Overclocking/overvoltaging your EVGA GeForce GTX 980 Ti KINGPIN graphics card on air, water, and LN2 temperatures can be fun and most of all pretty safe for the hardware, as long as it’s done correctly. This includes not only card PCB preparation for extreme conditions, but having the right software tools + capable supporting hardware(PSU) and a stable platform to test on. Taking the time and effort to prepare the VGA properly for more extreme forms of cooling and knowing some of the basics of overclocking, can go a long way to give a better understanding of exactly what is going on when you overclock your VGA at any temperature. Consider everything given below as “self-educational” and provided to assist in getting the most out of your shiny new KP card. Not only EVGA, but I think most vendors won’t warranty any hardware if it shows signs of being used and abused. Proceed with caution and at your own risk. Having patience and doing things in small steps can work wonders in providing the best user experience while keeping your hardware safe and benching over and over again.

Overclocking VGA’s today is made easy through a design like EVGA 980 Ti KINGPIN or other similar custom card. The voltage regulation components on the card and overall design/layout are much more capable than reference designs. There are also many different software tools available for adjusting voltages, fan limits, and clock speeds. Anyone can do it with a little basic knowledge of some key terms and practice. First, let’s talk about some of the major components of NVIDIA VGA overclocking software controls. Then some basic terminology/behavior of what’s going on with the GPU when you use those tools to overclock and overvolt the graphics card.

This is main item limiting performance usually, as every NVIDIA card since the Kepler era has a power limit and circuitry on the PCB to measure input power. This control does not give you any amps or Watts value, but instead provides a percentage over design specification (which varies depending on card SKU/vendor!).

980 Ti KP has three different BIOS modes, which all have different maximum power targets keeping nominal power spec the same. If you want maximum OC headroom on air/water, you can just max this setting out and it will be enough.

• GPU Clock offset – This is GPU core clock adjustment setting.
• MEM Clock offset – This is memory clock adjustment setting.
• Voltage – for increasing the power to the core (1.212V limit in Precision X) or use classified voltage controller/EVBot for higher.
• Fan speed – Always max these when pushing the card on air
• KBoost – This is critical for getting the best scores when pushing the limits. It forces the driver to P0 state on a SW level and can prevent the card from sticking low at 2D clocks in between game tests while running benches. This can hurt the overall FPS in a benchmark a lot, and usually results in slightly lower score. On LN2, its most necessary.

Always use K-boost when doing any kind of benching!

Also if you benching with VGA cable (some cards might have no display issue on digital interfaces, such as DVI, HDMI, DP when running very low temperatures), you will need use secret menu in EVGA Precision X to make KBoost working. To access secret menu open Precision X, press Ctrl+Shift+Middle wheel on mouse and extra window with experimental features will pop up.
