Using BIOS
Auto Detect DIMM/PCI Clk (Enabled)
When this item is enabled, BIOS will disable the clock signal of free DIMM/PCI slots.
HT Frequency (Auto)
This item enables users to adjust the HT frequency. The default setting is auto and we
recommend users leave the setting unchanged. Modify it at will may cause the system
to be unstable.
CPU Frequency Ctrl (Enabled)
Use this item to enable or disable CPU frequency control.
Spread Spectrum (Spread All Clocks)
If you enable spread spectrum, it can significantly reduce the EMI (Electro-Magnetic
Interference) generated by the system.
CPU/HT Reference Clock (MHz) (200)
Use this item to set the CPU/HT Reference Clock through clock gen.
Adjust DIMM Voltage (Disabled)
This item allows user to adjust DIMM voltage when enabled.
Adjust CPU Voltage (Disabled)
This item allows user to adjust CPU voltage when enabled.
Adjust NB Voltage (Disabled)
This item allows user to adjust NB voltage when enabled.
CAS Latency (Tcl) (N/A, 9Clk)
Memory CLK (N/A, 667MHz)
This item is used to set the memory clock mode.
RAS/CAS Delay (Trcd) (N/A, 9Clk)
This item specifies the Row precharge to Active or Auto-Refresh of the same bank.
Row Precharge Time (Trp) (N/A, 9Clk)
This item controls the timing delay (inclockcycles) before the DRAM starts a read
command after receiving it.
This is the amount of time a CAS is performed after a RAS. The lower the better, but
some DRAM does not support low figures.
Press <Esc> to return to the M.I.B. III (MB Intelligent BIOS III) page.
This item determins the time RAS takes to read from and write to a memory cell
.
Min Active RAS (Tras) (N/A, 24 CLK)
Row Cycle (Trc) (N/A, 33 CLK)
Use this item to specify the Row Cycle Time.
RAS/RAS Delay (Trrd) (N/A, 4 CLK)
This item specifies the active-to-active delay of different banks.
Bank Interleaving (Auto)
This item is used to set the bank interleaving.
Channel Interleaving (XOR of Address bits)
This item is used to set the channel interleaving.
