Title: How to under volt 7970 Post by: mpradeep on February 06, 2013, 02:04:19 PM I have OC Gigabyte 3 fan 2GB 7970 GFX card.
How do i under volt it. As of now i am running it at 1140MHz core clock and 685Mhz mem clock. How to reduce the core voltage to less than 1170mv?? I have tried in CG miner but it didnt work. I am a bit naive to this like some one to explain in detail on how to undervolt my card? Thanks Pradeep Title: Re: How to under volt 7970 Post by: KWH on February 06, 2013, 02:21:24 PM I have OC Gigabyte 3 fan 2GB 7970 GFX card. How do i under volt it.

I (and a lot of other people on here) use MSI AB. Set unofficcial overclocking = 2, force constant voltage, and undervolt. That's what I do with my Gigabyte 7970.

Just copy & paste this in your config: [ATIADLHAL] EnableUnofficialOverclocking = 1 UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it UnofficialOverclockingMode = 2 AccessibilityCheckingPeriod = 0 This has the same effect.....I think ;) Title: Re: How to under volt 7970 Post by: vdragon on February 07, 2013, 12:44:20 AM First of all, when did you buy the card? Older gigabytes had the ability to change voltage, newer don't. I have a few of both. Newer run on 1.170V, and could do 1150 smoothly, but you have the keep the room cool. And install GPU-Z to be sure Afterburner is not lieing to you :). Always double check

Always double check I have an older one, the model that was factory OC'd to 1100MHz, but I could push it to 1200MHz no problem. However, that factory OC also came with a factory 1.25V, so undervolting makes a huge diff on my card. Mine didn't work until I set the "Force constant voltage" option.I don't know about the newer cards, so you're prolly right.
