Vista - DPC Latency

07-28-2008

I just built a machine with the parts listed below. Runs fine Blu-Ray looks
GREAT. Problem is audio drop outs on Blu-Ray playback and when playing
lossless WMA across the wireless.

BIOS and all drivers are newest on the web. I've tried disabling everything
in the device manager one at a time. Removed memory and tried one stick at
time. Ran dpclat.exe and it shows DPC latency average 1200 with spikes up to
2000. Seems like if I do anything to cause HD activity it spikes.

Any ideas on what to try or a better place to ask?

Thanks

Google for TweakTown Forums. That is a Gigabyte support site. If you do a
search you will find what your looking for once in the Forums.

Hope that helps.
