1800+ T-bred A's have stepping codes that end in A (i.e. RIUGA, AIUGA, AJUGA) and will probably overclock to 1.8 or 1.9 GHz.

1800+ T-bred B's have stepping codes that end in B (i.e. JIUCB, JIUGB, JIUHB) and seem to overclock to 2.0 GHz and higher.

I have a an 1800+ "A" and it hits a brick wall just below 1.850GHz even with higher voltage on stock air cooling.
 
If you don't want to remove your heat sink, you can at least find out if you have a T-bred A or B by running WCPUID.

T-bred A's are model 8, stepping ID 0.

T-bred B's are model 8, stepping ID 1.
