Apparently 100% compliant IEEE 1394 isn't always

A couple weeks ago I put together a new system based on the Asus P4P800 Deluxe board. One reason I picked it was because it included 2 firewire ports, one with a back plate connector ready to go, the second on the board itself requiring a cable.

Well sadly it works fine with Vegas only coming from the camera. All attempts tested with several files trying to print to tape resulted in horrible jitters with a blank blue screen appearing every few seconds making the output useless.

The onboard chip is a VIA 6307 which is compliant to IEEE 1394a standards. I thought it may have been some BIOS configuration thing, but apparently it isn't since all you can do is either enable or disable, no other settings to adjust.

Installing my previous SIIG IEEE 1394 firewire card and using that, no problems at all. Aside from that I LOVE this motherboard. Will be doing some more extensive testing in the next few days (I hope) so far it screams through renders and yes, hehehe I broke the real time barrier in doing some simple renders converting from AVI to MPEG. How fast? A 20 minute render of test file (DV AVI to DV MPEG-2) was rendered in a few second over 18 minutes. I haven't even overclocked...yet.

Try forcing Windows to use the Microsoft driver for the firewire ports rather than the Via ones. Go to Device Manager, update driver, and pick "Let me choose the driver...."

The Microsoft Driver is labeled "OHCI-compliant IEEE-1394 controller," rather than "Via OHCI IEEE-1394 controller." Ignore all the Windows warnings and give it a whirl.

I had similar issues with a Via-chipset firewire card, and using the MS driver fixed the problem.

Perhaps wait for fall? [mumbled in grumpy voice as I sit here monitoring board and chip temps]
