Configuring the BIOS
43
When the Memory Timings sets to [Manual], the field is
adjustable. Specifies the refresh rate of the DIMM
requiring the most frequent refresh.
1T/ 2T Memory Timing
This item controls the SDRAM command rate. Select [1T]
makes SDRAM signal controller to run at 1T (T=clock
cycles) rate. Selecting [2T] makes SDRAM signal
controller run at 2T rate.
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values
(spikes) of the pulses create EMI (Electromagnetic Interference). The
Spread Spectrum 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, set to Enabled 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.
1. 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, select the value of Spread Spectrum for EMI reduction.
2. The greater the Spread Spectrum value is, the greater the EMI is
reduced, and the system will become less stable. For the most
suitable Spread Spectrum value, please consult your local EMI
regulation.
3. 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.
