Has anyone here undervolted a Dothan 2.0 yet? If so, what voltage did you use for full speed/downstepped?

As all RADEON is just one choice in the modding process and the X300 is mentioned in the .inf files, I suppose my modded driver will work on your machine

well, upon my experience on ATI sort of drivers.
it seems that it can perform well without using tha catalyst.

what kind of obvious effect you guys observed after using this ATI control panel?

Please share with us, thanks

Got my T43 yesterday.

.7V works for me at the 6x multiplier....wish I could go lower...wish I could do a lot of things though (like dim the screen more)

Anyway, has anyone noticed that the window keeps shrinking on CHC/NHC?

after opening and closing it a few times, I can't click on the tabs any more.

gunston · #187 Post by **gunston** » Sun Nov 13, 2005 12:31 am

that might be the CHC software bugs.

christopher_wolf · #188 Post by **christopher_wolf** » Mon Nov 14, 2005 3:47 pm

That isn't normal...I haven't noticed it, at least.

hootpie · #189 Post by **hootpie** » Thu Nov 17, 2005 3:19 am

I have a T42 2373-M3U and I'm using the current settings:

6x - .716
8x - .748
10x - .828
12x - .892
14x - .988
16x - 1.068
18x - 1.148

My T42 runs a few degrees celsius cooler and battery life increased ~30 minutes. So far after a few hours, it's running just fine. Before, the fan would turn on every so often (it was at the lowest speed), but now it's completely off. I'm hearing another fan-like noise coming from the HD/CD rom area, but its neither the CD-ROM nor the HD.

Edit: The fan comes on at the lowest setting at 42C, which is right about where it was before the undervolt. Post-undervolt, it hovers between 39-41C with Wifi on and simple web browsing.

pae77 · #190 Post by **pae77** » Thu Nov 17, 2005 1:17 pm

Responding to the post directly above, I have selected slightly more conservative settings for the 8x through 18x settings, but a more aggressive setting for the 6x which I set at 0.700. My reasoning is that most of the time I am on AC anyway, so I would rather have a bit more extra margin of safety when the processor is working harder than 6x, and when I am on battery, I force my system to run at 6x where the .700 setting provides the maximum battery life. So far after several weeks, the .700 setting has not caused any problems as far as I can tell.

nrj45 · #191 Post by **nrj45** » Fri Nov 18, 2005 2:56 am

lol... i made exactly the same thing. 800 at 0.700 and all other settings less agressive...

i have to say that i run these settings for about 3 months (and i'm using my laptop in average 9 hours per day). It's stable for ages in prime95 and during these 3 months my t43p never crashed...

My cpu is also a bit cooler but the fan is always on ...

Same here..s.ame specs pretty much but on a T42P...I am really really tempted to stick a freaking resistor inline with the DC power cable supplied to the fan just to shut the [censored] thing up a bit..Jeez...why does it have to run continuously at 37 dec C???

Gawd! Irritating when you are trying to think in a quiet room...

Yeah...resistor the [censored] and extend my warranty to 5 year and if the lappy dies, I replace the fan bit, I am covered...yeah...

christopher_wolf · #193 Post by **christopher_wolf** » Fri Nov 18, 2005 11:38 pm

What?

Runs always at 37C???? That isn't normal...

Related Note: I ran my T43, hooked up to a Projector no less, for one hour today on battery and the fan didn't come on.

pae77 · #194 Post by **pae77** » Sun Nov 20, 2005 4:18 pm

On AC, the fan on mine seems to come on after it has been operating at 42 C for a while and then it shuts off after it cools it down to 39, but not right away. It usually keeps running at 39 for a couple of minutes before the fan shuts off. Then it stays off until it gets back to and has been operating at 42 again for several minutes.

christopher_wolf · #195 Post by **christopher_wolf** » Sun Nov 20, 2005 5:27 pm

That behavior is similar to what I am getting, though mine seems to do it at around 40-42 Degrees and spin for 1.5 minutes afterwards before shutting off. Another thing I have discovered is that, when you plug into AC after the fan comes on while you were on Battery, the Fan instantly spools down to barely audible and even shuts off after awhile.

Cpgeek · #196 Post by **Cpgeek** » Thu Dec 08, 2005 4:34 pm

I have been testing on and off for about 3 days now with Notebook Hardware Control 1.9b03 and prime95 to get these results. I decided to only test for multipliers up to 10 as i told my machine to never go higher than that while running on the battery (most of the time i don't need it). so here's my list for my machine (see my signature)

CPU Voltage
06x - 0.780
07x - 0.796
08x - 0.796
09x - 1.052
10x - 1.116

and i've got my CPU Speed set as:
Dynamic switching (for both AC and DC)
Enable custom dynamic switching
AC Min: 06x, min load 30%, delay 0ms
AC Max: 16x, max load 80%
DC Min: 06x, min load 65%, delay 0ms
DC Max: 10x, max load 90%

if anyone could suggest any further optimizations for me, please fire away

StarTraveller · #197 Post by **StarTraveller** » Thu Dec 22, 2005 3:59 pm

I've been playing with NHC on my T43p with a 2.13 GHz Pentium M. I've only done fairly extensive testing on 3 multiplier levels so far and these are the voltages that appear to be stable:

Code: Select all

 800 MHz  (6x) @ 0.700 V
1466 MHz (11x) @ 0.828 V
2133 MHz (16x) @ 1.084 V

I can run Prime95 without errors for hours at those voltages. It's worth noting that running at full speed with moderate load around 30-50 % used to put me around 70 C with default voltage (1.356 V), but with the reduced voltage of 1.084 V I'm hovering around 55 C. A very nice improvement!

Over the next few weeks I'm going to let my little work horse crunch away at the Prim95 torture test just to be completely sure that the above voltages are okay. It can take a while for an error to manifest, I think, as it took almost 3 hours to produce one with 2133 MHz @ 1.068 V.

I've configured NHC to use the following settings:

Code: Select all

Enable custom dynamic switching
Switch only between min. and max. Multiplier

AC: Min. Multiplier:  6x    Min. Load: 25 %    Delay: 250 ms
    Max. Multiplier: 16x    Max. Load: 80 %
DC: Min. Multiplier:  6x    Min. Load: 45 %    Delay: 250 ms
    Max. Multiplier: 11x    Max. Load: 90 %

This way, I'll have the power when needed and otherwise enjoy the cooler running of 800 MHz @ 0.700 V which puts me in the low 40's C.

For people who want to play with the custom dynamic switching, I think the rule of thumb should be that:

Min. Load < (Max. Load * Min. Speed / Max. Speed)

Otherwise the CPU will just switch back and forth if your applications happen to require exactly the computational power of that middle region...

I set the delay to 250 ms because I only want the CPU to power up if it's really required, e.g. suppose I want to compile the code I'm writing or launching a new program. My preference is that minor temporary increases in CPU load shouldn't affect the CPU speed.

For my "Power User" profile I've downclocked the FireGL V3200 to 300 MHz core and 150 MHz memory (default is 400MHz and 250 MHz, respectively) and for all other purposes I let the ATi PowerPlay do its magic and that takes it down to around 105/125 MHz. I wish I could play with the GPU's voltage too.

jongordo8 · #198 Post by **jongordo8** » Sat Dec 24, 2005 3:40 pm

I have a T40 with the banias 1.3ghz CPU.

Here are my lowest voltages that I can get stable through the built-in full stability check in NHC. (I am actually disappointed, I was hoping to get 6x down to .700)

6x .748V
8x .860V
10x .908V
12x 1.004V
13x 1.100V

I just got the laptop, but putting Artic Silver 5 will help cooling, will it enable me to go lower with the voltages as well? I build desktops, so I know I have extra Arctic Silver laying around, should I take the time to add it?

My temps at 600mhz are usually about 35-38, and are about 55 at full load.

Any advice would be greatly appreciated.

simms · #199 Post by **simms** » Sun Jan 01, 2006 4:49 pm

Thought I would contribute:

I have a T40 2374-PU2 w/ RADEON 7500.

My settings are
6V .764V
8V .780
10 .876
12 .972
14 1.084
15 1.132

All are stable with Prime 95 from 6-12 hours.

Using ATITool, slowest I can go without artifacting the 3D box is
Slow 169.94 / 182.65 (anything lower works, but will freeze the 3d artifacting box.)
And my fastest is 300 / 242.

robo47 · #200 Post by **robo47** » Tue Jan 03, 2006 5:05 pm

Currently testing my 1.73 CPU

800mhz@0.700 is working since one hour on prime, while looking DVD on second monitor. no problems since this time, cpu is running @ 50°C

ATI x300 is @ 65/65, dealing with the tft and a old crt both @ 1024*768@60Hz

i will edit this post when some new data is avaible from testing

hmm it just hang and rebootet, but think it was a error by vlc, will now test @ 0.716 for some hours if it works again a test @ 0.7

6x 800mhz @ 0,716 works

Here's thE data for my sonoma 760 processor (2GHZ)

6x: 0.700
8x: 0.732
9x: 0.764
10x: 0.812
11x: 0.844
12x: 0.892
14x: 0.988
15: 1.036

I added 2 extra voltage steps to all speeds above 6x to give it some margin (as I only tested thouroughly 6x and 15x with prime95, and prime95 only worked stable with mentioned 15x voltage plus 2 steps).

This is partially intended as a reminder to myself should I have to repeat the procedure

Hi,

I see that NHC is using 32Mega Bytes of virtual memory on my system. That is a lot. I want to find an other program that does the same with less memory. Can anyone recommend an alternative software?

I think you're looking at the peak memory usage.

I just took a look at Task Manager and it does list 34 MB as the peak memory usage, but the current memory usage while the application is running and doing its thing is merely 2-4 MB. The peak is obtained over a 10 day period and I don't how often it has reached that amount.

Also of interest is that in 10 days it has only accumulated 23 minutes worth of CPU time (most of that probably at 800 MHz CPU speed). That's quite acceptable in my book.

christopher_wolf · #205 Post by **christopher_wolf** » Mon Jan 16, 2006 5:20 pm

I don't know of a "Same Program" alternative to NHC; but you could take a look at MobileMeter as it does not need the .NET access framework to run.

hi guys!

i use an x40 (dothan 738) and even though i adjusted the 6,8,9,10 to lower values than default, it just doesent pull down the wattage!

i tried a test and with or without NHC battery goes in exactlely amount of time! the progr seems amazing but how can i make use of it!?

thanks alot,

dorin

ps: the fan control goes on X40!!! ideal for AC and i;d love during DC to use NHC to add some life on battery!

Startraveller, I like your idea for the custom dynamic switching. I'm using your settings now.

LRoy · #208 Post by **LRoy** » Mon Jan 23, 2006 6:16 pm

just two more quick data points -

My T42p (Dothian 1800) and R50p (Banias? 1700 I think) are both working with no issues set to 600Mhz @ 0.700v Not extensively tested but both have 30-45 minutes of prime95 and the NHC full test under their belt.

I haven't played with any other speeds yet as I was mostly concerned about reducing noise/heat and extending battery life when off of AC.
