Initially, Intel Xeon processors were designed for servers and workstations, but compatibility with motherboards equipped with LGA 2011-3 connector, as well as the tendency to rapid loss in price made them popular in certain circles. Such processors not only offer more cores than desktop counterparts, but also allow you to work with a more capacious cache. In a number of tasks, this allows you to gain a visible advantage, so enthusiasts continue to study not only the documented functions of Xeon,
but also their hidden capabilities.
Participants in the AnandTech conference this year found a way to instill the Haswell-EP generation Xeon v3 processors with the ability to more aggressively assign frequencies in Turbo mode. Initially, the higher the frequency of the core, the fewer active "competitors" it has. This is done to maintain the heat balance and a reasonable consumption of electricity. However, enthusiasts have found a way to change things by modifying the microcode of motherboards and installing special
drivers with the removal of certain Windows components. The complete procedure is described by the reference above.
Some followers of this experiment report that they were able to get the 18-core Xeon E5 v3 processor to run at 2.8 GHz for all cores. At the same time, reducing the number of active cores to ten pieces allows you to set the frequency of 3.5 GHz for them.
Specific applications in which the speed of multithreaded data processing is important, from such changes benefit. The method works with the Xeon v3 generation of the Haswell-EP generation in LGA 2011-3, with a modified BIOS for a compatible motherboard. Related Products :
