This seems to have been an issue with my video card. I noticed the temp was high when doing nothing (79c) so I changed to a single display instead of dual and the temp dropped to around 50c in a few minutes. I haven't had this issue since-not even when playing games. Gtx 570 by the way. Maybe it's on it's way out.

The GTX5XX cards get very hot. Try to add a 3rd party cooler to the GPU.

Probably a good idea. Thanks.

So, I just registered, I was hoping you could help me fix this problem of mine.

The DPC Latency checker shows something like this


It's a steady pace of 1 big red line per 3 seconds. No matter what I'm doing, or even if I just restarted my machine, the latency checker always looks exactly like this.
Here's my etl file
DPC_Interrupt.zip

[MagicAndre1981]

the trace doesn't show any spikes except this small nVIDIA spikes:

Total = 2524 for module nvlddmkm.sys
Elapsed Time, >      256 usecs AND <=      512 usecs,    173, or   6.85%
Elapsed Time, >      512 usecs AND <=     1024 usecs,      5, or   0.20%
Total,                                                  2524

You use version 9.18.13.1407 - 314.07). Try the latest Beta driver:

Also, please don't run this ugly tool. This DPC checker was build for XP! Use LatencyMon instead!

[Foehammer96]

The driver didn't seem to help.
Here's what I got from latencymon

[MagicAndre1981]

upload a new ETL file.

Here you go

Your NVIDIA GeForce GTX 560 Ti shares the IRQ16 with a lot of other devices. Your Gigabyte G1.Guerrilla has 3 PCIe x16 slots.



Insert the nVIDIA card into one of the other slots and look if this improves the situation.

[Foehammer96]

Of course it would be something that simple.

Everything seems to be working fine now, thanks for helping me out.

[MagicAndre1981]

so the issue is now fixed? In which slot do you the nVIDIA card now?

[Foehammer96]

Yeah, so far I haven't had any problems. Looking at your picture, the card was originally in the very right slot, and now it's in the center.

Edit: Well, nevermind, apparently it's back to doing it again, this time even worse. It was doing this a while ago too, but I thought I somehow fixed it. Apparently not.
Could you help me out a little more? etl
Also, now it's only happening when I'm playing games and other things. When I'm not doing anything it seems to be fine.

the GPU is fine. This time it is the driver Xeno7x64.sys

Total = 41682 for module Xeno7x64.sys
Elapsed Time, >     8192 usecs AND <=    16384 usecs,      0, or   0.00%
Elapsed Time, >    16384 usecs AND <=    32768 usecs,      1, or   0.00%
Total,                                                 41682

Here you have a large spike. This is your BigfootNetworks Killer 2100 network card. The network card share an IRQ with the SATA controller and one USB controller.

Update the network driver and disable this USB controller which share the IRQ 19.

Hi, Andre. I've registered here because I've tried all sorts of tweaks and changes I've found on the internet and you seem to be the only person around who knows how to actually fix DPC latency problems.

Here's the basics of my system:

Motherboard is ASUS F2 A85-V Pro
OS is Windows 7 SP 1 64-bit

I've run the xperf based on your tutorial in the first post, and the culprit seems to be the hal.dll and related to HPET. Unfortunately, there doesn't seem to be any way to disable the HPET in the bios (the manual certainly isn't any help here). I tried instead to sync up the Windows 7 timer with the HPET but that didn't change anything. Any advice? Should I PM you my trace.etl file?

[MagicAndre1981]

yes, please share the .ETL file.

the largest spikes are caused by the tcpip.sys, others by the ATAport and NDIS.sys. Update the network card drivers.

the hal issue may come from your OC. Don't OC the AMD CPU so much. 4.3GHz seams to be too much.

Hmm, I am using the latest drivers for my network card, though.

I wasn't aware I was overclocking! O_O I just left the motherboard's default settings on. How do I change that?
