    DUAL PCI Riser and vid+Sound?

    I have come to the conclusion even with my Jetway C7 MB running at 15-20% CPU Idle in RR still lacks speed when switching between menus and other apps. I attribute this to the small 64mb on board video. As most Mini ITX MB's I have only one PCI slot which is occupied by a SoundCard. I have used USB soundcards and do not want to go back. Would an Active Dual PCI riser work suitably for a relatively small aftermarket video card (128mb maybe) and the soundcard? Anyone running 2 on a split PCI riser? Possibility of SQ loss or complete failure with the 2 fighting over bandwidth? Any input would be valued. Thanks.

    Don't be so quick to blame the amount of memory on your video card for slow speed. Standard 2D graphics uses very little memory.

    For example, 800wx600hx24b = 1.44MB. Even triple buffered, that's only 4.32 MB. Anything above that is unused in 2D. Unless you're running in 3D, you're just not using that much memory.

    Start with basics. Check your task manager and see if any process is hogging the CPU. Are you running any flash animated icons, etc? Any background processes?

    That Via CPU isn't exactly that fast either. I'd be looking there first if you're worried about your CPU load.

    the VIA CPU is slow, the I/O handling of chipset is slow, the onboard S3 too (not the size of the memory, the chip itself). you are planning to drop money for the riser and a faster PCI graphics card, and the result will be disappointing... change the whole mobo for this money to a faster one ( especially w/o VIA CPU ), and you will be much happier

    I gotta agree with the above statements. I have a MII10000 and it is slow. It was not slow when I bought it, but software has progressed and Front Ends are more resource hungry now (well some of them). But I still use my MII10000 and dealt with the slowness this way:

    -Disabled windows services
    -Switched my front end from RR to Meedio
    -Added more RAM

    The biggest improvement came from adding more RAM so I would suggest that too.

    Yeah that was my first thought...I have an AMD FX-62 Dual core laying around. I figured I'd just replace the mobo with an AM2 socket mini itx board.

    I have the idle CPU down to 7-15% and still a little sluggish for my liking. But on an XP pro system in my house with that FX-62 loaded up with apps and not tweaked for performance at all..RR flys. Think I'll be looking at new mobo's soon. Thanks for input!

    i have a C3 1200 laptop. for the first time, looks fast. opening an explorer window is fast. but when i open the third window, and there are some flash animation it, the whole machine dies... with 512MB DDR, and a fully lightened nLite XP... and i found several similar info about all VIAs...
