As a result of the controversy sparked by NVIDIA's decision to disable overclocking on the GeForce GTX 900M series of laptop GPUs, the company has issued a statement that it will reverse its policy and that overclocking features will be reintroduced with the next driver update:
As you know, we are constantly tuning and optimizing the performance of your GeForce PC.
We obsess over every possible optimization so that you can enjoy a perfectly stable machine that balances game, thermal, power, and acoustic performance.
Still, many of you enjoy pushing the system even further with overclocking.
Our recent driver update disabled overclocking on some GTX notebooks. We heard from many of you that you would like this feature enabled again. So, we will again be enabling overclocking in our upcoming driver release next month for those affected notebooks.
If you are eager to regain this capability right away, you can also revert back to 344.75.
