Hi guys, For those that want to get more than the 200mV offset available through Trixx you can use a simple registry tweak in Windows to obtain more voltage:- Firstly install the Sapphire Trixx utility and open the program. Save an overclock profile whether it be '1' or '2' etc. Run 'regedit' as administrator. Head to 'HKEY_CURRENT_USER' and expand this folder. Scroll down to the 'Software' registry key and expand this folder. Look for the 'Sapphire TRIXX' registry key and expand this folder. Within this you will see a key folder called '1:0:0-1002:67B1-174B:E285' or something similar. You will then see the profile settings that you saved 'ClockQuick1GPU Clock' and 'ClockQuick1VDDC Offset' etc. If you saved the profile as '2' it would say 'ClockQuick2VDDC Offset'. To change the voltage offset higher than +200mV right click on this key and go 'modify'. Click on or choose the 'Decimal' base value as the value to edit with. Enter the amount of voltage offset you wish to use, for instance if you want +300mV type in 300 as your value. Once this is done simply close the registry and reboot. Once you're in windows activate this new voltage offset by clicking on the appropriate profile within Twixx. You then have your desired voltage offset value (Sapphire Trixx will still only show the maximum of +200mV on the overclock tool voltage slider, so confirm the new voltage with GPU-Z etc). Works for me. Don't blow up your GPU and remember, any overclocking voids your warranty. I'm not responsible for the voltage offset you decide to use ! For any voltage values above +200mV offset some serious water cooling is the only safe option for your GPU.
