I can tell u for a fact the cards dont downclock at 60C...kinda crazy to even think that rly. On my classy i was playing AC unity and when ur in the menu picking gear and all, i noticed the gpu usage goes up higher and i was using AB monitoring temps and all. Noticed when the card reached 71C ( only in this menu does it go that high for some reason ) the gpu did downclock by about 20mhz or so. Soon as i exited that menu and back in game, clock went back up to 1542 and temps went back to 57C. Not sure it does that in menu but point is card dont downclock at 60c >.> 
 
Maybe idk what im talking bout just going by what i saw today by chance, and AC unity is pretty buggy so who knows, maybe gpu was downclocking cuz wasnt needed at that time but temps say otherwise. 

F.A.O. White Dragon too.
 
My OC ran through hours of Heaven and multiple runs of 3DMark fine but Far Cry crashes to the desktop.  It's either the OC or the game that is unstable and I'm leaning towards the game...
 
EDIT: OC is crashing in Borderlands: TPS now so clearly it's the OC that isn't stable.

Aww man that stinks... just for the heck of it go ahead and install 344.16 Drivers and see if you get the same crashes. I know this driver is not optimized for FC4 but try them anyway and see what happens then let us know what you find. Fingers crossed for ya bud.

I tried 344.16 and still had the same issue.  The fact that I'm crashing to Desktop means it's the core that is too high right?  If it's memory I'd get a hard crash?

If you're crashing to the desktop, it should be the game. The card would cause a complete lockup.

Well I'm a little confused...
 
At stock voltage which is displayed at 1.206v I can add +104 to the core and +600 to the memory for final clocks of 1533/8200.  I'm pretty impressed with this as the fans don't go above 45-50% and max temps have been 65-68.
 
My confusion comes for adding voltage.  I've been under the assumption that adding additional voltage will allow me to OC the card further.  However, when I add voltage even to the already stable OC mentioned above the driver crashes.  Now I'm clearly missing something.  Can someone explain my error?
 
Thanks,
Paul

Hi Paul, I spoke with you before about my first card that was RMA'd. EVGA suggested it, and in the end the card wasn't stable at stock settings and was indeed in need of it.
 
My second card seemed to be better, but is simply not unstable like the first, so it takes longer to see that increasing the voltage in precision 5.2.x isn't actually increasing stability. It reports an increase in voltage in the monitoring software, but will for whatever reason crash where the card is otherwise fine at it's stock voltage. Strange issue and it's often met with "You aren't proficient in overclocking" yet I believe it's truly a bug in Precision 5.2.x's over voltage.
 
It's as though the card runs fine on the stock voltage of 1.225, but when I manually set it to 1.3 and it reads 1.26-1.29, it's actually lowering itself to 1.200. I can't confirm this until my dmm arrives, but I have the feeling this is why we're going from stable at stock, to totally unstable after increasing the voltage while making sure the clocks haven't increased. The same applies for if you set the voltage to 1.245 which results in about 1.225 or so under load, it just isn't stable like it is if you leave it at 1.225 on it's own. Using Precision 4.2.1 or Afterburner, you'll notice a higher voltage, and you'll be able to get a better overclock with those programs as the voltage will remain constant. Doing this I'm up to 1.243v and far more stable, but not really able to go any higher than this currently. Using the nolimitsbios didn't do much for stability or performance regardless of the voltage displaying as 1.275v in precision 4.2.1. Maybe for some reason 5.2.x needs the kingpin bios to work, though I'm pretty sure the classy tool itself works without the kingpin bios.
 
So far my best results are using precision 4.2.1 at 1.243 and I'll play with the classy tool when water blocks arrive.
 
If the problem with the games happen often enough you can ease off the OC to see if it keeps happening. If it does then try it at stock.

 The 980 Classified comes with a stock hot-clocked image and secondary BIOS with a higher power target and extended overclocking performance.

Borderlands TPS is a buggy mess, same with Farcry 4. So your OC might not be unstable. Try some other games and see what happens.

In Precision X 4.2.1, when the GPU clock line turns yellow, is that an automatic no-no overclock? Can is still be stable? (I don't have the time or patience, hoping someone's already tested it)

I just bought 2 classifieds and I got a question, One card stock clocks at 1430 out of the box, the other clocks at 1366, no overclock on either card. When run in sli I only get 1366 as it defaults to the lower speed. Its the same on all three bios. The cards are one serial number apart. Anyone else seeing this. Under K-boost the same thing. I think I should be seeing 1391 or better as the cards states 1391 under boost. I should not have to overclock to get advertised speeds. What am I missing here?
