While [re]searching PIC-X, PCIe x{1,4,8.16} internal slots and cards, I came across this
interesting usage suggested by a bright ICT author:
"...
A little-known fact is that you can install any PCI Express expansion card in any
PCI Express slot.
For example, you can install an x1 expansion card in any kind of PCI Express slot;
it doesn’t need to be installed in an x1 slot.
So, if you have an x4 expansion card but your motherboard doesn’t have an
x4 PCI Express slot, no problem; simply install it in an x8 or x16 slot.
The same holds true for “bigger” cards. For example, you can install an x16
video card in a “smaller” slot. (The slot, however, must have its rear side open;
otherwise, the bigger expansion card won’t fit. It is up to the motherboard manufacturer
whether or not to provide slots with their rear side open.) The only disadvantage is
that it will only have the maximum bandwidth provided by the slot; i.e., if you install
an x16 video card in an x4 slot, it will have only x4 bandwidth available.

Has anyone tried an x1 expansion (sound) card, esp. manufactured by Creative Labs,
in either an x4 or x8 slot?
I'd like to know how it has worked out for you, and how it has affected your system's other slots?
Thanks,
