Gtx 780ti voltage stuck at 1.187v even with custom bios

[Lord_Karango17]

Hey guys,

 

I got a 780ti at the start of Feb, and got a custom loop soon after, and its been running quite nice and cool for a while now. The problem however is that my overclocks don't seem to much better as the voltage of the card seems to be capped at 1.187v no matter ho far I crank them up in kepler bios tweaker.

the skynet bios also dosent work on my version of the card (zotac 780ti oc) due to a bios id mismatch, so im stuck playing around in KBT.

 

In msi afterburner even before I played around with the bios, the voltage control slider did practically nothing. I was pleased at first as it appeared that I had a whole 75mv to play with as oppose to the 12mv I had on the previous 760's, however at least that actually did something... on the topic of msi afterburner, the voltage, and max ov limit always seem to be tripped, even if the card is on the stock bios, and running at stock clocks/ volts.

 

I'm fairly pleased with the card, but it bothered me that im not able to change fairly fundamental aspects of the gpu, even with a modded bios...

Moving the slider does nothing, I got my friends reference one to 1.4v.

@Gofspar You need to restart the PC first. Then it should work.

I've restarted with +30mv (this was the limit where anything above would stop the voltage limit from tripping in msi afterburner), and when running unigen valley its still at 1.187v.

 

I also tried it in games as sometimes the card dosent reach the max clocks/ volts in very demanding situations, but it was the exact same...

How did you get it to 1.4v using the sliders? if im not mistaken nvidia has a hard cap at 1.212v that can only be overridden with a custom bios, and softmods to msi afterburner...

It was a custom bios, lol.

 

common sense?

 

It's hard locked at 1.4v though. after that you need a EVGA E-Power board.
