well i'm a semi-minimalist lol that's why i run RMClock and I9KFanGui... if my GPU was an ATI i would take a look at CHC...

btw, haven't read all the posts (feeling like crap) so unless your GPU is an ATI, i'd do what i'm doin' (that sounds really weird - redundant or something, but i have a fever so i'll use that as my excuse lol)

and I9KFanGui does show HDD temp...

ya'll just ignore me

It's definitely heading in the right direction.
No worries at all man , however I would definitely recommend shooting an e-mail to NHC's programmer and let him know your interest and want, I guarantee that there are others who want an HDD tray temp icon too.

Im a newbie to this. How easy is it to do? And how do I test 12-24hrs later for stability? So I should install the latest version of microsoft.net framework first and disable my laptop manu. power mgmt tool? Or will this one auto. do that?

I've tried it and it works really fine for me!
the voltage decreased from 1.380 to 0.924 (full speed 1600 mhz)
but for th minimal setting, I couldn't change the voltage because it's already at the minimum voltage (0.700)

thanks for the guide

Master Q, it's easy to do, just follow the guide. I'd recommend diabling your laptop power management software as it might conflict with your undervolting program. Go ahead and try it and feel free to ask any questions that arise.

Oh yah, here's a NOTE:

DO NOT use the NHC 1.9 beta 3, as it seems to have an huge RAM consumption and bogs down system performance (that and it has to be installed ). It was taking up 170MB of RAM when I noticed it an disabled it. I am now back to running 1.9 beta 2, which works just as well for my functionality.

How did you determine NHC was using 170MB RAM? Thx.

Easy, I usually run 200MB RAM usage, opened up task manager a bit after installing, saw 370, though wtf, noticed NHC, killed the process, back down to 200 again.

Although I'm not entirely enamored with Beta 3 (or Beta 2) I'm not having that prob. My Task Manager Commit Charge only drops 50-60MB when I kill NHC. Various utilities (pslist -m and ProcessExplorer) say nhc.exe has a "private mem" usage of 48MB and a "virtual mem" usage of about 150MB (have to ask some geeker 'sides me about that). I may go back to RMClock anyway for its simplicity. I still have to run MobileMeter to see my CPU Temp graphed over time so I know what my gaming "was" doing throughout the game.

hey guys, i just downloaded both programs however (prime95 and rmclock). what do you mean by run calculations? im kinda new at this, any help would be great thanks

Prime95 is program that is used to to find prime numbers with an insane number of digits. Because it does such heavy calculations, it can be used to stress test a CPU by comparing calculated results with the known results. "Running calculations" is the term used for stress testing (select this option when you first install). Got to Options > Torture Test and select In Place Large FFT (Small is good too, but Blend really just tests the RAM). After that the program goes on automatic mode and starts calculating. Now you just let it run. If it gives you an error, meaning that a calculation came up incorrect, your CPU does not have enough voltage and you undervolted too far, raise it, and try again. 12-24Hrs stable is a safety blanket to let you know that your CPU will be stable and not crash no matter what you throw at it

Thanks a lot for the guide! I got my Asus M6VA down to 700 on the 6 multiplier and 1.036 on 15 (2 gig CPU). Very nice!

But forget about Prime95. Get Stress Prime instead. That makes nice real time logs, so you can let your computer do the testing during the night, and even if it freezes totally, you can see exactly how long it ran.

Hi everyone. I just got an Aspire 1804 and have a probelm with the noise already. It is dead silent during loading, then when it gets to the desktop it turns on its fan and stays on no matter the workload. Quite annoying.

The specs

P4 HT 3.2ghz 800mhz fsb
1GB ram
128mb x600 radeon

Can someone who may have this laptop or one with similar specs reccomend to me what settings I should run this program. I don't want to test for days.

thank you all

Mastiff: I use Prime95 and recommend it because it is tried and true and has never failed me. If it does fail, it does make a note of how long the test ran if you're looking to track it, but if Stress Prime does work please use it. Others might wish to test it too so we have more than one program running (hell, two would add even more stress).

strongboy: You have a laptop based on a P4, which is a desktop CPU. Undervolting (as of now) is strictly for Penitum M CPUs. The fan noise you're getting is because the P4 puts out an enormous amount of heat. My best advice would be to put an extremely thin layer of AS5 on your CPU and to get rid of the factory thermal interface material (TIM). However, this will void your warranty so I wouldnt recommend it if you dont want to do that . The only other thing I can see is lift your note book up in the back so that the fans can have access to as much air as they need.

hmm with the current version of RM Clock, then setting the profile to min and max, in my box there is only one value for Pstate , being pstat 0, and the values dont change when profiles are switched. can someone help me out here?

so i should leave it as it is? I am afraid to put new cooling gel on the CPU. i dont know how to do it! i cannot raise the laptop any higher than it already is by itself. what happens if i dont use new thermal will it blow out and break? i leave the laptop on and hardly ever turn it off

maybe i have to buy laptop cooler but i read that it is loud and will make double the noise with the laptop fan and i dont know which one to get for this model help me please

Pre-undervolting

0.998V at 8x
1.356V at 16x
Average of mid 30s idle HD temp, mid 40s to mid 50s active HD temp

Post-undervolting:

0.700 at 8x
0.956V at 16x
Average of 29 idle HD temp, 40 degree max HD running temp

System stable even running prime95 at 13 hours for each setting.

Haven't compared the battery running time (haven't used this lappy on batteries yet), but by looking at the voltage figures I believe that it makes quite the difference on my 9 cell!

If you have never put AS5 on before, I wouldnt recommend trying it on your laptop. It's a time consuming procedure and I'd hate for anything to go wrong: even when you try your hardest, sometimes things happen. By raising your laptop I mean to prop some object underneath the back of it. This raises it up at an angle and lets the fans not be so close to the surface on which the laptop is sitting, thereby allowing more air to get to them. A laptop cooler might help, but I dont think it is necessary. All in all your laptop is made to cool itself properly, there is no worry about heat damage or anything of the sort. You have your warranty if something does go wrong, and thats why I recommend keeping it as is. However, once your warranty does run out, I'd recommend looking at the manual (given or online) for your laptop and learning how to take it apart. That way you can figure out how to open up the cooling assembly and get the dust out of it that would have accumulated by then, as well as put some Arctic silver 5 on the core to help disperse heat. A standard cleaning/pit stop like that keeps your laptop going for years .

Has anyone written a tutorial on undervolting using Notebook Hardware Control (and not RM Clock)?

While I realize that the concepts will transfer over seamlessly for those of you that actually understand what a 'multiplier' is, some of us are just beginning to learn a little more ablout computers, and a nice hand-holding style tuitorial using NHC would be great!

I don't want to run RMClock because I have an ATI gcard in my Asus Z70Va, and I like to see the temps and such that NHC offers.

If someone already DID write such a tutorial elesewhere, I would love a link!

Thanks!

I figured out how to drop the voltage and test for stability using NHC and Prime 95, but only for the lowest multiplier (6 in my case), and the highest multiplier (15 for me).

What do I set the intermediate multipliers at? I need settings for 8,9, 10, 11 12 and 14. Is there a way to make the software automatically set the voltage for these intermediate multipliers?

Thanks! (I have already dropped 10c of temps in my Asus Z70Va! WOO HOO!

eh, NHC I havent really used. I use the previous version, CHC, which I find better and less of a resource hog. Intermediate voltages really mean jack, your CPU spends <1% at these speeds, so it's a waste of time to test for voltages. As far as undervolting goes, just keep going step by step while prime is running (its a pain in the ass with that built in self tester though). When you get an error, raise it a level or two and then test for 12 hours or so.
