The "Undervolting" Guide

well first undervolting does not affect the gpu (well it may go down a degree or two because the whole computer is cooler in general)

my cpu runs at around 22-27 idle and around 38 under full load after undervolting; dont remember what it was before but i think it was around 35 idle and 50 load.

 

and if the heat sinks are connected or the chips are close enough, one chip's temp may affect the other.

before undervolting i took note that my gpu temps were higher than they are after undervolting....

this is during idle.

 

Well I gave this a try and i got my BSOD after reducing my 9x Multiplier (Highest) to 1V, and even then I only got a 2degree drop in Temp (50 deg instead of 52), so I am not sure I am going to bother.

Is it worth keeping RMClock installed to use for CPU Management?

Can I set it up to run slow when idle / not intensive CPU usage & fast when necessary? If so, what is the best settings?

Or is Intel Speedstep good enough at that on its own?

Thanks

Hi all,

Just undervolted yesterday. Running a gateway 6860 with stock processor t5550. Prior to undervolting temp was 79/78. After undervolting to 1.00 for the 11 multiplier, temps are now down to 65/64. However, I notice that the fans are always on now it seems. The don't blow hard, but it's like they're always on. I didn't notice that before. Just though it odd in light of the low temps. At idle the temps are 45/42.

 

even 2 deg. C is going to make a difference for the health of your hardware, but you may want to experiment some more to see how far you can take rmclock.

i don't know what others do with their notebooks, i assume most leave it flat on a table or something, but i prop the back of mine up at an angle (on an XT-stand), so the intakes (underneath) get plenty of cool air.

i have yet to see a BSOD even with the lowest settings on all multipliers, but i did exhibit some freezing with itunes leading to OS lockup.

so far my temps are a steady 4-6 deg C below what they'd normally be without rmclock. safe to say that i'd be using rmclock on all my machines just to reduce energy draw. pc's can draw just as much power as a large lcd or plasma....ouch.

 

Either you have one hell of a cooling system or the sensors for the cpu temp.
aren't being read correctly. What make and model notebook do you have?
I might want one depending on your answer.

 

hi all, i just tried to undervolt my AMD's new turion x2 ultra
but rmclock doesn't detect my cpu, what should i do? as i seriously need to undervolt it, temp. at idle is 65c and underload near around 80c

 

Do you mean you tried to undervolt and it didn't work? Or are you bothered by RMC not listing your CPU? It can often work and still read unknown cpu.

 

it doesn't read my cpu, hence i can't undervolt. what should i do now? i badly need to undervolt my cpu.

 

There is another undervolting program but I can't think of the name ATM. Don't know if it will work either. While you are searching I will keep thinking. It may come to me.

 

So, you mean to say, in RM Clock, under CPU info, it says unknown in the CPU model? Or does it say the CPU core is unknown? You can still undervolt if it can detect the parts that you need for undervolting, like the multipliers and voltages.

 

it doesn't detect anything, that's why i'm unable to undervolt.

 

yeah i wouldnt bother, you CPU seems to be as cool as it is.

though you will get abit more battery life. Up to you if you wanna experiment.

RMclock doesnt touch the fan controls. Your BIOS fan algorithms must be programmed a certain way when it hits 65/64c

Im afraid the latest AMD chips arent supported by RMclock

 

flipfire....r u in touch with the developer, do you think there will be a new release to rmclock any time soon ? perhaps along the lines of improving stability in vista x64 & improved compatibility with the os and other software ?

 

The developers of RMclock (Russian) have ceased future updates AFAIK. You can try the RMclock forums or directly email Dmitri Besedin [email protected].

The new NHC (notebook hardware control) should come out soon. This program will be able to undervolt plus alot of other cool features.

 

AMAZING
I just cut down my temp to 48-51, CPU=full load!
Thank you soooooo much

 

I haven't seen NHC's website updated in years, is this true?


Also, does RMclock work for montevina P8400? I've read a few posts here that say it can. An admin posted that it can not. I don't know what is what now. I'm only interested in underclocking, not undervolting. My issue has never been battery life... all my laptops (except an inspiron 600m) seem to develop massive overheating problems after a year and a half, and knocking down the speed when I don't have a cooler fan is the only thing I could do.

 

No problems. Enjoy

Yes its true. See here

Yes it will work, but it will downclock by 100mhz~ because RMclock cannot recognize half-multipliers. (The P8400 has a 8.5x multiplier, it will be recognized as 8x)

It develops massive overheating problems after a year and a half maybe because the fans are clogged with dust. You might want to look into that.

Undervolting is better than underclocking..

 

i just noticed that when using battery power, my max voltage used becomes 1.250V (the stock voltage) instead of the lower voltage (1.050V) i set up. whats up with that? I thought the settings applied in RMClock profiles applied to both AC power and battery power.

 

Only if you set them both. There are 2 settings, AC and Batt.

 

will the Norebook Hardware Controller support half multipliers? Will it work as good/ better than rmclock?

thanks

 

Hey bro,

Does this guy have a web site I can bookmark so I can check up to see when he releases this software?

 

i believe this is it
http://www.pbus-167.com/

 

Is it possible to run RMClock, but not have it actually do anything to your CPU?

I like having the Processor Running speed & Temp displayed in my system tray, and RMClock seems to do this, using relitavely low resources?

 

You have to set it up for both. RMclock is very customisable you see..

Well the devloper stated that it will fully support the newest CPU's so i assume it will.

NHC is alot of cool features for other parts of your notebook. If you have XP, you should try out the current version. RMclock is more of a dedicated CPU tool, it has alot more advanced cpu tweaks that NHC cannot do .

The NHC website would be your best bet. Im sure NBR will recieve news ASAP anyway. http://www.pbus-167.com/

Yes of course. Its a great utility to have even if you dont undervolt.

RMclock only uses 2-6mb of your RAM and very tiny on the CPU.

 

I understand, I did tick both AC Power and Battery power boxes in the profile and the Performance on Demand tab. Still, everytime I pull the AC plug out, max voltage goes back up to the stock 1.250V. Looked around in RMClock but still can't figure it out.

 

Just a thought. Did you check back into Windows Power Schemes in Control Panel to make sure your selected scheme is "RMClock Control". I think I got bit there once

 

so, my only shot is to wait for NHC, i hope we get it's update notified here along with it's guide if it has any different procedure that is.
for the time being, please let me know if temperatures between 60c-70c are normal for my cpu? as in they wouldn't cause too much harm, right?

 

I don't have the "RMClock Control" option available in my power plan

 

thanks, does nhc do SuperLFM?

is there a comparison site or something, im just wondering what its missing.

i like how they have included a stability test in nhc.
thanks again

 

Aha!
If correctly installed, RMC adds it's own scheme to the Windows collection in power panel. Windows has to give up power scheme control to RMClock or it will revert back to a Windows scheme upon a change of conditions. Did you check the box "Enable OS power management integration......" at the bottom of the RMClock "management" tab & reboot ?

 

for the time being, please let me know if temperatures between 60c-70c are normal for my cpu? as in they wouldn't cause too much harm, right?

 

ali check out cooling central, they have the temp thresholds of the average hardware. i think its within range, although i am spoiled by my <40 degrees under load

 

^ bro, that clearly states i'm in the danger zone.

 

I just looked, and it was already checked in. So I unchecked and rechecked the box, pop up told me to restart, i pressed yes but nothing happened. So i manually restarted but to no avail, RMClock is still not a power option in my power plan.

Do I have to uninstall and reinstall RMClock?

 

i was just trying to undervolt my laptop, i was trying to run RM run RMclock i get this error

"Cannot install or load RTCCore64driver Make sure your loading this application from a not read-only medium and /or a network drive, and that u logged on with administartor right wich i am!

Plz help

 

Im guessing you have a 64bit Vista.

Did you seperately download the 64bit drivers from my guide?

 

i had the same problem and same laptop as you.

in the folder there's already a RTCore64.sys. delete that one and save/install the RTCore64Driver into that folder and a new RTCore64.sys shuold appear and it shuold work.. try it out!

 

yes i did i got the link straight from the guide

 

just delete that file and them open RM clock? i tried that it didn't work

 

delete the file in there that says RTCore64.sys and then download the signed driver from the link on the first page into the RMClock folder in Program Files (x86)

 

Try temporarily disabling UAC and security programs.

Also try restarting.

It seems you do not have enough access to the file.

 

dude im sorry what??? ok i delete the file then what what u want me to download give me a link? i did re-downloaded rmclock after deleting that file i still get the same error!!!

 

I guess re-intall. RMC has to convince Windows that it is a legit power management option (only with a lot of user controls) in order for it to stick around boot after boot. Do you have all the "CPU default settings" unchecked, except the last one, default. Don't let RMC control slip away after closing the program and specify your custom startup state. Do you have RMC set up to startup wth windows. Need that. You're close, but not quite there yet. It's worth all the horsing around in case you jumped in head first lke I did. ha

 

update to my previous post with itunes stability....it is not RMClock after all.
itunes is really written poorly for Windows.

 

i just stumbled on this guide... tried it on my new Acer Extensa 4620 with Pentium Dual Core T2390 @ 1.86 Ghz (Merom-2m) I followed the guide got pretty good improvements. Problem is it runs stable at 0.95V at max speed which is the min it lets me set. Any way I can drop the voltages down even more???

Max Temp: 71C -> 56C
Min Temp: 40C - > 38C

 

So I just set the profiles page to No Management (On Battery & AC Power), and it will not actually do anything to my processor?

Thanks

Stu

 

I see, great to hear

Im afraid not. Intel has locked the minimum voltages after Pentium M's

Yes exactly

 

Are there any alternatives to RMClock for undervolting that include the new Montevina procesors? I was looking at <a href = http://www.cpu-world.com/sspec/SL/SLB4E.html> this [/URL] and noticed that they said that the SLFM VIDs could go down to .75V, but RMClock only allows me to drop my P9500's SuperLFM VID to .925V

 

RMClock doesn't really have an uninstall feature so I just deleted the program files and installed again, but my old settings applied itself again. I just unchecked and rechecked the settings but still no RMClock power option.
