CPU Speed Detected
This option displays the default CPU speed.
CPU Host Frequency (MHz)
This option displays the CPU Host frequency. You can set it from 200 to 450. The default
depends on your CPU frequency and the CPU installed.
CPU Spread Spectrum
The Spread Spectrum function can reduce the EMI (Electromagnetic Interference) generated
for CPU. Options: Disabled, Center (Default), Down
DDR Speed (strobe/sec)
This option displays the current DDR speed (CPU Host frequency * Max Memclock ÷ 100).
Hammer Fid control
This option displays the CPU ratio information detected by the system.
Options: The options that will be available will depend on the default value of the CPU installed.
For example, if the CPU default value is 10 then the options will be from Start up, and 4 to 9.
Note: Before you try to make any adjustments to this option, make sure that your CPU Ratio is
adjustable and has not been locked by the CPU manufacturer.
CPU Speed Setting
This option displays the CPU speed.
K8 <—> NB HT Ratio
This option allows you to set Hyper Transport frequency for Northbridge chipset.
Options: 1x, 2x, 3x, 4x (Default), 5x, Auto
K8 <—> NB HT Frequency
This option displays the result of your HT Ratio setting for Northbridge chipset.
NB <—> SB HT Ratio
This option allows you to set Hyper Transport frequency between Northbridge chipset and
Southbridge chipset. Options: 1x, 2x, 3x, 4x(Default), 5x
NB <—> SB HT Frequency
CPU Speed = Current CPU Host Frequency x CPU Clock Ratio
DDR Speed = Current CPU Host Frequency x (Max Memclock ч 100)
