I have to admit that I didn't change the fan profile at all. Do I have to? The fan spins up to approx. 2500rpm. I thought I excluded the temperature factor by raising the max. operating temperature to 91 degrees celsius which I haven't seen yet.

you can try turning the fan up, I have mine on auto fan. Zotac is a good card, friend of mine has had a few.

ok, I'll try a more steep fan curve, but I found sth different:

The top three fields above the total TDP value are respectively for the PCI-E slot power (66W by default) and the first and second PCI-E power connectors on the card (75W each). You cannot modify just the total TDP value and not also increase the separate power lines maximum as if you do not the BIOS will still limit the power that the video card uses to the combined maximum of the PCI-E slot and the two additional PCI-E power connectors
referred to this the power limit extend by 3rd party software shouldn't have any effect whatsoever because only raising power limit doesn't apply when there is nothing set to deliver that more of power.

Anybody know where to find a cheap NZXT Kraken X41 so I can put it on my GPU?

Best one I saw was a used one for £68

You can try the one that Sajin at EVGA modded for me. I got up to 1620 Core Clock and 1.275v with it.

P.S. BIOS version is 84.04.31.00.F6

Sorry, that's the one he gave me after I gave him my stock BIOS to mod that I listed above. I never checked it myself, I just took it for granted that he modded the BIOS I asked him to mod. Maybe he had one already modded. It does work very well with my GTX-980 Gaming 4G boards.

I might try and do some more overclocking with my 980's as I feel they have a little more potential. What would a safe voltage actually be for say 2-3 hrs. of gaming? I can't seem to get over 150/125 stable without requiring volts. Some people have said it's ok to max it out because Nvidia (EVGA in my case) have set it to it won't do any long term damage as it's still below dangerous levels.


I'm also disappointed, I've been playing GTA 4 now at max and that game doesn't like an overclocked card at all!, which a game like that would benefit from it

unfortunately I cannot raise the voltage effectively.
I've set it to +87mv but after some time it steps back to 1,193v.
is that a normal behavior?
I've maxxed power- and temperature target which are not getting touched at all.
it never gets past 84°C temperature and 105% power.

it turns out this voltage throttling is part of the gpu boost 2.0 and I had to mod the bios to get it done.
seems quite strange to me. no I've set 1,22v as minimum within final boost stage and it works fine.
I'm very glad with the 980 series. What a great success.
Makes me kinda sad for AMD. Hopefully the got something comparable when Zen comes out for the all-AMD system. wink.gif

Thanks anyway thumb.gif

Does the BIOS downclock , down volt when not gaming or benching?
What are the default core and Mem values?

I'm still running the stock cooler, hope it will be fine with that BIOS
