Hello,
In my case the application of the XXTweaks implies a lowering of the multiplier factor from 7,5 to 6 and thus a decrease in the CPU frequency from 2,4 to 1,9 MHz. As I pointed in an older post, I downsized the FSB, as Boleary suggested at that time, which is also a drop in CPU frequency, and it meant a improvement. Currently, besides the change in the multiplier factor, I've also lowered the fsb size so that the CPU is running at 1.7 MHz and I think there is some more improvement. So this seems to make sense. Of course there has to be a limit or at least an ideal point somewhere.
Otherwise, after a new W7 installation (again),
I don't want to rush in my estimation about the 0.9z-8-2 (Windows 7) version, so I don't need to eat my words again, but it sounds very promising.
