Gigabyte GA-780T-D3L - CPU and PCIE Clock Settings; DRAM Configuration and Timing

BIOS Setup - 32 -
CPU Frequency(MHz) &
Allows you to manually set the CPU host frequency. The adjustable range is from 200 MHz to 500 MHz.
This option is congurable only when CPU Host Clock Control is set to Manual.
Important It is highly recommended that the CPU frequency be set in accordance with the CPU
specications.
PCIE Clock(MHz) &
Allows you to manually set the PCIe clock frequency. The adjustable range is from 100 MHz to 150 MHz.
Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto)
HT Link Frequency &
Allows you to manually set the frequency for the HT Link between the CPU and chipset.
