NVIDIA GeForce GTX TITAN Performance Review and Frame Rating Update
New EVGA Precision X and Overclocking
Along with the GTX TITAN release and the new GPU Boost 2.0 technology, NVIDIA has changed and added to the API that allows AICs like EVGA, MSI and ASUS to change and modify settings on the graphics cards. Most of the interface will look the same but there are couple of new changes.
First you'll now encounter two new "targets" for overclocking and underclocking, tied to power and temperature. The power target is the same as we saw with the GTX 600 cards but the temperature setting will adjust the target temperature. You can also set the priority for targeting between the two target options to give preference to one or the other.
GPU clock offset and memory clock offset work as you would expect - changing the base clock and boost clocks above the reference speeds. While we haven't spent much time overclocking our units yet I have seen 100-150 MHz results from several sources on the GPU clock boost which is pretty impressive.
Obviously that would mean higher temps and a louder fan, but if you are overclocking your $999 GPU you are probably ready for that.
And, don't forget, a return of the ability to increase the voltage through software on the GTX TITAN. I did ask NVIDIA if we might see this return to the current GTX 600-series cards on the market...sorry, won't be happening!
After you change your offsets and maybe move the temperature target, you'll want to head into the fan curve settings of Precision X and play around with the settings. Here you can easily set targets for fan speeds at specific temps; I don't think a couple of presets to choose from and start with would be nice to have.

This is just a quick example of an overclocked result by bumping up the temp target from 80C to 88C. Our TITAN is running at 992 MHz, a 116 MHz increase over the typical boost clock advertised by NVIDIA!
I'll have some more overclocking results (in addition to monitor overclocking tests) later so keep an eye on the home page!
