Building a system for a customer based on Tyan FT77A, with eight GTX 780 cards. Can't get more than 7 cards to work - the 8th one to come up reports code 43. It is not related to slot or card - if I disable the 'code 43' card in device manager, then disable one more card (total 6 active), and re-enable the one that was 'bad', it comes up fine (total 7), but if I subsequently re-enable the formerly good card, it starts reporting code 43. This happens both in Windows 7 and Windows 8.1. Tried all sorts of BIOS settings, nothing seems to help. Has anyone gotten something like this to work? Tyan officially only support Tesla cards, and those are completely uneconomical.
wasn`t code 43 something to do with correct drivers? Maybe a clean install/sweep on safe mode?

Try regedit fix at 6.9 on page 20 of OctaneRender Manual. I'm using the LGA 1366 version of that Tyan box.
Because I have 180+ GPU processers in 16 tweaked/multiOS systems - Character limit prevents detailed stats.
