How do you overclock with nTune?

[mercanucaribe]

One of the listed features is overclocking, but I can't find any setting. I tried running the nTune service, but nothing appears to happen. This 7950gx2 I bought used is overclocked to 570 and 1550 (I guess in the firmware?) and I want to set it to stock speed.

Ah, I had to accept the license agreement in the control panel.

Hm... it says those are the stock speeds. What's up with that?

hmm, download rivatuner and double check the clocks. i think they should be 500/600 (1.2Ghz effective) at stock 7950GX2 speeds.

any problems with overclocking though?

I don't know. The top of my screen "tears" sometimes, even with vsync. Once all my graphics corrupted but it was fine when I rebooted.

The GPU is at 520mhz, and the memory 1300mhz according to Rivatuner. Strange.

Edit: I use the nvidia control panel to oc my gtx.

It is under "adjust GPU settings" in the nvida control panel. When you first open ntune go to "performance" then the first option is manual tuning adjust gpu settings. Click that and then you can adjust the clock manually.
Looks like this.

Then go to custom clock frequencies and bump them up as you please.

There is an apply settings button that is not seen here which you need to click after you set the frequencies.

Don't forget to up the fan too! Hope this helped.

The clock frequency settings interface is not available in the new-new control panel without the ntune add-on. It is still in ye olde CP though. But in any case, I find the controls virtually useless in such newer drivers as they simply deny even modest o'erclocks which were previously A-OK. So, instead RivaTuner or ATITool must be used.
