Asus P6TD - Deluxe Motherboard - ATX - 3.4.5 DRAM Frequency; 3.4.6 UCLK Frequency; 3.4.7 QPI Link Data Rate; 3.4.8 DRAM Timing Control

3-16 Chapter 3: BIOS setup
3.4.5 DRAM Frequency [Auto]
Allows you to set the DDR3 operating frequency.
Conguration options: [Auto] [DDR3-800MHz] [DDR3-1066MHz] [DDR3-1333MHz]
[DDR3-1600MHz] [DDR3-1866MHz] [DDR3-2133MHz]
The DRAM Frequency conguration options vary with the BCLK Frequency
item settings.
Selecting a very high DRAM frequency may cause the system to become
unstable! If this happens, revert to the default setting.
3.4.6 UCLK Frequency [Auto]
Allows you to set the Uncore Clock Ratio. The value must be at least twice as
DRAM frequency. The valid value ranges differently according to your CPU model.
3.4.7 QPI Link Data Rate [Auto]
Allows you to set the data rate of the QuickPath Interconnect (QPI).
Conguration options: [Auto] [4800MT/s] [5866MT/s] [6400MT/s]
3.4.8. DRAM Timing Control [Auto]
The items in this menu allow you to set the DRAM timing control features.
The conguration options for some of the following items vary depending on thedepending on the
DIMMs you install on the motherboard.
