If you have ASUS AI Suite II installed, turn it off. It will randomly start throwing latency spikes due to the motherboard monitoring it performs.
 
I had that impacting my Asus Crosshair V Formula occasionally. The 990FX chipset is rock solid and the SATA controllers or USB ports shouldn't pose a problem.

Come on Alex, dont get all self depreciating (especially with your edit of post)...you do an amazing job here....My quibble was about driver boost, nothing personal, the only win here is to help fellow Sonar users make the most out of their software.

Thanks I feel more cheery after reading this... It can be heavy going sometimes. .

If there was a tech hug smiley I would post it so i'll smiley this  and this 

Alex, your prepare setting seemed to be the pest bang right now. I think I need to replace the B3 or freeze it every time I use it.

Thanks Dave, it is USB and I am using a USB2 port. Another controller card may be a good idea, but this interface and the keyboard/mouse combo are the only USB items.

Definitely on latest chipset drivers?
Intel?

Oh OK, AMD:

The chipset is ASMEDIA. I put on the latest drivers for the ASMEDIA controller and the other USB options also have latest drivers.

Yeah again sorry didn't work out...

Hi, Conley.
 
I have been battling drum sequencing demons all day, and still have about 60 measures to put together by hand.  (I don't loop)
 
Anyways, I thought I would see where things stand for you at this point.  I do confess that I skipped a large chunk of the middle of these 3 pages, but did pop in about half way down page 2 through to here.
 
Have you ever run DPC Latency Checker and/or LatencyMon?  These are freeware programs that you would download and run, to get an idea of your system's basic ability to handle streaming audio, such as what Sonar does.
 
Last I checked DPC Latency Checker does not run on Windows 8, but works great on Win 7, and LatencyMon works well on both 7 and 8.
 
Here is the link for DPC Latency Checker: http://www.thesycon.de/deu/latency_check.shtml
 
And, LatencyMon: http://www.resplendence.com/latencymon
 
Run one or both the above, without Sonar running, to get an idea of where things stand at the system level.  If there are latency spikes outside of Sonar, then those need to get analyzed and resolved prior to dealing with any performance analysis/resolution within Sonar.
 
I am off to sequence up some more drums, but will gladly escape frequently from that to check on this thread and a couple of others I am looking into.

Conley,
 
Oops, I said the same (should have refreshed the thread).
Running the tools can report if something is taking longer than it should.
The latency check tool is good for a general view but won't tell you why.  
The resplendence one will report specific driver names and is more useful for trying to pin down a cause.

My system is at a great performing setup I believe. I think X3 may need to be looked at with reference to RME drivers possibly as suggested earlier.

After booting my system this morning, all indicators of performance tell me that I should not be having these issues.
 
I still get pops and clicks on start stop, 80% of the time, and during playback and some recording with playback.

@Guitarmech111 - thanks for going through that exercise.  That DID show your system as being quite capable of handling the streaming audio, which as a good thing.
 
So, apologies if you posted this earlier, but can you please post:
 
1.  Sample Rate in both Sonar and for your audio interface
2.  Record Bit-Depth in Sonar
3.  Audio interface ASIO Buffer Size (or whatever they call it on your interface)
4.  Latency values reported in Sonar (input, output, total roundtrip)
 
I suggest a starting point: Sample Rate of 44.1 k or 48 k (Sonar must match interface on this), ASIO Buffer Size of 128 on audio interface, Record Bit-Depth of 24, record and playback buffers of 512.
 
At least your system should handle it, so hopefully some tweaking of settings can help some.

I use 48k/24 bit
128 - 256 samples in the ASIO buffer panel for record and playback. 256 seems worse, but that may just be a fluke.
No ASIO4ALL installed
155, 196 and 351 latency values.

Thanks Bob.
