Kepler: The Return

First off, a bit of background about Nvidia’s Kepler and current lineup releases for those who may be living under a rock and unfamiliar with the state of the graphics card market.

When Nvidia’s Kepler GTX GeForce 680 launched amidst much hype and fanfare, it was a revolutionary step forward from the days of Fermi. The changes and advances were significant in just about every facet, and the popularity of Kepler is a testament to its own success. So where to go from there? Moving forward, the 700 series is the next natural step for Nvidia, but the advances are more modest; it’s now evolutionary, a stepping stone ahead, and not quite the giant leap we saw when Kepler launched.

So, how did we get here? After the 600 series lineup had matured, we saw the launch of Nvidia’s GTX Titan. Turns out that Titan was the answer to our collective and confused “Why?” as far as Nvidia’s product lineup goes, but it seems we didn’t know it at the time. In hindsight, it now makes sense because the GeForce GTX 780 appears to be more of an improvement and refinement of Titan, not the GTX 680.

The reference GeForce GTX 780 comes with 2304 CUDA Cores and 3GB of GDDR5 in a 384-bit bus, while core clock speed is 863MHz Base Clock. The GPU Boost clock is 900MHz, but remember, this is the minimum you can expect to achieve; higher speeds are certainly expected here with an overclocked model.

In terms of particulars on this MSI model, below are the relevant specs of the GTX 780 Gaming:

As you can see, there’s a modest overclock on the Core out of the box, while the Boost Clock also gets a minor bump as well in comparison to what we saw for the reference specs above.

Let’s talk next a bit about overclocking on the Kepler cards and how this works with GPU Boost 2.0.

    Hello how did you become the Card to 1265mhz?
    Have you flash a new Bios?


    Jake could you share your overlock settings so I can use them as a starting point for myself? Did you just use msi afterburner or is there other programs to achieve this?.


      I essentially max’d out the voltage in MSI Afterburner, and manually increased the fan as much as possible. PowerTune will limit the potential OC because of the need to balance temps against the clocks/power, so there is a bit of luck there. So the settings could be different for each card. Just max out the voltages and then start increasing your clocks until you’re no longer stable for stress testing. Back down the clocks just a bit and you “should” be stable.


        Okay cheers jake, also my max afterburner voltage is +62, is this correct or bugged? MSI Kombustor crashes if I attempt a decent overclock like yours :/ perhaps my card isn’t as good.


          It could be your card isn’t as powerful/good at overclocking. However, every card does take some time to find various combinations that might/not work. Try a few different combinations and see if you get lucky. There is certainly some trial and error! 🙂


    hello, I have the same graph, which voltage you put with that configuration? and that program you use to measure the stability?
