Yes you are right. That _should_ have been reported.
I'm using the ASUS CUR-DLS with the ServerSet LE III chipset.
I was honestly convinced that such a motherboard is constructed for
server usage and stability. Perhaps there is something wrong with my
board.
Since you have to use ECC modules in this motherboard there is
no way to configure a special ECC config mode in the bios.

The bad module (1 GB) was installed in bank 1 beside another GB module
in bank 0.
The board reported 2GB of installed ram.
I put it then in bank 0 as the only module installed.
The bios then reported 16M as mem, which is wrong of course, but: no
error.
It's really funny since all memory tests with 16M were sucessful (using
memtest).
After that the board always reported 16M not depending on the bank
position _without any error_.

I really don't know wether I should laugh or cry about that ;)
All in all the system is now working stable with other modules (2x1GB)
installed.
