 ===== Why does the "CPU Clock" under Frequency/​Voltage Control in the CMOS Setup Utility only go up to 132 MHz and not to 165 MHz as mentioned in the manual? ===== ===== Why does the "CPU Clock" under Frequency/​Voltage Control in the CMOS Setup Utility only go up to 132 MHz and not to 165 MHz as mentioned in the manual? =====
 If a 400 MHz CPU with a 100 MHz FSB is installed, the CPU clock ranges from 100 MHz to 132 MHz. If a 533 MHz CPU with an FSB of 133 MHz is installed, the CPU clock ranges from 133 MHz to 165 MHz. If a 400 MHz CPU with a 100 MHz FSB is installed, the CPU clock ranges from 100 MHz to 132 MHz. If a 533 MHz CPU with an FSB of 133 MHz is installed, the CPU clock ranges from 133 MHz to 165 MHz.
