Now test again and report back what you're seeing.

And by the way, did you run the DPC Latency checker right after installing windows? Don't install any drivers or anything else. Run it right after you hit the desktop. If it's good, install drivers/attach devices one by one and keep checking if it comes back. That's the only way to pinpoint the problem. Good luck!
I did a fresh install of windows on my second harddrive and the first thing I did was fire up the checker and it still had the problem.

Either way Ive pin pointed the problem down to my cpu, as I was actually able to boot up into windows with no DPC issues by only running 2 cores and no HT, but I havent been able to reproduce it(saved the BIOS settings but they dont seem to work anymore). Changing the various cpu settings in the bios is the only thing that effects severity of the latency.
