The Matrox Users' Resource Centre has word of the release of a new version 1.12 Beta Build 015 of the MGATweak tweaking program for Matrox cards."The new version improves the overclockability of the G400 MAX by providing clock duty cycle correction control and the option to turn of auto duty cycle correction as used in previous version of MGATweak, at the expense of violating the chip specification PLL programming procedures. Duty cycle correction is further explained in the user guide. By ignoring duty cycle correction, some G400 MAX can go as high as 170/227."
