Hi all I curious as to what is the difference between these boards is one better then the other? The reason I ask is because I have both so if one is better than the other then I will use that board 
use the 1D4 ...in fact the best mobos are 2b or 1D4 despite what stupidity on forum says on timing fixes
I had a rev 1D1 and I sold because some A500 games not worked there but worked fine on a rev 2B
