B-die is pretty weak IC ,I see a lot of posts about IMC being weak ..that's BS they just weak IC and you need to bin crap-load for 4000c12 which means absolutely nothing if you can't get your secondary and thirds tight
Tested 3600c16,3600c17 and now I'm running 4000 Geil kit (OP shows 4133 kit -I don't think this are B-Die ,more like E)
if you can't run 32M stable in 32bit OS might as well send them back ,good luck finding the right kit
Edit;two DIMM board is a must to get you money's worth with B-bs
