Well I tried shot gunning and moving the io express to slots 3 and 4 which have 8 lane configurations but I get the death screen on boot if the aja io express hba is in anything but slot 2. I haven't removed the ati radeon 1900 from slot 1 because then I'd lose my computer screens. I did remove the atto celerity in slot 3 and the extra video card in slot 4 also a radeon but a 2300 or some such. with nothing but the 1900 in slot 1 and the aja hba I still get death screens when it's in slot 3 or 4 with nothing else in. The computer boots for a while with the spinning grey wheel then death screen writing. Oh well so I change the lane configuration to give slot 2 8 lanes unfortunately that drops slot 1 to 8 lanes also. Things do seem to be working but when I tried a fake digital cut using local mode I still get a stall roughly 90 seconds in. This is a video mixdown one video layer sequence with a stereo audio mixdown. Media is on our medianet unity connected through fibre and the atto celerity card. I'm going to copy the media to an internal drive just to see but I think they already had the same results with that before. Doesn't seem like the lane reconfiguration changed anything performance wise. Of course I guess the radion 1900 card is now only getting 8 lanes but I don't know how much that would play into digital cut performance. Unfortunately I only have a single internal drive right now so I don't know if that will support a 220x video stream playback. I've had okay luck in a pinch with this type of media drive in my normal sndx. I'm trying to eliminate the unity and or fibre as a contributing factor in the equation. Oh well more fun on a Saturday night than humans should be allowed to have. ;-)
