Who in their right mind would OC the 3700X that way lol your loss i guess heck i get like 4150mhz on all 8 cores with PBO on so why would i OC to 4.05Ghz and lose performance.

What Amd needs to do is allow us to control PBO and for Auto OC to automatically go up by the amounts we put even if its not stable let us control that.

I would really like to see this. I know from BCLKing that my 3800X can do above 4600 on some cores, but I also run into PCIe errors. I want control over whatever pre-set maximums AMD is passing along to BIOSes.

Iam glad i got the 3800x too bad all the reviewers where telling peeps to not get the 3800x for 40 euros more its a nice bump in freq imo
This is for OCing all cores 24/7 right? Because those mhz are lower then the boost mhz. And if you OC, will the CPU still boost single cores? And how many typical cores can be boosted at a time (without or with OC)? And if you OC a Ryzen, does it still throttle down at low usage?

Nope, with manual overclock your voltage if set manual will stay put and the core speed stay put. The clocks on that list stipulate for manual ALL CORE overclocks which is better in most cases than running stock. For example, my Ryzen 9 3900X runs 4.317ghz all core at 1.28vcore. Temps are pretty good as it would not even touch 80C when I test it with IBT Linpack.

Ok thanks, good to know. OC is not important for me at all, and if you at the same time lock your CPU so it does not throttle down, its a given for me that OC is not something I want to do. Heat and noise is important for me!

You're presuming something incorrect, I did the same initially. The CPU can and does still sleep cores in a manually overclocked state, even with Windows set to High Performance power plan with CPU set 100% min/max. With a fixed voltage in the 1.25v to 1.35v range one can get a very decent reduction in temps (and thus noise) during typical usage, and with a fixed all core or per ccx OC you can even perform better at the same time (with clocks on auto you will get lower perf for your lower temps). Typical Idle power draw for my 3700X is just ~20-25W.

The only real downside of manual all-core overclock seems to be a reduction in image editing, but you won't likely notice it unless you run RealBench.

Sorry, just saw this, catching up on this thread. ASRock X470 Taichi - non ultimate. I have an MSI X570 board as well, but I much prefer the Taichi BIOS, so i'm using it.

The worst 3800X is better than the best 3700X. At least looking at silicon lottery's binning and my own 3800X sample.
I've got a bottom barrel 3800X and it's still better than their best 3700X.
What would you call a bottom of the barrel 3800X? and how to measure? I can't seem to get passed 4979 Cinebench with PBO on, on my Mortar. I'll be getting a Gigabyte X570 Aorus Pro soon to see if that would pull the chip ahead. New Agesa should improve things too.
