tbred A or B revision? how can you tell?

[HotKetchup]

At newegg I found the tbred 1700 (model AXDA1700) and the 1800 (AXDA1800DLT3C) but I can't tell which version they are. Do you just buy it and hope?

on the earlier versions of the T-bred B's, they were all DUT3C
but now there are DLT3C versions
the most effective way is to look at its stepping which is mostly JIUHB

This may help also, although this may go into more depth than nessercary.
