Sandy Bridge processors: Limited in Overclock
This news will probably upset many people - in one of the last presentations of Intel, Which dealt with theSandy Bridge The new LGA1155, mentioned that the company will deliberately reduce the capabilities of overclocking of its future processors. This is done in order to reduce costs and simplify the manufacturing process of the boards.
According to one of the motherboards manufacturers, a small increase of 5MHz in the bass frequency failedUSB And SATA. Even according to the presentation, processor frequencies can be increased by only 3 percent, as can be seen in the next video, which was leaked -YouTube. Indeed, this is a very unfortunate, and even irritating, knowledge for Overturek fans.
The limitation is that Intel has tied all the busses together (USB, SATA, PCI, PCI-E, etc.) to one internal clock that generates a base frequency of 100MHz. The clock is integrated into the motherboards with the P67 chipset and transfers the need for an external clock generator to control the frequencies of each component separately. When performing Overclock, The frequencies of different components are raised but it is important not to touch sensitive frequencies such as that of the SATA bus, as any small change can cause instability and even damage.
It is important to note, however, that the TurboBoost technology, which enables my processors Intel Get to higher clock speeds, still working. In addition, as a half-gesture for those we planned to overclock on the Sandy Bridge processors, Intel Will provide a tool to change the product of the processors, but this tool will also be limited and will probably allow choice between pre-set multiples.
Along with the damage to the Overture enthusiasts, there is also damage to motherboard manufacturers, since the limitation removes the advantage of the overclocking capability of motherboards, which has been the main focus of competition between the various manufacturers in recent years.
"Why would you choose a particular motherboard over the other, if there is no difference in their overclocking capabilities?", Ask BitTech site.
On the other hand, According to the HKEPC website, The speed limit for theDDR3 Has been raised to 2,666MHz (!) So there is a chance that we can still perform OC to memory. However, because the speed of the computer comes mainly from the processor and less memory, even if we can perform Overclock For memories, this is still not an appropriate response.
It should be noted that Intel is still planning to market processors with an open product, the K series Unveiled this year at Computex), But these will probably be the only processors given to the Uberclock worthy of its name.
In its defense, Intel Claims that processor speeds are high enough for any acceleration to be needed, but it is interesting to see what happens in the future when processor processing is no longer sufficient.
