The more effective bandwidth control method for you to make things obvious is --> underclock the processors, remove one of your dual-channel memory sticks, and underclock the left over memory.
This will make your computer more sensitive to DPC latencies.
All I get with the forceware betas is nothing but continuous spikes. In addition to audio/video playback I use Virtual PC extensively and occasionally Nero. Sometimes iTunes, VPC and Nero are working simultaneously. I've noticed some DPC spikes above my normal with Nero and VPC running but nothing ever stutters (normal=continuous spikes of 2500-3100µs with hacked forceware betas+nV PhysX drivers). Since I experience no stuttering I guess that I shouldn't complain about this but it makes me wonder on how accurate the DPC checker is and what are the actual effects of high DPC latencies on my system.
This is for my system only and by this I'm not suggesting that the DPC checker is not working. But it leaves some questions.
Your advise to downclock cpu, mem and go to single channel makes sense. I'll give it a shot as soon as I get the chance and will report back if I find anything worth reporting.
