Ok, now I know somethings up... just took the time to do a dirty stability test on 4.1 (4.0913 actually) at the same 1.3v setting in bios... stable... will see if it holds for long term, but I know for a fact I used to have to set voltage up to 1.35+ with much higher LLC setting to get it stable before... unless I'm getting THAT old lol... and yeah, vdroop still dropped to 1.25v during the test... even at desktop it never hit the set 1.3v... usually around 1.275 at desktop.

I wouldn't get too excited, could be down to just something they fixed in my board... always seemed to take more voltage on my board clock per clock compared with other people... but so far been folding all morning and no issues running 4.066 ghz with 1.3v set in bios... vdroop bringing it down to 1.263 folding... under avx stress tests it dropped down to 1.25v and still passed.... I'm thinking of trying for an even 4.1ghz at the same voltage... although it would end up being more like 4.091 or so due to the bclk being off just a bit.... I set the all core clocks to keep precision boost from going crazy though... was constantly hitting 1.45v holding 4.2ghz + when not really needed.

edit: had to go back to look, but seems like before it was taking 1.35 v to achieve the same clocks I'm now getting at 1.30 (1.25ish under full load)... nothing major, just noticeable...

I have not updated OP here in a while but a lot is still correct, link.

In regard to high voltage on low loads/core count that's normal and is not an issue as current draw would be low. You are best of referencing OP this thread and then this post.

Same goes for using XMP for RAM, it can't be overclock if you only set XMP to it's highest setting, the frequency RAM is made to run and is tested at. Only above XMP settings could be called overclock.
As for voltages at PBO/XFR, that's BIOS's job and many versions pushes to or above AMD defined high end of 1.5v with an excuse for "stability", most of times controllable by negative offset to lower that maximum or plus offset to get higher voltage when needed.
I don't know either, but maybe this is partly AMD/ASUS/other MB vendors fault to some extend. If XFR had been named XFR in the BIOS I probably wouldn't question it. And there so many post on people being concerned about the "high" Vcore.
I'm coming from 8 years on an Intel platform, so maybe it is just my head who is used to work on "old" accepted Vcore and old fashion all core OC

It is only when OC2 is enabled I reach the advertised boost speed of 4.35 GHz.
So I will keep OC2 on assuming this is just XFR and the processor is working as intended.

Also found this post on the AMD forum where they quote Robert Hallock about the Vcore boost.

My 2700x

Just completed my custom watercooled X470/2700x build and used that Asus/Ryzen buyback campaign.
X470 Crosshair Hero VII Wi-fi (BIOS 2801)
Ryzen 2700x
G.SKill Trident Z 2x16GB 3600MHz CL 16 kit
360+240 EK SE radiators
Kept my Fury X, for now

Have not done extensive memory testing on it and planning to run memTest86.
D.O.C.P set to 3603 16-19-19-39. No stability issues yet in the few hours of game I have tried.
Any suggestion to which tests I should run?

I though I knew what I needed to know about Ryzen+, but understood that some things was still unexpected.
Got stressed over the rapid temperature spikes, though I did something wrong with the waterblock mounting.
But It seems this is normal based on all the post I have found.

So my understanding from the world of internet is that Ryzen+ do have Precision Boost 2 and XFR, which both are not consider as overclocks.
Precision Boost Overdrive (PBO) is

My main concern are all the conflicting information/opinions about the Vcore, but for manual overclock the main majority consider 1,35-1,4 Vcore as "safe" for all core overclock.
I tried PBO and did not like it. I got quite high voltage spikes 1,55< Vcore and temperatures was also high.
After rewatching der8auer review of this board which I have seen before, I now noticed that he states that "Perfomance enhancer" is XFR and therefore not consider as overclock?
This seems to be stated in the BIOS as well since ASUS only states "(OC)" on level 3 and 4.

So i got really good results on OC2, peaking on 4,340 Ghz on 2 cores. All core loads during Cinebench was hovering around 4,24-4,27 Ghz.
But also peaked 1,525 Vcore one core
I do believe I actually scored lower with PBO and the voltages and temps were higher.

So if Performance Enhancer really is XFR and not overclock, shouldn't I trust somewhat that AMD/ASUS do know what they are doing? I am on a fairly mature BIOS.
The voltage seems to stay around 1,4-1,45 even idle
The Vcore on OC1 are about 0,1V lower.

Wuest3nFuchs Hi ,

i got my 2700x @4GHz with 1.265v if i remember correctly.
Paste in some pics later today.
I also got my WC parts, not all but a few so i could run the 2700x on it.

So far it seems stable but needs more stability tested to be Sure its rockstable.



Did 4x30min on occt, played bfv, pubg, chernobylite.No issues so far,only sometimes windows wont start the audioservice, but i believe its just windows.

Prime95 Tests scheduled for the Weekend.

Hokies83 I was able to get 4.3ghz with 1.45v stable manual OC.

But with PBO and some blk adjustments got 4.4ghz max boost. Will drop under load tho even if it stays under 70C not sure where to go from there.

2700x is a hot power hungry sucker when compared to the 1700x and seems to like temp spikes goes from 43c then 50c then back down then spikes to 50c again.

PBO is bouncing back 1.45v 1.5v which looks scary to me, but if it’s doing it then AMD must think it’s ok.
