Simple Undervolting Tutorial - Pentium M Dothan - Page 43

I hope that's all that's wrong. It's probably just the memory though, since the small FFT torture test also puts my CPU at 100% load, but only uses L1 and L2 cache, while the large FFT torture test puts my CPU at 100% load but uses ram in addition to the cache.

Hey, in CHC you can enter multiples and voltages. In the new RMclock 1.7. You click Add and you add your min volt and then go to OK. Then you click Add again and add your max volt. Then you click Add and select a new multiple and it will automactially calculate the correct voltage. Just my 2 cents. Someone test it out. I ented all the Multiples and voltage into my CHC.

Can anyone with a Dell 700m tell me what temps they get?

Hi, i've been reading this thread for a while, and i think i'm read to try this...

just a few questions:

1. I have a Toshiba M40-YP3 with a P-M 1.86.. so when i use rmclock, it takes over the power management right? Will it work alright with the toshiba power managment? (there's a cpu managment setting...)

2. Also, i guess i will be using rmclock ver 1.7... do i follow the 1.6 guide?

3. in rmclock, in battery mode, to get the most time out of your battery, what are the best settings? i don't understand the diff bewteen batt profile and batt. mode...

please let me know.

thanks.

For those with 'pinned' 725's and 735's (400MHz fsb PM), are you able to undervolt much? @ 2.26GHz (735 PM), I get errors @ anything below 1.276v max. I have it set @ 1.292v just in case. I had AOL, and a couple small programs running during the test (already @ 100% load). Could that be an factor?

I have a Sager 4750 with an Athalon 64 +3000 proccessor, what utility can I use to do some undervolting on that? Would it be appropriate to use RightMark on an AMD product?

I'm currently using CHC. I've set my voltages for 6x and 13x only. Do I need to set voltages for multiplers in between? I've noticed the cpu gets throttled to multipliers in-between 6 and 13 with voltages higher than my max.

Ok, lemme see what I can answer here:

Intermediate voltages don't really matter. You can have them if you like, but the way speedstep and Windows XP works is that when your CPU is use it's at 100% and when it's not it's at 0%. I can't think of a process that only uses, say 50% CPU usage all the time, which would warrant an in between step, but why would you want to cut processing power?

I'd recommend disabling any CPU management options because RMClock takes care of all that. I havent had time to fool around with 1.7 and I use CHC myself, but maybe someone who uses 1.7 can help.

Pin-modded processors will always require much more voltage because they are running way past their spec speeds, 33% past to be exact. Just as in any overclocking situation, more voltage is needed to run higher clocks. The fact that you can still undervolt a bit and still be stable is impressive.

I'm not sure if RMClock can be used with other processors. Try it out, the worst that happens is your comp freezes and you reboot. Look around on the site or its forums for more info, but I'd imagine that it wouldnt work well with your AMD64, or at the most it would be very limited in its functions.

As long as the voltages you specified for the high and low multipliers work and stick, then CHC does the rest. What are you using to monitor in between steps, CPU-Z?

I have mine modded to 2.26Ghz and the lowest I was able to go was 1.276V @ max. But it does run nicely at 800Mhx(6X) @ .700V. Running programs while running the test is actually good. It's a true test on your CPU so don't feel too bad about your volts. Mine is right on par with yours.

Well I certainly appreciate the input. It sort of went w/o saying that the stressed CPU would need more juice. With input so far, 1.276v seems to be the threshold. Every little bit helps though...Again, thanks for the input.

here is the link to the RMClock site and the link to the RMClock forum...

should answer all your questions...

in ver 1.7, when you add the min and max you just click "Auto-adjustment intermediate P-State VIDs" and it will interpolate them for you in a linear fashion... you can tune each one if you're really anal retentive but (butt lol) you're really buyin' nothin'...

this isn’t really the case... i leave RMClock on my desktop all the time and it does run at the intermediate steps… unless nothin’ is runnin’ or something is takin’ all your processor, the processor usage goes up and down and works at various steps… it’s kinda like watchin’ a VU meter…

thanks for all the help!

I have finished my testing.

I haven't disabled the toshiba power-managment utill because i still need it to control the brightness for my screen. I did set the cpu control to the highest level, since RMclock takes it over anyways. no problems so far...

here are my numbers for my Toshiba M40-YP3 (1.86Ghz Dothan)

Min. 6.0x @ 0.716V (ran Prime95 for 7.5h @ 0.700V fine.. but when later, i found that my comp froze @ random points)

Max. 14.0x @ 1.100V (works @ 1.085 but i followed K-6's advice and bumped it up for extra stability *and peice of mind*)

right now i'm seeing about 20min of extra battery life, and the fan never comes on @ minimal settings. Undervolting is AWESOME! Unless you are playing games or something, (and you want to overclock), there's really no reason NOT to undervolt! (unless you don't want to put in the time).

for this thread and the threadstarter, and extra thanks to K-6 who upadated the instuctions for RMclock 1.6.

I'm running an Asus Z70V with a Dothan 1.86 GHz. When I run RightMark (or Centrino Hardware Control) and look at my CPU Core Clock at the max. multiplier (14x), it is 1400MHz and not 1860MHz, as I would like it under "max performance". CPU-Z reveals that the FSB is running at 99.8 GHZ and the bus speed is 400 MHZ. I want to be able to put my settings back to 133mhz FSB and 533 Bus. Even without the CPU utilities running, Windows now shows the clock speed as 1.4GHz. I want to go back to 1.86. How do I do this?

Update: All fixed, I just was using a power mode utilizing "degarde" in power management.

Help RM clock (2.13MHz Centrino) Newbie

Hey need some helping setting my correct vid into in RM clock. I have a 2.13 centrino and I have determine my max VID is 1.132. According to this toturial
http://www.notebookforums.com/portal...d.php?t=70943; lines 19 says to go to auto management and put in the max and min VID values.

I am using the 1.7 version of RM and I don't see an option to put in VID values under auto management. How do I put in my values? I also noticed when I select the auto management, my cpu clock goes up to the max, why is this?


Another question

I get a defualt reading req voltage"= ("current" VID .988v), and ("startup" .988v), (min .700v) and (max 1.356v) when first using RM.

When finding my min, am I suppose to start testing from current vid of ".988v" and decrease my vid until I get an error in prime95? I did this and did not receive any error message.



So if this done correctly, is it safe to say my minimal VID is 0.700v and my max is 1.132V

At the top of the management tab, there is a add button, click on that to enter the voltage info, you need to uncheck the auto-adjust check box, then you should be able to enter in the requested voltage level. on the second question, you will need to run an torture test using prime95 for at least 12 hours just to be sure it is ok, if there are no error messages, then you are good to go.

I did run a torture test for a few hours without recieving any error message.

How do I figure out my minum if my defualt startup is "startup.988v"?
Do I need to use .988v as a starting point to decrease the voltage?

highlight P-state 0, clk modify and enter your voltage...

make sure you chk "Auto-adjust intermediate P-state VID's in the "Add/Modify P-State" window so it will automatically interpolate the values between the min and max...

btw, i have the 2.13 and my min is .716 and my max is 1.116 but those are conservative figures so that i never crash... i'm not a gamer i use my xps for work so i can't afford a crash...

i run the torture test overnight and if there are not probs i then keep it running AND run regular apps to make sure i've really pushed it then i move the voltages up a notch so i'm certain that it will never crash no matter how much of a load i put on it...

moving up a notch or two in RMClock is such a tiny voltage increase i think it's more than worth the insurance it gives in return...

then after your min and max are stable, chg "AC Profile" or "Batt Profile" to Automatic Management and the AC/Batt Mode to whatever you want...

also remember that the voltages can differ even for the same model cpu...

opps forgot this...

start at .700, most Pent M's can run at that and it's the lowest voltage they can will run at so you can't go lower...

I guess I'm all confused with all the instructions that I've read in the past few days . While I've figured my max and min voltage (1.132 and .732 respectively--I want to be a bit conservative to prevent a system crash), it seems my CPU clock speed shoots up significantly once I select "automatic management" under Performance Profile. Is this normal or does it level off eventually and I should not worry about it?

I'm not sure anymore if I'm doing things right so if there's anyone out there who can clarify the steps to follow after determining the min and max voltages, it'd be a great help. I'm not sure either if the steps differ depending on what version of RM Clock I'm using. It appears that way to me since there are some buttons/sections I can't find, like the "miscellaneous section" that step 20 refers to on the instructions found here:

Thanks in advance to anyone who can help.
