From the very beginning of the PC the most demanding users have sought ways to improve the speed of their systems. Overclocking may in fact be pre-PC era of simpler devices, but the myth of 8088-8 MHz CPU overclocked to 12MHz with a simple change in clock crystal started the phenomenon.
Overclocking means pushing the speed of a component beyond that specified by the manufacturer. The word "clock" comes from the use of a "crystal clock, an oscillator that sets a pace which established the higher frequency components. The most simple devices operating at the frequency of the oscillator, so that a 8 MHz processor required a crystal clock at 8 MHz First overclock processors was as simple and as limited, as for example, change the clock frequency of the crystal separated by 8 MHz to 12 MHz.
When computers became more complex, a single crystal clock could no longer withstand the wide range of speeds demanded by the different data bus. Even if the motherboard could be several oscillators for specific components, we needed an extra chip to access a wider range of speed for a wider variety of interfaces. Known as the clock generator, this component generates clock signals whose frequencies are multiples and fractions of the crystal clock. The clock generators have become increasingly complex, so much so that some modern motherboards and components now support additional frequency adjustments in increments extremely small.
I am here providing you a guide to overclock Intel Core i7 920 & Intel Core i7 processor to 4.0 GHz. I had found much discussion on forums which talk about this and found several errors about overclocking. This guide is meant for the beginners who had not performed overclocking before and wants to do the same to get nice performance from their system. I have an Intel Core I7 920 Processor with Gigabyte Motherboard and 4GB RAM support. I use a 1GB ATi GPU on my system. But for playing some high end games I overclocked the same and found this thing very useful which I want to share the same with you. This guide will provide you information on overclocking the Intel Core i7 920s/930s processor.
Let’s first know about the processor:
Intel Core i7 920:
After analyzing in detail the Nehalem architecture, which is at the heart of the new Core i7 processors from Intel, we decided to test the most affordable of them: i7 920. I will return later on the i7 965, which has also been delivered, but that is a model that exists more for the image and marketing for the actual user. Running at 2.66 GHz, has a base frequency equal to the other two models 940 and 965, 133 MHz, and a factor which can vary from 12x to 20x at rest in normal use and 22x with the Dynamic Speed Technology or Turbo mode, to set. His QPI link, it is 4.8 GT / s, cons 6.4 GT / s for the model Extreme. Core i7 LGA1366 for the high end, but another socket for the machine.
Both sockets should then live for at least one or two generations, Intel has decided to divide its market into two incompatible platforms between them: the expensive motherboard that uses the expensive processors and motherboards that use affordable processors affordable. As it was currently impossible to use a Pentium E X48 motherboard. An approach diametrically opposed to that of AMD, although it often changes recently socket ensures compatibility between different models. The question remains what will happen in practice for both founders and how consumers will approach the most sensitive.
Moreover, in terms of cooling, I recognize that Intel has not sought to promote its processor excessive merely because the depth to provide a simple reference model. It is the same memory as I had enjoyed a simple kit 3GB DDR-3 1066MHz CAS, which is mainly characterized by its compliance with JEDEC standard. Intel would therefore probably more show here its commitment to upholding the standard that the performance at any price.
Intel Core i7 930:
It seems that things have changed since according to some of our sources among the manufacturers of motherboards, this product has just made its appearance. It is scheduled for first quarter 2010 and will replace the current i7 920. Not a big deal or raise the interest of the socket LGA 1366 platform because it will no question that a frequency of 2.88 GHz up to 3.2 GHz in Turbo mode . On the side of the i7 970 , the model with six hearts, but not part of the extreme range, it will take patience by cons.
Using a socket LGA unsurprisingly 1366, the Core i7 930 will carry 8 MB L3 cache. This quad-core processor will benefit from Hyper-Threading and integrate a memory controller, DDR3 triple-channel. The TDP will reach its next 130W. Big interesting current platform, the next models LGA 1366 will feature six cores and will run on current maps, even if the first model in the range will fly over one by its price: the processor will 980X Extreme Edition, offered at $ 999. A Core i7 970, which also has 6 cores, is expected in the future, but a priori not before the summer. Finally, we note a little quirk: the Core i7 950 (3.06GHz) and 960 (3.2 GHz) are worth the same price.
