My t42p 15" is not stable at 600Mhz@0.700V : it often fails to come back from suspend2ram mode -- even if it was rock solid with NHC tests and prime95.

I've noticed that my T43 would occasionally just randomly reboot when running on battery @ 0.700v. I've since increased the voltage to 0.716v and the problem went away. FWIW, I've run my T43 basically 24/7/365 on AC power @ 2.0ghz (1.084v) since July '05 and it's only off maybe a couple hours a week when being transported.

The efficiency of electrical components does decrease ever so slightly over time (capacitors especially) and this may have just been enough to cause the voltage to prematurely drop below 0.700v for the cpu.

What is un-ecological about it? It makes little difference in the end; plus, you have to worry about getting of a very old battery to begin with anyway. Whilst charging, you draw enough to power the Thinkpad and charge the battery; you doun't get something for nothing by charging up the battery and then using it later instead of AC.

Well, it's just that laptops have power off switches... the best undervolting means ever. Then they are really cool & quiet

That might be your take on the situation. However, my puny little T43 did replace a DUAL Athlon MPX machine, with 2GB of ram, 3 15,000rpm SCSI drives, 4-7200rpm SATA drives (now in external enclosures I can turn on as needed) high end Radon graphics, plus a bunch of other crap that I needed running 24/7. That machine easily pulled 600w.

With the display turned off & PowerPlay enabled, my T43 pulls maybe 45w (probably less).

Unecological? You be the judge

Alright guys... does this program have to boot at startup to keep these settings in effect?? If so is there anyway for it to boot, load the settings and then shut off to preserve memory and battery life?

Also, Im checking out my free RAM and I only have about 120 megs when Im just sitting here idling, which is like 21% free, this seems rather low... what are others set at, and is there anything I can do to free up more???

FWIW, my install is rather clean, and I try and keep the registry pretty clean and only booting the essentials through msconfig

JohnT · #218 Post by **JohnT** » Wed Mar 15, 2006 12:05 am

Yes. This program has to run in the background. It actively monitors system load and applies the proper setting accordingly.

Don't get too worried about your ram. windows xp is aggresive on using the ram to speed up the system response.

My computer has been working perfectly since my last fresh install of Windows. Earlier today, I had to restart my computer 2 times because of misc things but everything started up just fine.

After I installed Prime95 and NHC, I followed this threads directions on the process of setting the multiplier/voltage then stress testing with Prime95. Everything was fine until the 2nd test. My system ended up crashing so I let it rest for a second then powered it back on.

Whenever it came back on, I noticed all sorts of problems: wireless not working, bluetooth acting wierd, my virus scanner was disabled, client security services wasn't initializing (couldn't swipe finger to login, only put in password), and many other things.

When looking through my services, I noticed that somehow at least 15 (if not more) services had been disabled (TrendMicro, ThinkPad PM service, TSS Core Services, TVT, Protector Suite Virtual Token, IBM KCU/PSA, etc). I know for a fact all of these services were running just fine before the Prime95/NHC installation.

Luckily a system restore from yesterday got me working just fine but anyone know what may have caused this? I've seen Windows crash a million times but not cause these problems.

It's probably not about number of crashes. It's about when it crashes.

anyone realize that the latest 1.10 beta of Centrino Hardware control is conflicting with the IBM Power Manager?

How so? I haven't seen any problems.

gunston · #223 Post by **gunston** » Wed Apr 12, 2006 7:45 pm

it seems like when you are using CHC 1.10 beta version, you are unable to choose the Scheme option under Power Manager,
each time you reboot your thinkpad, the Scheme option will remain blank/not choosing anything although you have choosen one of the Power Scheme option before rebooting.

That is the same issue i faced. In the end, i let power manager take control.

no undervoltage?

Well I'm currently testing my T41 with it's new Dothan 755 upgrade from the 1.6ghz Banias.

2.0ghz now runs at 1.164v 12h prime stable.
600mhz now runs @ 0.700v 10h prime stable.

Looking good. Full load at 2Ghz hits about 55C (when I replaced the CPU I used AS5) and 600mhz loads at 38C.

Hopefully this should extend my battery life by a fair bit. Almost 3W are saved at 600mhz at that voltage and 2W saved at 2.0Ghz. Very nice. I tried 1.120v at 2ghz but it failed prime after 11minutes so I went up 2 notches to act as a buffer.

Next stop, the ATi Mobility Radeon 7500 32MB

Using NHC, it seems I can go lower 0.9xxx volts on my X60.
How is that possible ?

gunston · #228 Post by **gunston** » Tue May 23, 2006 2:22 am

it is common

thibouille27 · #229 Post by **thibouille27** » Tue May 23, 2006 8:42 am

too bad

gunston · #230 Post by **gunston** » Tue May 23, 2006 8:48 am

don't you feel good of that, since your x60 can undervolt some much which still running at full speed.
in other words, this means less heat is dissipated!!!

thibouille27 · #231 Post by **thibouille27** » Tue May 23, 2006 9:28 am

ouch, a couple characters didn't get into my original post, sorry for that it should have been:
Using NHC, it seems I cannot go lower than 0.9xxx volts on my X60.

I often see people talking about 0.7Volts... For me 0.9 is the minimum

BTW, is 1GHz the minimum frequency for a T2400? no way I could go lower ?

simms · #232 Post by **simms** » Thu Jul 20, 2006 2:14 pm

Are people still reading this thread?

7 0.700
8 0.700
9 0.700
10 0.716
11 0.748
12 0.780
13 0.828
14 0.860
15 0.876
16 0.940
17 0.972

Now my question is, can I always run mine at a minimum 9x? Everything from 7x-9x uses 0.700 so would it use more power at 9x even though the voltage is the same?

Yes, it would use more power

simms · #235 Post by **simms** » Fri Jul 21, 2006 1:21 pm

Now, how come? I mean it's still at 7V... how is the power consumed calculated?

neomuzic · #236 Post by **neomuzic** » Sat Aug 05, 2006 10:02 am

how did you get yours to 600? I can't see less than ~780mhz (6x 0.796)

Thanks!!

does anyone have the best settings i can use for NHC?

Im looking for basically three profiles

1. on AC - full performance, full steam ahead
2. on batter - some performance, but enough to be able to keep me working for at least 2 hours
3. on battery - please god dont let this laptop die, im in the middle of somthing

i have a t42 with 1.8dothan and 1gb ram.

cheers

I've been having this doubt for quite some time:

People who have applied Arctic Silver 5 on the CPU & GPU that report to reduce some degrees off the cores:
Did you use the NHC before and after the AS5 application?

Because I'm still using my Dothan 1.8GHz at full speed, without any utility (like NHC or TP Fan Control) and after applying AS5 I see the same temperatures on both CPU & GPU than before.

My question is:
Fiddling with the correct values on NHC to reduce the voltage on my processor, could it run below the 40C degrees?

Also, NHC allows you to lower the GPU processing power?? (I have POWERPLAY disabled in the Windows ATi Control Panel, but in NHC its grayed out the option to use PowerPlay in NHC)
