Myth voltage overclocking Intel Core i7

Voltage or the voltage is absolutely necessary for overclocking. Voltage is not only a role in achieving overclocking, but also a big influence on the stability overclocking itself. The myths about memory voltage as voltage not more than 1.65 volts, as they may damage the processor is true. When viewed from the Core i7 architecture itself, IMC was integrated in the processor, the impact of giving excessive memory voltage can damage the processor and IMC itself. This has happened before in AMD. To avoid this AMD motherboard makers the option to limit memory voltage to avoid damage to the processor IMC. Then, how the fate of memory that has DDR3 memory operating voltage above 1.65 volts? Would still be used? In experiments conducted, the author never uses the voltage to 1.8 volts in the long term and not to be degraded in the processor or until the processor die. It turned out that the influence of memory voltage indirectly affect other stresses, particularly voltage IOH (or chipset voltage Core Voltage IOH) and QPI / VTT Voltage. Voltage IOH has a default value of 1.2 volts and QPI / VTT Voltage has a default value of 1.1 volts. In the experiment, was the effect of raising the value of this voltage stability of the system is very helpful especially in the high memory frequency and high memory voltage. The author set IOH volts Voltage at 1:25 and QPI / VTT Voltage to 1.3 volts. These values obtained at the speed of DDR3-2000 with 1.74 volts and the voltage running stable. Screenshot can be seen below.

Conclusion
Overclocking the Core i7 platform is more interesting than the previous platform. There are obvious similarities with the overclocking on the AMD platform. Of course, since both use the same architectural concept. Processor speed is no longer the absolute in getting a better performance, but other parameters such as the QPI Bus, Uncore Frequency and speed of memory, of course, contributed a significant role in improving overall performance. Ideal overclocking results obtained from the combination of processor speed, QPI Bus, Uncore Frequency, and memory speed. These components closely related to each other, this is where lies the uniqueness of overclocking Core i7.
