I can't find the 9640SE-24/16 anywhere, but presuming these are similar to
(or are actually) the 9650SE cards then each of them is using 8 lanes of
the 16 available. I'd need to know the exact motherboard or system to
even have a clue what the options are for adjusting the BIOS and whether
they are shared or independant.
But I haven't seen one where there's any real ability to adjust how the
I/O is partitioned beyond adjusting what slot you plug things into so
that's probably a dead end anyway. Given the original symptoms, one thing
I would be suspicious of though is whether there's some sort of IRQ
conflict going on. Sadly we still haven't left that kind of junk behind
even on current PC motherboards.
