    yes but its not as bad as f13,you need to test with/without c1e enabled and with/without your soundcard so you can narrow it down to whats causing it

    Hi there, I just performed another couple of tests. Note that these were done using the onboard sound card / latest drivers for them from gigabyte website. Also C1E and EIST were disabled in the bios. Using F12 and F13i bios in these tests.

    As you will see from the screenshots, the spikes were super high with the F13i bios using onboard sound. Using F12 bios with onboard sound, the spikes are not that high but they still exist in the red, and enough to cause problems.Attachment 2770

    i know it can be annoying,i still get slight mb squeal although i have a cheap psu,i dont know whether drivers cause latency or components like hdd's and psu's/gpu's

    seems to me gigabyte boards suffer from it the most,i dont know why

    Hi I'm his friend, we were looking at this a few nights ago and also I have another friend with a GA-790XTA-UD4 and X-fi Titanium pci-e that also gets the popping problem that sparked my time to research this problem and seeing the latest beta bios have the "Audio Bug" fix.

    I found that turning off HPET could help lower the high latency issue which didn't work for my friend here on the f12 bios but I am not sure if he tried it on the f13i. I tested HPET on and off with both f13i and f13j on my UD4P and I did see about an average 10 drop but I don't have any problems with high latency on my setup.

    Some extra info not included in my signature are:
    X-fi PCI card with 2.18.0013 drivers, not a PCI-e 1x card.
    Realtek network drivers version 7.23.623 (latest Win7 drivers on their site).
    C1E, C3/C6/C7 are disabled due to the motherboard squealing when DVID is enabled (I posted this back in the beta bios thread when DVID was just first added to the bios).
    EIST is enabled
    HPET (high precision event timer) enabled and set on 64bit.


    I may try the onboard sound later tonight to see if I get any high DPC latency with that.

    ^^ its not dvid that causes the squealing its c1e power management,the cpu only throttles down in speed and voltages when its set to normal or auto voltages which it needs to be for dvid to work or be unlocked so you can adjust it,you can still get round this mb noise and still use dvid if you disable c1e and use balanced power saving profile like i discribed above
    thats how i have mine set up

    Yeah my voltage/cpu speed is done through the Power Management in Windows.

    But then I never really tested c1e and the other c states prior to the addition to DVID in the bios since I was still really just starting to tweak my oc after finding what I could do with HT on and off and the bclk wall.

    Are you removing your sound card when you test with it disabled? Please do if you are not.

    Do you have another GFX card you can test with? These issues have been resolved in this series, so it has to be some driver (Which you are not installing so not likely this) or some piece of your hardware.
