Biostar Simga-Gate GeForce 7600GS V7603GS-21 Videocard Review

The Sigma-Gate and V-Ranger utilities are not much to look at, but offer better tools to overclock a videocard with than either nVIDIA nTune or RivaTuner! The Sigma-Gate and V-Ranger utilities support traditional videocard overclocking by manipulating the core and memory clock speeds, and also offer up voltage adjustments for each!
... software utilities work with other videocards, however the voltage options are only available when used with the Biostar 7600GS.
... a few more frequency jumps quick brought us to 630 MHz, and then the GPU voltage needed another small bump up. With 1.34V feeding the GeForce 7600GS GPU, PCSTATS was able to overclock it to a maximum speed of 680 MHz.
... was able to push the Samsung GDDR2 was 1752 MHz (at 2.0V)!
