It promises to be another scandal of graphics cards from NVIDIA – this time for NVIDIA Mobility GeForce GTX 800M and 900M, which excludes the possibility of Overclocking.
The case was highlighted by a few enthusiasts who usually worked on Overclocked laptops and enjoyed higher productivity in favorite games or for the benchmarking purpose. But the problem was that some time ago, they installed the 347.09 WHQL graphics driver and they were not able to increase the frequencies of Mobility chips based on Maxwell (GeForce GTX 850M, GTX 860m, GTX 965M, GTX 970 and GTX 980m). A Similar case has been reported with the newer version 347.25 WHQL. The case was reported on the official forum so dedicated to NVIDIA GeForce graphics cards.
NVIDIA accidentally Disabled Overclocking On GTX 800 and 900 mobility
Disgruntled employees of NVIDIA on the forum (official forum) have answered to different queries that in the configuration of drivers, there were problems with Overclocking and engineers accidentally turned off this option in the latest drivers. Their intention was not to remove this function. Employees stressed again that the components in laptops are not designed with Overclocking, and increasing self-clocking can lead to damage.
Unfortunately GeForce notebooks were not designed to support overclocking. 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.
There was a bug introduced into our drivers which enabled some systems to overclock. This was fixed in a recent update. Our intent was not to remove features from GeForce notebooks, but rather to safeguard systems from operating outside design limits.
Computer components (whether those in laptops or desktop computers) really are overclocked from time immemorial and there is always a risk of damage – usually very small, which results from improper handling methods. But the problem is that none of the manufacturers cannot guarantee that the part will handle even by 1 MHz. After all, some customers choosing laptops to play, it was purchased in order to additional Overclocking components and Nvidia’s decision could lead them to “little” disappointed (as also evidenced by the comments in the right thread).
