As I was searching some tech info aout windows 8, I've found something that can maybe very helpful for some DAW users one day if win8 has freezing issue :

The feature in itself is useless. It is supposed to "stop" the clock while the PC is idlying, in order to save power. The power you can actually save by doing so is laughable which makes this feature a joke for desktop computers (now for mobile devices it's another story and mobile applications will probably be built with dynamic tick in mind) . The reason why it's not working properly is because of what it is supposed to do. A great many deal of applications and drivers actualy depend on an accurate clock and "stopping" the clock kind of breaks that accuracy causing a gazzilion of problems. Forget fixing the damn thing and just disable it.

According to Microsoft, this problem is due to an issue in the interaction between the state-machine driving dynamic tick transitions and the state-machine-driving clock rate changes.
You can solve the issue by disabling dynamic tick. [To disable dynamic tick, type the command “bcdedit /set disabledynamictick yes” at an elevated command prompt and press Enter]. However, this method will reduce the battery life and power optimizations of your PC.


Must try, who knows

disabling turbo and HT should be automatic....

I understood that this "dynamic ticks" is not link to turbo, as it's only a win8 function

I now know that turbo mode can make freeze Scope...
IT'S NOT THE DRIVERS !!

that's correct. the problems created by Turbo have nothing to do with drivers.
Turbo mode is something that has been an automatic thing to disable since day one. it's been around longer than HT.
as you said, it creates timing issues. timing is even more critical than ever when realtime apps or hardware are used with a pc.

Turbo mode and HT are pretty silly concepts made for ignorant consumers. there is no way to magically make a processor core do more work than it's capable of doing. if the processor is fully engaged, it's doing all the work that it can.

there is no windows8 "freezing issue". your machine has a freezing issue and it happens with all of the operating systems that you've tried, iirc.

actually, i NEVER have to go through extraordinary convolutions to get a stable system. ever.
i don't doubt that you are having issues, though. i hope that you find the culprit.

Yes, it's not my freezing thing, but I think it can be interesting for ppl who use Win8, as this trick is not often described, and looks interesting.
I'm nearly sure now that it is this turbo mode that freezed Scope, as I now remember that I've always set it with turbo mode disable during months before the freeze happened. The last bios update must have changed it to enable by default...

sure. turning off Turbo mode is a good idea.

Core parking, c-states, speedstep, HT, turbo mode etc
They are crazy

yeah, but they're a good way to improve performance of offline processes.
