    You can try that, but I am skeptical that it will. If it resolves it, please let us know.

    Tried Bios A03 and the 296 drivers, it didn't fully fix the problem but DPC latency is lower than on A05 bios. Also encountering the clicking sound of the IDT power management(i have powercycle the check and uncheck in the advanced tab) on A03 bios. If i revert back to A05, the clicking sound is gone? What could be different from A05 and A03 that could hinder the DPC latency and the IDT power management clicking sound? Staying on A03 and the annoying clicking sound and hopefully Nvidia will fix it in their new driver with A05 Bios.

    yep, not matter what anybody said. the dpc latency thing is relative to the NVIDIA CARD OR DRIVESR. By the way loooong time brother Aiki!!!! :)

    It's really not that big of a deal lol.

    I usually get this kind of decent latency at all times. Running music produces even less latency.

    That's not a big deal though your latency is 20x higher than mine and if I will ever get a 10-20x spike it's still gonna be green, while in your case 20x = 8-10k which may already be unacceptable for audio work. In fact, many audio pro's require latency to be in the 0-100 range at all times. But like you said, it's not that important for most users anyway. If you can stay green during gaming, audio and video playback - nothing to worry about really.

    Exactly.
    Currently I have a M18x R2/680M SLI/XM in production...hopefully it will get around the same latency as my current unit.
