GTX 970 Strix overclocking

Am I correct in thinking that the voltage is locked on these cards? If so, can I easily unlock them? I prefer to use EVGA Precision and MSI Afterburner, not a fan of GPU Tweak - sorry Asus.

One thing that won't help is having only a single power connector rather than two.

There's no definitive answer to this but you reckon that theoretically +200 core & +400 memory could work?

Hey The Fear Channel !

You can only go as high as the voltage will let you, nvidia has the voltage locked.

I like precision x for the onscreen display, the best way to overclock your 970 is is set the values like you say +200 on the core and +400 on the memory and fire up a game. if it doesn't crash ALT+Tab out of the game and raise the core clock +10MHz, ALT+Enter to return to the game. keep doing this until the driver crashes then back it of 10MHz - 20MHz.

Once you get the maxmimum core clock do the same thing with the memory until you start seeing artifacts on the screen then back it off 10MHz - 20MHz.

Let us know what you end up with. 🙂

Will do mate, thanks! I like Afterburner after finding out that Precision fps is incorrect in GTA 5. What do I do with the limit sliders? Max temp and power?

As I said before, with only a single PCI connector I don't expect much 😞

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.

First 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.

Second thing is power limit, if you really want to overclock you increase it to the max which is 120%.

And now about core and memory clock. I wouldnt go as far as nate with increasing it so much at first. Most OC guides will advice to do it in smaller sstages for safety. 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. 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. 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. 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.

Thanks to you as well. However, since my PC be returned be to revisit this thing later.
