A customer observed that according to Task Manager, their CPU was running faster than the maximum speed. How is that even possible?<\/i> <\/p>\n\n\n
\n\n\n\n
Utilization<\/td>\nSpeed<\/td>\n<\/tr>\n
66%<\/td>\n2.90GHz<\/td>\n<\/tr>\n<\/table>\n<\/td>\n\n\n\n\n\n
Maximum speed:<\/td>\n2.50GHz<\/td>\n<\/tr>\n
Sockets:<\/td>\n1<\/td>\n<\/tr>\n
Cores:<\/td>\n2<\/td>\n<\/tr>\n<\/table>\n<\/td>\n<\/tr>\n<\/table>\n

The processor’s maximum speed is 2.50GHz, but it’s running at 2.90GHz? I know that athletes give 110% effort<\/a>, but this processor is giving 116%! <\/p>\n

This is a feature of Intel Turbo Boost Technology 2.0<\/a>, which runs a processor above its rated frequency if they are “operating below power, current, and temperature specification limits.” <\/p>\n

To me, this sounds like the CPU can dynamically overclock itself. <\/p>\n","protected":false},"excerpt":{"rendered":"
