My gigabyte radeon hd 7970 oc is at 1.256 voltage, how can i set it at 1.170 voltage?

question 2: is 1.256 voltage meant for water cooling? (Mine has air cooler, is that okay?)

Any help would be nice...

Can I somehow reset my gigabyte radeon hd 7970 oc ghz?
Is voltage 1.256 okay?
What is the default voltage for that video card?
Is 1.256 voltage meant for water cooling or 3 windforce coolers is okay?
whats the best selling price? :D

You can download MSI afterburner. Then go to options and unlock voltage control. Then a slider will be usable on your main MSI Afterburner Interface, AS LONG AS you card voltage is not locked through gpu bios. 1.25 volt do not require water cooling as long as your temps stay below 80 C. You card may also throttle when exceeding a certain temperature, that is set again in the bios of your card. You can identify when your card throttles, of you see your core speed fluctuating. I would keep the card below 1.23 volt max

Did you change the option in Afterburner to unlock voltage control? If you did and still you cannot change voltages, then the card is locked through bios. The only option left is to use a custom bios, or edit the bios by yourself which of course requires a level of proficiency. Also flashing bios to cards is dangerous and may damage permanently your card and also any warranty is cancelled.
Is this voltage the stock one? If so, 97 C is too hot to tolerate.
Changing the voltage should not be your first move though. Have you cleaned the heatsnik and card? You can apply new thermal paste on the chip. That will most probably do the trick

Okay i will try it
But if my gpu has 1.256 and 3 coolers (WF) does it mean someone has modified it or can it come out like this from factory also?
Honestly i donno if it is stock on, is it? All i know its gigabyte 7970 ghz oc version

The voltage seems normal for a factory OC card especially power by amd. I don;t think it is modified however you can check some things by yourself. Find the original bios of your exact card, make and model, on the internet and ispect your bios internals. You will find there clock speeds, boost clocks, temperature throttle limits etc. If you find differences to your card i.e, different boost clock, memory clock, throttle temps etc then you can claim the bios is modified.
Leave it for the time and clean the card. Keep it well below 80 C if you can. If it is an older card, then new thermal paste will be needed for sure

Do you mean for AMD radeon hd 7970 factory oc / gigabyte radeon 7970 factory oc or both?

Better this than damage the card. Don't know what "screws are made in China" is supposed to mean, but inexperianced persons should not touch things that are not up to. Good luck

yup you're right. He won it on auction and i sold it to him. Now he says like i sold damaged card to him... so now he must take it to expert to get it checked.
with "screws are made in china" thats how he explained the reason he cant change the thermalpaste and dust from inside.

If his system has a bad airflow, this can tell much for higher temps. Gpu coolers are useless in a closed box. Just inform him. The rest of what i recommend is just a typical work around when temps go too high.

Yeah, it shouldn't go that high i guess. Did it work well on your system? Now that the weather is getting hot, this can justify higher temps. I still believe the card will be fine when cleaned and when new paste is applied.
Are you sure the voltage is locked on that card? Just in case he overvolted the card and he is trying to scum you. I 'll try tomorrow to find the stock voltage of your card.
P.S: FurMark is designed to use the heat as a variable of testing. It is meant to overheat the graphics cards as to find the throttle point

Update: I had a closer look at the afterburner settings. There is no overvoltage but something is wrong with the temperature limit. The slider looks dead and there is not temperature reading above the slider. There may be a problem with Afterburner overiding radeon wattman settings. I guess the coolers of the gpu are not being used as they are supposed to. Ask if the fans are spinning, and/or fluctuate when using the card.

Ok, it seems then that temp limit and voltage control are locked in bios. Nothing we can do. Cleaning the card is the suggested procedure. Was the card performing cooler when you were using it? Unless there is a serious problem with amd drivers, i cannot think anything else apart from the card being dusty and needing new paste.

When i had it, my max temp reached 83C. But yeah, its probably dusty and need new thermal paste. Also he was testing other same gpu card and it worked nicely. (link: https://www.youtube.com/watch?v=nq2RmQtSncM). But he didnt want to clean it and wanted to resend it to me, but i declined because i know i sent working card. Also offered him to return it to me, i do cleaning and new thermalpaste but no. So now he must take it to an expert, then we'll see who is to blame here. If Im mistaken i must pay the expert testing if not then he must.
