Well, the parity line shouldn't be attached to anything, so parity/nonparity
shouldn't be an issue.  If you try putting the PC SIMMs in the first two
sockets and the regulars in the last two, you might see that.

If you've got black SIMM sockets on the card, you might want to call up
Alltech and describe your problem.  Their newer version of the card
(white sockets) supposedly works better.
