I don't know what people's problem is with not being able to get more than a 109% power limit. I have a MSI GTX 770 Lightening and I've modded the bios so I have a 300% power target. (MSI After burner prevents using even higher than that, ugh). The problem with this mod is that when you add voltage it uses a lot more power. I've yet to figure out how to use this tool to my advantage over +113mv (snaps to 106 and 113 and other strange numbers higher up).
What would be REALLY great is if the mod let afterburners power target go above 300% as that's locked in the same way the +100mv sliders are locked. I have my bios letting the card use 333 watts as the 100% power target and 999 watts (locket from going further) as the maximum watts usable which comes out to exactly 300% in AB. So I've basically hit all the limits and still can't get beyond 1359mhz without getting CTD's and the occasional driver reset/crash in an extremely heavily modded skyrim.
Also, I have no idea what anything in the advanced category does at all. If you read this Rbby258 I'd like to thank you for making this tool, it needed to happen. I'd also like to ask that you name it maybe Rbby or something else (Superburner?)
Then add a version number. It'll feel more official.
Note to Jorginto (reply isn't working): I don't use Kepler bios tweaker for modding Vbioses as it's support of features has fallen behind and has some stupid limitations. (Can't set above 4000mhz memory). Svets Vbios Tuner is where it's at. Constant development and he even fixed the 4000mhz limitation in his tool the day after I submitted a bug report. WAAY Worth the $20 (and impossible to get a copy of otherwise).
