GPU Boost?

[nuttysandwich]

I have a GTX 770 from EVGA (superclocked) and I remember something like you can allow your card to overclock according to temps. How do I do that? I never overclocked anything but would like an easy overclock solution.

[Godlygamer23]

It is automated with GPU Boost 2.0. You can change the max temps allowed on the GPU though. MSI Afterburner allows you to edit the temperature limit.

gpu boost already does that
if the card is running cool, it increases its clock speed, but only to a certain point

if you actually want to OC it then download afterburner and set the temp targets and everything yourself

so i just raise the allowed temp in afterburner and thats it? and what's a  good recommended max temp

I mean that will only do so much. You can manually increase the clocks, but that will limit the GPU to prevent it hitting a certain temperature. A good max temperature in general is 85C IMO - that being said, it also depends on the operating condition of the card.

Mines automatically set to 80c. If you use PrecisionX from EVGA is as simple as moving a slider. 

 

And all cards boost differently based on the silicon lottery so be aware of that.

There's a side fan blowing directly to the card and it has the ACX cooler on it, also the PSU is acting as exhaust. What do you recommend I do? increase everything?

seriously? just moving a slider? nothing complicated like afterburner?

If you want to push the card to get as much out of it as possible while remaining within operating temperature tolerances, I would increase both, but overclock one thing at a time. If you overclock two things at a time and you were to have issues, it makes tracing it more difficult. If you want to overclock both, alternate between the two and stress test each time to increase clocks.

 

For stress testing, I would use Unigine Heaven and real games.

MSI Afterburner uses sliders.

But for the temp? Maybe I missed it when I tried it.

increase both what? I increase the max temp to 85c so far and all that did was increase the power limit to 102%, what should i increase next? and what do you mean by overclocking 2 things at a time?

and the reason i want to overclock my card is because it's not cutting the grass anymore, like for rise of the tomb raider it looks like its struggling even after geforce experience and manually turning down the settings, I would prefer to run my games on high not medium

GPU Core Clock and Memory Clock.

I mean, making changes to both GPU Core Clock and Memory Clock before stress testing to ensure both overclocks actually work individually. I would turn the power limit up to the maximum, and slowly increase the clocks for the Core Clock(by say 5MHz at a time), stress test and then overclock memory, performing another stress test, alternating between the two.

Nice. Maybe it was the skin I was using.

 

OP, in my testing adjusting the temp limit or voltage limit didn't effect the boost speed. But I have a Hybrid so temps are always under control. So you might want to start with were it's boosting to.

so for the stress test i literally run the test and see if it survives? and just play a game to see if it works?

Yep, it's that easy.

Surviving is not the word I would use per se. You need to ensure there is no artifacting present in the stress test and of course that the card is maintaining the clocks while remaining within operating temperature tolerances.

I would mix the applications being run. Use Unigine Heaven to stress test the components for a bit and then play some games, especially ones that make the GPU and memory clock all the way up like Crysis 2/3.

no artifacting meaning no lagging or stuttering going on? and by maintaining clocks meaning it's not dropping? by which how would i monitor clock? and my card only has 2gb of memory if that matters.

Artifacting:

 

 

In the context of overclocking, memory instability will cause this.

Stuttering just means it can sustain a proper frame rate to give a consistent, smooth experience, though I have had that as an unstable overclock before on my 560 Ti. By artifacting, I'm mainly referring to graphical glitches that occur once overclocks become unstable.

You can use MSI Afterburner's feature that allows stats to be displayed in 3D environments. Bear in mind that Precision X can also achieve this functionality(they're based on the same software which is RivaTuner) so if you prefer that application, that will work too. The amount of VRAM is not relevant when overclocking.

ahhh the black boxes, thank you

They can appear in a variety of ways; you will know when you see it. No need to panic; lower memory clock by 10 mhz or until the artifacts cease.
