Nvidia Kepler Undervolt
Set from 987 5mv to 825 0mv the absolute minimum possible however people already measured the power savings compared to the 987 5mv and the power saved is really minimal i think it was only like 4w or so less.
Nvidia kepler undervolt. Nvidia s gk104 gpu uses the kepler architecture and is made using a 28 nm production process at tsmc. The problem is this. For example i ve been running my 1070 fe undervolted to 862 mv at the stock boost frequency of 1911 mhz and do see a bit of a performance boost and better thermals. The story is the same here with the fx 570m and the voltage must be adjusted in the bios.
To undervolt kepler and maxwell gpu s you first need to lower your power target and then increase your core clock speed to compensate. For example we can undervolt kepler generation nvidia cards in software but with maxwell generation cards it is impossible to do so and must be done on the vbios level. A power target of 75 and a core clock of 100 or 150 is probably a good place to start. Linux users have been unable to under volt nvidia gpus since the kepler days when nvidia removed that facility from the system management interface smi.
Setting the slider 13mv rounds down to 12mv and then applies the undervolt but if the slider is set to 12mv it reverts back to 0 on the slider. Undervolting your gpu can definitely give you a performance boost even at your default boost clock. Gk104 supports directx 12 feature level 11 0. With kepler bios tweaker you can still limit those min voltages eg.
Afterburner cannot apply this first tier undervolt without it manually being set each and every. Kepler bios editor lets you modify the vbios of your nvidia kepler based geforce graphics card ie the geforce gtx 600 series like gtx 690 gtx 680 gtx 670 gtx 660 and geforce gtx 700 series like gtx 780 ti gtx 780 gtx 770 gtx 760 except for gtx 750 ti which is maxwell based and requires maxwell bios tweaker.
