I have a geforce 4 mx440 and wish to overclock it. The problem is that when i right click and go to display properties, then advanced, i have no tab for my card. I have no idea why this is because it appeared in 98 ME ( i recently upgraded to XP Pro). I have used 29.42 nvidia drivers and am now using 29.80. Neither makes any difference. Its make by leadtek if its any help??
