Have you tried reducing frequency by 13-26mhz just to see if it fixes it?

Instability can be random like that.

Just like how a CPU can be stable in P95 full load but crashes on games with less load.

So first try with MaxAir bios was a partial success. I did not have the sliders but I move the rest to be 600mv idle and it worked however my voltage was at 1.155v.(this boosted to 1416) Now trying another bios with fixed sliders.

This one works for me:

Modified:
Boost goes to 1344
Memory: Stock:
Power: 450W
Core: 1.25v
0-RPM: yes
Target temp: 90
Max temp: 100

My videocard Evga 980TI SC+ ACX2.0 is hitting Voltage_Limit according to Evga Precision.

NOTE: Nevermind this one crashes the PC. Had to use integrated video to recover the videocard.

wow, spent a good 3hrs uninstalling and reinstalling different drivers and only the 385 worked for me.. i should have opened this forum much sooner.

im currently using this bios for my 980ti AMP(basically a reference card) http://www.overclock.net/attachments/32340

can anyone help me modify this to be compatible with the new drivers? thanks in advance

It would be better to customize the original latest AMP bios.

What clock speeds and voltage are you stable at

So after a lot of testing, I am no longer able to get my previous stable overclock, which was with the MaxAir bios(450w Power limit, 1.25v fixed), maintained 1290 as default and 1480 with overclock and power slider to max:
980Ti-SC-MaxAir.zip 152k .zip file

Now using a modified bios with unlocked voltage sliders:
EVGA.GTX980Ti.6144.150527-Sliders.rom.zip 152k .zip file

I used this bios, which has the "hidden sliders" unlocked, however now the card does not really want to go above 1.230v(as measured by Precision), and it trips some kind of voltage limit and throttles down to 1.155, which brings the overally freqency down.

If I modify the unlocked bios, with the same settings as the MaxAIr bios, the power mod does work, however I think its tripping some kind of overcurrent protection and the display shuts down and PC requires a reboot.

If somebody with more experience with BIOS editor wants to take a crack, please do.

Note: I am also still to find a bios with 3 unlocked sliders. The one above has 2. Card is EVGA 980TI SC+ ACX2.0.

Stock bios:

im using 1.230v contant on all load, i guess that is the one causing this driver install issue.

my stock clock is 1291mhz and overclocks to 1470mhz stable.

hope someone can modify the original 980ti Amp bios to max the voltage at 1.230v on heavy load and a stock clock of 1291mhz. thanks!
