During the last past months AMD has released several AGESA updates addressing issues related to memory support and/or CPU performance in general. According to CanardPC, AMD appears to be working on a new B2 stepping in the case of their 14nm "Summit Ridge" silicon. The B2 stepping should addresses a lot of hardware-level issues that cannot be fixed by “simple” BIOS/AGESA updates.


According to CanardPC the changes are supposed to be related to the uncore area. This part of a modern CPU contains for instance the memory controllers as well as the PCI-Express root complex. Overhauling this area could help improving PCI-Express device support as well as better support and performance regarding memory.

So far this is only a rumor and since it’s not been confirmed by AMD we recommend taking this with a grain of salt. If AMD is really working on a B2 stepping this would be a bit of a bummer for all the customers who just recently bought and AMD Ryzen based platform. Although it’s a good thing to see AMD continuously taking care of their silicon it would be a pity if it could not be done via future AGESA updates.
