Default Re: adjust gpu/memory settings over nvidia-settings...

An excerpt from the 100.14.11 README (, to clarify which GPUs are supported:
Option "Coolbits" "integer"

Enables various unsupported features, such as support for GPU clock manipulation in the NV-CONTROL X extension. This option accepts a bit mask of features to enable.

When "1" (Bit 0) is set in the "Coolbits" option value, the nvidia-settings utility will contain a page labeled "Clock Frequencies" through which clock settings can be manipulated. "Coolbits" is only available on GeForce FX, Quadro FX and newer desktop GPUs. On GeForce FX and newer mobile GPUs, limited clock manipulation support is available when "1" is set in the "Coolbits" option value: clocks can be lowered relative to the default settings; overclocking is not supported due to the thermal constraints of notebook designs.

WARNING: this may cause system damage and void warranties. This utility can run your computer system out of the manufacturer's design specifications, including, but not limited to: higher system voltages, above normal temperatures, excessive frequencies, and changes to BIOS that may corrupt the BIOS. Your computer's operating system may hang and result in data loss or corrupted images. Depending on the manufacturer of your computer system, the computer system, hardware and software warranties may be voided, and you may not receive any further manufacturer support. NVIDIA does not provide customer service support for the Coolbits option. It is for these reasons that absolutely no warranty or guarantee is either express or implied. Before enabling and using, you should determine the suitability of the utility for your intended use, and you shall assume all responsibility in connection therewith.
