4.2 IA-32 Core Frequency Selection
The Intel
®
EP80579 Integrated Processor Product Line is offered in SKUs with a
1200 MHz, 1066 MHz or 600 MHz IA-32 core frequency. The Intel
®
EP80579
Development Board is designed to use the Intel
®
EP80579 Integrated Processor's
V_SEL and BSEL signals to provide the required input clocks and voltages for each of
these IA-32 cores. For Intel
®
EP80579 Integrated Processor SKUs with the 1200 MHz
IA-32 core, V_SEL can be used to force the IA-32 core to run at 1066MHz.
Note: 1200 MHz SKUs can be run at 1066 MHz (but not at 600 MHz).
1066 MHz SKUs can only run at 1066 MHz.
600 MHz SKUs can only run at 600 MHz
Table 10 describes how to configure the Intel
®
EP80579 Development Board to support
the different IA-32 core frequencies.
