Introduction
============

NVClock is a small program for tweaking nVidia videocards on 
FreeBSD, Linux and Windows. Originally  it was only meant for
overclocking but these days it can do much more. For instance 
it contains hardware monitoring support using which you can view
the temperatures and fanspeeds on cards that support it.

Further it allows tweaking of OpenGL settings using the NV-CONTROL
extension supported by the nVidia Linux/FreeBSD drivers.

Building, installing and using
==============================

First you have to do ./autogen.sh to create the configure script and
other build files.

After running autogen.sh you need to run the configure script to 
generate Makefiles to build NVClock. By default the script tries to
locate GTK / QT and if found it enables building of the GTK / QT GUIs.

If you want to disable them add --disable-gtk / --disable-qt when running
the configure script. Second the QT detection might not work correctly. In
that case you can use the options listed below:
  --with-qtdir=DIR        Qt installation directory default=$QTDIR
  --with-qt-includes=DIR  Directory containing the qt include files
  --with-qt-libraries=DIR Directory containing the qt libraries

Finally the configure script also enables NV-CONTROL support which allows
tweaking of Opengl / Display options when using the Nvidia drivers on FreeBSD
or Linux. If you don't want to enable this you can disable it using:
  --disable-nvcontrol

The NV-CONTROL support requires X, if for some reason the detection of it doesn't
work try to use:
  --x-includes=DIR    X include files are in DIR
  --x-libraries=DIR   X library files are in DIR

Once NVClock is configured run the commands below to compile and install it:
make
make install

Once installed you get upto three binaries: nvclock, nvclock_gtk and nvclock_qt.
The last two are graphical interfaces and don't have any documentation as the
interfaces aren't very difficult to use.

The binary nvclock is the commandline version and it has various options you can
use. A short overview is given below for more information consult the nvclock man
page.

Usage: ./nvclock [options]

    Overclock options:
	-b  --backend backend	Backend to use: coolbits/coolbits2d/coolbits3d/lowlevel (NV3X/NV4X only)
	-m  --memclk speed	Memory speed in MHz
	-n  --nvclk speed	Core speed in MHz
	-r  --reset		Restore the original speeds
	-s  --speeds		Print current speeds in MHz
	-d  --debug		Enable/Disable debug info
    Hardware options:
	-c  --card number	Number of the card to use
	-D  --Debug		Print detailed debug information
	-f  --force		Force support for disbled hardware
	-F  --fanspeed speed    Adjust the fanspeed; speed is a value between 10 and 100, a delta like +10/-10 or 'auto'
	-i  --info		Show detailed card info
	-P  --punit mask	Activate extra pixel pipelines. (NV4X only)
	-Q  --deviceid digit    Adjust the last digit of the pci id.
	-S  --smartdimmer level Adjust brightness of the backlight; level is a value between 15 and 100 or a delta like +10/-10. (NV4X laptops only for now)
	-T  --temperature       Show the GPU temperatures.
	-V  --vunit mask	Activate extra vertex pipelines. (NV4X only)
    NVControl options:
	-a  --assign		Set an option to a value: -a fsaa=4 or -a vibrance[crt-0]
	-q  --query		Get the value for an option: -q fsaa or -q vibrance[crt-0]=63
	-l  --list		Show all available options
	-x  --xdisplay		Choose another X display
    Other options:
	-h  --help		Show this help info
	          
You can use any option you want. You can type -m --m -memclk --memclk= and so on.
Also, you don't have to enter both memory and core speeds.

If you don't have any experience with overclocking, start with adjusting the speeds
in 1 MHz increments*. 

*Not every memory speed can be set. In case of Geforce/2/3/4 cards cards with DDR memory running
at frequencies higher than 300 MHz you might notice that overclocking goes in steps of 6-7 MHz or
sometimes even 13-14MHz. On GeforceFX/Geforce6 cards the situation is normal again.
