Due to AMD attempting to eke every drop of performance out of its chips, you won’t see “a whole lot of manual OC headroom” on any Zen 2 desktop parts. According to AMD’s senior technical marketing manager Robert Hallock, it’s more beneficial to overclock your chip’s memory and Infinity Fabric interconnect rather than the processor itself.
“The other goal of our engineering effort is to absolutely maximise the performance of the product out of the box,” Hallock says via Reddit. “By designing algorithms that extract the maximum silicon performance automatically (e.g. Precision Boost 2) without asking the user to tinker or risk their warranty. So, no, you’re not going to see a whole lot of manual OC headroom. That’s just performance an average person – who doesn’t know how to OC – can’t access. Why would we do that? It is not our intent to leave anything on the table.
“It’s more beneficial to enable PBO (Precision Boost Overdrive), overclock the fabric, overclock the memory. But that’s true of Ryzen 2000 Series, too.”
