Set fanspeed upon detecting 3D app for 8800?

I use AtiTool to have my 8800gts o/c upon detection of a 3D app.

I tried using rivatuner to have the fan speed adjusted upon detecting 3D but it doesnt work. Anyone successful at doing that?

Followed it but still doesnt work.
Anybody got it to work for 8800 series?

 

Unfortunately their is no Apps that will currently control fan speed Automatically for the 8800 Series cards! You can only manually set the speeds with Riva Tuner or N tune!

 

I believe that the 8800 cards do not have seperate 2D/3D clocks so therefore the previous method of automatically setting the fan to increase when a 3D app. is started doesn't work.

 

Unwinder.........That method worked for the 7800 cards but it does not seem to work for the 8800 series as they do not have a lower clock rate for 2D mode.

 

Sorry Unwinder but you've lost me there.
If the 8800 cards do not have seperate 2D/3D clock speeds then I can't see how you can get the fan speed to increase automatically when starting up a 3D application.
All you can do with the 8800 is adjust the fan speed manually when needed.

 

actually what unwinder said might actually work by using "low-level" fan control. I did exactly the same as what unwinder said except i used driver-level fan control. I know there is a way to get it to work because AtiTool can set core clock upon detection of 3D on my 8800gts. I will give it a try when i have some free time

 

OK guys, I've configured 2D and 3D fan settings for my 8800GTX to automatically adjust when the core temp (since clock rate method doesn't work) reaches a predefined temperature.
Now when I start up a 3D app. and the card's temperature reaches a certain threshold the fan speed automatically increases and it works a treat.
Thanks for the tip Unwinder.

jacky89.........by the way, this was done in the low level fan settings, creating a 2D/3D fan profile then in Hardware Monitoring setting up the temperature threshold.

 

Cool. Btw, do you need to open riva tuner everytime to get it to work? Or will it load with windows at startup and sit in the background?

 

You'll need to set RivaTuner to sart up with Windows, I just have it set to load minimised in the taskbar.

 

I got it to work perfectly now too.

Now the next question is, how do I get it it to load an overclocking profile on detection of 3D so I don't have to load AtiTool along with RivaTuner?

Currently I use atitool to underclock to 250core/200mem which works marvelously and keeps temp and power usage down while working on 2D apps.

 

Good to hear you got the fan control working also.
As for the auto overclocking, I guess you could do the same as for the fan control and set your over/underclock profile to the temp. threshold.
So for instance, at idle temp you could set it to underclock the card and at a predefined load temp you'd set it to overclock.

 

Exactly. That's how I do it. On my 7950 GX2 I know that GPU_1 runs slightly warmer than GPU_0. My 3D overclock was intermittent at best so I set RT up to go to my 3D OC settings based on temp's. When I'm out of the 3D application, the core/memory speeds drop down to below stock 2D speeds when GPU_1 is <= 60 C. It works everytime. The temp's run cooler in 2D then when doing non_3D stuff.

 

Now I understand why Unwinder loose nerves sometimes...

Of course U can program 8800GTS/GTX 2D/3D oc clock switch in RT.
Then...
Of course U can use rising (3D) GPU clock for switching to higher memory clock in RT. It can be lower for 2D/3D profiles but U can trigger "special" profile with higher RAM clock!
Of course U can use rising GPU clock for higher fan speed...
Use your imagination. It all can be done.

 

That's what this discussion is all about, trying different methods to find which one works, which in turn helps others who read this thread.

If you'd read the previous posts you would know that adjusting the fan speed with the 8800 series cards using 2D/3D clocks does not work because the 8800 has just the one clock speed for both 2D and 3D.
We therefore found another way, that is you can automatically adjust fan speed by setting a predefined core temperature threshold instead of using clock speeds, but of course you already knew that didn't you??

 

At my house, I never turn on the heat or air conditioning. Ambient temps can range from 10deg C to 30deg C throughout the year. It would be cool if I can set the clocks by autodetect 3D. I'm wondering if AtiTool can do that, why not RivaTuner.
