6870 too hot?

so my overclocked settings are: 975/1065

and it seems that when the card hit 75 degrees Celsius while stability testing in MSI Kombustor, it just froze/restart the computer.

is that a safe temp?

to me 75C is still ok but i'm not really sure what is 'too hot' for current gen card. i think your overclock frequencies are not stable which lead to froze/restart. you can try it again to see if same thing happen or turn down the clock a bit for more stable state

I haven't been able to find anywhere about the 6870's max temp.I read in a few fourms tho that people have been maxing out in the 70c's and low 80c's.

I'm guessing above 80c would be max temp.

i guess mine just isn't the card that is able to go to 975 mhz eh?

Maybe...
Are you messing with the voltage?

Crashing/freezing while running a stress test is a sure sign that your overclock is too high. Even if the temps are within normal range, you still may be overclocking too much. Back down on the clock speeds and retest. You may also up the voltage, rather than down clock. A hint: upping your memory speed will have a greater positive effect on performance with the 6870 than increases to your core speed will.

no voltage changes and i think i hit stable at 971/1070 but i noticed that i could raise the memory clock and it would still remain stable...
and thanks i think you guys gave me a nice answer ;)

Try switching to a different Temp monitor program...CPUID HW Monitor is what i use.Maybe the software in the ATI Tool is off.

What is your fan speed at?

or maybe you can try running kombustor/furmark with stock frequencies and see what happen.

If i set my fan speed to 40%, then it will stay at 65-66 degrees celsius and remain stable, but if i let it go on auto, then it will go to 75 degrees celsius and freeze on me.

Your probably not getting very much case airflow.Change the fan speed on the 6870 to 60% manualy and leave it their,should have no problems after that.

At the moment, I don't really have a case and just running an open setup. I was thinking of getting the Cooler Master Haf 922.

I just got my 6870 and watched a video of this guy doing a review on it.He was saying that the temp. reading device is super sensitive and his was going up to 80c.I have mine idling at 46c but under a load at auto fan control it will go up to 75c. Seems that it doesn't go over 40% even at extreme temps like 75c and up.I just put mine to manual at 50% it is soooo louad though,makes my other 3 2000rpm case fans seem like nothing.Besides the LOUD fan i would say its good.Defeinitly going to buy an aftermarket cooler for it sometime in the future.It's gotta be like 100DB when it's up to 80% fan.

That temp is decent at those clocks, its the vram and the vrm that you need to keep any eye on. Always try to keep the card as cool as reasonably possible so that you may get some good long years before needing to upgrade.

Okay thanks for the answer purple stank! By the way, in MSI Afterburner, you can set the fan to go higher speeds when at a certain temperatures so my fan goes up to 30% at 50c and 40% at 64-66c idle is at 27-30c. That works best for me. Have a Merry Christmas!

Your Welcome,unfornutely i didn't get the MSI version of the 6870 i got the XFX so i just use the ATI Overdrive tool.Never expected it to be as big as it is and give off as much heat as it does,it raised my idel temp of my CPU by 3c.

Goodluck

Afterburner isn't brand-specific, at least not that I know of...

you can use the msi over drive utility with the 6870 .. i have my self .. as far as increasing the voltage depending on the type of mother board you have it may be better to increase the voltage to the pci express slots seeing as how you can not use msi after burner to increase the voltage at least on my computer .. i have a gigabyte ud5 now this may be a bug or something but it wont work when ever i set it to alow over voltage .. so i just took the back door rute .. if you do this you can really increase your mem speeds and your clock i actually had mine at 1200 mhz stable with a core clock of 975 only issue was that i noticed that if you didnt set the fan to manual it would get pretty hot .. so running at 38 % isnt loud and keeps the card under 50c in my cooler master 932..
