Why is my 7950 throttling?

[futurefields]

Got home today eager to jump on some Far Cry 3, so I did. But noticed right away my frames weren't where they were. So I alt-tab out and Catalyst shows my clocks at 850/1250

I'm overclocked to 1100/1400 and you can see I have enabled +20% on the power setting. My computer has a Rosewill Capstone 650 watt psu. Anybody know what it could be? Temps also stay very low, in the 50's.

Try defaulting CCC and using overclocking software to raise powertune.

 

[cmdrdredd]

Yeah basically just use MSI Afterburner or Sapphire TRIXXX.

 

[futurefields]

I use Trixx already.

 

[cmdrdredd]

I use Trixx already.

Then you shouldn't be using CCC at all I don't think. If TRIXX isn't working properly you can try MSI Afterburner. I find it more fully featured than TRIXX.

 

[BallaTheFeared]

Did you remove the CCC settings?

 

[futurefields]

I never touched CCC settings, the sliders moved on their own to 1100/1400 after I applied settings in Trixx.

I only pulled up CCC now to check my speeds. And it shows 850/1250 on the dial, even though the sliders show 1100/1400.

 

[BallaTheFeared]

I suggest just reinstalling the driver and never accepting the agreement for overdrive...

 

[cmdrdredd]

What does TRIXX report? It has some reporting tool if I remember from when I had a 6970.

You could also run the on screen display with your clock speeds, vram usage, GPU usage, fan speed, and temp with MSI afterburner. I find this useful if I ever have odd performance to see what's going on.

I deleted Trixx and restored settings to default, now it shows proper 925/1250 @ stock (while in game during Far Cry 3)

So it only throttled when overclocked in Trixx... weird

That is odd, but you eliminated the culprit. I still say give Afterburner a shot if you're looking for something else to try.

think im just gonna leave this card at stock until i find i actually need the extra performance, all this overclock and benchmarking is starting to frustrate me.

 

[BallaTheFeared]

heh, tell me about it.. Cards are peta to overclock... So easy and yet so finicky..

 

[manutdc]

If the driver crashes due to an unstable overclock doesn't it set the speeds back to stock?Might be something to look at - even though temps may be fine the OC may be unstable and causing the driver to crash.

LOL. Has PETA tried to ban FurMark yet?

I really don't like OC video cards. You may think you have a stable OC but then in some game you will see some texture corruption.
on my 5850 I thought I got a nice stable OC and played a lot of games.. until I hit mass effect and it would give me little blips of white blotches from time to time.. removing my overclock cleared it..

What Cmdrdredd said.

I see you have overdrive enabled make the following changes, so first click set default settings in CCC, then uncheck the enable box in CCC now click apply make sure when you click apply over drive is disabled and the settings show your stock clocks. Now go into Trixx and set your OC settings and click apply this should take care of your problem. When you go into CCC it will show default settings do not enable it just use Trixx to check your settings and just leave overdrive disabled only use Trixx. I do not have your problem with the above.

whether you use AMD Overdrive or sapphire trixx you just need to maxout power control to +20% to avoid throttling. at stock voltage 1 Ghz is fairly easy to run. you can definitely run at that speed. 1.1 ghz may also work fine but you might have to test it out and tweak voltage if necessary.

 

[futurefields]

guys...

it's doing it again. power setting is set to +20% what do I do????

Also, weird thing I think it might only be doing it in Far Cry 3, hold on let me check another game. its for sure doing it in FC3.

 

[futurefields]

guh

I could have sworen I read to not use CCC with Trixx awhile back so though maybe that was your problem. Maybe switch to the other BIOS (per switch on the card) on the card and see if that makes a difference or helps?

 

[futurefields]

New update:

I reset to defaults and unchecked "Enabled Graphics Overdrive" in CCC

Trixx is set to default values still 925/1250, 0% power

During Far Cry 3 game play, GPU immediately switches to 850/1250

Boost Trixx "Board Power" to +20, and the GPU goes back to 925/1250

Is it normal I should have to boost "Board Power" even just for the factory boost overclock?

 

[futurefields]

And now Sapphire Trixx wont save my OC settings, when I reset my computer its back to stock again

 

[futurefields]

is it something wrong with my card you guys think? like its not able to remember bios settings or something?

To me after reading that it sounds could be the vc BIOS?

I haven't seen that problem on mine having to boost the BP to get stock 925/1250 on my board. The other things I would try is maybe uninstall Trixx and just use CCC to oc if it happens again then set back to default and then try MSI AB?

I am out of ideals unless to try unless you want to try a AMD driver reinstall.

Hopefully someone with more knowledge on VC than me will be here shortly to help you out.
