My 5700 red devil is stable with 5700XT bios. Perhaps thermal problems if the frequency jumps and card is unstable? You can always limit the frequency and/or power usage back to original or at least stable values using wattman.
Still I am a bit sad that I can't do anymore modifications to the bios after the first flash.
The strangest thing is that with a voltage of 1.1000 and a specially set frequency of 1500 - it still resets it to 1300 ...
Gotta open command prompt with administrator privileges/rights, use the unlock command along with force command, if you want to know all commands in amdvbflash.exe
Punch in amdvbflash.exe /? Or amdvbflash.exe -?
You can use wattman or afterburner too
Sounds to me like your eeprom is not erasing/defective for some reason.
I doubt they'll fix this though because bios flashing is not covered by warranty.
If so, your options at this point are ugly, limited, and may not even work.
Oh, if you only knew what I didn’t do. And undervolting and powerlimit boost. I used to overclock the 7950 and I know how it looks, but there is no fixed frequency. Now 1700, then 1950 and so on.
When upgrading to AMD12.19.3, the situation worsened and immediately the frequencies worked at 1800-1600 - no higher.
I'm afraid some kind of protection is really installed there. Bios used 1 in 1 as the theme creator.
Will it help if I buy a programmer, will it be a brick. The problem is that I bought the store CompUniv.
Of course, I also have a spare bios, but I’m very afraid to flash it, or try it all the same.
If you don’t believe me, I can show it through - team viewer...
He does not even allow to flash his own BIOS again. (XT)
