Core Voltage not Changing?
Core Voltage not Changing?
I've just attempted to overclock my GTX 960 2 GB with msi afterburner. Yet I've observed that during full load, the monitored GPU voltage stays at 1.212V, no matter if the card uses default settings or if I've adjusted the core voltage slider to maximum. Anyone know why this is happening?
It's not incorrect, but increasing the slider only maintains the voltage at your standard level of 1.212V. Going higher requires a video card with unlocked voltage. Some cards allow this, others do not. The slider merely prevents the voltage from changing. Additionally, GPUs, similar to CPUs, operate at different clock speeds. Two identical cards won't always perform identically after overclocking. It's better to stick with +130, which is a reasonable overclock.

the core voltage slider sets the maximum default voltage. It doesn't raise it past the factory setting.
From overclocking guides I've read, I noticed that adjusting the core voltage slider can improve stability at higher clock speeds and lead to faster temperature rise. Is this accurate? Based on my experience, changing this slider hasn't produced the expected results. The highest overclock I managed was +130, but increasing the core voltage didn't push me beyond that without causing 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.
