    Hi everyone,

    I've been trying to determine which BIOS files are compatible with my PowerColor HD 7970 model is AX797-3GBD5-2DHV3. I have hit the CCC memory clock ceiling and I am looking for a BIOS with a higher memory clock limit but with the same reference clocks and voltages. For my reference model it was easy to find the BIOS with 2000MHz limits but stock clocks and all low-power states available, but the Powercolor card is not reference and that BIOS is not compatible.

    I've looked at the TPU database but I haven't yet found one that will work for me. This is complicated by the TPU database not listing the CCC limits. I looked through the PowerColor section of the database and found two, both of which are unacceptable. I have tried the PowerColor "Vortex" BIOS, which has higher clock limits but it has a much higher core voltage and 1100MHz core clock. This caused artifacts on my card, and while I could downclock the card to not artifact, even the low-power states on that BIOS still use the 1.2V core that guzzles power at idle. The other is the Powercolor "GHz Edition" BIOS that has no low-power states at all.

    Does anyone know if there are any other BIOS available for this card, even if from another manufacturer, that will have higher CCC limits but will otherwise maintain the standard clocks and voltages?

    Thanks in advance!

    that's a great suggestion. i will check if i can add that.

    if you go to dev.techpowerup.com, the bios database there has a compatible bios button that might help you search

    Thanks for pointing out the "Compatible BIOS" feature. I didn't know it existed. Now I found that there are about 20 BIOS that are compatible with the card, but I have no clue what the CCC limits for them are without testing each one. Is there an easy way to investigate this without flashing and testing them all individually?

    Listing the CCC limits in the BIOS database would be really helpful. Listing the voltages for the power states would also be helpful, but I could see it being deprecated relatively quickly with the increasing number of power states on newer cards (e.g. HD 7790), so I so not know if it would be worth the effort to include.

    CCC Limits have been added to BIOS DB.

    Voltages are dependent on each individual card, based on leakage (ASIC Quality in GPU-Z)
    purecain and cadaveca say thanks.

    I thought that was only for NVidia cards; I thought AMD still used the same voltage for all cards regardless of ASIC quality. When did this change? I must have missed it.

    HD 6000 I think, HD 7000 for sure
