AMD Readies B2 Stepping of the Ryzen "Summit Ridge" Silicon

AMD is readying a new stepping of its 14 nm "Summit Ridge" eight-core CPU sili
con, which powers its socket AM4 Ryzen processors, according to Canard PC. The
new B2 stepping reportedly addresses a lot of hardware-level errata which can
not be fixed merely by AGESA updates. According to Canard PC, the changes seem
to be focused on the uncore components of "Summit Ridge." Typically, uncore r
efers to the integrated northbridge, which includes components such as the mem
ory controllers, PCI-Express root complex, etc.ꀊ
If the B2 stepping is mostly focused on uncore-level errata, it could mean imp
roved PCI-Express device support, and perhaps even memory support improvements
beyond even what AGESA 1.0.0.6 brings to the table. Canard PC reports that it
hasn't come across any CPU core-specific errata being addressed with the B2 s
tepping. The glaring FMA3-related bug has been patched through BIOS updates, a
nd most newer batches of socket AM4 motherboards come with the patch pre-insta
lled.

新步進主要是修復無法透過韌體修正的硬體錯誤
包括但不限於記憶體控制器及PCI-E控制器
