Note that Intel’s latest CPUs also have a feature called Turbo Boost that allows the CPU to run at clock speeds higher than the default speed under certain conditions. The main processor takes the BCLK number and multiplies it by 20 to get 2.66GHz (2666MHz)–this is the CPU multiplier. On the other hand, the rated speed of the i750 is 2.66GHz.
Like almost all Intel CPUs in the Core i5/i7 line, the Core i5 750 has a BCLK of 133MHz. Let’s look at the Core i5 750 CPU for a moment. For its part, AMD calls this rate the CPU bus frequency it’s commonly set at 200MHz in AMD desktop processors.
#OVERCLOCKING UTILITY FOR HP 2820H MOTHERBOARD SERIES#
In the Intel Core i5/i7 series of CPUs, the fundamental clock rate is called the base clock or BCLK (it’s usually 133MHz). Various sections of the processor take this fundamental clock rate, which acts as a kind of standard timekeeper, and multiply it to get an internal clock speed for a particular section of the CPU. In other words, since the statistical distribution in the manufacturing process is skewed toward better-quality chips, odds are that your processor is better than its rated speed.Īll CPUs have a fundamental clock rate, from which all of the other clock rates inside the CPU are derived. In general, CPU yields are so good these days that the nominal speed grade locked into a chip may be far lower than the speed that the chip is capable of running a computer at.
Processors don’t instantly melt when you overclock them because a modern CPU’s speed rating specifies the speed at which every processor in the same manufacturing batch cano run–a number that’s likely to be considerably lower than the maximum speed that your specific processor is capable of. This article will focus primarily on CPU overclocking to illustrate the core concepts (pun intended). Overclocking a Core i7 860 means pushing it to a clock speed higher than 2.80GHz. For example, an Intel Core i7 860 runs at 2.80GHz out of the box. Almost all processors ship with a speed rating. Microprocessors.Simply put, overclocking means setting your CPU and memory to run at speeds higher than their official speed grade. Memory and CPUs are intricately interconnected, and simply pumping up the speed of one or the other may not yield the performance improvements you want to achieve. We will, however, talk about core CPU multipliers and memory clocks, and how the two relate to each other.
