    DH67CL B3 Audio and Video Drop-Outs (Scratching) - High Latency?




      I'm experiencing some drop-outs while playing audio or video. Here's my system:

      DH67CL motherboard B3 stepping (confirmed by Intel's application)

      8 GB DDR3 1333 Kingston RAM (2 x 4 GB)

      Core i7 2600 processor

      X-25 40GB SSD on SATA2 as my boot drive

      2 x Seagate HDDs on SATAs 0 and 1 in a RAID 1 (mirrored) array

      Windows 7 64-bit


      Most of the times the drop-outs happen when I open new applications and new browser windows/tabs, but sometimes it happens also while only playing. I'm using DPC Latency Checker and noticed a high latency peak happens everytime a drop-out occur (sometimes a high latency peak also occurs and I notice no audio/video drop-out). Hardly never I listen to a song and get no drop-out. The highest number of drop-outs I got was 3 in a row, 15 secs apart from each other.The highest latency peaks are about 43000 microseconds, most of them are about 36000 microsecs.


      I first thought it was a problem with the ethernet adapter. Disabeled it but didn't help.

      Then I thought of the SSD and disabled the pagefile. I sense fewer drop-outs (and latency peaks), but just a few less, it's far from stopping completelly.

      Tried copying songs and videos to my SSD and run from there, but it still got the same drop-outs.


      I'm using the latest drivers and firmwares as of today June 8th.


      Any ideas on how to solve my problem?


      Thanks a lot.

          By looking for answers over the Internet, I got some tips on Microsoft Answers and I'm pretty much sure my problem was caused by Intel Desktop Utilities. I disabled it and the problem stopped, the latency has not gotten higher than 1200 microseconds and usually doesn't get more than 200 (the peaks are around 600). The version I was running is Hopefully Intel will improve it on the next versions. I also had another issue with it, that I already posted: one of the temperature sensors had a default treshold of zero degrees C, and even if I changed it, the next boot it reset to zero. So I had to disable the notification for that particular sensor.

          Thank you.

            Just to add some more information, the IDU versions up to are still causing high latency and audio and video drop-outs. It seems that there is less occurrence of the drop-outs, but some still remain.


            Thank you.
