless and i am running on bios 611 atm.. (Bios FLashback is really easy if you got it on a USB drive (Fat32) "with the right bios name" then put it into the Biosflashback usb port turn off the pc and hold down the Biosflashback button for 3 Seconds then release it and wait . the button will flash blue and let it be wait until it stops emitting light then it is done.. start pc and it might give you a Bios is updating massage en reboots then it is done.
the only issue that i have now is that with Bios 401 i didn't got the onboard Igpu and only the Rx 6900XT as it should.. but now with Bios 611 i got a extra Display adapter that is the AMD RDNA2 onboard Igpu and i cannot find any setting the bios that can Disable the IGPU .. do you know how to disable that ? or is it a bios bug ?
