Comments on: My Solution for Dell XPS M1530 DPC Latency http://www.scottmetoyer.com/archives/my-solution-for-dell-xps-m1530-dpc-latency/ Things I'm working on Tue, 27 Jul 2010 18:05:09 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Tony Tiger http://www.scottmetoyer.com/archives/my-solution-for-dell-xps-m1530-dpc-latency/comment-page-1/#comment-134 Tony Tiger Tue, 01 Jun 2010 15:01:50 +0000 http://www.scottmetoyer.com/?p=31#comment-134 I have a Dell XPS M1330. Much the same as yours but with a smaller screen. I originally had Vista and had heaps of dropouts when playing Traktor Scratch. It wasn't too bad on the internal card, but as soon as I bought the NI Studio 2 DJ Card, the dropouts were about every 20-30 seconds. I disabled everything in the BIOS and Device Manger, but same issue. I wiped and installed Windows 7 and tried it right away and it was working perfectly. But then, I installed everything else including drivers and the problem was back worse than ever. It was when I uninstalled the video drivers and went back to VGA that I found the culprit and this led me to your post. I was going to leave it on VGA and be without graphics performance, aero etc, but now I can have both. You rock. Thanks heaps. TTT I have a Dell XPS M1330.

Here’s WPT’s window with ndis.sys DPC spike:

That was one of these spikes:

I too own an M1530: Mine has a 2.2Ghz Intel C2D proc. 2 GB RAM Intel 4965AGN wireless card nVidia GeForce 8600M etc.. I did the Windows Performance Toolkit thing just to find out its ndis.sys the process thats making my M1530 have high DPC spikes every 10 seconds or so.. The Max actual duration shows 6+ seconds on "function" 0x890086b8 and 1.5+ seconds on function 0x89008945. Searching on the internet makes me think its not an nvidia or intel (wireless) process, but rather one that comes with windows wich makes me think I cant uninstall it for example. Btw, when I disable my wireless card some spikes (the bigger ones) go away. Im gonna try and see if these spikes relate in any way to Nvidia's powermizer.. Other than that, dunno what to do. Any suggestions? Alex Hey very very nice tut/fix, thanx a lot.
