Processor Settings details
The Processor Settings screen details are explained as follows:
Option
Description
Logical Processor
Enables or disables the logical processors and displays the number of logical processors. If this option is set to
Enabled, the BIOS displays all the logical processors. If this option is set to Disabled, the BIOS displays only one
logical processor per core. This option is set to Enabled by default.
CPU Interconnect
Enables you to govern the frequency of the communication links among the CPUs in the system.
Speed
The options available are Maximum data rate, 10.4 GT/s, and 9.6 GT/s. This option is set to Maximum data rate
by default.
Maximum data rate indicates that the BIOS runs the communication links at the maximum frequency supported by
the processors. You can also select specific frequencies that the processors support, which can vary.
For best performance, you should select Maximum data rate. Any reduction in the communication link frequency
affects the performance of non-local memory accesses and cache coherency traffic. In addition, it can slow access
to non-local I/O devices from a particular CPU.
