EIST
The Enhanced Intel SpeedStep technology allows you to set the performance level of the microprocessor whether the computer is running on battery or AC power. This field will appear after you installed the CPU which supports speedstep technology.

Turbo Boost
This item will appear when you install a CPU with Intel Turbo Boost technology. This item is used to enable/ disable Intel Turbo Boost technology. It can scale processor frequency higher dynamically when applications demand more perfor- mance and TDP headroom exists. It also can deliver seamless power scalability (Dynamically scale up,
OC Genie Button Operation
This field is used to enable/ disable OC Genie function.
DRAM Frequency
This is used to adjust the memory frequency.
Adjusted DRAM Frequency
It shows the adjusted DRAM frequency.
DRAM Timing Mode
Select whether DRAM timing is controlled by the SPD (Serial Presence Detect) EEPROM on the DRAM module. Setting to [Auto] enables DRAM timings and the following “Advanced DRAM Configuration”
Advanced DRAM Configuration
Press <Enter> to enter the
Command Rate
This setting controls the DRAM command rate.
tCL
This controls the CAS latency, which determines the timing delay (in clock cycles) before SDRAM starts a read command after receiving it.
tRCD
When DRAM is refreshed, both rows and columns are addressed separately. This setup item allows you to determine the timing of the transition from RAS (row address strobe) to CAS (column address strobe). The less the clock cy- cles, the faster the DRAM performance.
tRP
This setting controls the number of cycles for Row Address Strobe (RAS) to be allowed to precharge. If insufficient time is allowed for the RAS to accumulate its charge before DRAM refresh, refreshing may be incomplete and DRAM may fail to retain data. This item applies only when synchronous DRAM is installed in the system.
