Overclocking the MSI GeForce N680GTX Lightning
Manufacturer: Micro-Star International (MSI)
Full Disclosure: MSI provided the product sample used in this article.
Any overclocker knows that cranking the clock speed means that power usage goes up, and in many cases to get the best overclock it's necessary to increase the voltage as well. While enthusiast motherboards with modern digital power circuits make increasing the voltage to the CPU and motherboard components easy, it's not at all easy to do with most video cards. In fact to increase voltage to a video card's GPU generally requires some soldering skills.
MSI's GTX680 Lightning is one of the first Kepler-based video cards built on a fully custom PCB, and MSI included the ability to adjust the voltage for the GPU, memory, and DLLs on the card. However, the software required to do this wasn't available at the time of my original review, so I decided not to waste time on benchmarking based on the limited overclocking I could achieve without voltage adjustment. Now that MSI Afterburner 2.2.3 is available, it's time for a full-bore overclocking run!
