Biostar is about to turn the videocard enthusiast market on its head with the release of the Sigma-Gate GeForce 7600GS videocard.
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!
The strength of this videocard is really illustrated by its overclocking ability, and at maximum speeds it often performed 50% faster than stock! This GeForce 7600GS card was often able to beat an ATi Radeon X1950 Pro videocard. Rarely does the software make the videocard, but Biostar has definitely changed the way enthusiasts can overclock. The Sigma-Gate and V-Ranger 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.
... the memory voltage was increased to 1.85V from 1.823V. This change allowed the memory to hit 1650 MHz ... was able to push the Samsung GDDR2 was 1752 MHz (at 2.0V)!
... we should make it clear that overvolting both the GPU and memory is probably going to shorten the lifespan of both components, but by how much just isn't known ...
