    Default GA-X38-DQ6 latency issues and BIOS flash problems

    I've had a GA-X38-DQ6 running XP for a while now and there have always been slight issues with timing. I use it for pro audio applications and I never quite reduced the audio latency to as low an amount as I knew the system had the potential for. (It's got 4GB and a quad core.)

    A recent series of problems with Windows XP and a dead GFX card prompted me to upgrade to Windows 7. I've had big problems with continuous audio drop-outs since then.

    The DPC checker shows short periods (about 1/2 minute) of green bars, which creep up over a few seconds to long periods (a few minutes) of almost solid red. Needless to say, audio drop-outs are frequent. I have a PCIe card (Emu 1212m) which gives crackles every few seconds and a USB audio interface (Edirol UA-25) which crackles horribly and suffers from frequent 1 second drop-outs.

    Something is clearly wrong.

    I haven't been able to find the culprit by turning off drivers. Either it's a system device or it's the GFX card.

    So, question 1 is: How do I find out if it's the GFX card?

    In an old forum post (from about 2008) I read (from a Gigabyte employee) that the latest beta BIOS update (F9 beta) fixed a lot of these types of issues. I attempted a re-flash, which has seemingly disabled USB mice and keyboards. It's also turned off USB and CDROM booting. (CD booting wouldn't work anyway without a keyboard...)

    It boots into windows fine, I just can't log in. And I can't access the BIOS to fix it.

    Question 2: Any ideas how to get in to my machine?

    :/

    flashing the bios will reset it so that any usb keyboards and mice will be disabled,you need a ps2 keyboard to enable usb keyboard and mouse in bios,as for latency try turning off easytune and des(dynamic energy saver)try disabling c1e in advanced cpu features too

    Thanks wazza300!

    I was hoping not to spend even more money just to get into my BIOS, but hey ho. I've tracked down a PS2 style KB... They're hard to find these days! I'll have a go tonight.

    as for latency try turning off easytune and des(dynamic energy saver)try disabling c1e in advanced cpu features too
    I haven't knowingly installed either easytune or des. Are they part of some standard driver install? Where would I find them to turn them off if I had them?

    I'll try turning off c1e as well.

    What are these things? Why are they there and do I lose anything by not having them?

    asytune is gigabyte software for monitoring voltages and settings,des is power saving software,c1e enables the chips power saving features

    you can buy a cheap usb/ps2 adaptor to save buying another keyboard,that should work

    Thanks!

    I couldn't get an adapter in the right direction. (I found one like the one you link to, but that wouldn't help.)

    No matter, 13 down the line and I have a PS2style KB.

    I really hope this doesn't happen to MOBOs without PS2 ports. That would be quite vexing.

    trouble is usb keyboard and mouse are disabled by default in the bios,so when you flash the bios it will reset,luckily mine works in the bios whether its enabled or disabled,but wont work in windows unless i enable it,but not all usb keyboards are the same

    Thanks for your help so far. This is all very promising.

    Things are a lot better after the beta BIOS update. The PS2 keyboard let me in to change the settings. After booting, the latency settled down... Especially after I turned off the on-board sound drivers.

    I'm now averaging 200us with occasional random spikes (every 15-35 seconds) using DPC Latency Checker. The spikes never really go beyond 2800us... Mostly they're around the 2000us mark. The latency floor seems less than half the height of the system pre-flashing and the maximum latency is much reduced.

    Audio appears pop free using the Windows drivers. We'll have to see what happens with ASIO... That's all on my other partition.

    I'm still worried about the spikes. Also, I sometimes get blocks of red and yellow activity lasting about half a munite. It seems to conincide with disk activity or monitor activity, especially loading up programs.

    Is this normal? Should still be worried?

    as for latency try turning off easytune and des(dynamic energy saver)try disabling c1e in advanced cpu features too
    I can't find des or Easytune. I can't find c1e in the BIOS either... Am I missing something?

    it might be called c1 on that mb,c1e is a newer version,as for easytune if you havnt installed it then dont worry about it
    have you updated the intel inf chipset drivers?



    thats what i get on mine but every mb is different

    Yeah, I'm getting a baseline of double the height of your bars, with spikes - sometimes far apart (15-30s), sometimes in big clusters.

    I found the c1e setting and I'm trying the chipset drivers now...

    Not much change from those settings according to the DPC checker, but I've gone down from 16ms ASIO audio latency (with frequent popping) to 5ms with minimal popping (only when loading external apps or inserting virtual audio devices)

    That makes me very happy!
