Right now i'm running 1569/4100 on my 980 which is pretty good from what i have seen online, but i'm trying to push it further and i'm able to archive 1582.5mhz but not without artifacts. I began researching online because i wanted to get every sip of performance out of it of course. But going beyond 1.275v didn't seem to do anything, i tried to go to 1.3v but hwmonitor reports 1.275v. I'm using nvflash to overclock my gpu for more stability, i have recovered it twice because i bricked it twice, i know this is my own responsibility i'm simply asking if it's possible.

Is it possible to remove this limiter? I own the g1 gaming gtx 980.

Current result: https://www.3dmark.com/3dm/25751775 <--- I'm trying to archive 5050 without overclocking the cpu anymore.

And i haven't seen my temps on the gpu go beyond 66c since i repaste the gpu. I however will not be going beyond 1.3v, i just wanted to see if a little bump of voltage would be enough.

The only way to remover the limiter would be to either modify the bios or put a different bios from a different card on there. Probably not a good idea. But you do have a duo bios so if you brick it again you can always switch to the second one and fix it. Which I guess is what you did last 2 times you bricked it. I'm guessing none of the 4 different bios on the product page helped.

Well i'm already modifying the card via the bios, i'm overclocking with nvflash & maxwell bios tweaker. But anything over 1.275v isn't being reported via hwmonitor, it still says 1.275 which make me belive that card is being limited somehow, and yes i fixed it with the dual bios.

I'm not trying to ruin it, i simply want the limiter removed. I would never go over 1.3v anyway, so i wouldn't damage the card.

Thanks for trying to help, but it seems like changing the values do actually still adds voltage, but hwmonitor doesn't want to report it. I was able to get 1582.5/4100mhz at 1.287v, i haven't seen any artifacts on timespy benchmark, but unfortunately got a lower score because of my cpu, i got higher overall on the graphics test :D I will of couse not say this is stable since it's a benchmark and not real time applications, but i will test it. But i'm happy with the results
