Undervolting CPU in Windows 8 / 10 ? RMclock doesn't work any more.

#1 Post by zoltan87 » Fri Feb 17, 2017 10:26 am

So I have changed the heatsink assembly in my T60 with a T500 heatsink, and also done some modificatios to it with copper shims (on multiple places the heatsink touches the stell bottom plate of the keyboard, so that it can transfer heat there too).

The temperatures are a lot better then before, especially under load. My final step would be undervolting the cpu, unfortunately it can't be achieed with RMclock under Windows 8.1, as it's not supported. I have been googling for quite a while now, but can't find any information on this issue.

Is there a way to undervolt it on Win 8.1 or even Win 10, or it's simply not doable any more on modern operating systems?

NHC (notebook hardware control) with my T43p in Windows 10 works just fine!
I have no idea how that works in x64 though as Pentium M does NOT work with x64 anyways...
Note: can you try Windows autostart option? It doesn't work in my computer and I used task scheduler to start it instead because of the administrator privilege request (the privilege cannot be lowered without buying the full version)

I had a look at that program, unfortunately is is for 32 bit systems only. Also I am pretty sure that it is abandoned now, as I saw a 5 or 6 year old post there that their 64 bit version is coming soon...

Anyway, after doing more research I ended up using CPUgenie. It's not free, but it works like a treat, I am very satisfied with it. There is a demo version, but for the full version you have to pay $15. In my opinion it's worth the money if you appreciate a quiet and cool system. I will write my new temps and experiences down in the "Make your Ati T60 run cool and quiet" pinned thread.

IBM ECW from this forum here is by far the best choice now!

I am not sure whether that could work on my T60 as I use a 64 bit Win 8.1. I might will give it a try on my second T60 when I will get the time and money to set it up.

I have a T60 and use RMClock 2.3.5.0 in Win 10 and it works without any problem. I checked and it isn't even running in compatibility mode. As I remember I think the only thing was that I had to set the installation program to Vista compatibility but I'm not sure, it might have been another program.

Edit. Missed that you have the x64 version, I have x86.
