I’m hearing through the grapevine (and infinity fabric 
) that DDR4-4000 is Zen3’s sweet spot. Just sayin’!

Anybody got some experience OCing Zen2? I gotta admit, I’m a bit out of my depth with this. I tried the DOCP setting of my ASUS motherboard and that took my 3700X up to a little over 4GHz, but it wouldn’t run stable under load with that setting. I’ve now set the CPU multiplier back to 36 (stock 3.6GHz), where everything works. I’m more than ok with the performance I get like this, but I’m curious why i can’t get a little more out of it (I also tried 3.8GHz but it wouldn’t run stable under Linux, while it did under Windows).
I’ve heard similar stories from people running Zen 2 processors. Seems they’re not as easy to OC as Intel CPUs

Summary: Forget about it.
There‘s contests about who can clock it higher with no limit to the expenses.
But overclocking to gain a financial advantage - nah. It‘s pretty much built in, they maximize all clocks for each core all by themselves.

What’s a bit odd is that if i don’t use DOCP, it undervolts and -clocks my DDR4-3200 RAM to 2100 MHz.
Do you not use the XMP profile?
DOCP is ASUS terminology for automatically clocking the RAM. I did try it, but by default it wanted to set the base clock for the CPU at >4GHz, which unfortunately isn’t stable under load.
Is it automatic? I thought it‘s just using the XMP data from the SPD.
Yes, pretty much, but as i said, the CPU clock was way off the reservation.
I am a bit rusty when it comes to those things. But I would expect only the Infinity Fabric to change clock speed, not the CPU. Is some multiplier set manually to a specific value instead being set to auto? 
Edit: The picture is not what I wanted to link. The first reply in this reddit thread has good info.

I’ve failed miserably at overclocking my 3900X. I don’t really need to but, as you said, it would be nice. 
Anyway, here’s a new utility called ClockTuner for Ryzen (CTR). I haven’t tried it yet but it looks promising …
Even with the utility, OCing Zen2 looks like rocket surgery to me.

As I’m transitioning to a new Linux install (after 10 years my old one is pretty bogged down with leftovers nobody needs anymore, and reinstalling Windows on the new m2 drive has freed up a bigger SSD), i’ve gotten it to run stable at 200MHz over stock speed at stock voltages. Just turned up the CPU multiplier.
To err is human, but to really screw up you need a computer…

I haven’t been an AMD fan but I would still like to see the notes of you AMD builders and of you that switch sides. Keep all the data coming!
At work we got a few new laptops which are AMD powered whereas everything else we have (desktops and servers too) is Intel. They feel the same as the other laptops even under typical loads and use the same 65W power bricks and run quiet and cool under the normal light use. Seeing Netflix go AMD for a server refresh was also a sign to keep an eye out on them.
Like anything though and it’s been said here before - advertising vs. reality is quite a wide gap so I welcome the information you all provide to widen my perspective.

In benchmarking the latest gen of AMD mobile CPU’s blow Intels out of the water, and that is with tasks like rendering, compiling and gaming. I think Intel is also a little bit scared because they kept talking about the U4900 from AMD and never mentioned their own CPU until very late in the presentation. And bugger me if anyone knows what that was called. Though Intel has a thorough marketing and development problem.
I’ll wait and see what this next gen of AMD is going to do. It’ll be good but I don’t know if it blows everything out of the water, Zen has been iterative and that has worked out really well so far, let’s how this continues on for a while.
Meanwhile, in may I was looking at a R5 3600 for 165 euro’s, shopped my new PC but figured I would wait until prices would drop a little. Right now the 3600 sells for 200 euro’s on most sites…

IMHO, Intel got comfortable, and now they are in a position similar to where AMD was 8 years ago.
Their Architecture is showing it’s age, and they have nothing in the pipe but revisions and die-shrinks.
They are already re-structuring and doing the same thing AMD did after the launch of FX/Bulldozer/K11
And Jim Keller isnt available to save them.
