To enable the overclocking, you should create the following section in the registry:
HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\NVTweak
and introduce a parameter of DWORD type named CoolBits and equal to 3. After that you will get access to "Hardware" properties page in the driver settings. Now you should enable "Allow clock frequency adjustments" to be able to set the frequencies equal to over-nominal values and reboot the system.
That help any?
