Huge DPC Spikes UD3R Motherboard

post #1 of 37
Thread Starter 
Well I just built my self a new system for my self and after about a couple days of messing around I had some audio clicking. So I looked around and found out it was a DPC Lat. issue.

I cant seem to pin it down, I have unplugged all my USB devices Disabled just about every thing under the manager. Unplugged all my video cards but one. Unplugged all my memory but one. Reinstalled windows, took my hard drives off the raid. I have no flippen idea what is causing this.

Any ways my rig is as fallows.

X58A-UD3R Rev. 2
i7 930 OC 4ghz
6GBs of DDR3 1600
2x GTX 470s
1x 8800GT
USB Card
TV Tuner (PCI-E 1x)
6 Hard drives.

It doesnt do it all the time but when it does it does it for a while then it goes back to normal. I havent figured out *** is causing it. It will do it in a game or just sitting in windows.

Any suggestions?

Do you have easytune or dynamic energy saver installed? If so uninstall them one by one and see if it is either of those.

It very well could still be a BIOS bug though, since those are so new you might have to wait a while for a fix though if this is the cause

Nope, I have none of the Gigabyte software installed this time (Yes Easytune did spike when I had it installed last time but the spikes where never as large as these)

No idea what would be causing that.

I just ran DPC latency checker on my sig system in the middle of a LinX run averaged 9-10 us, and the biggest spike I saw was a split second jump (one bar) to 424 when all 8 threads spiked to 100%.

I'm thinking it's a software issue on your end, not sure what it would be though.

Edit: My laptop has much higher latency, but no spikes like that.

Can you list your full system specs, including any possibly relevant software/drivers?

Software the only thing I can think of is Firefox? Because I checked right after installing my drivers before installing to much (I guess I should have checked before installing those ehh?)

Let me know if I missed some thing?

Pics of the stuff and the rig if you are interested lol.

Try running Process Explorer and Process Monitor (available on the front page here: http://technet.microsoft.com/en-us/s...s/default.aspx) while DPC checker is running, so you have a better idea of what's going on when the spikes occur.

I was looping an audio track and noticed my latency peaked when the file was accessed (press ctrl+a to auto scroll process monitor, so it keeps up real time):

Yah its not software, I wonder if I should try in safe mode. (I cant get this thing to really go below 180 to save my life.) I took it out of OC and now I run in the 250s-500s... I have no idea.

Try a different BIOS?
post #9 of 37

There are no other bios >.< I have a rev 2 board

I actually installed windows to another drive to see if the DPC went down. If any thing they went way up.



That is a 100% clean install of windows 7 64bit. >.>

BIOS FB11 has been posted for your board, all the X58A's and EX58's all have Audio bug BIOS fix just released, so I think this may be the problem it is addressing.

Please be sure to update using Qflash and disable Keep DMI Data before the flash, then after reboot to BIOS and load optimized, then save/apply/reboot F10 BACK to BIOS and set your SATA/Disk settings and any other changes you need to before you load windows.
