voltage does go up past 1.2 v when using Overboost. Problem is that with Overboost setting of 1250mV the voltage flactuates when the gpu is under load. but stays constant when gpu is idle. Also with Overboost enabled it pushes max set voltage to the gpu when it is in 2D state, so let's say it idles @ 135mhz but still 1.250mV is supplied. I have looked for a custom bios that rises the stock voltage ceiling to 1.210mV so that the GPU can run at a constant 1.210mV while not using Overboost, and voltage drops when the GPU goes to idle 2d clocks. to me it seems the Evga Precision Overboost setting has some bugs that need to be resolved to allow to force a constant voltage over 1.2mV when under load, and allow the gpu to adjust voltage down when going to 2D clocks.
I tired looking for a custom Bios but was unable to find what I'm looking for and I don't know how to create one, maybe someone with the knowlege could create one for me that simply rises the voltage ceiling to 1.210mv without having to use overboost.
The voltage ceiling from evga and Nvidia is already 1.212, so modifying a bios to go to 1.210 is already complete.
Voltage will always fluctuate under load. This is normal. That is why the high tier K|ngp|ns cards feature voltage dip switches to counteract the droop.
Any voltage control outside of the card itself will always be constant. When using the classified voltage tool, overboost or an evbot, the voltage stays constant. Overboost should be used for benchmarking, not daily use. Same with the classified voltage tool and evbot. The classified voltage tool, evbot and precision will all drop their settings upon a reset to keep you from destroying your card from constant voltage. It is a safety feature that no creator or develop wants to leave out, because they don't want to be responsible if someone decides to be irresponsible and leave voltage extremely high and walk away.
If the voltage is being monitored through precision, I wouldn't pay it much mind unless using the true voltage feature that was enabled recently. To use that, you would need to research how to enable it since it isn't always set automatically.

Hello everyone !
I need help ..... i recently purchased a EVGA GTX 980Ti Classified .... very excited to receive the GPU , but there is one thing that i am confused about on which i need help .
GTX 980Ti Classified GPU needs a (2) 8 pin PCI e cables to power it up ..... my power supply is a cooler master 800W silent pro gold . Now the confusion part...... i have (1) 6 pin and (1) 6+2 pin cable coming directly from the power supply ..... CM has provided (2) 6+2 pin cables ..... but these cables have one 6 pin on other side ...
Can i use than cable which has 6 pin on one side and the other side has 6+2 pin to power my GPU for (2) 8 pins ?
Thank you .
Regards
Fahd.
HI Fahd, you should have adapters and be able to use those. Just leave the extra 6 pins out of the way and use the 6+2 portion.
In the future, please use your own post for your specific problem. The forums rules specifically cover hijacking a thread to present your own issue and you have already created a post with this same question on the 980ti Classified thread specifically :
