OCing 9800GT With Rivatuner

Hey everyone

It's been awhile since I posted anything here on Icrontic but I've come across something I think you guys can help me with.

I got an nVidia GeForce 1gb 9800 GT for Christmas and have been experimenting with OCing it (why the heck not? It's a great card). I really only have experience OCing with ATItool and my old ATI Radeon X1300; I know it's a big step up :cool:


I've managed to teach myself the basics of Rivatuner and have all my profiles loaded and it works perfectly. Standard 2d is set to 350/700/110 and switches to 663/1480/975 for high performance 3d. It'll work fine for about 5 minutes with the temp only getting to about 55c but then it'll switch back to 2d settings.

Does anyone here know why it reverts? It's not possible to change it back once it does....

It's really horrible. Going from 40fps to 8 because it reverts to 2d settings :(

Any help would be greatly appreciated

    If the NVIDIA driver performs a GPU reset for any reason, the graphics card will lock into the lowest BIOS clock speed settings the card has. Before I modded my GTX 285 to increase the fan speed, it used to crash after about 20 minutes of gameplay in any game, and then get stuck in 2D mode, similar to what you describe.

    Try forcing the card's fan to run at a high % duty cycle in Rivatuner. If that doesn't help, try reducing the clock speeds in your 3D profile - if the card is crashing because it's overclocked too far, dropping back a bit will help.

    The fan settings have pre-sets for current temperature in intervals of 60% 80% 100% and system shut down at 85c. Heat is the last thing on my mind. It idles at 45c......

    I was also getting a strange monitor purple and blue fuzz at start up before I lowered the settings (I'm using the lower settings now)

    Any idea what component is causing it to GPU reset? Clock, Shader, Memory?

    Nothing in my monitoring indicates I'm pushing it too far....

    If you're getting artifacts it's either an unstable overclock or temps are getting to high.

    55c at load means you have plenty of headroom in the temps department, so your overclock must be the culprit.

    What do you mean by lower settings? Did you set everything back to stock?

    After the monitor flash? Ya. Had to go to safe mode and disable rivatuner to get my computer back up and running

    Current OC 3D settings are 550/900 from 500/900. Shader doesn't show up after updating my Nvidia software though :(

    I just updated my drivers to 196.21 and my shader clock isn't working on EVGA precision either. They will need to update Rivatuner and precision :(

    You problem was probably that your overclock was too high, so going back to your previous drivers won't hurt.

    *shrugs*


    Atleast now it loads properly when playing physx enabled games. Just won't let me change the settings without it resetting the sliders :(


    Time to wait....

    I got sick of waiting for Rivatuner or Nvidia to give out an update so I went with EVGA Precision.


    Up to 710/1500/900 right now with the temp only spiking at 57c....will post some benchmark scores soon

    Yeah the new EVGA Precision fixes the evil shader issue.

    57C under load?

    You haven't been reading the tech news lately? The latest Nvidia GeForce drivers broke most overclock utilities' functions to one degree or another. Revert to 190.38, 195.62, or wait for the Nvidia fix. It's my understanding that EVGA Precision version 1.9.1 is compatible with the newest drivers. EVGA Precision 1.9.0 works perfectly with Forceware 195.62 and earlier releases.
