A few questions about NVIDIA GPUs

Guest · Aug 18, 2016

Hi, I'm planning to buy a GTX 1070 soon and I have a few questions.

1) How exactly does GPU Boost 3.0 work? From what I've understood it alters the clock based on temperature. Does it alter the voltage in any way?

2) Do I have to enable it in any way? Will it work even if I don't install Afterburner/Precision?

3) Do I affect its (GPU Boost's) performance if I change the target temperature?

4) Can I change target temperature without 3rd party software? E.g. in NVIDIA Control Panel?

5) If I change target temperature does it directly change the fan curve? Would changing it
override a fan curve I had set before that?

6) What exactly are "Device rules" in NVIDIA Control Panel? From what I've understood you can change the fan curve there as well? (screenshot I found on the web: http://i.imgur.com/2ddXO.png) Would that still be applied if I exit the Control Panel?

7) What are some other things you can do with Device rules?

8) By the way, in the screenshot I linked above there are some sliders for graphics and memory clock but I thought you couldn't overclock in the Control Panel. Isn't that true? Also there is a voltage area that seems to be grayed out. So, is it supposed to be able to change voltage as well? :??:

9) I don't even know if these "Device rules" are included in the latest Control Panel. All the information I found about them is generally pre-2014.

I may remember some other questions I've had in my head, so I'll post them later.
Thanks for any information shared!

Anybody?

Boost kicks in as needed for over and above the core clock speed, with Boost 2 it will go a little further till it hits a predetermined temp. It's automatic. Target temp will play in yes. Changing is done through the OC software that comes with the card or a third party app. Fan curve I'm not positive on it may be dependent on the individual card and it's software.

Thanks for the reply!
I just didn't get anything from questions 6 - 9. The thing is, I don't have an NVIDIA card at the moment to check that, so if you have a card with Control Panel installed, could you just check that?

GPU Boost 3.0 takes into account temperature, voltage and current.
Depending on all three of them it will try to set the highest possible GPU clock. The point is that there is a frequency for every voltage step (looks like a curve).
It works out of the box and you have no way to enable/disable it.
The most convenient way to play with your card is with MSI Afterburner or EVGA Precision. They allow you to alter power, voltage and temperature limit as well as fine tuning of the frequency per voltage step.

Thanks for the reply!
Could you please elaborate on questions 5, 6 and 8?

n0ns3ns3 · Aug 23, 2016

5 - no. Fan curve is not affected by changing any limit. with software i mentioned you can change the fun curve or set it to manual or create additional profiles.
the control panel is not the best way to play with card settings. so I'm not really familiar with it. The only feature I used in control panel is Fast Sync. If you do not have G-Sync monitor, enable Fast Sync globally and do not enable V-Sync/triple buffer in games. It prevents screen tearing when the FPS exceeds monitor's refresh rate.

n0ns3ns3 :

Yeah, I know what Fast Sync is, but if I enable it in NCPanel, then I leave in-game V-Sync off, right?
BTW, do you prefer Precision or Afterburner?

n0ns3ns3 · Aug 23, 2016

Yes, fast sync enabled - have to disable in game V-Sync.

I use the Precision with the latest card - It's from EVGA so I tried it. It also has the OC Scanner utility that had no equivalent in Afterburner.
Before that, I used the Afterburner and they are almost identical in terms of features. The "significant" ones are OC Scanner in Precision and availability of CPU utilization in OSD of Afterburner.
Basically, they are different skins of the same SW beneath.
You might want to use vendor specific version (every major vendor have one) to control LED lightning of the card.
Regarding the card model choosing, the difference in performance between cheapest and most expensive card is next to none. The major difference is cooling solution, aesthetics and warranty terms.
The build quality is important but not critical - the improvements in overclock are minor at most.
I personally like the EVGA as they have the best support/warranty terms. They allow you to remove the cooler (to clean, replace thermal paste, install aftermarket cooler like liquid) without voiding warranty. And AFAIK they are the only company that will accept RMA on coil whine.
From their models, I'd pick today the:
EVGA GeForce GTX 1070 SC GAMING ACX 3.0 Black Edition - 429$
or
EVGA GeForce GTX 1070 FTW GAMING ACX 3.0 - ~450$ if you want highest quality build + LED lightning.
The non black edition SC card is too close to FTW in price to consider it.

About the OSDs, in the Afterburner you have to enable it in some "RivaTuner Statistics Server". Never really understood what that really was. I know it used to be a program and Afterburner was built on top of it, but why does that window pop up in the Afterburner? Also, I've seen you can enable OSD in Afterburner's settings (without that RTSS window). Is that the same thing?

n0ns3ns3 · Aug 23, 2016

Yeah, they (precision and afterburner) use the same mechanism for the OSD.
It can be enabled and disabled in the app settings (you will have the "server" in notification area anyway). in addition you can configure what is displayed, the position and the color as well as hot-key to toggle it. Sometimes i want to see it for a moment, but mostly it's just a clutter on the screen.

n0ns3ns3 :

Sorry, I didn't ask if Precision and Afterburner used the same mechanism, I asked if there's a difference between setting OSD in Afterburner properties (under "Monitoring") and in RTSS (under "On-Screen Display" and "More" at the bottom).

But why did you say Precision and Afterburner used the same mechanism anyway? Newer Precision builds aren't built on RTSS like Afterburner, right?

Nevermind, figured it out.
