Intel screwed up again. (Have they ever NOT screwed up?)
So I'm reading http://en.wikipedia.org/wiki/PCIe
and discover a problem. A multilane card will
work (with reduced bandwidth) with fewer PCIe lanes,
but it will not fit into the smaller connector,
so this is only useful if your board has, say,
a x8 connector with 1 lane active. If the
mainboard has a x1 connector the expansion card
will not fit.
So if we wanted to build a card that could use
multiple lanes (say x4), it could not be used at
all in the common x1 slots. :-(
So we seem to have the choice of:
x1 card that could use x4
x4 card that cannot be used in many slots
Workarounds?
Maybe we could cut off the end of the
connector, risking damage to the mainboard.
Can we do the trick of putting a x1
connector on one edge and a x4 connector on the
opposite edge?
Make a low profile x4 card, and have a x1-to-x4
adapter? This would reduce the available space
on the bracket for external connectors.
