    My optical drives are slow to respond, are flaky, and sometimes do not auto
    start. I've been reading up on the subject and one person mentioned that
    changing the cable from the 40 wire type to the 80 wire type will improve
    the performance. Especially on mobo's that use the ICH7R chipset.

    Has anyone run into this on the MSI 975X boards? I think I'll just give it
    a try. I have a 80 wire unit laying around, and for the trouble of putting
    it on , I can find out if their is anything to this.

    I'm trying to run down some problems I am having with this mobo.

    Hi Wiliam,

    By swapping to 80 wire cable, surely will improve the datarate to and
    from your optical drive.
    Also you should enable DMA mode on your IDE channels. I have the idea
    your optical drives run in PIO mode now (and do not forget to check
    your opticals if they have the possibility to switch to DMA by setting
    a jumper).
    And I also suggest to update the IDE drivers for your mobo, this also
    can solve some issues.

    Good luck.

    40 wire cables will limit your IDE drives and CD/DVD to UDMA2 at best.

    My old mobo an ASUS K8V Deluxe, it used 40 wire on the optical drives, and
    80 wire on the hd's. All ran fine.

    This MSI 975X mobo, only came with one 40 wire cable setup, wrapped in a red
    sleeve making the runs round, but 40 count only. No choice, just one set.
    (4 SATA cables though, my hd is SATA by the way.)
