Simple Undervolting Tutorial - Pentium M Dothan - Page 50

post #981 of 1202

I tried reading this huge thread and got through like 40 pages...and then decided to search but still couldn't get an answer. I have a I9300 and i've been trying to undervolt this system. I get all the undervolting correct. currently at a min of .716 and a max of 1.52. Everything in the guide was done correctly. Now here is my question/problem It seems to be locked at 1.86ghz and it doesn't seem to want to throttle down to ~800mhz. Its doing well at 1.86 undervolted and it does fine if i force it at 800mhz undervolted (minimal). But it doesn't seem to want to throttle back down depending on CPU usage like it does normally if its not undervolted when i put it on auto. Anyone with a I9300 or anyone who knows what I'm talking/knows how to fix it please tell me. Other than this little prob this is a great program!

EDIT: upon rereading my post it basically boils down to "How can I make this CPU throttle down undervolted...because its not going back down even if I stick it on Auto-managment; while it works fine when i force it maximum/minimal undervolted.

Makes dure the "on demand clock modulation" is unchecked. and mode is set to "balanced performance/power saving"

yeah its all unchecked. For some reason as i'm booting up i see it throttling ie. the little gear lighting up. Then as soon as i'm done booting i see it solid red, meaning that its totally maxed out on the throttling...

Syan, you set P-State 0 as 6x with your low voltage and P-State 1 as 14x with your 1.52v (probably can go lower btw), right? You have Use OS load-based management checked and run HLT command when OS is idle checked, right? See if those are set first.

omg thanks, i've checked the os thingy and it works now. How come the guide never said to check that option. As for the run HLT when OS is idle...what does that do and should i check that if I have a I9300?

Mine did not need to be checked..... Hmmmmm... Why is that?

AFAIK it's checked by default

Hi, I have the following number as default...

startup: 6.0x 0.956v
minimal: 6.0x 0.700v
maximal: 15.0x 1.484v

would you recommend modifying the minimal?

Hi again,

I was having problems with toshiba powersaver and RMclock.

So, I disabled the powersaver, and have been running RMclock with powerprofile "always on". However, i'm still having the random freezing problems... (freezing, sometimes freezing then reboot)

Pent-M: Dothan
Min 6.00@0.732V
Max 14.00@1.132V

what could be the problem? any suggestions?

My friend's Dell 9300 has the same freezing problem, only he is using CHC. How prime95 stable are your voltages? The only other thing I can think of that would help would be uninstalling both RMClock and the toshiba powersaver utility, rebooting, then installing RMCLock again to make sure there are no driver conflicts. Anyway, when I have a look at my friend's laptop within the next two weeks I'll post any findings.

well, it ran 12h straight w/o errors... (w/ toshiba powersaver disabled)...then i tried again, (powersaver enabled) and it froze before the 12h mark (sometime while i was sleeping)...

i'm so confused....

Yeah, copy and paste from the first page?

I think the best stress testing out there is HL2 or Counter-Strike Source. I've run prime95 for 24 hours straight + superpi (32 million digits) for 6 hours and everything was stable.

Then I started CS:S and my comp restarted... wow

the best is to run Prime95 until it appears its stable then run as many apps as you can WHILE RUNNING Prime95 - a super load if you will... i run all the apps i normally run so i know if it passes this its not gonna die on me... i have to have it super stable... i'm not a gamer so i don't care about that but i use mine for work so i can't afford it to crash...

Prime95 plus RMClock, I9KFanGui, PC-cillin, Spyware Dr, MS AntiSpyware, IE, FireFox, Win Explorer, Outlook, Word, Excel, Access, Photoshop, Image Ready, Illustrator, Painter IX, Dreamweaver MX, Flash MX, etc.

I agree, the source engine is incredible when it comes to testing your stability, I usually bump my voltage up a notch after prime95 testing just because I usually crash every now and then too. And I agree with Dozzit, running prime95 while normally operating on your comp (even playing CS:S ) is the best way to stress test.

For months I ignored this, but if there were any problems they would had been reported here.

Testing... but here is my first question (I didn't find on the last 66 pages I've just read :P): does it matter to test using a notebook cooler? Is it better to test without it (can heat change the results?) ?

Thanks. No wonder why this thread is so huge and viewed...

Well, the whole idea behind undervolting is to drastically reduce the temps of your CPU so that you dont need any extra cooling. Having a notebook cooler won't effect the how low you can go with the voltage, but it will effect the temps of your CPU (obviously).

yes, that's what i thought. just to confirm, heheh...

thanks a lot. more than 6 hours and is still fine at 1.052V (17x). Lots of different settings on Prime95. I will let it running until morning (it's almost 2 AM now). Anyway, if it goes fine, I will add one point (1.068, IIRC).

Later tonight I will test the minimal (6x) to see how it performs.

One more question: does it matter to stop the test and restart later? Is 2 hours testing + 1 hour of rest + 2 hours testing the same of 4 hours testing straight?

Thanks again!

Yes it does. Stopping the test is almost like restarting it from scratch because the CPU isn't under stress for a bit. It must remain constant. You can still use your laptop as normal while it's testing, just make sure the test runs for at least 10 hrs.

ok, just an update on the freezing issue...

upped my voltages again!

6.0x min @ 0.748
14x max @ 1.164...

i prime95 tested both my voltages 13h each with some surfing, and movie watching... no problems. (with toshibapowersaver enabled) ??

then went to use the laptop to do some web surfing...froze withink 30min.

what the heck!? i'm really getting fustrated.
