"Undervolted" GTX 1070 - Results

Hello, 

 

I know Nvidia and all GPU manufacturers like ASUS, MSI, Gigabyte etc is overvolting all their GPUs, so the user in no circumstance should crash their card. I wanted to test how much they are overvolting, and decided to do so with Fire Strike on loop for 30 minutes. Here's what I did on my Gigabyte G1 Gaming 1070 card on all testing:

Maxed out power limit to 111 %.
+400 Memory Clock.

Stock voltage (111% pwr limit + 400mem) = 1961MHz @ 1.050V @ 73° celsius.

Custom voltage (111% pwr limit + 400mem) = 2000MHz @ 0,950V @ 68° celsius.

Tried 111% pwr limit +400mem @ 2000MHz @ 0,943V, but it could not maintain the 2000MHz, and started to downclock itself to 1974MHz. 

 

As you can see, I managed to squeeze +39 core clock with 0,100V less than stock/default, and dropped down 5 degrees.

I also dropped down idle voltage from 0,793V to 0,625V, and got lower idle temps as well. What do you guys think? Has anyone tried to "undervolt" their GPUs? Share your results if so :D

Main:  1650 v2   @ 4,6GHz   -   X79 Deluxe                -   GTX 1080 @ 2000MHz   -   24GB DDR3 @ 2400MHz / CL10

Side:   i7-4790K @ 4,5GHz   -   Maximus 7 Hero        -   GTX 1070 @ 2114MHz    -  16GB DDR3 @ 2666MHz / CL12

I'll have to pull up my laptop results as well. I did this with my MSI GT73VR Stealth due to heat considerations. I undervolted both the CPU and GPU, and the temps are much more reasonable now without much impact to performance. I got more impact (1-5 FPS) from undervolting my CPU than I did on my GPU. Stable and works, but keeps thermals well within reasonable temps. I don't think mid 80's is reasonable....

 

But that is really cool. can you post your "default" and your "undervolt" bench marks for comparison?

I dis this on my HTC one x, under clocked the cpu yo save power. I spent hours testing for a 30min bump in batter life. 

 

I under volt my 8350 to 1.3 (stock is 1.37) with no issues at all.
