980Ti hits power limit

[arielfall]

I've been trying to overclock my 980ti AMP! Extreme from Zotac. Out of the gate it's about 1404 Mhz boost and 7220 Mem.

 

I've gotten up to 1490 and 7880 without any voltage increase but I'm stuck really down at about 1430 once it hits the power limit. Actually overclocking higher slows it down frequency wise. So what do I do to get around it? I've set the power limit in Afterburner to 111% but that's all folks.

 

What to do?

Much like the Titan X. If you want to override it then I suggest flashing a custom BIOS on it. My Titan X's power target limit is now 121%

I guess that's my only option then?

Like megadave said flashing the cards bios is the only way to increase the power limit beyond what comes set by the manufacturer.. (mine is able to go to 150% now with previous limit of 30%)

flash bios with 1.28v locked voltage, custom tables n increased power limit. 

 

btw can you guys help explain to me what all the different power limits are in maxwell bios tweeker?

 

I was able to get my 750 ti to 65W but there are like 4 times as many tables on the 980.

Dang. I'd really like not to have to adjust the voltage though.

You don't have to increase the voltage but obviously your overclock won't be as high. 

 

1.28 is about the sweet spot for maxwell cards.

Hhmm.. Interesting, my 780 power limit is stucked at 105% (yeaa.. I know, it's suck)

How to flash a custom BIOS? maybe i can try it on my card

Thank u so much sir.

1400mhz is still a decent overclock, any more you get isn't going to be a drastic difference.

I get about 1560Mhz on mine cooled with an evga hybrid. mines at default voltage levels. if i add any more voltage mine becomes unstable.
