    RS480M2-IL
    Athlon 64 3000 Winchester
    (1x) 512mb Corsair XMS DDR3200
    Samsung Spinpoint 160Gb SATA HDD
    Pioneer DVR-109
    Windows 2000SP4
    Power DVD6
    Drivers from installation CD

    Realtek audio driver 5.10.00.5761
    ATI Catalyst 5.6 drivers



    I bought this board to run a HTPC system and seem to be having problems with slow running and video playback.

    Apart from windows / drivers and PowerDVD nothing else is running on this machine, no firewall, virus checking etc.

    The first thing I noticed was how long it took to load windows, defrag the hard drive and load other applications, compared to my old Celeron 2.4 / MSI 865pe machine.

    Video play back using PowerDVD from the hard drive or DVD player is extremely stuttery, the sound is awful ( speech sounded like people were under water ).

    I disabled the on board sound and installed an old sound blaster card which improved the sound quality.

    This motherboard was designed by ATI to be run as an HTPC but I’m wondering if the onboard graphics (based on the ATI x300 graphic card) is good enough for DVD viewing and weather or not to buy a separate graphics card.

    What is considered the minimum spec for DVD viewing.


    Thanks for the help :)

    I'd check and double check all your bios settings and/or jumpers etc - and then check the DMA settings of the drives.

    Are they both using DMA mode (NOT PIO mode), and are you using the correct IDE driver?


    The x300 may not be the most powerful graphics card around, but it shouldn't have a problem doing DVD playback smoothly.

    I agree - would go and download all the latest drivers from the manufacturers website, rather than use the intall cd.

    Thanks MikeK, Lisag

    Will check they are using DMA and download the latest drivers.

    Is there an issue with the latest Catalyst drivers ?
    I heard the latest ones were a bit buggy

    I found the problem.

    Checked the settings for the hard drive and there was no option for DMA only PIO, so I posted on the MSI website and found there was a problem with the drivers for this board when using Win2000.

    I had a copy of WinXP which I installed, and it has transformed the computer.
    It now gives excellent video playback, disk defrags take seconds rather than 20-30 minutes and the computer feels fast.

    Thanks for the DMA tip MikeK :thumbsup:

    Oh yes - even the mightiest PC will be brought to it's knees by good old PIO mode on the IDE busses!
