RightMark (CPU undervolting and throttling)


Undervolting - Using less power to power the CPU, usually less than manufacturer recommended or factory set and results in cooler CPU due to lower speeds and less electricity heat. Also results in damaged (slight chance) or unstable (more chance) system if done highly incorrectly.

Throttling - Not quite sure, dam why did I mention this one now i look like a moron IT student.

I do not recommend doing this if you've never thought about needing it cause you don't then!
I will also not post anything up about how to do it but now you know its call undervolting and cpu throttling and the name of RightMark software your free to Google it yourself. But due to my inexperience and high liabality I am not doing anything on this subject as of now.

I've tried to use RightMark(RM) to cool my CPU down on my laptop and it worked it was cooler as when the laptop was idle it used less power. But when I switch off RM or reverted back from Power On Performance to Vista controlled power settings I'd get a crash dump and BSOD.

Current success:

  • Fail, unless using on battery and I really needed the extra life I wouldn't use the it.

  • If your doing multimedia it can take a little while to respond and make jitters due ot constant fluctuations in CPU power? (normal as powering up back to full speed takes some sort of time frame) but launching programs aren't affected greatly by the half a second delay.
  • The profile settings made are forgotten after RM is closed.

  • AND of course it crashes my computer unless i have it on Power On Demand all the time until I shut the laptop down, which is what you'd do when running on batteries. But you would still have to deal with only launching the program when running on batteries.

  • It doesn't have a formal uninstall process. You should run the ?????wipeout.reg file to remove any reg files still installed and then just simply delete whole folder.

Reasons against (success result):
  • It has a really nice system status bar icons, showing Temp, CPU frequency, CPU load. But the general GUI interface is confusing for a non-undervolter user.
