The NVIDIA GeForce GTX 1070 is a pretty fast card right out of the box, so we couldn’t wait to manually overclock it to squeeze some more performance from the card.
We installed a latest version of the Gigabyte Xtreme Gaming utility to overclock the GeForce GTX 1070 G1 Gaming video card! You can use whatever software utility you like for overclocking but we thought we’d try it out as it’s been a bit since we’ve used Gigabytes utility.
In case you forgot, the NVIDIA GeForce GTX 1070 Founders Edition graphics card is clocked at 1506 MHz base with a boost clock of 1683 MHz. The Gigabyte GeForce GTX 1070 G1 Gaming is factory overclocked up to 1595 MHz base and 1785 MHz boost with its default ‘gaming’ mode settings. We know this card should have more overclocking headroom in it from previous overclocking experiences with the GeForce GTX 1070, so let’s see if we can get this Pascal GPU closer to 2,100 MHz when boosting in game titles.
The NVIDIA GeForce GTX 1070 has already proven itself to be a good overclocker, so we had high hopes for Gigabytes custom board. Using the Gigbabybte Xtreme Gaming utility you can increase the power target to 111% and if you leave the GPU Temp Target locked it will automatically increase to 92C. We pushed the GPU Clock offset to +155MHz and the Mem Clock Offset to +800MHz on our card and found it was stable in the game titles that we tested. If we went up to +160 on the GPU Clock Offset we’d get driver crashes in 3D applications.
This overclock meant that we were running at up to 2088 MHz at times thanks to NVIDIA Boost 3.0 on the core and 2202.2 MHz (8808 MHz effective) on the 8GB of GDDR5 memory. Almost 2.1GHz on the core clock and we aren’t going to complain with that!

Gigabyte GeForce GTX 1070 G1 Gaming Overclocked (+155/+800):
By overclocking the Gigabyte GeForce GTX 1070 G1 Gaming graphics card we were able to take the score of 8,110 points on 3DMark Fire Strike Extreme and raise it up to 8,752. This is a 642 point increase in our overall 3DMark score, which represents a performance gain of 7.9 percent. The overal FPS average in Graphics Test 1 went from 44.73 to 48.42, which is a 8.2% performance gain in this particular graphics test.
We benchmarked the GeForce GTX 1070 G1 Gaming overclocked to +155MHz core and +800MHz memory in a number of game titles and found that it was rock solid with nice performance gains.
For example in BF4 at 3840 x 2160 we averaged 48.9 FPS on before the overclock and 53.9 FPS after the overclock. Not a bad bump up and getting close to a stock GeForce GTX 1080 FE!
Let’s wrap this review up!
