Go to NVIDIA nTune to incrementally adjust and test the CPU HTT bus in
Windows. Increasing the
Reference clock (HTT)
to 281 MHz provides a
stable setting that effectively increases the CPU HyperTransport speed by
40% to 1.4 GHz, up from 1 GHz. (Check in using the NVIDIA nTune
Motherboard Settings
control panel shown in Figure 9).
The CPU HTT interface of NVIDIA nForce 590 SLI motherboards can
support much higher speeds. Adjusting the voltage can help you reach
increases of 50 to 60%.
You can achieve more overclocking by using better cooling systems or by
incrementing voltages slightly (both through the BIOS settings and nTune).
Remember that ASIC and board process variation affects the overclockability
of a system.

Run a Stability Test or another application (for example, 3DMark or Serious
Sam) to test system stability.
