Guys I am having vdrop issues on my gtx 970 Windforce OC that came with bios F2.

I edited the bios and the max tdp now is 385W but the card still throttles, it drops 10-20 hz from the overclock I set and I could live with this abysmal throttling but the real problem is that when it throttles the voltage goes down to 1.190 v which is not enough to keep the card stable at 1550mhz. When the vdrop occurs I lose stability and I get random glitches.

This is the first time I have a card with decent ASIC 75,5% and I can't push it. I am going to attach my modified bios and my GPUz log . I tried multiple clocks above 1500 you can clearly see the vdrop in the voltage column, the TDP is well below 100% and I set the target temperature to 80 C° but the card doesn't go past 70 anyway. Please take a look at them and let me know if you find something wrong.
