Advanced Chipset Features

Here we see 4 categories of advanced control.  Some things of note on this screen:
- System BIOS Cacheable:   [Disabled]
- NVIDIA GPU Ex:   [Enabled]

Lets move to the "System Clocks" section.


System Clocks

- CPU Multiplier:  Here is where you set the multiplier for your specific CPU.  In this case, we're using an E6600 chip which has a stock multiplier of 9.  This is calculated from the Core Speed divided by the Bus Speed.  In this example, the bus speed is effectively 1066MHz.  In actuality, the bus speed is 266MHz quad pumped to 1066MHz so;
2400 / 266 = 9
*Note: All Intel CPU's have a multiplier lock preventing the end user from raising the multiplier with the exception of the "Extreme Edition" CPU's*
- Spread Spectrum Settings:  Disable all spread spectrums.  This will add minor stability to your overclock.

Leave all other setting on this screen at their default setting.  Once you are finished, ESC back to the previous screen and we'll move to the "FSB & Memory Configuration."


FSB & Memory Configuration

- SLI-Ready Memory:  If your memory is equipped with NVIDIA EPP profiles, the motherboard will automatically enable this option.  If you have EPP memory, set this option to: Expert.
- FSB Memory Clock Mode: This option can link the FSB to the memory clock speed.  Normally when overclocking, the FSB is going to be much higher than the memory clock.  By setting this option to "Unlinked" you now have the ability to clock the memory and FSB independently of each other as seen in this example shot above.
- FSB (QDR):  This is where the actual overclocking happens.  QDR stands for quad data rate.  QDR is calculated by multiplying the actual FSB clock speed by 4 (again because the Intel bus is quad pumped).  In this case the QDR is set to 1466, so the actual clock speed is about 366MHz.  366MHz x 9 (the multiplier of the E6600) = 3300MHz or 3.3GHz which is 900MHz over the stock E6600 speed of 2.4GHz!
- MEM (DDR):  This option sets the RAM speed.  In our case, we're using PC2-8500 which is rated at 1066MHz so we set the MEM option to the RAM's rated speed.
Next, select the "Memory Timing Setting" option.


Memory Timing Settings

- Memory Timing Setting:  Set this mode to Expert so that you, the user, has full control over the available timings.
- Timings (CAS, tRCD, tRP, tRAS):  These values are defined by your memory manufacturer using the the following notation: CAS-tRCD-tRP-tRAS, eg: 4-4-4-12.  In our example, the memory is rated at 5-5-5-15 as noted in the picture above.
- Command Per Clock:  Otherwise known as Command (CMD) Rate.  This value is also defined my your memory manufacturer.  In our example, the Crucial PC2-8500 is 2T memory.
-Advanced Memory Settings:  For ease of overclocking, leave all of these values at: Auto
After you're done making changes, press ESC twice; once to bring you back to the "System Clocks" and again to view the "Advanced Chipset Features."  Now select "CPU Configuration" and read on to Page 3.
