MS-7519 Mainboard DIMM1~4 Memory SPD Infromation Press to enter the sub-menu and the following screen appears. DIMM1~4 Memory SPD Infromation These items display the current status of the current DIMM Memory speed information such as memory type, max bandwidth, manufacture, part number, serial number, SDRAM cycle time, DRAM TCL, DRAM TRCD, DRAM TRP, DRAM TRAS, DRAM TRFC, DRAM TWR, DRAM TWTR, DRAM TRRD and DRAM TRTP. They are read only. FSB/DRAM Ratio This item will allow you to adjust the ratio of FSB to memory. Adjusted DRAM Frequency (MHz) It shows the adjusted DDR Memory frequency. Read-only. Auto Disable DRAM /PCI Frequency W hen set to [Enabled], the system will remove (turn off) clocks from empty DIMM and PCI slots to minimize the electromagnetic interference (EMI). CPU Voltage (V) / DRAM Voltage (V) / NB Voltage (V) / VTT FSB Voltage(V) / SB Voltage (V) These items are used to asjust the voltage of CPU, Memory, FSB and chipset. Spread Spectrum W hen the mainboard'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. 3-22

DIMM1~4 Memory SPD Infromation
Press <Enter> to enter the sub-menu and the following screen appears.
DIMM1~4 Memory SPD Infromation
These items display the current status of the current DIMM Memory speed
information such as memory type, max bandwidth, manufacture, part number,
serial number, SDRAM cycle time, DRAM TCL, DRAM TRCD, DRAM TRP, DRAM
TRAS, DRAM TRFC, DRAM TWR, DRAM TWTR, DRAM TRRD and DRAM TRTP.
They are read only.
FSB/DRAM Ratio
This item will allow you to adjust the ratio of FSB to memory.
Adjusted DRAM Frequency (MHz)
It shows the adjusted DDR Memory frequency. Read-only.
Auto Disable DRAM/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).
CPU Voltage (V) / DRAM Voltage (V) / NB Voltage (V) / VTT FSB Voltage(V)
/ SB Voltage (V)
These items are used to asjust the voltage of CPU, Memory, FSB and chipset.
Spread Spectrum
When the mainboard
’
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.
