To miners who have HD7970 or 280X. You Can easy set 715Mhz core clock, hashrate it's like with 835MHz core or more, but you can undervolt your card to only 900mV..
Only memory clock to 1500Mhz.

can you please give us some values ?
what card works with these settings and which settings ?

Sorry for delay in response, i had a busy week.
Yes, almost all card, only VTX, CLUB3d, Sapphire OC may need little more like 919-925 mV.
On Gigabyte,Asus,MSI,Sapphire Trix/Vapor no problems with 900mv.
Just set 715Mhz Core clock and 1500Mhz Memory Clock and core voltage 900mV in MSI Afterburner.
You must only know, Gigabyte WF3 cards, and Sapphire Dual-X OC 280X , have locked voltage.
But that's no problem if you know how to modify cards bios with VBE7.0.0.7b.exe from:

If you don't know i can help with that.

a lot of savings in energy and less heat generated, that's on Asus 280X DCUII. Below 900mV

What about Power consumption?Do you have a wattmeter?
