Voltage of 970GTX is not growing

Hello, I have Gigabyte G1 Gaming 970GTX and I have unlocked voltage change in MSI Afterburner 4.1, but adding voltage by sliding to right is not affecting measurement or stability. My card has 1.225V at peak. Any advices? Thank you
 
1.225v is still quite a lot for what is basically a reference card on air, even in the craziest cards only go to 1.3v on a stock BIOS.

I don't recommend anyone flashes a GPU bios unless you know 100% what you're doing, if the bios isn't correct you will risk killing the card, and not to mention pretty sure no manufacturer will take a card back on the bases that you messed up a bios flashing.
 
I was editing voltage in my 460GTX few years ago. I am surprise how oc forum is dissuade overclocking. :)
Anyway i think im not gonna play with this at the moment.
 
we are not dissuading you matey but flashing your BIOS is just not recommended unless you really know what your are doing! If the card gets bricked = DEAD MONEY and you would have to buy a new card.

Post some GPUZ screenshots - dont forget to record what GPUboost2 is doing by having a second GPUZ open on the sensors tab, then click your mouse on the boxes till they all say 'max'

You may have just got to the wall of your core or it could be getting a bit warm
 
The 970 is locked to a voltage limit of around 1.3V. To push to that, as already said, you have to edit the BIOS and remove the restrictions—which are there for reasons other than to stop 970 owners beating 980 owners.

To add my own 2c to that, I don't recommend flashing a custom BIOS without first testing what kind of scaling your silicon is good for. The reason I say this, many 970's stop scaling well after 1500Mhz. They just stop gaining any tangible performance. Some cards keep going with increased benchmark scores, while many others stop. I edited my BIOS. I removed minor throttling by stabilising and increasing voltages. It improved my Fire Strike and Valley scores marginally, and it did not improve stability. I was recommended to do this by those with very little experience. To them, flashing a BIOS was just the thing to did. 'Oh, you're throttling. You best edit the BIOS'. 'Oh, your score is not as high as mine. You best check you're not throttling. I know you are and I know that's why your scores suck. So you best edit your BIOS'. This is not good advice.

Also, regarding the point about performance issues, there seem to be a high amount of variances in scores with Maxwell. For instance, my 1560/7800Mhz G1 Gaming 970 scored significantly less than another 970 at 1500/8000Mhz. I've seen folks come in with overclocks of 1620/8200Mhz, but with benchmark scores that don't reflect the overclock. It seems that frequency—and I believe Kingpin has recently confirmed this—is not everything in Maxwell.

In general, pushing a 970 beyond 1520/8000Mhz is a little silly. If yours scales well, I guess go for it. But if you're hitting the ceiling of your silicon, no matter what frequency you put on it or how much voltage you throw at it, it'll still be hitting the same scores. I personally recommend you find your max stable overclock on the stock BIOS and accept it. 1500/8000Mhz is the sweet spot. Anything more is just gravy.
 
Its also worth noting you can clock maxwell too high and it still be stable.

At some point the scores start going back down again even if the clock speed keeps climbing.

So just smashing in volts etc may actually end up being counter productive

Yep, I've seen this happen quite often.
 
It depends on the card. Some are locked at the VRM to 1.212, some are 1.256 and 1.275, and a few will allow over 1.3. Mine are locked down at 1.275v. But at those volts, they'll run just a tiny bit over 1600.

If your card has a dual bios...I would encourage you to go ahead and flash it. If it doesn't.....I'd have to be hard up for more performance.
