NVIDIA 600-Series (Kepler) Overclocking Guide
Posted: Tue Jun 19, 2012 12:44 pm
If you own a 600-series Nvidia (Kepler) card, this is one of the best overclocking guides I've ever used:
~~The GTX 670 Overclocking Master-Guide~~
Introduction:
With the mass-popularity of the new Nvidia GTX 670, and the constant influx of questions related to overclocking them, I've decided to write an all-inclusive master-guide to overclocking them that should help most people get off to a strong start with their new 670's. All of the Kepler-based GPUs (670, 680, and 690's) are a very unique breed of GPU. Gone are the days of manually increasing voltage to stabilize an otherwise unstable overclock. Now, the user must use a great deal of finesse, and a ton of trial and error, to maximize the potential of their overclock. We now have to worry about dynamic clocking, dynamic volt changes, temperatures, and power draw in-order to reach a maximum stable overclock.
Note: Even though it's written for a GTX 670, it applies to the 680, 690 as well as they share the same PCB and Kepler-based GPUs.
Here are my 3DMark11 scores: http://3dmark.com/3dm11/3689720 using a single EVGA GTX 670 FTW overclocked to 1238 MHz (Max Boost Freq) on my ol' trusty Bloomfield i7-950 that's also overclocked to 4 GHz.
(3DMark11 incorrectly lists the GTX 670's core clock at 705 MHz, but the benchmark was still run at full load with no step-down, thermal or power throttling. This is a reporting bug in 3DMark11 with Kepler cards).
