When you get to stable clocks I would use all 3 programs, furmark, valley and 3dmark and run them for at least 30 minutes(furmark maybe still 20) and if theres no problems start playing games, cause sometimes OC might seem stable in those programs but wont be in gaming which would mean you still need to decrease it. When you first start noticing artifacts and other signs of instability add for example 10mV to voltage, if it still not stable add 10mV more BUT if its till not stable get voltage to stock and start decreasing by 10MHz on core and 20 on memory. TThen run program like furmark, unigine valley or 3dmark for around 15-20 minutes, if temperatures are fine and theres no artifacts increase the clocks by 20-30MHz on core and lets say 50MHz on memory and repeat the procedure. 970 overclocks quite well so they dont have to be small but I at first I would go for around 100MHz on Core and 200 on memory. Most OC guides will advice to do it in smaller sstages for safety. I wouldnt go as far as nate with increasing it so much at first. Second thing is power limit, if you really want to overclock you increase it to the max which is 120%.Īnd now about core and memory clock. The downside to this is that the fan speed is locked, and won't slow down or enter its passive mode, even when idle.I didnt get any help in my topic about my 970 Strix problems and ended up rmaing the card so maybe I can advice someone else.įirst of all my card that is under warranty now is 970 Strix OC, I am 100% certain you could add more voltage, all you had to do in Afterburner is to go to options and check "enable voltage control" and then slider in main windows is active so you can increase it, I think you could do around 37mV more than standard voltage but I wouldnt go for more than 10-20mV. As such, we set the fans manually to 50 percent, which saw a higher and more constant boost clock emerge. We noticed that the fans didn't seem to want to spin beyond 42 percent, apparently prioritising low noise over boost frequency. One issue we did notice with the ASUS card is that it initially wasn't boosting as high as we'd have expected. Download an overclocking utility: There are various overclocking utilities available, such as MSI Afterburner, EVGA Precision X1, and ASUS GPU Tweak II. The ASUS Strix card has a minor advantage on memory frequency too, as it's able to match the MSI's effective frequency of 7.8GHz whereas the EVGA edition only hits 7.7GHz – this is most likely due to the luck of the drawer. However, in practice the two perform almost identically, as both were boosting to around 1,430MHz under load. However, the higher original base clock of the EVGA GTX 970 SC ACX2 meant that an 11 percent increase here was enough to surpass by the ASUS card. We were able to increase the ASUS base frequency by 15 percent. However, that's not to say that the ASUS or EVGA cards are slouches when it comes to overclocking. The Asus ROG Strix XG27UQ is one of the best gaming monitors weve tested, but youll need. The combination of Maxwell's efficiency and MSI's hefty power delivery system clearly serves it well. The review for ASUS GPU Tweak II has not been completed yet. Even crazier is the fact that it was happy to boost to a constant 1.5GHz! Such frequencies are almost unheard of for graphics cards, especially for bog standard air cooled ones with no voltage modifications. Even with this, some intensive games still overheat the GPU and forces the PC to turn off. I've used EVGA Precision X and moved the power slider all the way down to 60 and maxed the GPU fan to 2000 rpm. It's the only card to reach a base clock greater than 1,300Mhz, which is just insane for a GPU. Hello, I currently own a ASUS Strix GTX 970 which I've had to underclock due to heating issues. As you can see, the best overclocker is the MSI GTX 970 Gaming 4G, as it reaches the highest base clock and the joint highest memory clock.
