Like I tried to tell you, most stock bios's for reference-PCB board 1080 Ti's will not let users increase the voltage at all. This is standard for almost all reference-PCB 1080 Ti's. It's Nvidia that was intentionally trying to lock down the voltage. This is what Nvidia does with their video cards. No one with any 2080 Ti can increase the voltage at all as far as I'm aware for example. The only ones that let us increase the voltage for 1080 Ti's are the custom-PCB cards typically. And even then they're usually limited to around 1.087v - 1.10v You can change the voltage -DOWN- and under-volt it but you can not change it -UP- to increase it. The XOC unlimited bios is the only bios that allows anyone with any 1080 Ti to raise voltage above 1.10v. I'm pretty sure of that.
I would rather say, on stock BIOS we are limited by 1.093v voltage, only XOC BIOS allows us to to run higher voltage than 1.093v, this is probably biggest difference
I'm still running stock EVGA BIOS on my GTX1080Ti with 2113MHz and 1.07v and no issues, with 1.093v I have run 2126MHz and 2164MHz which are stable but temperatures cannot be higher than 33-34°C if they're higher profile/clocks 2164MHz are unstable for longer periods of time and therefore I run 2126MHz profile,I think there is still bit more in clocks, maybe something around 213x-214xMHz didn't tried push clocks bit higher
You have been unlucky with yours Ti that's for sure, I told you that last time and still think yours EVGA is dud like my Zotac RTX 2080Ti right now which wouldn't OC beyond 2115-2130MHz and still that's with 1.093v and many on RTX 2080Ti thread would OC well above 2160-2175MHz and in better case 220xMHz is possible
Most of GTX1080Ti what I owned or tried they most of them will OC beyond 2100MHz under water, Aorus Extreme GTX1080Ti this wouldn't OC beyond 2088MHz and MSI GTX1080Ti Gaming X wouldn't OC beyond 2088MHz too
Hope this helps and good luck there
