I'm looking at updating the errata for old AMD CPUs and would like more precision on which CPUs work
and which don't.
Athlon 64 x2 and Phenom II x4 are confirmed not to work. It appears anything less than Bulldozer, which
introduced AVX, will not work with all algos.
If no one has data that says otherwise I'll update the errata in the OP.
These CPUs are working fine with legacy versions on
zr5 algo.
I haven't tested other algos, since I have no interest in them.
m7m also works if I recall corectly - will test that on a weekend.
