Zen +, Zen 2 and Zen 3 have already been activated for the open PCIe standard Resizable BAR.

Like first tests of community Member ' Maxxx800 ' from theComputerBase forum, the first generation of the AMD Ryzen Threadripper (test) from 2017 also supports the open standard Resizable BAR aka AMD Smart Access Memory.
