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.
It is also used in overclocking to test for system stability. [ 4 ] Although most [ 5 ] of its source code is available , Prime95 is not free and open-source software because its end-user license agreement [ 3 ] states that if the software is used to find a prime qualifying for a bounty offered by the Electronic Frontier Foundation , [ 6 ] then ...
[5] [6] This is surpassed by the CPU-Z overclocking record for the highest CPU clock rate at 8.79433 GHz with an AMD FX-8350 Piledriver-based chip bathed in LN2, achieved in November 2012. [7] [8] It is also surpassed by the slightly slower AMD FX-8370 overclocked to 8.72 GHz which tops off the HWBOT frequency rankings.
Processor performance states are defined by the Advanced Configuration and Power Interface (ACPI) specification, an open standard supported by all major operating systems; no additional software or drivers are required to support the technology. [1] The design concept behind Turbo Boost is commonly referred to as "dynamic overclocking". [2]
However, other methods exist of producing inaccurate or fake time results, raising questions about the program's future as an overclocking benchmark. Super PI utilizes x87 floating point instructions which are supported on all x86 and x86-64 processors, current versions which also support the lower precision Streaming SIMD Extensions vector ...
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.
That is, the CPU is set to run at 8 times the frequency of the front-side bus: 400 MHz × 8 = 3200 MHz. Different CPU speeds are achieved by varying either the FSB frequency or the CPU multiplier, this is referred to as overclocking or underclocking.
Enhanced SpeedStep is a series of dynamic frequency scaling technologies (codenamed Geyserville [2] and including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel's microprocessors that allow the clock speed of the processor to be dynamically changed (to different P-states) by software.
