What is the exact use of RMClock utility ?

Is it used for monitering or some tweaking as well ?

What is undervolting ?

Does it affect my battery life/performance in any way ?

Any help will be repped [does anybody even care abt this....ha !!]

 

1.) Yes, and yes.
2.) Undervolting.
3.) It can affect battery life, but should not affect performance it if it's done correctly.

Your computer will not benefit very well from it because the lowest multiplier is already locked. It worked better on Pentium-Ms.

 

thanks...

Can u pls elaborate on ur third answer ? Why can't I benefit ?

Btw as promised repped +

 

I don't see how it cant benefit him. He can undervolt the cpu (even if the multi is locked) and have the cpu use less power and run cooler. Cooler temps mean more battery life, less fan noise and more life out of the cpu.

 

"Wreck" as in permanently wreck or brick it? Or just screw it up to the point of having to reinstall the OS or something equally benign?

You cannot wreck a cpu by undervolting...

The worst that can happen when you undervolt too much is cause a system crash and instability. But you can't hurt it. If u give it too much voltage, it will fry and be dead, but if u give it too little voltage it's not gonna die. It's just not gonna work untill you give it enough volts.

 

Because the lowest multiplier is locked, he cannot go below that voltage (0.95V, I believe) The obvious benefit to undervolting is lower temps and longer battery life. Because a laptop usually is running on its lowest multiplier when unplugged for maximum battery life, there is no gain. The only place you'd see a gain is if you are able to undervolt while running off an outlet. This will give you a little lower temperature, but no battery saving. I didn't say it couldn't benefit him, I only said that it won't be as nice as some other chips that didn't have a locked lower multiplier.

 

Thanks for the links....very informative

I think adinu in right.....undervolting may not 'wreck' ur notebook...!!

 

Right, 'wrecked' was the wrong phrase, 'crash' is the better word.
Sorry if I scared anyone, not intended. English isn't my native language.
Will choose more appropriate terms in the future.

 

Yup, so to summarize what RMClock can do for you:

It can lower temps and fan noise while plugged in. But it won't extend your battery life.

But all of this at the cost of system crashes and instability if done wrong.

 

Done wrong is avoided through testing. I haven't read the guide, which may already cover it, but I find one Vcore increment above a 12 hour stable load voltage, such as with CPUBurn, will leave you BSoD free, permanently.

That it won't extend battery life is true only in one sense: You won't get any more battery life than what is able to be achieved with the CPU kept in its lowest P state. However, focusing on this truth ignores an advantage - Having extended battery life in higher P states. My Pentium M 1.8 GHz Dothan Dell Latitude D400 chews up about 17 watts at its lowest P state while running CPU Burn. Using RMClock I can run the CPU undervolted at 1.4 GHz while running CPU Burn and consume only 2 more watts. Since RMClock lets us tune Vcore for each multiplier and decide which mulipliers run we can set our CPU's to run at ULV power levels - achieving ULV performance and battery life without an ULV CPU.

While a cool and quiet laptop may seem trivial, I wouldn't put up with anything less. So much so, that my laptop runs speed-stepped by RMClock between .6 GHz @ .716 Vcore and 1.4 GHz @ .908 Vcore, both on AC and battery. I never hear my fan and the laptop is very cool.
