Yes, what are currently shipping from AMD are B3 revision processors. The
TLB-look-aside problem is fixed.
There are other less-critical problems with B3, however. Specifically,
power-related compatibility issues with various motherboards due to
(according to the motherboard manufacturers) AMD changing the TDP late in
the release process. I can't give any specific names or models that we know
have problems, however. I can say that everyone involved is working on a
resolution--usually through PCB revisions of the motherboards. A number of
1U power supplies that have previously worked with all Intel and AMD
solutions are now insufficient, as well, due to 12V limitations. B3 pulls a
*lot* of power.
I've heard reports of b3 pulling more power than b2, not sure if that's just
the higher clock speed, or a b3 related change. Has anyone put a dual socket
B3 system on a kill-a-watt and tested it under load?
