Welcome to the ThinkComputers overclocking guide for the NVIDIA GK104. Also known as the NVIDIA GeForce 680, 670, and 660Ti! This guide does MAY apply to other cards in the series, but, use it at your own risk, as it has not been tested on those devices. If this is your first time overclocking, we hope this guide will be useful to you. If you’re running Intel’s latest processor technology, Ivy Bridge, feel free to check out our sister guide that’ll help you in that area.
