The ASUS Pro WS X570-Ace Review: x8x8x8 with No RGB
by Gavin Bonshor on August 12, 2019 9:00 AM ESTBoard Features
The ASUS Pro WS X570-Ace sits in the mid-range of the X570 product stack with a price of $380 and combines professional features such a Realtek RTL8117 Gigabit NIC that offers hardware-level access control for server functions with the ASUS Control Center Express application; this is assisted by an additional Ethernet port controlled by an Intel I211-AT Gigabit NIC. A Realtek ALC1200S HD audio codec handles the onboard audio and includes an EMI shield and is set on a separate area of the PCB. The solid-looking 12+2 phase power delivery includes an elegant and large aluminium heatsink and draws its power from a single 8-pin 12 V ATX CPU power input. Providing power to the rest of the board is a single 24-pin 12 V ATX motherboard power input. One of the standout features comes in the way of the full-length PCIe 4.0 slots which run at x16, x8/x8, and x8/x8/x8.

The solitary U.2 slot supports PCIe 3.0 x4, and the four SATA ports feature support for RAID 0, 1, and 10 arrays.
Test Bed
As per our testing policy, we take a high-end CPU suitable for the motherboard that was released during the socket’s initial launch and equip the system with a suitable amount of memory running at the processor maximum supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.
While we have been able to measure audio performance from previous Z370 motherboards, the task has been made even harder with the roll-out of the Z390 chipset and none of the boards tested so far has played ball. It seems all USB support for Windows 7 is now extinct so until we can find a reliable way of measuring audio performance on Windows 10 or until a workaround can be found, audio testing will have to be done at a later date.

Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things, including better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal) at the expense of heat and temperature. It also gives, in essence, an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency / monitoring priority, overriding memory sub-timings at JEDEC). Processor speed change is part of that risk, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the system build.
New Test Suite: Spectre and Meltdown Hardened
Since the start of our Z390 reviews, we are using an updated OS, updated drivers, and updated software. This is in line with our CPU testing updates, which includes Spectre and Meltdown patches. We are also running the testbed with the new Windows 10 1903 update for AMD's Ryzen 3000 series CPUs, and X570 motherboard reviews. The Windows 1903 update improves multi-core and multi-thread performance on AMD's Ryzen processors with topology awareness meaning previous issues in regards to latency have been known to affect performance. As users are recommended to keep their Windows 10 operating system updates, our performance data is reflected with the 1903 update.

It seems a great mb and it has a wonderful look. It is not the board for me, I'd go HEDT with an Atx board, but I like the approach based on quality, caring about details that do not shine on paper or on images but they shine on performance, reliability and why not pleasure to use. The shield and separation for the audio it is a needed touch of design elegance.I really hope this is not the last we heard from x570 boards, to me the x570 offer lacks an outstanding pro oriented Itx board.

I saw comments that 3900x works very hot (high temperature). On this asus board is it possible to configure processor downclock, like lowering the cpu voltage? I will use for full load processing for more than 24 hours in a row.TheinsanegamerN - Thursday, August 22, 2019 - link
The 3900x is a 12 core CPU. It's goona need some big boy cooling. If you dont want to deal with the heat you should probably stick with an 8 core ryzen. You could turn off turbo boost, but then why bother shelling out more for the big chips if youre just gonna kneecap it?abufrejoval - Thursday, August 15, 2019 - link
As much as I like the 3x8 general option, it pains me that the first logical addition to a GPU and perhaps a RAID controller, 10GBase-T Ethernet is going to swallow 8 lanes of PCIe 4, while a single lane would be quite sufficient and actually the Ethernet IP block for that is already supposed to be inside the 'chipset'! And that price, whatever licence cost required to make use of it, should be included.Otherwise it looks like one of the sanest mainboard designs I have seen so far.

"One of the key elements to this board design is the x8/x8/x8 PCIe 4.0 slot layout. This motherboard is the only one on the market that uses a full PCIe 4.0 x8 lane available from the AMD X570 chipset, enabling an array of different use cases that ASUS believes this market needs. Technically the upstream link to the CPU is still limited to PCIe 4.0 x4, however this does enable PCIe 3.0 x8 cards to have full bandwidth, which accounts for a lot of add in cards (RAID, high-end networking)."This is quite possibly one of the worst boards on the market then.
They have three PCIe 4.0 x16 physical slots, but either only run at its native x16 speeds if you only have one card installed, x8 if you have two, and really x8/x8/**x4** if you have three cards installed since the chipset to CPU interface is a PCIe 4.0 **x4** link.
That is so dumb.
Why would they bother putting in a x16 physical slot, and then because of the chipset link, only run it at x4 electrically?
Quite possibly one of the worst product development/engineering decisions ever.
A single NVMe PCIe 4.0 x4 SSD would be able to consume all of that bandwidth.
moriz - Friday, August 16, 2019 - link
i think the key here is that the third slot can *supposedly run at PCIe **3.0** x8, which allows it to give full bandwidth to any PCIe 3.0 x8 add-in card.*supposedly, because i've yet to see any confirmation that it is capable of doing the PCIe version switch.

hey! , I bought this mobo a couple of days ago, I bought it because I wanted to upgrade my old cpu to R9 3900X, I also happened to have 4 R9 390 gpus (2 390s 2 390x) , sadly I don't have the cpu yet, I do have the r5 1400 lying around but I don't feel like taking it out from completely different cpu and adding it into that costly mobo just to test things out,I bought that mobo exactly to run 4way CFX with these gpus, 8x 8x 4+4x* & 4x from m.2 to pcie adapter,
based on your words, in theory the 3rd slot should be able to use more bandwidth than a simple 4x 3.0 , is that correct? if so then that will pretty good upgrade over a simple 4x.
anyways just to give you some info, a simple 4x 3.0 uses around 70~75% power of R9 390, while 8x around 99% ,
I do know that because atm i'm sitting through 8x 8x 4x in asus z170-a , which also have m.2 at x4 so 4way is possible as well but I bought the adapter just recently and I don't really want to sit through sata ssd, as well as this mobo currently have problems with 2 ram slots because of which I can't use dual channel atm, which obviously makes 3gpus to barely outperform a single gpu so adding 4th on top of that is pointless, wish the prices on r9 3900x will fall soon.
here is stock 3way (8x 8x 4x) 3dmark (firestrike ultra) score in dual channel when I still had it, also, R9 390X performing with stream processors of R9 390's if I got it right(aka it's like 3x of R9 390 even when some of them have X's), because I was forced to use R9 390 as gpu1 to enable CFX,, https://www.3dmark.com/fs/18192586

How does this even works? Is there some kind of translation between PCIe 4.0 x4 to PCIe 3.0 x8. I dont get it. I thought this was not possible.JKJK - Friday, August 16, 2019 - link
A card like this without 10GbE is completely idiotic.You shouldn't have to waste a pci-e port on it. And it should be intel. Let the gamers use the unstable Aquantica shit chips and drivers (been there, done that).

All I hear about is the chipset fan. I have read (Buildazoid in May 2019 Gig Master review) that it is the RAID setups going through the Chipset that sets the fan off. Unfortunately the second M.2 is only PCIe x2. Other than SATA drives maxed at 6gbs, it does not make sense to run RAIDO for speed. Samsung will have PCIe 4.0 NVMe M.2 that surpase 7gbs R/W within a year and the 2x will not take advantage of that.A deal breaker for me, (I really like this board, really want to order it - looks great and no RGB!)
