Summary: I'm running Windows 8.1. Technically, Windows 8.1 doesn't support Firewire, so a few tips on getting this card working. I installed the card, then installed the driver from the mini CD disk that came with this card. The new driver appeared in the Device Manager under the IEEE 1394 host controllers, with no problems, no warnings. But I could not get my computer to recognize my device (Cakewalk/Roland FA-66) that I attached to the Firewire card.
Summary: I have windows 7. I put this in and windows7 knew recognized it right away. There is no with setting it up. It worked great with my computer and provided me the firewire capability I needed for my presonos music studio with no hassle.
Summary: I bought this card because it was on a list of compatible PCI-E FW 800 cards on Universal Audio's website. I needed it for my Mac Pro and Universal Audio's Apollo interface. Since I installed it I have received nothing but crashes and FW errors. Universal Audio said they have since taken the card off their list because of people experiencing similar issues. By then it was too late for me to return the card according to Amazon's return policy.
Summary: TI chipset is very important when you're recording, especially with presonus gear which absolutely sucks when it's not set up perfectly. This installed without disks on windows 8 and plugnplay'd with a firestudio project just fine.
Summary: This card was not easy to install, but the default TI driver loaded by itself. Another reviewer suggested using it and staying away from the one on the disc. I tried that, and although the software I was using recognized the device I had plugged into the card, and did so right away, as soon as I started capturing I got a blue screen. After a reboot I confirmed that the same thing happened. I decided to try the drivers on the disc. They loaded. Sort of.
Summary: After installation in my Windows 7 computer I powered up and the driver automatically installed. I used the 1394 interface to control my Sony digital camera and had no problems. I am completely satisfied.
Summary: I was Looking For a card for an audio interface for firewire,and this one works perfect with my m-audio firewire 410!.. I bought another card and it was a Via chip that kept making my interface drop (flashy Blue Lights) out and pc didn't reconize. so if your'e looking for the right one for music production this is the one at a good price.
