Simple Undervolting Tutorial - Pentium M Dothan - Page 54

PM Banias V. PM Sonoma

Hi experts n this forum. This is my first post here, but I truly read the hole thread (actually I printed it out - it took me my X-mas holiday to read app. 200 Pages). I have a question which some of you maby know the answer to: I have the opportunity to change my 1,7 Banias (400 Mhz 1mb L2) with a LV 1,5 Sonoma (400 Mhz 2mb L2). Besides that I can undervolt the Sonoma ALOT more than the Banias (which I definately will do), which one of them offers me the most "power"???

Thanks in advance

Jakob

BTW. Tried a 2,0 Dothan AND also a 2,1 Dothan in my Mitac 8050d (855 Chipset) and it works fine, allthough I think the fan runs too much in my lappy with these CPU's, so right now I'm stickin' to my Banias (or the LV Sonoma IF if runs as quiet as the Banias)...

I don't think the extra MB of L2 cache outperforms the extra 200MHz that the 1.7 has, so I think the Banias will still be faster.

And wow, someone actually read the whole thread, congrats

my FJ170B benches prime all day long at 0.908V and 13x (1729mhz)



Thank you!

How can I get RMClock to use different P-STates, I dont want to have to choose between minimal and maximal that's kind of lame...

@ Mr. K6,

I have not yet tried to overclock the Banias 1.6GHz CPU in the i855 chipset. The Compaq X1000 was unable to show the CPU temperature in NHC, only shows Hard DD temperature and is 28~32 degC. Is it normal that CPU temperature be not shown on this model with NHC? Or the i855 chipset is handicapped with this CPU temperature monitoring?

why don't you actually go to the RMClock site and learn everything you wanna know? You can actually talk to the creator of it Dmitri Besedin...

Nobody here really wants to hear anything about how something is "lame" when the inquiry is made by someone too damn lazy to search on their own...

btw, what the hell have you contributed in the way of software to the world?

This has been explained about 14 times already, but here it is again: the CPU spends about 0.01% in intermediate states and it is a waste of time and effort to voltage test for each state. However, be my guest, you can set a P-State for each whole multiplier from minimum to maximum if you wish.

Sam- That's extremely odd that there would be no reading at all. Have you tried the older version of NHC, which is CHC beta 2. Also, try e-mailing the creator to see if he has a solution. The program might have difficulty accessing your thermal sensor (maybe it's at a different location than the preset is). I hope that helped, sorry, I'm a little limited when it comes to compaq laptops (I've only worked on one ).

I have a Mitac 8050D with 855 Chipset and have the exact same problem - I tried several programs, but they all fail to read the CPU temp. I'm beginning to think that there are some laptop mainboards where the Temp sensor pin is NOT present or removed

It very well could be present that the temp sensor is only read by the chipset and CANNOT be accessed by software. It happens . Can you do the old "yup, it's cooler" touch test to see any difference in cooling?

Nice work basso! Just make sure you test to make sure she's stable.

It's definetly cooler after undervolting - the fan hardly ever comes on when on PSU. Only when Prime95 or a game is running and even then it's coming on after a while. On bettery it NEVER comes on !!! Even when running Prime95 AND Far Cry together, it's still quiet as night. Before undervolting it ran on and off constantly

So I have undervolted, and I'm currently running Prime 95 with i9kfangui monitoring temps. I tried rasing the voltage to see if I could posibly solve some stability problems without having higher temperatures. Well, the lowest voltage I was able to get was 1.116, fans full blast, cpu temp was 37c. I raised it up until i hit 1.148, which ended up droping the temperature to about 35 with fans still full blast. Went into the monitoring section of RightMark, and its telling me that theres only about a 60% load on my cpu and os, causing lower temperatures. Now this is nice to hear that I'm getting lower temperatures, but why is my cpu and os load not maxed out as it should be, or really as it was when the voltage was lower?

Just thought people would be interested to know that RMClock 2.0pre is out: http://forum.rightmark.org/topic.cgi?id=6:450

Be ready for a lot of changes in how it looks and operates...

Thanks to Needledik

I am a late entrant to this forum and I tried undervolting only today. My results for 9300 1733 Mhz are:
Max Setting 1.052V (13x) CPU Temp: 49 Deg C
Min Setting 0.7V (6x) CPU Temp 44 Deg C

Will it have conflicts running with NHC 1.9Beta03?

Most likely. It's one or the other.

The new RMClock supports different profiles for AC and battery modes, which is perhaps the most important change for users of the previous version. By different profiles I mean setting totally different set of P-States and voltages, not just defining Maximum Power Saving for battery mode.

I'm a little confused as to how to set the previously determined voltages for the min and max multipliers. Do we need an updated tutorial for ver 2.0?
Any help would be most appreciated.

Thanks,
John

In the tree on the left select Performance on Demand, on the right select whatever tab is appropriate (AC Power or Battery), check Use P-State Transitions checkbox, in the list right-click and select Add. Select multiplier and voltage. Repeat Add as necessary. If you want to add more than min and max, uncheck Auto-adjust Intermediate P-States in the popup dialog for subsequent Adds. Select Balanced (or whatever you need) in Performance/Power Saving Preference drop-down. It's pretty intuitive...

Thanks much, that did the trick.

John, not very intuitive

Hm, for some reason it seems I can't add more than one P-state to any other management profile other than the Performance on Demand one. The Performance/Power Saving Preference drop-down box is also grayed-out on all other profiles as well. Is anyone else having this problem or know what the deal is??
