Re: DPC Latency issue Gigabyte EX58-Extreme

as strange as this may sound what PSU are you useing that may cause it as well

Re: DPC Latency issue Gigabyte EX58-Extreme

I have a Corsiar HX1000W psu. And to answer the previous question about the pump, the sound popping problems did not exist when I had windows XP, so this is entirely new to Win7 at the moment.

Re: DPC Latency issue Gigabyte EX58-Extreme

tried running your sound card software in windows xp mode (when in win7)in properties/compatibility?

DPC Latency Checker), I can see that after system startup, latency is good (in the green levels), but after running a day or so, it's perpetually spiking (running in the red). This is when I hear the horrible crackles and stutters. If I disable the network adapter (NIC), latency immediately drops to green levels and sound is good. However, if I then enable the network adapter, it immediately spikes perpetually into the red and I hear the crackles and stutters. I have to reboot to reset the condition so that it's running in the green (so that I can listen to music without horrible crackles and stutters).
It's not a driver issue. I've tried many drivers and swapped ALL components out of my system and I see the same issue.
I've swapped several different sound cards, internal and external. All have the same problem.
I've swapped several different nics. Some are worse than others, in that some take longer to show the problem after a reboot, but they all have the same problem.
I've swapped the Video Card.
I even swapped the MoBo with a similar model.
The only think I haven't swapped is the CPU and Power supply. Neither seem likely culprits for a sound problem.
The only thing that affects the popping is a reboot, which resolves it for a few hours, or disabling the network adapter, which resolves the issue 100%, but I sort of need network access.
It sure seems inherent to Windows 7. Something to do with the way that Networking and Audio interfere with each other.

Thanks for any suggestions!

Re: DPC Latency issue Gigabyte EX58-Extreme

are you using onboard lan? or a network card?

[Darryl_Gittins]

Re: DPC Latency issue Gigabyte EX58-Extreme

I've tried using using onboard nic, USB nic and PCI-based network card? I've swapped several different nics. Some are worse than others, in that some take longer to show the problem after a reboot, but they all have the same problem, regardless if the onboard NIC is disabled.

thanks for the thought, though!!

Re: DPC Latency issue Gigabyte EX58-Extreme

where are you listening to your music from? speakers or headphones? i can hear very slight crackle at loud volume if i have headphones on but nothing through the speakers,try and route the case audio/headphone front panel wires away from your gpu ect as that will affect things,there is electro magnetic interferance material its like a copper/aluminium sheet which you can use to sheild the nics or whatever you thinks causing it,ive seen some sheets of it on ebay for sale although i havnt tried it so cantsay if it will stop it,but 100% its a component or the mb itself thats emitting some emi

Could also be a hard drive?? Do you have a MiniPE XP?

If not google Digiwiz MiniPE XT and download it, then remove all your hard drives and test with DPC checker from within that XP and see if you get the same with no hard drives or drivers loaded.

Re: DPC Latency issue Gigabyte EX58-Extreme

It's not related to the speakers, because I can see a direct relationship between the red DPC spikes and the noise. And I've tried several diffferent sound devices and speaker configurations.

I hadn't considered the hard drive, though I can't see how that could be, given how the problem is so predictable, in that it dissappears for a day after a reboot. If it were a drive, the problem would always be there, I'd think.

Thanks for the suggestions!

Re: DPC Latency issue Gigabyte EX58-Extreme

Hmm,for a whole day after reboot it's fine?

How about disabling the OS Performance counters, you'll need to Google how to do that. Maybe it is those counters stacking up data and then after a day or so starts causing issues?

That's a crazy idea... I like it!! I'll give that a whirl. Thanks man!!

Re: DPC Latency issue Gigabyte EX58-Extreme

Anytime!

If you can't find how to do that let me know and I'll dig around for you and see if I can find it. I know you can do it though as I've seen it suggested in SSD tweak suggestions at a few places

[Darryl_Gittins]

Re: DPC Latency issue Gigabyte EX58-Extreme

I was able to disable it using the steps and link here: Make Windows Run fast by Disabling Performance Counters*|*Internet Security Blog

Now I wait a few hours and see what happens!

Re: DPC Latency issue Gigabyte EX58-Extreme

Cool, how did the tests go with that?

Re: DPC Latency issue Gigabyte EX58-Extreme

Waaah! No luck. The DPC spikes are back. :(
Thanks for the suggestion though!

I'm going to try swapping out RAM next. Other than the CPU, I think that's the only thing I haven't swapped (hardware wise).
