I don't have a suggestion, but find your question and possible answers interesting.
Arguably, it does not seem to matter much performance-wise how many lanes are used though (example).

First thing I would do is check that its power supplies (plural) are properly connected. Check that it's seated properly on the motherboard.

Could also be that only one of your many PCIX slots actually supports 16X.  This is common.  May also have a setting in your BIOS.
