Hello, I've been overclocking my two 780s recently. They're stable at +125MHz core clock and at 1200 mV (maybe incorrect). Temperatures are okay so far.
My main concern is trying to push the voltage to its limit to see how much performance I can extract from these cards. When I did that, my main card only reached 700-900MHz and didn't exceed the limits in my stress tests. Why is this happening?
I'm using Heaven and Firestrike to stress-test my GPUs.
If you need more details, feel free to ask—I respond quickly! 😛

When i read about people increasing the voltage on their card to "see how much they can get," I feel uncomfortable. Have you checked your temperatures? It might be throttling. Beyond that, don't adjust the voltage too much—this could damage your card. But remember, it's your card, not mine.

Aside from that, don't adjust the voltage too much—this could damage your card. But remember, it's your card, not mine. Oh, I should add that my temps are in the 70s, so I'm fine there and they'll still throttle at 95°C even with maximum voltage.

Aside from that, don't raise the voltage too much. That's one way to damage your card. But hey, it's your card. Not mine. Oh i forgot to mention, my temps are in the 70s so i'm fine there and they will throttle at 95°C. What happens when you don't increase voltage?

When i read about people increasing the voltage on their card to "see how much they can get," I feel uncomfortable. Have you checked your temperatures? It could be throttling. Aside from that, don't adjust the voltage so gently. That's one way to damage your card. But hey, it's your card. Not mine. Oh, I should have mentioned that my temps are in the 70s, so I'm fine there and they will throttle at 95°C. What happens when you don't increase the voltage? When I have it like I do now—1200mV and +125MHz—it works fine; only it happened when I maxed out my voltage. If you're talking about stock voltage, I was crashing, if I tried to overclock, that might be because the card is already slightly overclocked from Evga and needs more power to go further.

When i read about people increasing the voltage on their card to "see how much they can get," I feel uncomfortable. Have you checked your temperatures? It might be throttling. Besides that, don't adjust the voltage too much—this could damage your card. But it's your card, not mine. I should have mentioned that my temps are in the 70s, so I'm fine there and they'll throttle at 95°C. What happens if you don't increase the voltage? When I'm running at 1200mV and +125MHz, everything works properly; it only happened when I pushed my voltage to its limit. If you're talking about stock voltage, I was crashing, but if I tried to overclock, that might be because the card is already slightly overclocked from Evga—it needs more power to go further. So are you sure your overclock is stable? Alright, good. Don't mess with your voltage. Keep monitoring your system and make sure it stays steady—then enjoy your OC.

Besides that, don't adjust the voltage too much—this could damage your card. But it's your card, not mine. I should have mentioned that my temps are in the 70s, so I'm safe there and they'll throttle at 95°C. What happens if you don't increase the voltage? When I'm currently at 1200mV and +125MHz, everything works fine; it only happened when I pushed my voltage to its limit. If you're talking about stock voltage, I was crashing, but if I tried to overclock, that might be because the card is already slightly overclocked from Evga—it needs more power to go further. So are you sure you have a stable overclock now?
