DRAM Timing Mode (Auto)
This item enables you to specify the DRAM timing mode to be configured automati-
cally or manually.
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.
Memory CLK (N/A, 533MHz)
This item is used to set the memory clock mode.
CAS Latency (Tcl) (N/A, 8Clk)
This item controls the timing delay (inclockcycles) before the DRAM starts a read
command after receiving it.
RAS/CAS Delay (Trcd) (N/A, 8Clk)
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.
Row Precharge Time (Trp) (N/A, 8Clk)
This item specifies the Row precharge to Active or Auto-Refresh of the same bank.
Min Active RAS (Tras) (N/A, 20 CLK)
This item determins the time RAS takes to read from and write to a memory cell
RAS/RAS Delay (Trrd) (N/A, 4 CLK)
This item specifies the active-to-active delay of different banks.
Row Cycle (Trc) (N/A, 27 CLK)
Use this item to specify the Row Cycle Time.

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/HT Reference Clock (MHz) (200)
Use this item to set the CPU/HT Reference Clock through clock gen.
Auto Detect DIMM/PCI Clk (Enabled)
When this item is enabled, BIOS will disable the clock signal of free DIMM/PCI slots.
Spread Spectrum (Spread All Clocks)
If you enable spread spectrum, it can significantly reduce the EMI (Electro-Magnetic
Interference) generated by the system.
CPU Voltage (Disabled)
This item allows user to adjust CPU voltage when enabled.
