Simple Undervolting Tutorial - Pentium M Dothan - Page 55

My guess is working as designed. Only one P-state deemed necessary for Max Saving or Max Perf, otherwise it's not "max". Same for the drop-down, as the programmer sees fit. Check the discussion thread at RMClock forum here for further info.

Ah, I see. That makes sense now that I actually think about it...I'll look into the details at the link you gave. Thank you for your help!

The final 2.0 version is out on the site now, Im gonna give that a try, you might be interested too

So far, Tecra M3 1.86Ghz:
Max 1.1v
Min 0.716v

(This is with v1.8)

The best thing about the above is not the battery time increase (which is like only 6%, but its free so Im not complaining) but that when the CPU isnt working hard on Minimal, the fans basically never come on. And for the majority who arent aware, this model is particularly loud, so its a big perk.

Hopefully mine doesnt spiral out of control like S_Ninja's, which Im afraid it might since they are both Toshiba's, both the same CPU, and at 0.7v I also get the hard locks he was struggling with.

Edit - Oh yeah, forgot to say, I read the whole mother thread over the last 2 days. The word forums now makes me shudder

Edit 2 - I forgot to mention my only problem. The CPU load indicators are totally messed. Ive tried both having HLT and OS load management on, one off and one on, the other one on and one off, and both off. The results differ, but they are never good. For example, with only OS load management, during load all indicators in RM and even Task Manager show 100%. However, when idling at that setting, Task Manager and RM OS Load show single digit %, whereas CPU Load is shown as 60-70%+ constantly. If I turn on the HLT and turn off the OS load management, during idling RM shows single digit % for CPU Load, and 100% for OS Load, as does task manager, which is correct since the HLT process is taking up that extra "load". However, when I turn on the load with those settings, OS Load in RM and Task Manager continue to say 100% which is fine, but RM CPU Load only hovers around 50-60% rather than maxing out. Im going to try v2 tomorrow, hopefully that will solve this problem, if not then I will be at a real loss.

Just an update. I have sinced raised my voltages according to Mr. K6's advice. Right now I'm running: min: 0.748V, max: 1.164V. I know that these voltages are quite high compared to other undervolters....i guess i'm just unlucky...

It seems to be stable, and I haven't had any hard lockups. I am also using RMclock, and running toshibapowersaver at the same time, so I think that it was never conflicting with rmclock. (it just wasn't apparent by running prime95 tests...)

to make it short: toshibapowersaver does not conflict
with rmclock.

Hi everyone, can I make a free translation of this to portuguese/brazilian? I mean, I i've seen lots of people that are interested on this guide.

obviously, no need to state that credits won't be a problem. it will be a guide based entirely on this, with only a few things added.

the problem is that niddledik does not seem to be active anymore.

Glad you're stable S_NINJA

DDDa, I can't speak for niddledik but if you need to make a translation, I wrote an update for 1.7 awhile back that is along the same lines:
http://www.notebookforums.com/showpo...&postcount=518

Um, isnt the max voltage S_NINJA mentioned WAY over stock? Thats worrying.

And as for the problem I mentioned, I still have it. CPU Usage is still reported wrongly

heh. oops. my max voltage is 1.164V @ 14x. not 1.64. sorry.

Phew, I was worried for a while there!

Well all in all, Ive found that the battery advatange is almost nothing, which is sort of disappointing, as well as rather weird. According to CHC, which I just use as a monitoring app + 2nd opinion, the battery advantage between using 0.988v (or whatever the standard is) and 0.716v is only 1W. Oh well, the lack of fans at idle is definitely still reward enough.

Im still stuck with my completely wrong CPU usage reporting problem, but there doesnt seem to be anything I can do with that, and no one else seems to have the same problem!

Ok Fedor, just read through your post for the third time and figured it out . RMClock shows two loads (as you know) on the monitoring tab. CPU Load is actually CPU load. Windows doesnt show this in task manager (not by default anyway). Any CPU is always going to be loaded, by architecture that's how they run. For instance, Windows keeps the CPU loaded by running the System Idle Process. While the CPU will idle while doing this process, you'll notice that it will take up 100% CPU usage in task manager. However, this does not count as "OS Load," which is the operating system actually requesting the CPU to do work. This kind of work is found in any application that actually uses the CPU and puts it under a load, such as a quick jump to 100% by opening my documents or by staying at 100% playing a game. In short, your settins are perfectly normal. Just make sure that you leave "Run HLT" commands OFF because it just replaces the System Idle Process, which is useless, but do make sure that you leave "Use OS Load" checked. Hope that helped

As I've found lurking in these forums for awhile now, there is nothing but great information and helpful people. Now doesn't that make everyone feel all warm and fuzzy?

Armed with the information in this thread I have (I think!) performed a very successful undervolt on my new D610.

As I write this Prime95 remains stable after several hours at 0.940 at 13x for my 1.73Ghz. Temperature at the stock voltage of 1.356 was 71C, and is now holding steady at 50C. Not bad at all. It runs much cooler, which can only be good for longevity, and it's quiet too. Oh, and it runs fine with 0.7 at 6.0x.

Thanks guys! I shall now let this run overnight and hope for the best!


Jeff.

For what version of RMClock was this guide written? I downloaded RMClock 2.0 and it seems that this version is newer that the one that you've used because the interface doesn't match with your descriptions.

The guide on the first page was done for 1.4 or 1.5. Cant remember exactly right now. There was an updated one later for the 1.8 version, but that also differs from 2.0 quite a bit. The concepts are the same, so I think it should still be helpful in understanding what youre doing, but if you cant, then youll have to wait for someone to make a full guide.

Mr. K6 - So youre saying that my CPU Load being at roughly 60% at _ALL_ times is normal? That really kinda seems weird.

With HLT, both CPU Load and OS Load fall to around 3%, but the problem with that is then it never goes above 60%, even while priming. Also, I did a benchmark with prime with and without HLT, and the one with HLT made it significantly slower. Thus me running without HLT, where the CPU Load is constantly 60% or more. In fact right now its always in the 90%+ range. If I have HLT off, and OS management on, should OS Load and CPU Load basically add up to 100%?

Any of you expirienced problems with the WLAN (intel) after undervolting ???

The first guide was written for v 1.5.

Fedor - Yes, HLT does mess with the CPU, that's why I said leave it off. OS Load is the only thing you should care about, don't pay attention to CPU load (it'll always be around 90%).

And no, no problems with WLAN after undervolting. Are you getting any problems?

And no, no problems with WLAN after undervolting. Are you getting any problems? [/quote]

NO. I was too quick on the "trigger"!!! My problem was not related to the undervolting, but to some old software version not being uninstalled proberly... My new Samsung M70 (Sonoma 1,86 Ghz) is running with min. 0.780 and max. 1.164 without any problems...

OK well ignoring CPU Load, things are fine :P

Thanks for your input and advice!

I was just wondering, I installed RMClock v2.0, and I followed all of the instructions, but is it suppose to run when windows starts or not? When I run RMClock it'll be in the tray along with the FID and voltage and i know its working but when windows starts, the battery will be under rmclock profile but not sure if it's working or not.

Thanks in advance.

how long should you let prime95 run before lowering it again?
