Edit #2:
I've been doing some testing on the 3000G... Since it is a Picasso (Zen+ core) I was kind of hoping for around a ~4.2GHz overclock but my sample seems to clock more like a 1st generation Ryzen.
Maybe my 3000G falls toward the lower end of the silicon bin/lottery? I'll just have to wait for more samples to be posted up to find out for sure.
The Stock 3.5Ghz VID on my sample is (~1.3v) and it seems to run up to ~3.8Ghz with 1.3v. The voltage wall comes up pretty fast and hard for higher clocks... With 3.9Ghz my sample needs ~1.3625v/1.375v vcore and for 4.0Ghz it needs ~1.425v/1.4375v.
I have my doubts about it reaching 4.1? and I think 4.2 is out. The chip seems voltage limited not so much temp limited. The IMC seems okay... I'll be testing that some more in the future.
