You could try. I have as low as 1.212v with my old wonky evga 970 sc

Well that all depends on the card but 5mhz isn't really that much. You certainly won't notice it performance wise but I understand a lot of us like even numbers.

This specific card is known for running hot without a profile (80c is the norm). I will enable my fan profile. I also have a pic of my fan settings below. I also wanted to note that i keep my power management in nvidia's control panel on high performance, not adaptive (which would downclock when idle and lower my temps a little).





Much better. Those power limits I set in the bios are what worked for me on my 970FTW ACX 2.0 card all the way up to 1.282v, with 1650+ on the core and 2175ish on the memory without hitting a power limit. You should be good to go.

You're nearly there already....push it.

Funny, I just got a grey screen while gaming and had to reboot the system. No idea what was that about, could it be sign of an unstable OC?

Yes. Absolutely.

Test overclocks with Firestrike Ultra....if you own Firestrike, loop graphics test 1 and 2 for an hour to get your game stable overclock set. If there's any instability in your overclock, an hour of looping FS ultra will find it......

It's funny though, I played Watch_Dogs and finished it with 1495mhz and now I get a grey screen on WH: Dawn of War II, a 2009 game. I'll try Firestrike in a while, are grey screens common or should I be worried?

Firestrike Ultra is beyond my reach lol, I'll just loop vanilla FS.

Adjust from there, depending on what you see in GPUz. Target clocks for a 970 on air should be around 1500 core clocks, and 2000 memory....each card is different, and you'll have to mess with voltages and power limits, but those are good targets to shoot for.

There's nothing at all in the stock bios that will allow you to harm your card in any way, shape or form. The voltage is locked in the bios to max out at 1.262v (on most 970s, some are less). You'll likely see a max of 1.256v. So, as long as your temps are good, move the slider all the way up and run with it.

Also...download GPUz and open the sensors tab. Use either Unigine Heaven or 3D Mark Firestrike to put stress on the GPU and test the overclock. That's not likely to give you "game stable" overclocks, as each game is a little bit different, and each driver version even more different, but they'll give a basic understanding of how to fine tune your clocks for the best performance, so you can do it for the games you want to play.

Now that you have GPUz downloaded, and the sensors tab open, watch the core clock, memory clock, voltage and pay particular attention to the perf cap performance line. The perf cap performance line will tell you exactly what's capping the performance of the GPU, so you can work around it. VREL, isn't anything to worry about. Really common. VOP, means you need more voltage to go any further. And PWR, means Power. You're at the cards maximum power target, and clocking any higher won't do you any good, because the card will just throttle itself to get itself back under the power limits.

There are ways around the power limits, but.....that's a whole different animal. Tackle this one first.

Oh...and IF you're running SLI. Open two instances of GPUz. One for each GPU. That will be important to dialing in your overclock to work well on both cards. The selector at the bottom of GPUz will allow you to select which card each window will monitor.

It doesn't need to be pretty....it needs to stress the GPU. Which it will better than anything else.... Turn the monitor off if you can't stand watching single digit fps firestrike runs, but.....FS standard isn't going to cut it.
