I am trying to find a way to overclock my old socket 370 Celeron 600MHz. I started by buying some cheap thermal grease from Radioshack, and I took a heatsink from a scrapped Celeron 1.0 GHz and put it on the 600MHz. Modded a 80mm fan for the heat sink to draw heat away. Now the heat sink feels cold, when I take the fan off, it doesn't warm up much.. And windows reads it as 598MHz. It actually is underclocked. With the Micron 133MHz 512 MB RAM. The bios doesn't allow me to change CPU voltages. If I can't change the voltages, is it possible to overclock using stock voltages with just ALOT of cooling? And if so, is it possible for me to download a good program to overclock the CPU for me? I have a old Anaheim3 motherboard.
