NVidia Puts the Kibosh On Overclocking of GTX 900M Series

An anonymous reader writes Nvidia surprised members of the overclocking community this week when it pulled OC support from drivers for its 900M series mobile graphics cards. Many users (particularly those who bought laptops with higher-end cards like the 980m) were overclocking – until the latest driver update. Now, Nvidia is telling customers not to expect OC capabilities to return. “Unfortunately GeForce Notebooks were not designed to support overclocking,” wrote Nvidia’s Manuel Guzman. “Overclocking is by no means a trivial feature, and depends on thoughtful design of thermal, electrical, and other considerations. By overclocking a notebook, a user risks serious damage to the system that could result in non-functional systems, reduced notebook life, or many other effects.”

    If the user overclocks their GPU and it ends up overheating and breaking down isn't the responsibility for that on the user's shoulders? Why does NVidia care so much? Does the law somewhere state that NVidia is still responsible for the damages since their drivers have such an option or what is missing from this story?

      What likely happened is that some laptop brand (let's just point at Alienware) was getting a high return rate, and the GPU was found to be the culprit, and a couple of idiots left the OC settings on the hard drive when they returned it, and someone took notice.

      The subnotebook/tablet/ultrabook design can literately not afford to be overclocked since the design of the laptop is purposely arranged so that it can be cooled in that form factor. Even if you run the laptop full tilt for 8 hours straight, you may eventually trigger a thermal halt and it will be dead the next time it reboots until it's booted from a stone-cold state.
