Overclocking

We used ATITool to automatically find the maximum clocks of the Twintech 8600 GTS. The overclocking process works as easy as on any other NVIDIA card. There are no distinct values for 2D/3D clocks - the card always runs at 675 MHz / 1000 MHz by default.



The overclocks are very limited. In the end the card runs totally stable at 727 MHz core (7.3%) and 1075 MHz memory (6.6%).



The small stock cooler does a good job at keeping the card cool. It does not get very hot, not even when overclocked. The fan noise is very acceptable for this kind of cooler. What I noticed though is that the fan speed control does not kick in until a driver is loaded, while this is only a minor issue for Windows users it could become a bigger problem for Linux users who rarely use XWindows and the NVIDIA drivers.
