4. Disabled all speed step, boost virtualization, hiper threading, power saving in bios
5. Rebooted the pc.
Shut down the pc and inserted pci firewire card and then started
then onwards my dpc latency shown negligible
later i enabled the onboard audio.. and installed audio midi drivers still all perfect
Good for you - you did yer research too on latency and stuff.
In my experience when you remove the drivers for reinstall
Use special software tools that hunt out all leftovers.
Then a good registry cleaner.
After reinstall - reboot between each driver
to settle the order in properly.
If you have a problem still
clear computer properly of driver leftovers/registry fluff
Then install in a different order/reboot between each install
Still have a problem - use different version drivers.
Drivers chipset/sound/lan/firewire/wireless/anti virus progs
- usual culprits
Quite often in past M/S updates used to affect drivers.
So you have to be aware of them - till they fix it.
