  You're the second person reporting similar problem with ASUS K8N-DL 
board.  Please see the following threads.

  In the following mail, I've attached a patch which might alleviate 
errors during writes (as Alexander was reporting CRC errors with write 
commands), but it won't do any good if you're getting errors during reading.

  Carlos and Paul, do you guys know anything about this mainboard? 
Should we perform some special tweaking to get these boards work?  I'll 
dig 3112/3114 document further but I'm not very sure what I should look for.

  Thanks.
