Let me know how you make out with what ever board you are using. 
I just got my 2600K 
 
Batch # L040B705 
 
Figure we might as well start early trying to team bin these batch numbers .......... 
 
Going with a ATX instead of a Micro now ..... 
 
 
Been doing a lot of reading but so far liking the UD5 for single card and the UD7 for multiple cards 
 
UD7 has ther 16x slots effed up IMO 16x16x8x8x 
 
I would have thought it would have been better to stager them for two card set ups giving them some breathing room
