Rodrigo - I'm using Asus GPU tweak because the card was from Asus but the process should be the same. I'd highly recommend grabbing GPU-Z http://www.techpowerup.com/gpuz/ and switching to watch the sensors tab while overclocking. I find the manufacturer's monitoring tools to be lacking. Then I'd load up the AE benchmark file I posted in the beginning of this thread to test the tweaking. So I discovered two very important things when doing this - fan speed is critical for OC on the titan, because the card monitors its own temp separate from the OC interface, and 2) Don't touch the memory clock or voltage settings. At all. When first overclocking I'd notice that as soon as temps hit 75c+ the card would throttle down. Then I loaded up GPUZ and saw that happen in real time, the clock speed would jump between 640 and 900 mhz seemingly at random. This was when I had been playing with the min. voltage and memory clock. So first set the fan speed to manual and bump it to 65-75% fan speed. apply setting and watch the temps drop. Instead of thinking like an old card, where you are giving it explicit instruction to OC, you have to think of giving the Titan "suggestions" - you provide optimal conditions for it to overclock itself! It has very intelligent heat and voltage regulators outside of the user's control. So after you give it the thermal overhead by forcing the fan faster, keep increasing the GPU clock in increments of say, 20 mhz. Now because this not an "explicit" speed for the clock to run at, you can push this pretty far. After increasing fan speed I got the boost clock to 1110 mhz, and very stable. The card set its own voltage to around 1050mV. No fluctuations in clock speed while rendering in AE. This killed the benchmark at 3:40, my fastest time ever. Watch the clock speed in GPU-Z to verify it's staying pegged. I'd love to see your results. Every card is different so you may have to play around with it.
