Clicking and popping with new cpu.

Hi I just improved my rig from an Athlon X2 to a Phenom X4 (all other stuff the same).  And now my old projects in sonar pop and click.  So, obviously I need to adjust something.  I increased the cache for playback up to 520 from 256.  Still pops.  I recall the only thing that's non standard in my setup is a setting for thread scheduling in the config file.  I set it to a *1* because I read that it helped with DSP processing.  Everything else is as Sonar installs it.  I haven't tried recording with the four cores yet.  Thanks for your help in advance

So the question is:  when one records in Sonar is it recorded with specific cpu stuff (e.g. certain threads for certain tracks etc)?

Thanks Cactus M, increased the buffer to 512 (it was only 256) but that begs the question, why would increasing the the number of cores on my cpu require a higher buffer?!

tenfoot, thanks for the link.  They're parked!

er, not parked!

Yes , seems to be strange,
Which drivers are you using  for the RME soundcard ?
Do you use  other soundcards ?
32 or/and 64 bit Win and Sonar?
 
 

This has really flummoxed me.  The latency and clicking and popping is really bad on my old projects.  They were fine with the Athlon X2 260.  I went from there to a Phenom X4 970.  Totally gobsmacked!  Even with a 512 cache there's clicking and popping.  I wonder if it's the virtual instruments and not sonar.

This might belong in Computers as it's smelling like a configuration issue, not Sonar. You should not have click and pops in this day and age. RME driver are the best and you should be able to run at low settings. Something is wrong. 
Many things cuase issues with building your own computer. 
The rules seem to make sure every detail is up to date, Bios, MoBo drivers, Video drivers, etc. 
SOmetimes HDMI audio drivers cause issues,, the list is long and easily googled.
That's why I said to run latency monitor as it normally tells you whats wrong. 

So, I guess it's just my old projects that are affected.  I can record with no problem.  Oh, well if anyone has any ideas that'd be great otherwise I'll move on.  I ran Sonar with latency monitor on and it had lots of page faults, but I really don't know what's causing it.  So now I've narrowed it down to just KONTAKT doing it.  ...and I don't mean area 51! :). Thanks for your hq iq.
