Micro Star Computer G31M 3-23, BIOS Setup DRAM TWR, Dram Twtr, Dram Trrd, Dram Trtp, SB Voltage

BIOS Setup

DRAM TWR

When the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. Minimum time interval between end of write data burst and the start of a precharge command. Allows sense amplifiers to restore data to cells.

DRAM TWTR

When the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. Minimum time interval between the end of write data burst and the start of a column-read command. It allows I/O gating to overdrive sense amplifiers before read command starts.

DRAM TRRD

When the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. Specifies the active-to-active delay of different banks. Time interval between a read and a precharge command.

DRAM TRTP

When the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. Time interval between a read and a precharge command.

FSB/Memory Ratio

This item will allow you to adjust the FSB/Ratio of the memory.

Adjusted DDR Memory Frequency

It shows the adjusted DDR memory frequency. Read-only.

Auto Disable DIMM/PCI Frequency

When set to [Enabled], the system will remove (turn off) clocks from empty DIMM and PCI slots to minimize the electromagnetic interference (EMI).

Memory Voltage (V)

This item will allow you to adjust the Memory voltage.

SB Voltage

This item will allow you to adjust the South bridge voltage.

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.
