I am using an old laptop and doing heavy processing that needs high CPU usage for a long time (~30mins - 2hours).
When the process puts heavy load on CPU for a long time, CPU overheats and computer shuts down.
Process Lasso is a unique new technology that will improve your PC's responsiveness and stability during periods of high CPU load.
Windows, by design, allows programs to monopolize your CPU without restraint -- leading to freezes, hangs, and micro-lags.
Process Tamer is a tiny (140k) and super efficient utility for Microsoft Windows XP/2K/NT/Vista/Win7 that runs in your system tray and constantly monitors the cpu usage of other processes.
Of course the processing speed will slow down proportionally if you limit the CPU usage, but it should be much better than crashing because of heat or (in the worst scenario) having your computer broken with a burned CPU.
Another very convenient way to set the affinity of a certain executable when it launches is to use the start command. Note that the affinity is set by a hexadecimal value, which may require some trial and error.
Check the process in task manager to view the actual affinity outcome!
Please don't touch voltages because this can damage your CPU if it's too high, or cause errors when it's too low.
Frequencies shouldn't be modified either, just the multiplier.
