Overclocking Simplified with Afterburner

I need a little guidance here.. mostly with the voltage tweaking. Correct where I'm wrong

-You want to keep the Core Voltage low and this is only raised to stabilize higher clock speeds. I assume if you can ramp up the core and memory clock and keep this low you're lucky.

-Power Limit. I don't touch this or the temp limit. Not sure what it means

-Core Clock. Higher is better

-Memory Clock. Higher is better

-Fan Speed. Raise this until temps are stabilized in the 60-70 range while gaming.

Is that for your new 780?

Higher is not automatically better. Use a good benchmark program to make sure you're actually making gains in performance with each subsequent increase in core or memory clock. Overclocking too far can actually decrease performance, even if it's still stable.

You can leave most fans alone since they have power profiles that will adjust the speed depending on the temperature of the card.

Power limit, slide it all the way

Raise voltage to +.38

Raise Core clock 100mhz, run a benchmark. See how it goes. Fine, add more, benchmark. Keep going until you become unstable.

Default Core, repeat the same with memory, once you find the absolute max with both then you can combine the two and lower each to make it stable

Also, make sure you have OSD turned on in Afterburner so you can watch your temps and voltage, if the voltage gets throttled due to heat, you'll need to work on the fan profile to keep it below that.

Also, if you experience throttling, just check your power usage and lower the clocks a small tad, like 25mhz each to see if it goes away. If you want higher clocks, find skyn3ts bios and flash your card to remove that bs.
