Intel Haswell CPUs integrate a voltage regulator
In the old days, any microprocessor could overclock quite easily, only increased the frequency of the bus, were fixed frequencies PCIe and PCI bus, and slightly manipulated voltages CPU and northbridge, but since the launch of the microprocessor socket LGA 1155 it ended, at least for intel CPUs, as these were the first microprocessors clock generator integrated in the microprocessor itself .
The consequences of this measure are well known to all and overclock was reserved only for high-end CPUs, microprocessors for Celeron, Pentium and Core i3 virtually lost their ability to overclock, the Core i5 and i7 were with overclocking limited, and only the Core i5 and i7 “K-Series” can be overclocked without any artificial limitation.
From Softpedia inform us that future Intel microprocessors based on the micro-architecture Haswell will bring a controversial new feature: an integrated voltage regulator (Fully Integrated Voltage Regulator “FIVR”).
This opens up new controversies, because this component traditionally located on the motherboard, will be built into the microprocessor, which while it might bring some advantages like a more precise voltage regulation, lower temperatures and consumption could also bring some unwanted effects.
It is speculated that this could hurt some overclockers, which modify the controller to achieve best frequencies, and this component to be integrated into the microprocessor, will make it virtually impossible to modify, not to mention that if they were to damage the component, not be possible to replace it, leaving the microprocessor completely unusable.
While exposing Softpedia doubts may sound reasonable, still can not make any judgment on this feature until it comes into operation in the first microprocessors that incorporate, which will for the first six months of next year.CPU, fivr, Haswell, Haswell-DT, integrated, intel, microprocessor, overclock, processor, regulator, voltage
