106% is hard locked by the BIOS, only way to up that is a bios reflash.
Depending on your benchmark you may not be able to push past 50Mhz and every chip is different.

Check if EVGA has a newer bios, perhaps there is a bug or something. Not the same card obviously, but I can get +150 without issue and probably more with the same 106% limit. Save your bios and check it out with Kepler Bios Editor to see if maybe they were cautious on the actual power draw limits.

Either edit your own using GPUZ and NiBiToR (if you choose to pursue this then I can explain more in depth) or just search up a pre-made BIOS online that has already unlocked the voltage. Then you'll need nvflash to flash your new BIOS onto your card, as well as a tool like the HPUSBBoot tool that lets you boot from a USB drive. You can install Windows 98 DOS to the drive so that you can flash it. It is way less complicated than it seems.

Sorry if my post on flashing was wrong I only have personal experience flashing Fermi BIOS's.

Sort of, you extract your previous BIOS with GPUZ and then edit that in NiBiToR as a seperate BIOS. Then you flash your new one.

WEll, no buttons here that lead to extractions.

100% = 230w.

That's an ecessive amount of power, these GPU's in games are usually a chunk below 200 at max oc - you won't ever be power limited even without raising it.

What is crashing with +50mhz and what load GPU clock is that read by evga program while it's running?
