DPC Latency issue Gigabyte EX58-Extreme

[Benzagel]

Let me start off with system specs:

MOBO: Gigabyte EX58-Extreme (Bios F12)
Video card : Radeon 4890
Sound card: x-fi Titanium PCIe
Memory: corsair dominator DDR3 1866
OS: Windows 7 Ultimate

I have had a sound popping issue ever since I made this computer last year. A friend of mine said to check the DPC latency using the DPC latency program. And wow, it has a ton of red spikes while my friends computer is stable green. I disabled non essential hardware to, as I was checking if it was the sound card / sound on video card or the network adaptors, and nothing came up positive. Even with all the hardware disabled I still had huge red spikes.

The screenshot is shown below.

Try this BIOS

Please use Qflash, DO NOT USE @BIOS, here is a guide
BIOS Flashing - A "How To ~ Qflash Guide"

There is MANY things that can cause this, it's best to start with the latest BIOS to rule that out. After that, or before if you want, please disable C1E and EIST in your BIOS and see if that helps.

Also, if installed, uninstall Gigabyte DES (Dynamic Energy Saver) and Easytune and see if either of those help. If that does not, and the new BIOS does not then it would be some part of your hardware or drivers as this has been corrected in the current BIOSes.

youll find that easytune and des are the main culprits,just closing easytune is enough to stop it






these are screens taken from my pc with and without eastune running,check or disable des too if you have that running

Heres my system. Fresh install of win 7 only drivers installed. No ET6 or DES installed at all. System is currently running at 4.7Ghz that is x20 loops LinX stable. 4.7 Ghz stable

what drivers are you using for lan and audio? the win7 ones or from gigabytes site? i use from gigas site apart from audio,i dont install those,is c1e enabled in the bios? i havnt got that enabled,its different things for different boards/components closing easytune stops it for me i dont have des installed

So the update to F13i made it terribly worse. Check this screenshot out.

Also I am using xfi drivers from creative ...and the lan drivers are from the gigabyte site.Attachment 2768

@Op not trying to take over your thread.

@wazza.. All drivers are from here Audio driver is 2.50 and lan drivers are 7017_03232010. C1e is enabled.

I was just surprised when I ran the program and saw my spikes worse then the OP's. I thought they would look like yours.

I notice nothing wrong with my system untill I saw that. I went ahead and disabled both network adapters one at a time and both High def audio devices and also 2 windows slideshows devices one at a time and still no change.

@OP and any one else readying this or having Audio popping problems. Check your overclock settings. Mainly Vcore. I noticed while redoing my overclocks and pushing to 4.7 that raising vcore to either get into windows or to get stable would take care of the popping sound for windows startup. So if your stable try raising Vcore 1 or 2 notches and see if that helps. I have no audio popping at 4.7 I will try my 4.5 setting again and see if it happens then. I know before this most recent install of win 7 I was having the audio popping on start at 4.5. but just at start up all other sound seamed to work... All this is with the built in audio.

ace,you can disable c1e its probably that,i dont enable it now i use the work around which is to select balanced power saving profile from windows7 power options and same can be done in win xp power saving but its called minimal power management,they both do the same job as c1e but less latency and mb squeal,as for f13 bios its useless,best to use the latest official

[Benzagel]

Hi htere, here is a screenshot I put all settings to defualt... no more OC using F13i bios.

Also I disabled soundcard and using latest drivers for the LAN from gigabyte...the problem is still there and the same, in fact ... even worse than the F12 bios.

you need to use f12,try without your soundcard and see if theres spikes,just enable azalia codec and use onboard,my guess is its your creative card drivers
