First off this thread is created to share on the undervolting experience of users in here.
Warning!~ Do not try if you're worried about things going wrong!
I am not responsible!In the mean time please refer to the Guide link below..
Click! Me!The "Undervolting" Guide from NBR Forumer Click! Me!Advantages(According to FlipFire,NBR,2008)
- Cooler CPU (5 to 20c cooler)
- More battery life (15-30mins more)
- Less Fan noise & activity
- Longer overall notebook life
- Eco-Friendly
Disadvantages/Risks:(According to FlipFire,NBR,2008)
- BSOD (Blue Screen of Death)
****Only Risk so far noted, waiting for other forumers who UV their procs to share

Attention!~ Windows 7 Users!:When using RMClock on Windows 7 this need to be done:
in RMC in Management disable OS power management integration
in W7 in power plan in Minimum processor state set 100%
and now RMC is taking control of processor and Windows 7 of the rest
Update!~

27/01/2010 - Windows 7 Users!
Attention if ur using Windows 7 Follow this:
Management>Untick Enable OS Power Management Intergration
Also some ppl in NBR suggest to untick Engage IDA under the Advanced CPU Tab.
It could be windows 7 and RMClock power management conflict.. Since it wasnt developed for Windows 7..
