EDIT: Try this one. Also please note if its unstable, back your clocks down until it's stable. Upping the voltage, and power can make the card boost past the stable point.

Let me know.
CrazyNut,

thanks for the custom mod! I tried it and there is no difference. works the same way. I might got the wrong end of the stick originally as playing more with different voltage tables/clocks I see that it's not the power limit we see in monitoring software is the real limit - that hovers around 105-110 and rarely reaches 115. the time when the downclock/voltage drop happens doesn't coincide with the time of reaching the power limit. there is either another power limit like you're saying what we don't see and/or it's down to the logic of boosting. I guess the boost logic is somehow defined in relation to tdp/voltage steps/clock steps in the BIOS as I can see voltages appear multiple times in the BIOS, like 54 80 12 (1.212V). I also found that the voltage table 2 affecting the scale of boosting, its swing behaviour and also the default 3D clock. so there must some complete profiles in the BIOS.

In the end, I realized that a lot more settings come into play if you want to achieve overlock over 1200Mhz which opened up a whole new playground to me. previously I just used the standard output of kgb which sets both voltage tables the same and I haven't been tweaking the voltage further in software. after trying many combinations I was able to find that one single sweet spot and also the dos and dont's. I'll provide the details later but my point is that boosting pretty much ruins the overclocking close the gpu limits since it's currently not possible to achieve the highest overclock without suffering from large swings - you can either have the highest boost with a high swing (1050-1300) or a lower boost clock with a small swing (1200-1250) which ensures better performance due to a higher minimal base clock. to get the max out of overlocking, it would be great if we could find a way to control the minimum clock somehow.
