nVidia Riva 128

Go to the windows folder and open pstrip.cfg with an texteditor. You can now
find some information of  videocards. Go to the place where the following lines is.

[Riva128+]
;---------------------------------------------nVidia Riva128 plus
MClk=90,110,100

90 is min
110 is max
100 is normal

Then change the midle number to 150.

[Riva128+]
;---------------------------------------------nVidia Riva128 plus
MClk=90,150,100

Then save changes. Now open PowerStrip and go to Advanced options, then go to
"about PowerStrip", and next "performance". Now you notice that this number you
changed is the max memory speed you can set. Then just set new speed. 150 Mhz
doesen't regulary work without a fan but 133 Mhz works fine.
