And like right now my dimm is at 59C where as the cpu and gpu are at 40C,
I'd say the GPU is at 59 C, as the DIMM temperature normally runs at around CPU idle temperature...in fact, right after a back to back Aquamark benchmark, check the highest temperature spike via FanGUI's histogram...that would be the GPU temperature.

Yes you are right it can be unstable if you lower it too much but modearte it and look in the forms for undervoliting the dothan safely!!!
I recommend typing so people can understand what you're trying to say. I'm not going to waste my time translating words that I don't know. Your runon sentances also give me headaches.

From what I understand your post says, you are saying it saves 30 minutes of battery life (instead of dropping in 3 hours, it drops in 3.3 hours). I'm ignoring the quiet point because we've already estabilished it's already quiet. And yes, it does decrease stability. Maybe not by reducing the voltage by a bit, but there's no real purpose behind it unless you really need that extra 30 minutes, something which I doubt many of you do.

Undervolting your CPU (properly) doesn't decrease stability, performance, or anything else except temperature and power consumption. CPUs have a production range that allows for higher and lower quality yields to reach the same standard. If you have a high quality yield CPU then you can greatly reduce voltage and not run into any problems.

Might want to look at yourself in the mirror buddy. The previous poster just acknowledged that lowering the voltage for good CPUs won't decrease stability, but guess what - not everyone has a good CPU. I myself have my CPU voltage lowered because I've been overclocking machines for going on 5 years now and know what I'm doing. I stand by my statement that for someone who doesn't need the extra time, the procedure isn't worth the possible loss of stability and frustration. Maybe you should head toward making constructive arguements instead of insults?

sure thats why my frineds undervolted laptop is so quiet and cool and get 30+ more min of batterY!

hmm, nah I don't think it is the gpu, for one it isn't in the gpu section. But beyond that, I don't see why the gpu would be that hot when I'm just doing stuff in windows that shouldn't push the gpu at all. I'd imagine the cpu and gpu being close to equal much more likely.

qwazi- I too am a long time overclocker and think I haven't degraded my stability. I'm sure you can, but just as you can properly overclock if you know what your doing, I feel you can undervolt as well.

I know you can, and I'm currently doing it (what is it with people on the internet and not reading posts), but my point is it's not necessary to generate near silent fans. I'm undervolting and guess what - my silent fans are still silent. There is an increase of battery life, but an extra 30 minutes is immaterial unless you actually need to use it for the full usage. Supposing you have a low quality CPU, you will probably be able to lower the voltage a minimal amount before experiencing a large stability drop. Permanant damage is extremely rare because the system will normally crash what it's unstable before damage can occur, but it is possible.

My point throughout this whole thread has been that it works yes, but why waste the time doing it for the extra 30 minutes of battery life? To ensure the system is stable, you'd have to spend a good amount of time running benchmarks to make certain there are no inconsistencies. Laptop<3, you seem to get off on undermining my knowledge of computers, but really you've given no basis for this whatsoever. Rather than be an antagonistic jackass why don't you take my opinion for what it is and make your own decision.

Thank you Mr. Broken Record.

Guess I'm just confused by the fact that you say it is pointless to do it and yet you say your doing it?

I personnally like the extra bit of battery life, and certainly like that it is a bit cooler, but truth is I just like to tinker. So while I could have let my computer well enough alone, what's the fun in that?

p.s. Oh, and yeah, I'm not sure what Laptop<3 is about. He is looking at vastly different laptops and really is overly excited about the m70 when I don't think he is looking to get it for what it is intended. At least from all the talk on game playing he's done. Do you do CAD or DCC work Laptop<3?

p.p.s. Ofelas- I stand corrected. Your right, the "gpu" temp is definetely off and isn't showing the correct temp. I was trying out newer modified drivers for my quadro that had a temp guage and while it wasn't exactly equal to my dimm temp(which I believe you are correct is assuming it is the gpu) it was close. Makes me wonder if I should just go back to the earliest gpu drivers it came with. The ones where you mention how it properly scales back itself in windows.
