How to Overclock the GTX 1080, Pascal GP104, & GTX 1070
While at the nVidia GTX 1080 & 1070 unveil, we had the opportunity to interview nVidia Director of Technical Marketing Tom Petersen, who spoke to overclocking changes:
Simultaneous Multi-Projection (SMP) is also discussed in the above video.
GTX 1080 overclocking is revised heavily from previous generations. The GTX 1080 and GP104 move nVidia from GPU Boost 2.0 to GPU Boost 3.0. GPU Boost 3.0 and supporting applications from AIB partners will allow for frequency-voltage curve creation that fine-tunes voltages against various frequencies. Rather than functioning on a single slider for frequency, applications like Precision and Afterburner will now create a curve that fits your card's particular silicon.
Anyone who's overclocked knows that a high frequency may be sustainable in most games or for long stretches of time, but that some specific applications or use cases will crash the drivers resultant of the overclock. The obvious solution is to step-down the OC globally until something is stable across the board, but then we're losing OC room in the use cases that didn't originally trigger faults.
GPU Boost 3.0 supports scanners, which figure out the optimal frequency for each individual voltage point. If a particular voltage point is less stable, the frequency offset can be adjusted by the tool or by manual control. In EVGA Precision, a ScanOC tool finds the optimal setup and provides a baseline that allows enthusiasts to further tune their setup. Vendors can determine parameters for voltage-frequency curve determination by the OC scanner.
Three modes exist for the new GPU Boost 3.0 overclocking tools:
- Basic – A standard slider input.
- Linear – The line can be tilted to demand more power toward one end of the curve.
- Manual – Dial-in every voltage-frequency curve point, mostly what the scanner generates.
The GTX 1070 will take the same approach.
GTX 1080 Overclocking Results
We couldn't get the “ScanOC” tool to function for this review, and ended up giving up on it (for nonstop crashing) to go the old by-hand route. Here's our progression:
|Core Clock (MHz)||Core Offset (MHz)||Mem CLK (MHz)||Mem Offset (MHz)||Power Target (%)||5m Test||60m Burn-in|
