Voltage

I just bought a new laptop and i am waiting for dell to ship it to me so i have been reading up on this website and a few others for how i can prolong the battery life and still keep some performance. i was just wondering what the dangers were in altering the voltage and if there was a good way to do it. any help would be appreciated

 

there are a million n 1 ways of playing with voltage, none of which id recomend... if u want madd power goto a hobbystore and get a few lipos for scale airplanes (not parkflyers) and a charger, depending on your skills and needs get a converting medium (or jumpers)... cosult your electrical buddies and use external add on pack

now that i think about it i believe theres a util called powerstrip or sumfin that is used for ocing but i used it to detune for taking notes... performance is hurt bad tho

 

Pretty safe, but not so easy to set-up unless you read the info thoroughly: http://cpu.rightmark.org/products/rmclock.shtml
Bit easier, more functions:

I undervolt my dual core with the first program. Was 1.263V at max, now 1.000V at max.

 

i purchased a dell e1505 with dual core 1.83 processors with 2MB cache/667mhz fsb, 100 GB at 5400RPM, 2 GB Shared DDR2/533mhz. just wondering what you guys might suggest setting the voltage at

 

It's a trial and error deal! Your processor may function at any given voltage or not, and it may not mirror someone else's settings.
Start highish and work down, always leaving 10% margin at least, as voltage fluctuations occur when i.e.plugging in to the mains, attaching USB devices etc.
For me,as I noted above, 1.000V is stable for a 10x multiplier on my 1.66Dual Core. But anything lower was BSOD/crash city
Therefore I suggest starting a bit higher and stress testing with Prime95.

 

the minimum voltage is different for every computer; you cannot go by what someone else has even if its an identical machine.

 

sorry to keep bothering but i basically am broke now because i bought this laptop so i want to make sure i keep it working properly. i was wondering if setting the voltage too low and having it shut down would be harmful. im somewhat computer proficient but nowhere near enough to understand completely what the effects of undervolting are. would this be best done with the windows power settings or with the nhc everyone keeps talking about. or can they be used together, im a little lost here as you may be able to see so help would be great
thanks in advance

 

In general terms, undervolting is pretty safe; you'll just have to find a stable voltage and then rip the benefits. Your laptop locking up or shutting down might be an annoyance, but if it happens (i.e. you went too far) it won't harm your computer.

Just make sure to save your work very frequently after you played with this.

 

thanks
that helps me mucho
