Someone else has done it to an AS3830TG, but set the multi to 19x, so my AS4830TG should be able to take it. The fun part is the taking it apart. Since I'm going through the problem of replacing the thermal compound, I just as well replace the cpu while I'm at it. I may remove the black paint, since that restricts the heat transfer. My Toshiba has no paint on it's heatsink, and it runs a lot hotter than the Acer does, due to its i7-740QM cpu/Nvidia 350M gpu.
