A direct path between the source and ground then results in some short-circuit power loss (). The magnitude of this power is dependent on the logic gate, and is rather complex to model on a macro level. Power consumption due to leakage power emanates at a micro-level in transistors. Small amounts of currents are always flowing between the ...
MSI Afterburner is a graphics card overclocking (OC) and monitoring utility that allows users to monitor and adjust various settings of their graphics card. [2] Developed by MSI (Micro-Star International) and previously Alexey Nicolaychuk, developer of RivaTuner, it is widely used for enhancing the performance of graphics cards, especially in gaming and high-performance tasks.
The purpose of overclocking is to increase the operating speed of a given component. [3] Normally, on modern systems, the target of overclocking is increasing the performance of a major chip or subsystem, such as the main processor or graphics controller, but other components, such as system memory or system buses (generally on the motherboard), are commonly involved.
The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.
The power management for microprocessors can be done over the whole processor, or in specific components, such as cache memory and main memory. With dynamic voltage scaling and dynamic frequency scaling , the CPU core voltage , clock rate , or both, can be altered to decrease power consumption at the price of potentially lower performance.
The cases can differ but the usual causes are: Temperature issues, such as failure of cooling fan. Unsuited video card (graphics card) drivers. Drivers that have values that the graphics card is not suited with. Overclocking beyond the capabilities of the particular video card. Software bugs in the application or operating system.
RivaTuner is a freeware overclocking and hardware monitoring program that was first developed by Alexey Nicolaychuk in 1997 [1] for the Nvidia video cards.It was a pioneering application that influenced (and in some cases was integrated into) the design of subsequent freeware graphics card overclocking and monitoring utilities.
Dynamic frequency scaling is another power conservation technique that works on the same principles as dynamic voltage scaling. Both dynamic voltage scaling and dynamic frequency scaling can be used to prevent computer system overheating, which can result in program or operating system crashes, and possibly hardware damage. Reducing the voltage ...
