Overclocking Results
EVGA includes a number of tools with their cards which facilitate overclocking and while the aforementioned Precision X is the primary means of increasing clock speeds and voltage while monitoring every aspect of GPU performance, their new OC Tuner X will add another handy application to your tweaking toolbox.
OC Tuner allows a user to run a number of OpenGL stress tests on their card in order to ensure an overclock’s stability before entering an in-game environment. This really will come in handy when it comes to dialing in final clock speeds since you’ll be able to quickly to quickly determine whether an overclock will hold up under stressful conditions. It also includes an information tool called NV-Z (a riff on GPU-Z) which lists all manner of specifications for you card and could help when troubleshooting an issue becomes necessary.
With all of that being said, you guys are here for the overclocking results, so let’s get to that. Just remember that any overclock we post has been tested for hours in order to ensure stability. In addition, we maximized the Power Target in every instance.
Unfortunately, overclocking the GTX 680 SC+ above its default Boost clock of 1124MHz wasn’t all that easy without adding a bit of voltage. We topped out at a mere 1169MHz on the core which is still respectable but craving a bit more led us to some voltage tweaking….
With the core voltage set at 1.095V, we hit 1275MHz (which led to in-game frequencies of about 1330MHz) alongside a GDDR5 clock of 6360MHz. Now, the memory clock was low in this instance simply because anything above that point didn’t seem to net us any higher framerates in games. It could be that the games we were testing don’t benefit from higher bandwidth or the GDDR5’s error correction was stepping in but we’ll continue testing and update this review’s forum thread if we learn anything new.
