Hi Unwinder, Just an update from me as an early adopter of the 1080ti, to offer some feedback on the oem2 tweaks offered. I have tried GPU Tweak, PX XOC and Afterburner. No dice with all 3 with regards to voltage control on my EVGA 1080ti FE and Windows 10 install. I offer the following screenshots of Afterburner and config, I don't know if its simply my configuration but the OEM2 settings offered do not appear to work. Spoiler Spoiler Afterburner appears to see the card as a 1080ti, it allows clock control for GPU, VRAM plus working power target. The voltage control remains greyed out. If I follow the instructions to enable the voltage control by adding a new OEM2 config line the slider is greyed out. If i add some '???????' into the config line the voltage control slider does then appear however, just like GPU Tweak and PX XOC, the voltage setting appears to have no effect. Thanks.
