please help me on this issue (throttlestop)

I am a bit confused on the similarities and difference between RMClock and Throttlestop.
I use RMClock on my T60p to undervolt the CPU. I heard that undervolting is not applicable to core i5 CPU, right? So does throttlestop do the opposite by having the CPU running at the maximum speed? If I don't do anything intensive on the X220, just want to keep CPU cool, is there a program for that?

 

Have you tried Lenovo Power Manager?

 

yeah, i am just very curious why Throttlestop is so popular, it seems goes against making laptop cool

 

I don't understand how you see ThrottleStop was intended on making your laptop cooler? It's as the name sounds, it stops throttling. It is for notebooks that already have a good cooling system, and unleashes extreme edition CPU's.

Unfortunately there is no way to undervolt Core i series CPU's to the extent of RMClock as Intel completely changed power settings for the CPU's. Might as well wait for Ivy Bridge as 3D/tri-gate transistors are fully implemented.

 

Okay, the sandy bridge does run cooler than the Merom on my T60p, I am fine now.

 

What throttlestop does allow you to do, however, is disabling Turbo-boost. This prevents the chip from being OC automatically, and keeps it about 10 degree cooler. I always use it to keep laptop temp in check while I game.

You can also limit the multiplier down as much as you'd like. Higher multiplier requires higher voltages, so by limiting the multiplier, you're essentially putting a ceiling on how high the voltage can go.

It's a very powerful tool, and always part of my list of essential program to install on a Core i5/i7 laptop. (It goes without saying that this is not a tool for novice users, of course. You have to know what you're doing if you don't want to mess up your system.)
