I have been playing plenty with my new 5950x on an Asus Rog Strix b550-f wifi motherboard. CPU cooler is a 420 Arctic now with all brittle 3 fans working but at 580 RPM. CPU under various WCG tasks at about 4.5 Gighurts and 116 CPU power package and 60 C. Using CTR 2.1!
I will add much more later if everything is stable over several days.
I have on my own been trying different PBO / curve optimizer settings for 2 weeks now. CTR 2.1 seems to be stable and fastest for ALL core loads. I am trying to figure out what it is setting, but it typically gets under 10W for another 150 to 200 MgZ from what I can do in BIOS.
Like I said I will update, but for all core loads I can't match it so far. CTR does not beat stock bios single core loads, with stock motherboard settings, but I have not played with low / single core loads much as this 5950x rocks !
