DRAM Frequency
Use this field to configure the clock frequency of the installed DRAM. Settings
are: PSB 400: 266, Auto, 333, 400, 433, 466, 500.
PSB 533: 266, 333, Auto, 400, 433, 450, 466, 500, 354 (3:4).
PSB 800: 266, 333, 400, Auto, 433, 450, 466, 500, 532, 501 (4:5),
533 (3:4).
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec-
trum function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves. If you do not have any EMI
problem, leave the setting at Disabled for optimal system stability and
performance. But if you are plagued by EMI, activate the Spread Spectrum for
EMI reduction. Remember to disable Spread Spectrum if you are overclocking
because even a slight jitter can introduce a temporary boost in clock speed
which may just cause your overclocked processor to lock up. Options: Disabled,
Enabled.
Adjust CPU Bus Clock
This item allows you to select the CPU Bus clock frequency (in MHz) and
overclock the processor by adjusting the FSB clock to a higher frequency.
Settings are: PSB 400: 100-355MHz.
PSB 533: 133-500MHz
PSB 800: 200-500MHz
DDR Clock (Mhz)
This read-only item allows you to view the current DDR clock.
Adjust AGP/PCI Clock (Mhz)
This item allows you to select the AGP/PCI clock frequency (in MHz) by
adjusting the AGP/PCI clock to a higher frequency.
CPU Vcore Adjust
The setting allows you to adjust the CPU Vcore voltage. Available options:
Yes, No.
MSI Reminds You...
The value plus a ratio (CPU: DDR) with parentheses means the
non-synchronous overclocking.
