Hi!

Is there any software where I can undervolt the SP9600 in the T400s?
On all my previous T series I managed to undervolt the processors, I want to do it on this too. On Windows7 64bit.

Thank you!

RMClock can be used to undervolt processors. However, it does not provide positive results for LV/ULV processors in my experience. I tried it on a X61s with an SU proc (can't remember exactly which) and even the lowest settings were more power hungry than stock voltages. Probably a limitation of RMClock.

Don't suppose someone could hack it to accept lower voltages (My P8700 bottoms out at 0.8750V for LFM, 6x, and 7x)
