Dynamic frequency scaling (also known as CPU throttling) is a power management technique in computer architecture whereby the frequency of a microprocessor can be automatically adjusted "on the fly" depending on the actual needs, to conserve power and reduce the amount of heat generated by the chip.
Underclocking can also be performed on graphics card processor's GPUs, usually with the aim of reducing heat output. For instance, it is possible to set a GPU to run at lower clock rates when performing everyday tasks (e.g. internet browsing and word processing), thus allowing the card to operate at lower temperature and thus lower, quieter fan speeds.
Processors can be damaged from overheating, but vendors protect processors with operational safeguards such as throttling and automatic shutdown. When a core exceeds the set throttle temperature, processors can reduce power to maintain a safe temperature level and if the processor is unable to maintain a safe operating temperature through ...
The selection of a heat sink may end up with overheating (and CPU reduced performances) or overcooling (oversized, expensive heat sink), depending if one chooses a too high or a too low case temperature Tc (respectively with a too low or too high ambient temperature Ta), or if the CPU operates with different computational loads.
Single-GPU configurations do not suffer from this defect in most cases and can in some cases output a subjectively smoother video compared to a multi-GPU setup using the same video card model. Micro stuttering is inherent to multi- GPU configurations using alternate frame rendering (AFR), such as Nvidia SLi and AMD CrossFireX but can also exist ...
This is generally known as Thermal Throttling in the case of reduction of clock speeds, or Thermal Shutdown in the case of a complete shutdown of the device or system. Cooling may be designed to reduce the ambient temperature within the case of a computer, such as by exhausting hot air, or to cool a single component or small area (spot cooling).
A cryptographic accelerator card allows cryptographic operations to be performed at a faster rate.. Hardware acceleration is the use of computer hardware designed to perform specific functions more efficiently when compared to software running on a general-purpose central processing unit (CPU).
It detects response problems from a graphics card (GPU), and if a timeout occurs, the OS will attempt a card reset to recover a functional and responsive desktop environment. However, if the attempt was unsuccessful, it results in the Blue Screen of Death (BSOD). The recovery tries to mitigate the scenario where an end user superfluously ...
