I have been trying to undervolt and underclock a HD 7970 from MSI but the miner loads the dags and the gpu frequency is stock inders 900 or 890MHz and the vddc is higher than stock(reading form GPUz)

I am using 15.11.1 beta, win10 64 bit, either on ethminer or genoil miner


So if i read this correct, your core clock doesn't go higher than 900? Or what do you mean?

Driver should be fine.

It's probably an afterburner setting you're missing.

Put your ab settings like this:



it has to do with windows 10 messing up the value i think, can you try on widnows 7?

Don't think it's Win10, never gave me issues. I had more issues with 7 though :p

In the MSI afterburner, in the general setting, you need to tick "Force constant voltage". So that you can change the voltage.

I wouldn't do that.

Force constant voltage <-- it will, like it states, force a constant voltage, so in other words, the higher your core clock goes, the more voltage your card will need to keep performing, when you select this, it will force the voltage you give it and will in most cases just fail because the card doesn't get enough power.


Did you flash this card before?

A bad rom could cause this yes.
the core/memory clock and voltage that MSI sets arent being used by the miner so it uses stock clocks and voltage

the thing is the frequency remains the same so It could a big with MSI AB

I don't always drink...
Had the same problem had to use VBE7 and atiflash the GPU ROM.

If you still can't do it or msi has the voltage settings locked after ticking force constant voltage you can mod the bios.  Most ati gpus have a bios switch on them and the gpu has a position for the read only only slot and a writable slot.  There a guide around here some place but it is pretty easy, just load a voltage modified bios on the writable slot and your good to go.  I had to do this with my sapphire dual X 7950, as the voltage settings were locked on it.

The good thing about the bio switch is if you load a bad bios, or a corrupted bios you can always go back to the stock system bios failsafe.
