post #9871 of 21378
Good evening everyone,

I have been enjoying my 780 classy for a few weeks now... I am on my second card, after having the 1st RMAed because of a noisy cooler. This one is not noisy and, as a bonus, actually OCs a bit better than my first card (and has a higher ASIC score, which might in part explain the better OC).

Probably due to being a better OCer, I am worried that this card is running hotter than my 1st card. In fact, in most games, the card quickly reaches the 70ºC and, most of the times, hovers around 75ºC. Certain games, like Bioshock Infinite, for example, without vsync the card can reach 80ºC. The fan profile I have is quite aggressive an is set up at temperature+10% fan speed (meaning, at 75ºC, the fans will be screaming at 85%).
In addition, in tests like OC scanner, the temperatures shoot past the 80ºC (even with the fans at full blast).

This is in contrast with my previous card, where the temperatures rarely went above 75ºC (in any circumstances). In fact, in gaming, my first card rarely reached 70ºC.

So... should I worry? Why is this card running so much hotter? Isn't 80ºC quite a lot for this card? Can I have a somehow defective cooling system?
Any opinions/suggestions would be really appreciated.

Thank you!

You said it clocks a tad higher out of the box compared to the previous card, there's some of the reason. Another possible reason is that the paste wasn't done as well as on the previous card. I would do that, remove the cooler/paste and put something new on it, try again.

I am afraid to do it!!! smile.gif I guess I can try it at some point... I am just trying to understand if I should be worried, before embarking into more "aggressive" solutions!

Could 780 classy owners on stock coolers share their gaming temps with me? Ideally, games like Bioshock Infinite or AC4...

Well once you hear back and if you choose to do it, it's easy. Take out the main 4 screws and pull it off, not too far as the fan cable is connected and you don't want that to rip-out, not sure if it would.

Then clean it up, put some new paste on and put it together. Done and dusted .. if it's dusty, do that too! smile.gif

hello to all,then my gtx 780 classified can do 1371 mhz whit 1.324V is that good overclocking capability?about temp is around 82c whit fans on max speed.

That doesn't say much- what were the other parameters in the EVBot/Classy Tool? What software program did you use to verify the overclocks? What were your temps? What else do you have in your system?
post #9877 of 21378
i7 4770k 4.6 ghz
corsair ssd 840 pro 256 gb
corsair vengance pro 1866 mhz
evga gtx 780 classified 72.5 asic quality
h 220 watercooling setup
asus z 87 sabertooth
overclocking to 1371 mhz i need to put slider in Classy Tool to 1.36.7V and on loud voltage will droop to 1.326V and will stay at that voltage during the loud.temp are around 82c and i am using gpu z to monitor voltages and graphic card clock....i am waitting for probe connector so that i can finally check voltages but i believe that readings from gpu z are not to far away from real voltages measured from dimm.
so if is card using 1.326V on 1371 mhz will be nice overclocking capability or not?thanks for your help guys.
p.s. above 1371 mhz even for quick benchmark getting too hot and i dont want to burn the card....above 1371 mhz card star to be very complicat to overclock i have a lot of artifacting and i need to put say 1.4V to reach 1398 mhz and during loud voltage droops from 1.4V to 1.367V man that is a lot of vdroop.....vrm during 1371 mhz never past 68c.is compicated to deal whit vdroop on this card for me becose is very annoying and i am not just to deal whit this ****........ng VDROOP.
i cant break 1400 mhz barrier on air.i will get waterblock next monyh and thet we will see....

My car is artifacting at 1288mhz boost with the voltage bumped to 1.212. Very frustrating cause it wasn't artifacting at all for awhile there. Heaven really stresses these cards.

Those temps are really high, and likely why you are not going any higher. The H220 by itself can't handle your GPU and CPU overclocked that high. I would imagine you can go higher with a better cooling setup.

How did you determine overclocks stability?
post #9880 of 21378
i am using unigine valley and also bf4 and call of the duty ghost,but valley is the first thing that i trust.
are you saying that my artifacting above 1371 mhz are because of temp?
