My cards run 30C - 35C while loaded during bench runs using 10C chilled water, But even when I set the Precision X OC voltage adjustment to 100% (giving me 1.0620v), I still see fluctuations in card OC's and voltage.
The only way I see the OC's stay close to being locked is when I use the K-Boost feature, But even that doesn't guarantee it won't drift somewhat!
Problem number 1. 1.0625 is not your max. 1.094 is.
1: drop sli for the moment.
2: use msi afterburner 4.3 beta 4 for gtx 1080's.
3: use the curve.
4: use L key to set the voltage to say 1.081. You will move the ball going up and stop at about 2113 for 2101. Then hit the L key and apply.
5: move the core speed up to your stable 2100 or so and click apply. It may move so you will need to play with this for a minute.
6: now you have just locked 2.1 ghz to voltage point of 1.081 for card 1.
7: do not move memory, you are only trying to find highest stable clock and voltage for core.
8: set power and voltage to max.
Run a single gpu only test to see if you can get it figured out first.
Then report back.
