BIOS.ProcSettings.ProcCoresPerDie (Read or Write)
Description
Controls the number of enabled cores in the processor. Under certain circumstances, you may see limited
performance improvements to Boost Technology and benefit from potentially larger shared caches if you
reduce the number of enabled cores. Most computing environments tend to benefit more from larger
number of processing cores, so you must carefully weigh the disabling of cores to gain nominal
performance enhancements.
