To overclock today we are using the Sapphire TriXX tool, version 4.
We achieved some very impressive overclocks from this hardware with the latest version of TRIXX, thanks to the voltage increase options. Without increasing the voltage, the core was limited to around 900mhz.
This overclock, while impressive does cost … with an increase in temperature, fan speed and noise levels. At 900mhz the card could be run at reference voltage settings so none of this applies. But if you want to squeeze everything from the card, the option is there. We like having the choice.
How do these substantial overclocks help with performance?
These increases are very noticeable and position the card above the GTX570, which is a heck of an achievement.
