yeah, i know that. maybe i just got mixed up. you're trying to put a pcie16x card in a pcie1x slot? because i look at the slots physically, and i don't see how it could be done.
but if you have a pcie8x/4x/1x and you want to put it in a pcie16x slot, that could work.
i guess, with the little notch-thingies in the card, you could maybe plug in a 16x card into a 1x slot. but like 2/3'rds of the pin thingies would be sticking out. unless i'm really stupid or something, i do believe they're there for a purpose.
Heres wikipedia:
A PCIe card will physically fit (and work correctly) in any slot that is at least as large as it is (e.g. an x1 card will work in an x4 or x16 slot), and a slot of a large physical size (e.g. x16) can be wired electrically with fewer lanes (e.g. x1 or x8; however, it must still provide the power and ground connections required by the larger physical slot size). In both cases, the PCIe link will negotiate the highest mutually supported number of lanes. It is not, however, possible for a device to operate in a slot that is physically smaller than it (eg. a x4 card cannot fit in a slot which is physically an x1 slot — though it could operate in a x4 slot wired with only 1 lane).
as for bandwith, an agp8x slot provides a max of 2.0GB/s. pcie1x is 250MB/s. pcie16x is 4GB/s. thats culled from wikipedia.
