BIOS Setup

ROW to ROW Delay (TRRD)

When the MCT Timing Mode sets to [Manual], the field is adjustable. Specifies

the active-to-active delay of different banks.

ROW Cycle Time (TRC)

When the MCT Timing Mode sets to [Manual], the field is adjustable. The row

cycle time determines the minimum number of clock cycles a memory row takes

to complete a full cycle, from row activation up to the precharging of the active

row.

1T/2T Memory Timing

This field controls the SDRAM command rate. Selecting [1T] makes SDRAM

signal controller to run at 1T (T=clock cycles) rate. Selecting [2T] makes SDRAM

signal controller run at 2T rate.

Adjust DDR Memory Frequency

You can place an artificial memory clock limit on the system. Please note that memory

is prevented from running faster than this frequency.

Adjust PCI-E Frequency

This field allows you to select the PCIE frequency (in MHz).

Auto Disable DIMM/PCI Frequency

This item is used to auto disable the DIMM/PCI slots. When set to [Enabled], the

system will remove (turn off) clocks from empty DIMM/PCI slots to minimize the elec-

tromagnetic interference (EMI).

CPU Voltage

This item allows you to increase the CPU voltage.

Memory Voltage

Adjusting the memory voltage can increase the memory speed.

Spread Spectrum

This setting is used to enable or disable the Spread Spectrum feature. When

overclocking, always set it to [Disabled].

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.
