Core Voltage not Changing?

I've just tried to overclock my GTX 960 2 GB using msi afterburner. However I have noticed that when under full load, the monitored GPU voltage is always at 1.212V, regardless of whether the card is on default settings or if I've set the core voltage slider to max.
Anyone know what the reason for this is?

It is not wrong. However, raising the slider does not raise the voltage beyond your default setting of 1.212V. It just keeps it there. To raise the max voltage beyond factory max you need a video card with the voltage unlocked. Some cards are locked and some are not. All the slider does is keep the voltage from fluctuating.

Also I should add that gpus, much like cpu, all clock different. Two identical video cards are not necessarily going to get the same results from overclocking. I would suggest that you keep it at +130. That is not a bad overclock.

Alright, from overclocking guides I've seen, I gathered that increasing the core voltage slider will help you achieve stability at higher clock speeds and will cause the temperature to rise more quickly. Is this wrong? As neither seem to happen when I change that slider. The maximum overclock I could achieve was +130, increasing the core voltage has not allowed me to go any higher than this without instability.

Thank you, that makes a lot of sense. Is there a way to unlock the max voltage? If so how risky is it (my card is staying very cool at the moment, so i've got breathing room in that regard)? Finally, should I try and overclock my memory? I've already tried and got instability at just +30.

(By the way, if that picture is you I just want to let you know I admire you incredible beard!)
