    Angry pumping buffer bars

    I am wondering why my W7 box is unable to feed two Samsung 223B concurrently, both writing 16x DVDs, without buffers (imgburn) constantly drying up on both writers?

    Is this a chipset issue or is sata2 multitasking performance this bad? Are sata2 channels truly independent or does one channel has to wait for the other to finish one transaction?

    the cpu is only 12% when when both writers are burning?

    any insight or better a fix available?

    it sounds ridiculous to me that my box can't feed two DVD writers without pumping buffer bars

    Could be chipset, or drivers? Could also be your memory speed or timings/settings

    Not sure as I don't personally use AMD myself, nor have I seen many users burn two disks at once so it may not be a largely known issue due to that.

    What software are you using, have you tried others?

    other writer software?

    the problem is that most writer software can't do more than one session at a time.
    That's why I like imgburn..when you have 3 burners you can open 3 sessions burning disks.

    Personally I have the inkling it's to do with the sata/ports/driver - me think the 770 sata implementation is shoddy in terms of multitasking.
    Not sure how the other AM3 chipsets perform.

    I would like to hear from others as well possibly testing the situation.

    my hardware is all on default optimised setting and should be plenty sufficient to deal with two lousy dvd writer, no?

    Ahh sorry, I saw you mentioned imgburn but just wondered if you had tried others as well. Like Nero, or imgburn while at the same time use a normal burn via windows just to test random burn scenarios.

    I agree, 2 writes is not much to ask from a system at all. Sorry I can't offer more advice, as I do not use AMD, nor can I test a dual burn on my board as I only have one burner right now.

    Nero can't do multi session, like most others around, and I don't like it anyway :)

    I hope others will chime in and test the situation - would be nice to see which chipsets actually work fine in terms of real multitasking.

    Ya, sorry I would test with imgburn but I can't tonight. I will try to though for you in a few days.

    Do you get the same issue if you burn once with imgburn, and once with nero or plain windows burn, or any other app like ultraISO, ect? Just trying to think of a way if you can see if that is a program specific issue or not

    single sessions working always fine with steady full bars - it's just multitasking where Win7 spits the dummy.

    we're talking Win7 btw :)

    Well OS aside, I was meaning to test with dual burns just using two different apps for a single burn in each. Or would that not be the same?

    nope that's not exactly the same

    for the test scenario imgburn (buffer bars) only should be used for concurrent sessions

    Ahh well I wasn't sure, I knew it would be similar anyway though. I'll try to get you a test done myself w/ imgburn in the next few days, of course it will be X58 chipset though.
