The real trick on these particular cards isn't so much throwing a ton of gpu voltage to them as it is modifying the boost table and the corresponding voltages on the voltage table. I can share my custom bios with you if you'd like, but disclaim all responsibility for any damage that you might do.
That sounds like my card, Palit Super Jestream though not a MSI.

MSI Afterburner allows to raise 67mV, but real GPU voltage after raising is only 1.23V. With this voltage GPU can 1444MHz. I tried to edit the stock bios with Maxwell II bios tweaker and increased power limit, voltages. Now MSI Afterburner allows to raise 93mV and 127% power limit, but real voltage is still 1.23V. Maybe something else needs to be modified to increase overclocking. Maybe I'm doing something wrong. I need all in stock but get the opportunity to raise voltage to 1.28V and power limit 350W. Can someone check my bios. Archived original and modified bios. Thanks a lot.

Some voltage controller are L2C controlled, I think that's what MSI Afterburner uses. Others are sent a simple voltage signal code to the VRM controller chip. Again you can edit the BIOS, by nVidia can issue an update in the driver to override that... and they have done it before. Real voltage control is something nVidia is trying to get rid of as that's what kills cards.
For real? So how do you get around it? shunt mod to confuse the chip?

carlstinson I have made some tweakers to my bios, i think this is what i have managed so far unlocked voltages looking around it had max ref board is 1.28volts so thats what i set it to in the modded bios, adjusted pcie draw, 6pin and 8pin draw anyone able to double check my work maybe offer some advice on what i should try adjusting to get this running better, the card is on water not hitting more than 47c also adjusted tdp and power limit this card should be at 300watts

carlstinson Hi im new here and im looking at having my bios modded for my 980ti palit ref im on water so i should be able to take a decent overclock with a modded bios, i have attached a copy of my bios below.

flue This is such a big thread so I wonder if anyone knows a BIOS that fits my ASUS GTX 980 Strix OC Edition DirectCU II?
I am running it with Asus Geforce GTX 980 20th Anniversary Gold Edition original BIOS right now but the memory is still standard on this BIOS.
I need a 24/7 BIOS that is nothing crazy but with optimized power, fan curve and frequencies that should work 100% on this card.
ASIC Quality is GPU204 with rating 79.1% using Samsung GDDR5.
Anyone got any ideas and in witch part of the thread I can find a good one for me?

Best Regards Henrik
