Difference with HT ON = +/-10°C
Only because you don't have all threads running anymore...
This is more an argument in favour of setting the number of threads used by an engine equal to the number of physical cores than to disable HT in the BIOS.
Ok, I won't disable it in the bios, IF you can show me an easier way to disable it.

I suppose Ronald means setting the number of threads equal to number of physical cores in Houdini Configuration.
Kinda messy I think... I prefer disabling HT once and for all in the BIOS.

My last thread was sort of a failed attempt at humor. It is still bios-disabled and I have no plans to change that.

Yes, there is !
If I do what you suggest, by enabling HT my CPU power requirements go through the roof ( to say nothing of the extra heat produced).
I may have put up with this as I have a 1500 W PSU and Corsair Water-cooling...but it plays merry hell with my Overclock, which I will not tolerate, all for no gain in performance !
So, HT stays disabled in BIOS.
What I meant was to turn-ON Hyperthreading but just let Houdini use half of the logical cores because it's the total number of Physical cores. Does that setup affect engine strength or else power requirement?

I wouldn't trust Windows 7 to babysit my pet rock.

Yes, I understood perfectly well what you meant.
What you don't seem to get, is that I have heavily overclocked my CPU and turning HT on sends Power Requirements through the roof apart from making my Overclock unstable, all for no benefit.
So, HT stays OFF in BIOS, for me.
