When the CPU uses power management features to reduce energy use, other components, such as the motherboard and chipset, take up a larger proportion of the computer's energy. In applications where the computer is often heavily loaded, such as scientific computing, performance per watt (how much computing the CPU does per unit of energy) becomes ...
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 article also revealed that representatives of the three largest Xbox 360 resellers in the world (EB Games, GameStop, and Best Buy) claimed that the failure rate of the Xbox 360 was between 30% and 33%, and that Micromart, the largest repair shop in the United Kingdom, stopped repairing Xbox 360s because it was unable to fully repair the ...
Overheating (combinatorial game theory), an operation on combinatorial games that approximately reverses the effect of chilling; Hyperthermia, also called sunstroke, an elevated body temperature due to failed thermoregulation; Thermal shock, the overheating of a device leading to reduced efficiency, damage or even destruction
When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.
Care should be taken not to cover machines while they are switched on as this is particularly likely to cause overheating. Trailing cables should be regularly checked for damage. Loose or poor connections in traditional electrical accessories and switchgear can cause heat to develop capable of starting a fire.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
In combinatorial game theory, cooling, heating, and overheating are operations on hot games to make them more amenable to the traditional methods of the theory, which was originally devised for cold games in which the winner is the last player to have a legal move. [1] Overheating was generalised by Elwyn Berlekamp for the analysis of ...
