I'm not the expert on RM Clock but I run it. Yes, v.1.7 is the latest and the config has changed slightly. THIS post gives updates for v.1.6, which apply to 1.7 also. In the Management tab you only need your MIN and MAX states defined, "as long as" you go into the Modify button on each and check "Auto-adjust intermediate ... VIDs". My states for my 8104 are "P-State 0, 6.0x, 0.700V" and P-State 1, 15.0x, 1.100V. If you don't want to do all the Prime95 tests find some successful examples for your computer within this thread and use those. If they don't work then adjust them, as results may vary even on the same model laptops. I tried CHC (Centrino Hardware Control utility) for awhile but my lappie seemed to run hotter. Good luck.

I have been using this for a while, and my temps have decreased so the fans rarely run

Thanks! I'll check it out and start testing!

Hi,

I am using CHC and it works greatly.... my idle temp has decreased from 51-52º to 48º, and fully load temp has dropped even more. My fans did not work too much before undervolting, but now my laptop feels much better and cooler and it will never go above 56º any more (before it used to work around 64 under light load -> word processing, surfing and emule). Great thing, undervolting!!!

I know that I could decrease my temp using good thermal paste, but I do not want to open my lappy.... still have the warranty and dont want to void it

That's why undervolting is great for everyone, glad it worked out for you. I did some testing and CHC gives me the same temps as RMClock, but I'd imagine each laptop has the possibility of handling the programs and undervolting differently.

hi all, gonna try this tonight on my FS 3438g. one question: whilst running prime95 for those few hours to check for stability, should i leave the computer alone or can i use it as normal (ie. surfing/gaming)? tia!

i use mine as much as i can cause i wanna know it's stable... i just use the torture test to get me close, then when it runs alone ok i start running stuff with it and really put a load on it... i then move it up one notch for my peace of mind... this is how i make my living and i'm not takin' a chance on losin' data... it's worked so far :-)

thanks for the reply. im actually running it now and it seems to be running fine at 0.700v and 1.036v (crashed my computer at 1.004v and caused errors loading firefox at 1.020v). im not too sure how much benefit its doing though as im not sure what the temp was prior to undervolting... whats the best way to measure the temp - is there a nice piece of free software i can use that wont bloat up my system? thanks again

Centrino Hardware Control (CHC) Link is a program that I and many others use to undervolt. The process is the same as RMClock, but the user interface is simpler. The program also gives temp readouts, which is very convienent

thanks for that! much nicer interface on CHC - ive now deleted rmclock (disappointed there was no uninstaller...). one last question: is it best to set the cpu to max performance when on AC or is the inbuilt speed adjustment good enough to manage the system in your opinion?

there's no need, only need to uninstall the .exe... there are a few registry entries, but RMClock_WipeOut.reg, included in the zipped pkg should take care of them... i use a registry editor cause i like to know i got 'em all, but there aren't many...

All setting to max performance on A/C does is make the CPU run at it's highest clock all the time. It's kind of a waste, specifically because P-M's are made to be able to downclock. Why heat up your laptop a little more if you don't have to?

I've found setting my CPU to max does give better performance, even though the CPU is supposed to automatically clock up if needed.

And undervolting makes it a nice temp

true i suppose . just to let you know i ran tests on max 1.036v overnight (6hrs) and had no errors and im running same test again all day today whilst im at work just to be safe. temps seem to be around 53C (ish) whilst testing. not sure what it was before but its got to be better than it was, surely! finally thank you so much for this tutorial K6 its much appreciated by all and thanks to everyone whos helping others by answering questions

since i prefer RMClock to CHC, i use I9KFanGUI for temp control... great utility, more sophisticated than CHC and a cool web site too lol
