so I am using the GA-990XA-UD3 MOBO and have had a problem with DPC latency from the get go. it effects audio terribly (pops every 3-5 seconds) and occasionally causes graphic glitches.
I have updated the BIOS, reverted back to previous BIOS, updated all drivers, disabled all drivers that can be disabled, and used software to help clean and delete any unnecessary junk on the computer that might be causing the problem; but the issue still remains.I am not certain if this is a common issue with this MOBO, as it is my second one (the first had the same issue and it was returned to Amazon.com). any help or suggestions would be greatly appreciated, as this issue keeps me from being able to fully enjoy my new rig.
below is an attatched screencap of my latency spikes.
my specs are:
GA-990XA-UD3 MOBO (obviously)
AMD FX 6100 6-core processor
Sapphire Radeon HD 6870
16GB Corsair Vengeance RAM
onboard Realtek sound (soon to be remedied by Asus Xonar DG)

The problem is easilly fixed but finding the culprit can be more troublesome. Latency is caused by bad programming generally. There are various rules for how a program should access the core and if it doesn't follow these rules it can result in the core not being released for the next operation and this causes a bottleneck that backs up. The biggest headache from our perspective is that we have to find the rogue program/driver.
The best way to tackle this is to go to Task Manager and then in the Processes section stop all the processes that are not required for Windows to run. If you do this one at a time until you find the one that is causing the trouble. Then depending on what it is as to how you tackle the repair.
If none of that works you would need to go to Device Manager and disable all the devices not needed to run the system. Then you can enable them one at a time and again see which one causes the problem.
Have fun!

Thankyou so much, never thought to access the processes, (because i am a little green when it comes to what is important) but i found the issue real quick. Turns out it is the ET6 GUI MFC application, which i never use and was unaware it activated at start up. where i was spiking at around 4k microseconds, it is now all under 200.
Thanks again

Good news there then. You were lucky in that you managed to find the culprit so easilly sometimes it seems to take forever. ;) Once again it was down to bundled software that was causing the problem. This is one reason I won't ever use any of it.
