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 (400 MHz, N/A)
This item is used to set the memory clock mode.
CAS Latency (Tcl) (6 CLK, N/A)
This item controls the timing delay (inclockcycles) before the DRAM starts a read
command after receiving it.
RAS/CAS Delay (Trcd) (6 CLK, N/A)
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) (6 CLK, N/A)
This item specifies the Row precharge to Active or Auto-Refresh of the same bank.
Min Active RAS (Tras) (15 CLK, N/A)
.
This item determines the time RAS takes to read from and write to a memory cell
RAS/RAS Delay (Trrd) (4 CLK, N/A)
This item specifies the active-to-active delay of different banks.
Row Cycle (Trc) (20 CLK, N/A)
Use this item to specify the Row Cycle Time.

Advanced Clock Calibration (Disabled)
TM
This item can enable greater performance turning margin for the AMD Phenom
Black Edition CPUs. The optimal gain can be seen in configurations that use high-
end CPU cooling solution in combination with elevated CPU core voltage (CPU
" "
VID) value. The motherboards that support advanced Clock Calibration -feature
should enable power delivery capabilities that exceed the 140W CPU TDP specifica-
tions in order to maximize the performance tuning potential.
Auto Detect DIMM/PCI Clk (Enabled)
When this item is enabled, BIOS will disable the clock signal of free DIMM/PCI slots.
CPU/HT Reference Clock (MHz) (200)
Use this item to set the CPU/HT Reference Clock through clock gen.
Spread Spectrum (Disabled)
If you enable spread spectrum, it can significantly reduce the EMI (Electro-Magnetic
Interference) generated by the system.
HT Frequency (Auto)
This item enables users to manually set up the HyperTransport frequency, ranging
from Auto, 1x, to 5x.
