i first clocked it to the desired speed and left the card control panel up as you can see i used the nvidia overclocking built in with the driver....then opened 3dmark05...yeah i know it goes back to default.

...from ther e reclock the card back to the desired speed test and apply run 3dmark. you will know right off if it is working or not by the frame rate, if it defaulted back esc out and reclock (test and apply) re-run 3dmark. You may have to do this several times but it worked for me

sit back and enjoy the higher scores

. i would say it works about 1/5 or 20% or the time. I think i had my card pushed pretty hard if i bumped it up just 4 more mhz on the core it would reboot the LT.
