post #1 of 7

whats up guys. whenever i set my core clock to 1100MHz, it doesn't get stable even if i max the power limit and core voltage. is my card voltage locked? is there a way to exceed this limit?

If your card isn't stable at 1100MHz with the voltage slider and power target capped, then there's not much else you can do aside from trying a different OC'ing program (like if you're using AB, maybe try using Precision ... Precision is the only one of the two that can actually adjust the voltage at all on my card ... although it's still capped), or looking for an 'unlocked voltage' version of the 660ti bios (dunno if those exist, but I suppose it's worth looking ... I know they do for 670/680).

i thought Precision and Afterburner are the same? just with different layout

also will a bios mod let me increase my voltage and power limit?

They are 95% the same, but I know they must adjust voltage through different mechanisms. My card will NEVER jump above 1.162V unless I max out voltage (1.175V) in PrecisionX. Maxing the voltage in AB, however, cannot make my card go over 1.162V, nor will my card ever do so on it's own, under any conditions.

I've no idea what a Bios mod for a 660ti is able to do, nor if there even are any. I just know there's 1.212V voltage cap bios mods for 670/680 models, cause I've used one and there's a big thread about them on this very forum. Maybe ask those guys about 660ti bios mods?

i had installed a modded bios but found i could just do the same thing with afterburner, and flashed back to stock
