DPC Latency Issues

Hey everybody. Lately, I've been trying to fix my high DPC latency issues. The problem mainly manifests itself in the form of crackling audio/freezing video all across the board, whether it be browsing the internet or watching a video in VLC. The only half-fix I manged to discover is setting my computer to operate in "Power saver" mode via Windows power options. Although, naturally, my computer starts to run much slower a result. If I have it set to anything higher than that the freezing/crackling returns.

The only way I've managed to stay in "High performance" without crackling/freezing is by uninstalling my display adapter's drivers. Even then, the DPC latency is still pretty damn high. This is my current situation, by the way.

All my drivers are up-to-date. My BIOS is the only thing I haven't updated yet. Any help at all is much appreciated.

Make sure BIOS is current.

If you have an Internet Security Suite installed, temporarily uninstall it using the appropriate removal tool, if available -

I tried uninstalling my anti-virus software and there's been no change to my latency at all, I'm afraid. I'm using Avast, by the way.

I believe my BIOS is currently up-to-date. The only recent update I can find for it reads as follows: "P11-A2L". My current BIOS version is: "P11-A2". I think that first update must be for Linux, what with the capital L and all.

Hi SaltLamp,


Any chance you could upload a compressed ETL file? My data cap is very near :(

Oh, sorry about that. My bad.

It doesn't really matter now, though, since things appear to be stabilized. I recently installed a new GPU to replace my motherboard's built in APU and that seems to have solved my DPC issue. My latency measurements are much lower and I'm no longer hearing crackling, nor am I experiencing any freezing video.

I'll be sure to report back if things happen to get thrown out of whack again. Here's hoping against that. Anyway, thanks everybody.
