I want to use MCLK.exe to overclock my Hercules S3 Virge DX with 35 Nanosec memory. It runs at 60mhz by default. As you see on the picture I need to fill in several parameters. I have really no idea what figures and/or letters I should fill in to overclock the card to e.g. 80 MHz.
Does anybody know?

At last I found out how it works. You can choose any figure when 1<M<127, 1<N<31 and 0<R<3. When you make e.g. the next command line: mclk /0 117 8 1, you get a 85 MHz frequency.
