Which almost no-one does because it's really complicated and almost impossible to know if it's stable or not.

But thats what PBO is. It's using the same tool.

That's one hell of an oversimplification of what PBO is.
Power is just one component of a PBO overclock.
It is still using p-states regardless of the input parameters. Nor is PBO automatically stable.
So you should be able to manually achieve the same. Anyone that puts in the effort should be able to.
The difference between p-states overclocking and all-core overclocking is 200mhz at most anyway.

mine is Pstate oc :] And its 100% stable. Pstate OC is the Real overclocking on ryzen heheehe
So your R7 2700X is at 4.24 GHz...is that max boost or all core boost? Does it still go to 4.35 GHz single core like it would at stock?

nope im at 4257 drops to 22xx had it dropping to 1000 but felt to slow for browser hahaha.
PBO oc sucks for anythign else than gaming. Stability with it is just crap on heavy loads could not get that stable no matter what.

Well, my CH6 with PBO and PE Level 4 has always been as stable as a stable thing, bolted to a stable floor with some very strong bolts. Ok, not at 4.3Ghz allcore, but defo at 4.25Ghz all core. And yes it does auto downclock to 2.2Ghz @ 0.813v when idle.

no matter what i it ey cant pass ibt high x10 so dropped it after week of messing around.

Then maybe @Zeed, the cherry picked 2700x you paid over the odds for isn't as "cherry picked" as you were led to believe.

I'm not sure why people think they can do a better job than AMD engineers with their overclocks.
Well typically factory settings have to be very conservative for the very worst chips so there's always going to be some headroom on 99% of chips. Also they're never going to be configured for maximum performance out of the box because the TDP has to be taken into account.
Don
And they have to cater for lower quality motherboards as well, particularly as regards power regulation.
Soldato
Of course they do. But with the right mobo and the right cooling that changes. For a start TDP goes out the window, otherwise how do you explain my clock for instance ? In fact, TDP goes completely out the window and all the way down the road when i put my rig under phase.
Soldato
Yes, and yes. It will never take you over the limit's of your mobo and cooling though.

...and neither will a manual overclock, unless you like your setup fried. That's the point; irrespective of what your setup is, PBO will find the optimum performance automatically, and it'll still clock down when idle.
If you're not comfortable with your limits being dynamic then you don't switch PBO on, and just allow PB2 and XFR2 to do their thing within the predefined limits.

Seems wise, there's no way I'd be buying Ryzen 3000 just yet if I had an 8700K especially with a bit of an overclock unless I absolutely needed more than six cores for work. For gaming and pretty much everything it should be fine for a year or two and probably much longer.
Haven’t had an AMD cpu in over 10 years.
My experience with Intels boost clocks - was that As load dropped during game the clock speed on the cpu would drop. Then under load it would shoot up again. This constant up and down of clock speed created microstuttering in the games. This is actually the reason I started o erclocking cpus m, not for performance but games run much smoother on Intel when clock speeds stay the same and don’t fluctuate
Does this happen on amd as well?
Potentially not as much with this generation, as the time taken to adjust clocks is in the order of single digit milliseconds rather than 10-100x that (I think earlier gen intel were worse than recent gen). The granularity of the steps is much smaller as well I think, which may or may not be related.
Will be very happy if it works, but will have to wait for reviews or (more likely) experience from forum folk more eager than myself.
