Undervolting of X61 - T7300 2.0GHz

#1 Post by jolly2 » Wed Jun 22, 2011 8:14 am

I want to undervolt my X61. It has Core 2 Duo T7300 2 x 2.0 GHz. I'm use TP Fan control to control fan. I've changed heat paste for a new, better one - from Arctic Cooling series. It's much better - on web surfing without flash temp stays on 54 - 55 Celsius degrees - probably this is, because I've set up TP FC to turn on fan on the lowest speed rate (in TP FC as level 1) when temp reaches 55*.

As I said I want to undervolt my X61. On X31 I used to use Notebook Hardware Control to manage voltage with success for over 3 years. Unfortunately NHC don't recognize my current processor. I didn't find acpi profile file for NHC. I found this kind of file for T60 which is similar unit, but that didn't help to recognize processor.

I found on web RMClock program to undervolt. I've tried it. Probably that will be good for my expectations, but it has many options that I'm not sure hot to set up. This is why I'm asking for your advise.

Does anybody know hot to set up this program to not screw x61 and get best results? Maybe there is another program which is widely in use and I don't know that?
And the last general question - please let know on which levels have you got your processors voltage?

I'd go with RMClock.

There's plenty of undervolting tutorials for RMClock.

With an X61 I undervolted, the temperature drops were significant. The CPU is a different one though.

The most important thing is to go into the Advanced tab and choose Mobile CPU; otherwise RMClock guesses (wrongly) that it's a Desktop CPU and doesn't show the lower voltages.
