Thanks for the link. I don't see anything addressing anything specific to open io or the io express. It does mention all 4 slots as mechanical 16 lanes. I assume that means depending on the expansion slot utility configuration any slot can have 16 lanes but not all slots can have 16 lanes at the same time on this circa 2009 ish macpro. I will have to dig through more aja manuals and contact aja support to see what they recommend. Is anyone successfully running mc 5.5.3 with the io express OS 10.6.8 and outputting dnx 220X media to HDCam/HDCamSR successfully without stalls. It seems like this should work I'm hoping it's just that I've got the PCI=E io express HBA card in slot 2 set to only one lane that is the problem. I'll probably just shot gun it and move the HBA to slot 4 which is set for 4 lanes and see if there is improvement.

Machine control etc... all worked but we could only output roughly 90 secs without a stall on dropped frames. I found it wouldn't even go more than a second when the output was set to 10 bit in the digital cut tool. Setting that to 8 bit and we could output 90 secs ish chunks. I tried media from both an internal drive and our fibre connected unity. I even added a sync generator and feed the deck and the io express reference but still just short chunks between stalls. I took the same project into my sndx mac and it output without a hitch. I'm wondering if the lane configuration could be an issue. right now slot 1 has 16 lanes with the 1900 radeon card. Slot 2 has one lane with the HBA card for the io express. Slot 3 has a celerity card for fibre at 4 lane. Slot 4 has 4 land with another video card that can be used

I thought I read somewhere that the io express only needs one lane but I may be misremembering that. Are slots 2 thru 4 all compatible so I could choose one of the other configurations and get 4 lanes to the slot 2 or should I just move the io express HBA card to slot 4 and put the extra video card in slot 2. The extra video card isn't feeding anything right now so a one lane slot wouldn't really effect anything would it?
