But until then, I don't want to take too much risk. I plan on buying a GTX980Ti now (was waiting for 16nm cards). No thanks, the risk is too high I might mess up. Change all the voltages for specific frequencies. I guess your explanation is why my card crashed so easily ? I don't feel I want to waste too much time, unless I understand what is going on. I ran FurMark (and Prime64 too) for 30 minutes. I have watercooling (to make my system silent), so I'm not worried about overheating. I changed it so that the boost clock would go to 1280MHz. So I thought: let's give it a try, and see if I can push another 10%-20% out of my card.

They run at 35-50 fps (with my settings). It was fast enough for the games I was playing. And of course it crashes also as soon as I set power target to 75%, 70% etc.Īnd where would I find such a 'properly modded BIOS' ? The card is so unstable that it crashes already in the short time when it clocks up to 1506, suggesting it doesn't do the 1506 at all. I can reduce power target in A/B, 75%, 70%, whatever, no problem.īut now I use the original BIOS with its default boost of 1367. With those cards you should not use Afterburner/Precision to overclock but get a properly modded BIOS *if* you want to overclock.

are all cards where you can NOT add voltage externally. But I know the instability is there with any 'volt-locked' cards where you can NOT add external voltage, and those are more cards than you might think. * It may be this does not affect cards where it's possible to also add volts via the external tool. Because you use some external tool like Afterburner to overclock. I hopefully shed some light onto why so many people are reporting instability at lower clocks. this table is already shifted and 'borderline' and adding clocks externally just makes matters worse) With 'out-of-the-box' 'super-overclocked' cards etc. (Kepler/Maxwell uses an internal table where each clock, and there are many, is assigned a certain voltage. With an external tool this is not possible since clocks are just added but voltages are not being increased accordingly. The only 'proper' method to overclock is with a correctly modded BIOS where the internal voltage table is also giving the correct voltages to all the clocks. You tested your card at its new speed at 1506 now and all seems ok.īut say, you run a game which uses less load, or you watch a video.or there is a scene in a game which is not demanding and your GPU clocks down to, say to 1200Mhz = CRASH. This is after you added +140 to your core clock in AB. When you overclock with an external tool, matters get confusing since you may well be stable at your max boost clock, say you found 1506 is stable. It could ALSO lead to a wrong conclusion that your card is not able to handle a certain overclock while in reality it very well can. (In fact overclocking with any external tool is so bad that even the short time it usually takes for the GPU to 'step up' from a lower CLK to its max boost is often enough to have your card crash. If your Kepler/Maxwell GPU at some point is downclocking, or you force a lower Power Target.you WILL crash. What you need to know is that overclocking with any external tool is bad. (I am trying not to be too technical here and save yourself from explanations of 'voltage tables' and internal BIOS stuff) Many Maxwell/Kepler cards cannot be 'properly' overclocked with any external tool (Afterburner, Precision etc.) since this leads to instability at lower clocks. This makes sense since of course not everyone is familiar with or does want to do BIOS modding.

Most people are still using Afterburner or PrecisionX (or whatever external tool) to overclock their GPUs. I am posting this since it seems that not many are aware of this.
