Overclocking

Even though we have great performance out of the box, Gigabyte always leaves a little extra for those willing to go get it.

As Turing has been power limited in every card we’ve tested, we’ll start out by just maxing out the power target which goes to a surprising 142%.

Next, we’ll run the OC Scanner function, which takes several minutes.

When it’s finally done, it gives a new voltage/frequency curve.

Hit apply and you get a small increase in clock speed.

Our stock score was 6,594 points, so this gives us a pretty solid bump in performance from a few mouse clicks.

Next, we push the core a little by hand, up to +1000 MHz which gets us a boost clock of 2085Mhz, and we push the memory up to a nice even 13GHz effective.

This gives us a sizeable jump in score again, mostly from the memory overclock.

We were able to push the core a bit more to +120 MHz or 2100 MHz effective boost, and the memory up to a whopping 15GHz effective.

And another nice jump.

… and with the memory at 15.5 GHz.

…and with the memory at 16 GHz. Yes, 4 GHz over ‘stock’.

This is about where we hit the wall, but that’s still a spectacular jump in memory speed, wouldn’t you agree? That’s nearly an 11% increase in total score.
