Active to Precharge (Tras)
Set the time from active back to precharge state. Settings: 5T and 6T.
Active to CMD (Trcd)
Set the time from active state to command state. Settings: 2T and 3T.
DRAM Burst Len
This setting allows you to set the size for DRAM Burst-Length. The bigger
the size, the faster the system addresses memory. Settings: 4 and 8.
DRAM Command Rate
This setting controls the DRAM command rate. Selecting 1T allows DRAM
signal controller to run at 1T (T=clock cycles) rate. Selecting 2T makes DRAM
signal controller run at 2T rate. 1T is faster than 2T. Settings: 2T Command
and 1T Command.
CPU Vcore Select
This setting allows you to adjust the CPU core voltage from 1.100V to
1.850V at 0.025 increment. Please note that it may be dangerous to adjust
the Vcore over 10% of original CPU specification. Setting options: Default,
1.100V to 1.850V.
DRAM Voltage
This setting allows you to set the appropriate DRAM voltage. Setting
options: 2.5V, 2.6V, 2.7V and 2.8V.
Spread Spectrum
When the motherboard's clock generator pulses, the extreme values (spikes) of
the pulses creates 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, setting to Enabled for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking
because even a 0.25% jitter can introduce a temporary boost in clockspeed of
25MHz (with a 1GHz CPU) which may just cause your overclocked
processor to lock up.
CPU Clock
This setting specifies the clock frequency of CPU host bus (FSB) and
3-26
