If you're looking to push your ROG Strix GTX 1070 to new heights, Nate152 is a keen contributor in the ROG forum who has prepared a quick guide to get you on your way to extra ultra performance.
Hi everyone !
For those of you that have an ROG Strix GTX 1070 and are new to overclocking, here is a little guide that will have it running at it's maximum performance. You will need a gpu overclocking tool and GPU Tweak II is a good one to use, here is a link to get the latest version. Select your operating system then click Utilities, as of now v220.127.116.11 is the latest version.
You will also need a gpu stress testing program and Unigine Valley I find is a good program to use, click the free download.
Overclocking your gpu can take a little time but to get your gpu overclocked quickly you can try my settings and see how they work for you. You'll have to enable the "Overclocking range enhancement" to get more out of the memory as it overclocks very far. To do this click the gear at the top right shown in red and check the box, also check "Apply settings each time GPU Tweak starts", this will keep your overclock settings and apply them when you start GPU Tweak. I disabled the GPU Tweak II Startup and Monitor Startup as it only needs to be running while playing games. Simply start GPU Tweak before playing any game.
Like this then click Apply
Now click Home at the top then click professional mode at the bottom right and it looks like this below. Slide the GPU Voltage all the way to the right until it shows 100 and slide the Power Target all the way to the right until it shows 120, under GPU Boost Clock select manual and slide it to +33MHZ until it shows 1868MHz, then slide the Memory Clock to +1334MHz until it shows 9342MHz and click Apply. These settings are for the ROG Strix 1070 OC, if you have the standard ROG Strix 1070 you should be able to go a little higher with the GPU Boost Clock.
To keep your ROG Strix 1070 as cool as possible you'll want to set a fan curve, 70% is the highest it will go and I have mine set to be running at 70% at 60°C. Under Fan Speed select "User Define" then click the little gear to the right and it shows this below. Move the little red boxes with your mouse to your desired temp and fan speed, 60 at the bottom is the temp and on the left is the fan speed 70%. Click Save then Apply.
Now open up the Unigine Valley GPU stress testing program, I set the resolution to 2560 x 1440, ultra settings with no antialiasing, then click Benchmark and let it run. If it crashes with the "Nvidia display driver has stopped responding", you'll need to back down the GPU Boost Clock a notch and run it until it passes, if you get artifacting (flashing dots and triangles) you'll have to back down the Memory Clock until the artifacting stops. Be sure to click Apply if you make any changes.
The GPU Boost Clock doesn't stay at a constant overclock like previous gpu's, mine goes as low as 2000MHz and at times hits 2068MHz but stayed mainly at 2012MHz - 2038MHz, the Memory Clock does stay constant and runs at 9333MHz. Some gpu's may be able to overclock a little more and some a little less so don't be discouraged if you have to lower your overclock a little.
Here are the scores of the ROG Strix 1070 in silent mode and overclocked with the settings above, the ROG Strix 1070 in silent mode shows a max voltage of 1.062V and max temp of 67°C. - 100 frames per second
Here is the link for TechPowerUp GPU-Z with ROG skin if you'd like to install it, open it twice and click the sensors tab on one.
My i7-6700K is overclocked to 4.75GHz during the tests.
Overclocked max voltage shows 1.093V and max temp shows 71°C, but with the fan at 70% the max temp was 61°C, cooler than in silent mode and scored 111.1 frames per second. A gain of 11 frames per second which is very nice but what is really impressive is the Min. FPS going from 30.5 to 48.5 for a gain of 18 FPS. What an awesome gpu the ROG Strix 1070 is, it performs very good at 1440p, runs cool and overclocks extremely well, especially the memory.
I'd like to see how well you all did and compare so please post your scores and overclocks, if you have any questions feel free to ask.
