Yeah, that's a static OC, under 15/16 thread full load using WCG.Is that static, though?
3900x will pull more power than 2700x.
edit: that one leaked review already put the 3700x (65W TDP) at ~120W full load.
They have the VRMs for it, theoretical current limit is 480a on the primary (realistically speaking, you will hit socket/pinout limits before hitting even the functional current limits of the VRMs). Both are T-topology so do not expect elite memory overclocks. HOWEVER if you are going to populate all four DIMM slots, you may be in a better position because of that. ASRock used doublers on both boards so you may see some more vdroop compared to "twinned" configs (Asus) or configs with "true" non-doubled/non-twinned layouts (basically, top two Gigabyte boards). Use common sense and some LLC to mitigate.
You may miss some features you find on Asus boards (PBO tweaking) but that is pretty niche. Also expect the max memclock selectable in UEFI to be DDR4-4000, at least on the X370 Taichi anyway.
Overall, X470 Taichi should be slightly better due to the layout changes that AMD mandated from X370 -> X470. And UEFI support has slowly been getting better for some users of Summit Ridge and Pinnacle Ridge on X370 Taichi. There may be hope in that department. UEFI rev 5.60 on X370 Taichi already supports Matisse. UEFI 3.40 on X470 Taichi does the same. X470 seems to be getting updates more frequently (X470 has had 3.40 available since late May; X370 was updated two days ago). Both are using AGESA Combo-AM4 1.0.0.1

Looking at the MSI Gaming Pro Carbon WIFI:
https://www.overclock.net/forum/13-amd-general/1624051-vrm-new-am4-motherboards.html
Only 4-layer means reduced signal stability for PCIe 4.0. May also limit RAM overclocking. There were some rumours that x570 boards would all have to be 6-layer to handle PCIe 4.0. I do not think that's the case, but still. It's something to consider. If you aren't using any PCIe 4.0 devices and if you do not care about your RAM OC then it may never matter. VRMs are equal to the task, even if they de-rate at higher temperatures.
Is that static, though? Usually a 2700x with PB + XFR tops out at 105-110W, depending on the review. I know my 1800x @ 4.0 GHz pulls over 200W. Heh.
I am talking stock here.
I laid out what I am looking for.
The problem boils down to signal integrity. Motherboard vendors at Computex 2019 told us that motherboard traces, the electrical pathways that carry data signals, require wider spacing with PCIe 4.0 compared to PCIe 3.0. The wider spacing, coupled with the increased power requirements for the PCIe bus, necessitates placing the transmit and receive traces on different layers of the motherboard, whereas PCIe 3.0-capable motherboards can carry the signals on a single PCB layer. That means most new X570 motherboards, and their newer B- and A-series counterparts, will come with a minimum of six layers, while previous-gen motherboards would dip down to four layers. That has obvious cost implications that will manifest as higher pricing on new AM4 motherboards. (Edit: There is word that Gigabyte has a few four-layer boards, we're following up for clarification.)
So am I. PB + XFR is stock. Was on the 2700x, will be on Matisse. Not talking PBO here.
Take a look at the MSI MEG ACE and see if it doesn't meet your criteria (it's 6-layer). Of course it'll be more expensive. Word on mobo layers and proper PCIe 4.0 support:
https://www.tomshardware.com/news/amd-pcie-4.0-socket-am4-motherboard,39559.html
Of note:
There's no telling what chicanery the OEMs may have used to enable PCIe 4.0 to work on 4-layer boards. The lower-tiers of x570 are littered with such designs. I'm wondering what throughput will be like on those boards when running PCIe 4.0 devices.
edit: Hmm, early leaks are suggesting the Ace will be at 414 GBP at launch:

Yech. No telling what they'll charge for it in the states. Maybe you'd be better off just getting the 4-layer board.
I am looking at beefy down draft coolers right now and will probably pick one up in a month or so.
Only with the stock cooler. Put anything else on top and you're no longer running stock.PB + XFR is stock.
It'd be fun experiment to try other 92mm fans to see what kind of performance the stock wraith max could do. There are a few 92 x 25mm deltas that could fit.
I like downdrafts, though it seems they are no longer an appealing product to design, so selection is kinda limited. I find with all the aio and tower coolers, the vrms got shafted.
You mentioned possibly modding the stock amd cooler with a bigger fan, but consider that the oem size fan is likely to have better static pressure. Stock fan on the max is a 92mm cooler master (http://www.relaxedtech.com/reviews/amd/wraith-max-and-wraith-spire-cooler/1)

Of the two people arguing, you seem like the one who needs to relax.Mutha luva, chill the eff out, you are really trying my nerves with all of this.
THE CHIP / BOARD IS GOING TO RUN AT STOCK, IT IS NOT GOING TO BE LIKE THE 9900K AUTO OC DEBACLE!
IF I HAVE A FUGGIN PROBLEM WITH THE BOARD, I WILL DRIVE MY HAPPY A$$ BACK TO DETROIT AND RETURN THE FUGGIN THING!
Srsly, wtf, you want to nitpick X570 BS, start a mobo board thread about it.
Of the two people arguing, you seem like the one who needs to relax.
Do you see his concern, though? Even with the 3700X at stock, it was pulling not 65W (which is the TDP) but rather 100+W.
However, I get your side of things too. If the 5xx board says it can handle Ryzen 3000 series, then it can handle the 3950X, and as a result, pulling 100+W will not be an issue. If it is, like you said, you just return it.
But man... you really come off as the one needing to take a chill pill. I think DrMrLordX has a legitimate concern, though I don't think it'll be a realistic one in the end.
So this is what I was thinking of trying out.
Have you looked at the Dark Rock TF cooler? We just installed one for a client at the shop last week and had a great experience with it, temperatures were excellent for CPU and VRMS.

Interesting ( and it looks really well built), but, I was hoping to spend $30 - $50 for this flavor of cooler; I do have a 280mm CLC I could use if I was going into OC territory.
99%+ of users aren't going to have a GPU that even utilizes the full PCIe 3.0 bandwidth, much less PCIe 4.0.
Nobody gives a flying weasel about seq speeds on mainstream platform. We're still fundamentally bound by random IOPS.PCIe 4.0 NVMe SSDs would be the main concern. You only get four lanes to those, and PCIe 3.0 NVMe drives (well, the good ones) are already saturating those with traffic.

There already is one. Much of what I've posted here, I've posted there (where relevant).
Furthermore, if you'd pay attention to what I've said, the main issue (if anything) with the MSI board you picked out isn't the VRMs at all. It's going to be fine in that department, for the most part. Cooling with a Mugen 5 however may hold you back. At stock.
He isn't exactly using the stock cooler though. Either the stock + 140mm fan or a Scythe Mugen 5.
We also don't know what PCIe 4.0 is going to be like on a 4-layer board. If he wants to be a guinea pig then that's fine by me.
It's a good cooler:
https://www.tweaktown.com/reviews/7444/quiet-dark-rock-tf-top-flow-cpu-cooler-review/index6.html
Within 2C of the NH-d15, and since you want top-down it fits the bill there too. Pity it costs so much. It will outperform the Scythe Mugen 5.
