In a recent update, NVIDIA has rolled out a hotfix driver, version 576.15, to address a critical issue with its graphics drivers. This new driver effectively resolves the temperature sensor bug reported by users in the previous 576.02 driver. For more details on this hotfix, you can read about it here.
Reports have surfaced from numerous users detailing a significant temperature sensor bug linked to the NVIDIA GeForce 576.02 driver update. This update was initially intended to resolve black-screen and stability issues but has inadvertently introduced its own set of problems. Many users have noted that the GPU temperature readings are inaccurate, which can result in incorrect clock speeds and voltage applications.
The root of the issue appears to be associated with the NvAPI_GPU_GetThermalSettings API interface. Users have reported that this API can become stuck at a fixed temperature value, rendering the temperature sensor ineffective. The only reliable workaround identified so far is a full system reboot.
Discussion threads on forums such as Guru3D have further illuminated the problem. One user speculated that third-party applications like MSI Afterburner and Riva Statistics Server might be contributing factors. However, Alexey “Unwinder” Nicolaychuk, the developer of these tools, clarified that the underlying bug resides within the driver itself, and rebooting the system after sleep is currently the only fix.
The temperature sensor bug typically manifests after a system goes into sleep mode or when exiting power-saving states. Once the sensor data is frozen, the graphics card struggles to adjust its clocks and voltages appropriately. While this may impact the performance of the graphics card, users can rest assured that the built-in sensors and failsafes within modern GPUs are designed to prevent any permanent damage.
In light of the ongoing issue, PC Games Hardware has advised users to avoid the 576.02 driver until NVIDIA releases an official statement or a new driver version. NVIDIA has acknowledged the problem and categorized it as a 'known bug' in the latest driver changelog, specifically noting that GPU monitoring utilities may stop reporting temperature readings after the PC resumes from sleep.
As users await further developments, it is crucial to stay informed about updates from NVIDIA regarding this issue. The rapid release of the 576.15 hotfix driver indicates that NVIDIA is committed to resolving these bugs and ensuring optimal performance for its users.
