Whitewind, Yes, a similar thing can be done. I assume you have the Athlon 64 processor. Check this link out. http://notebookforums.com/showthread...e+crystalcpuid

It works very well. The Athlon will never have the battery life of a Dothan, but it can get close. Using the program CrystalCPUID, I can bring my votage down to .800v which, you willnotice is darned close to where these Intel boys are getting their CPUs.

AMD mobile CPUs will still require more power than Intel mobile CPUs because their (AMD) wattage consumption is much higher.

By undervolting the CPU I have increased my laptop's battery life by between 15 to 25 minutes on average (your mileage may vary). I find the greatest benefit to be the reduced fan usage and corresponding reduction in operating noise.

inotocracy: Reducing the voltage does not have any effect on performance because the CPU is still operating at the same speed, just reduced voltage.

Whitewind: I don't have an AMD system to test this but based on what I've read it should work.

Kenshino: Sorry, I don't have a Compaq so I can't help you.

Med62987: Are you attempting this on your Dell i6000? Do you have any other processor speed/voltage/etc adjustment software (Speedswitch XP, for instance) running?

Yeah it's on my i6000. The only thing I have running is fanGUI. Should i turn it off and try?

I would try disabling it and any other processor/fan/voltage adjusting tweaks.

Kenshino: Did you try enabling or disabling "Run HLT command when the system is idle?" This affects how CPU and OS load is calculated/shown.

I am experiencing the same bug.

Yup, tried enabling and disabling, disabling it made the load drop to 50+%, enabling it made it rise up to 60%. However, Windows Task Manager reports it as 100% all the time.

As a side note, I'm experiencing the display bug too

Okay, I tried. It still does the same thing. . Anything else that could be wrong? Maybe I shouldn't check "Run HLT command when the system is idle"?

im way too lazy to read 20 steps let alone carry out 20 steps. but looks like a good post!

Kenshino,

Is the max VID being reported correctly on the management tab, but incorrect max VID on the general tab? That is what I am expeirencing. What's really strange is it wasn't doing this at first, but started some time after I got it all set up and applied Auto Management. It may have been after I changed the power scheme under windows.(RMClock states you should set it to desktop or always on) But even though it states the incorrect max VID under the general tab, it still tops out at what I have set it to (.998V, the factory low). So maybe this is just a bug in the display. The pop-up balloon also reports my max VID setting correctly.(.988)

Also worthy of note, is that RmClock is now only displaying about 50% CPU and OS Loads. This is under the General Tab if the program. This is while running prime 95 torture test. It had been correctly reporting 100% previously. Perhaps the two are problems related? Of note is that the tray icon sometimes reports a more realistic CPU load via its red graphical display.
(edit: I just realized the icon's graphical display is based on the FID, it seems it has nothing to do with CPU load)

These appear to me to be bugs in the way the program is reporting info, but not the way it is actually managing. But it is harder to actually tell about the actual CPU load than it is the Max VID. The fan runs less and it feels cooler than before. But is this just from the lower voltage, or is it never getting loaded to 100%?

This is my initial findings on my 1.6 Fujitsu S6231.
Anyone else find any strange behavior? Please post any abnormalities.

Man I did this and I colded out my chip. It went frozen and now it wont boot.

Any suggestions?

Since this is done in software it shouldnt be permanant, once you power off your comp it should go back to the regular voltage. Try taking out the battery and ac for a few minutes and try again.

lol that was a joke

never mind!!!

P.S. frozen = ice not system hang

Okily, didnt catch that one

Damn! Nice post!! This is exactly what I need! Setting values now. I tried this before but could never get those settings to take effect - was missing the HLT step! Thanks!!

Awesome! Gonna try this.

God knows I don't even need the 600mhz of throttled power most of the time.
