Simple Undervolting Tutorial - Pentium M Dothan - Page 6

post #101 of 1202

Maybe I spoke too soon, got an error in Prime95 after 12 hours. (Previously I only tested for 7 then interrupted it.) In some respect I don't care, because I will seldom be pushing the CPU that hard for a continuous 12 hours.

Hm, after Prime95 quit, my normal power settings kicked in and the system eventually went on standby. When I woke it up again just now, the fan started up at 4000rpm and it's staying there. Maybe it's just this crappy Asus BIOS, but it didn't do that on a wakeup before I did this rmclock thing.

I'm interested to understand what the rest of the options are on the Management Tab.
For example, I don't understand about the ODCM, unless that's for getting CPUs to behave like the Pentium M's thorttling thing.
Am I right on this? (This would mean that it wouldn't pertain to my Dothan, correct?)

Then there's the Performance/Power Preference slider.
What exactly is this thing controlling?
Again, is this something that the Pentium M has "built in" to it's technology, or what?

This may be a stupid question but can it be done on a D610? And how do you know if it's something you need done?
Thanks, Jane

Undervolting should be possible with most modern processors. It's not something that needs to be done, but can and probably should be done if you're concerned with your battery runtime or processor temperature.

Okay, I was worried about the temperature of my D610 and the fan. It always runs, but I thought this might help!! Jane

Is there any way to do this WITHOUT running RightMark CPU CLock Utility all the time?
Can't it just set the settings and that's it?

Which ASUS BIOS are you running?

if my laptop is on battery. rmclock only allows the cpu to be at the min fid. is there any way to change this if i wanted to play a game (withont changing my min fid to be the same as my max)

Right click the icon turn off "force minimal on battery"

I still don't quite understand why Intel wouldn't do this from the factory...
If it doesn't affect the cpu in anyway except for benefiting temps and battery why not ship the chips like that? There has to be some reason Intel has those specific voltages.
Please explain

It may not just be the chip. It could be the motherboard, chipset, etc.
That's like asking Ford to test drive every car they make and adjust the shocks for the best performance.

Anothyer example is machining parts in a shop. They work to within a few ten thousandths of an inch for precision parts (for most applications).
Concider the "leaway" of high voltage minimum to be the accepted tolerance of the chip.

Aurora, I was running 207 as loaded by Asus after an RMA motherboard swap. Strangely, this version had the static Centrino logo in the center of the screen on power up. I just now flashed to 208 which has the Centrino logo in the lower right, and the animated Asus logo in the center. I'll take this to a different thread...

No, RMClock must be running so that it can dynamically adjust settings.

What program are you all using to check your cpu temps??

@MrKite: I am using I8kfanGUI 2.2.0 to monitor temps and control fans.

I have had my Latitude D810 for about a month and a half now. I Like it so much, I have another one on order for the wife now.

This thread definitely helped me get RMClock setup - a quick thanks to needledik for that. I really wanted to try it, but didn't really have time to figure out what all the settings were for or which ones I could just ignore.

The only thing different that I did, was checked off the "use alternate cpu load determination method" instead of the other one. It was the only way I could get it to stop showing 100% cpu usage all the time.

I tried speedswitch before RMClock - it really wasn't any better than windows controlling it.
Now I just run fanGUI and RMClock for control of my temps, fans, and the speedstep settings. My laptop is a little more responsive and runs a lot cooler now, even with minimal fan running time.

This is one cool post! Thanks needledik!

I'm still waiting for my new laptop to arrive so am yet to try it out. In the meantime, two questions:

1.) What is the memory hog of RMClock?

2.) Almost everyone who has posted results on this thread have a 855PM chipset. Would it work with a 855GM based system too? Specifically, I want to hear from someone with a Dell Inspiron 700m.

Works great on my new 9300 with vmin of .7 and vmax of 1.02. Temps sit at 105* F (41.5 C) at full load with the fan on low. While idle and surfing I've used 8kfanGUI to set the fan to cool the cpu on low once the temps hit 98* F. Thank you a million needledik that info was invaluable to setting this lappy up like I want it.

One question somwhat related to this topic, what temps would you guys consider to be "low", "normal" and "high" for the Go 6800 GPU?

And to answer Beijing's question: RMClock uses 1338kb of ram according to task manager.

This is pretty cool, with minimal profile I now average around 15.2W on battery, used to be around 18W. This has extended my runtime on one battery to about 3:55. Quite a noticable difference, vs ~3hours or less before.
