ASRock Rack X570D4U Socket AM4/ AMD X570/ DDR4/ SATA3&USB 3.2/ Micro-ATX Server Motherboard

- Came with a new enough BIOS to support 3rd gen Ryzen CPUs out of the box. - Has a wonderfully useful IPMI (out of band management) system that has already saved my butt multiple times by allowing me to remotely manage the server. - Supports IO/MMU, ACS, Virtualization, and all those other enterprise-grade goodies that make running Virtual Machines so much better. I'm currently using Hyper-V on Windows Server 2019, running 6 VM's. One of those VMs has GPU passthrough using DDA for my Plex server for hardware based transcoding. It's working beautifully with a Quadro M2000. Asrock Rack support has been excellent - they helped me fix an issue with PCIe Passthrough not working due to a BIOS problem. They even sent me a beta bios (v3.33) to fix my issue ahead of the scheduled release. All in all, for a 'prosumer' board this is working excellently and meets all my needs.

I'm using the AsRock Rack X470D4U in my home NAS. It's working with ECC. IPMI functionality is great to have at this affordable price point! I'll definitely look at another AsRock Rack motherboard for my next update.

I will preface by saying that I run Unraid on this motherboard with a few Windows VMs (XP and Win10) and several docker containers 24/7, and it has been a very stable motherboard for me now for about 6 months. That said, this review will be presented entirely via the lens of an Unraid server deployment and may not be relevant for everyone. THE GOOD Obviously, finding server management features in this form factor pretty much leaves you looking at this motherboard or nothing at all. I took the dive on an "open box" offering here some months ago, and it arrived well packaged and with all relevant documentation. The operating manual is workable, though it lacks critical details in many areas (especially BIOS menu descriptions) and was clearly translated out of Chinese by a non-native speaker. Par for the course and I do not dock them a star for this. The machine booted to POST on the first try, and I was greeted by an extensive BIOS, to say the least. This was my first experience with a BIOS intended for server management outside of Dell rack servers, and I was blown away with the controls and options afforded me. I can honestly say, as a tinkerer, that I have maybe touched 5% of the options here. The potential is staggering. Fan management, DIMM voltage regulation, idle power draw, hardware monitoring, remote security features, and literally dozens of other menus with which I am still completely unfamiliar. A proper power user has much to gain from the options within the BIOS. In the mATX form factor, it is good to have 4x DIMM slots, 2x full length PCIe slots (more on this later), and a 4x PCIe slot, as well as 2x M.2 slots, 8x SATA ports, TONS of fan headers, and more miscellaneous pinned headers at the foot than I know what to do with. This board could service a full tower of parts, and again is a little staggering in versatility. This board draws power efficiently, idling with a GTX 1660 super, 4x enterprise SAS hard drives, 2x NVME drives, 2x SSDs, a Ryzen 5 1600, 2x fans, and a AIO CPU cooler at a mere 40 watts. Its chipset handles heat well: I have seen 0 meaningful throttling at hot-but-not-alarming temperatures. Onboard diagnostics, BIOS flashing, firmware reset buttons, and more. This board really does offer features that are genuinely unique in this form factor for this chipset with this socket. Amazing innovation and market awareness by ASRock. THE BAD Ok, so this board is not perfect. I will start with what I believe to be a design flaw that I currently suffer through, but that may be a deal breaker for many prospect buyers. There is a fundamental and inherent layout and power delivery design incompatibility: you have three PCIe lanes that fight for space and electronics, and there are no ideal configurations to maximize the potential of this board. First, the layout. From top down ASRock included a 16x, a 4x, and another 16x physical set of PCIe slots. This should be great news for enthusiasts: on paper you have room for a modern graphics card, a sound card to account for the lack of onboard audio, and another expansion slot for things like more USB headers or in my case a SAS controller. Life should be good right? WRONG. In spite of their clearly being room for the 4x slot positioned ABOVE the primary 16x slot, ASRock instead chose to sandwich the 4x slot between the two 16x slots. This means that if you use a dual-slot graphics card, you can necessarily never use the 4x slot. Second, the electronics. The primary and secondary PCIe slots share 16x worth of lanes. This is absurd! If you have anything plugged into the second 16x slot, all 8x of its power is robbed from the primary 16x slot, and not from the 4x where you might expect. This means that you have to choose between your GPU getting its full bandwidth and power OR running an expansion card on the secondary physical 16x lane and having both cards operate at 8x power. This is a massive flaw in my opinion, even if it only affects some users. I cannot think of a good reason why the lanes are allocated like this rather than isolating the primary 16x lane and netting a little extra power to split 12x across the remaining slots. Remember how the first 16x slot blocks the 4x slot with a dual slot graphics card? That's right, you will ALWAYS leave 4x worth of power and bandwidth on the table and when you try to use the secondary 16x physical slot, you will feel that loss. Why ASRock could not have segregated the primary lane is a huge question mark for me with this board. The moment you insert a full size GPU into a build with this board, you are inherently hamstringing the effective net power of the machine because of PCIe design mismanagement. The above is especially true and underscored by the fact that this board does not have onboard audio. Again, this is a niche requirement as far as workstation boards go and I get that, but ASRock historically being a company of the common man should have seen this issue from miles away way back in the development stage: if you want to game online with voice communication (hi it's 2020 and everyone needs voice communication in their machines), you have to choose between serial based voice communication protocols (rather than analog) OR powering your GPU with the 16x lanes for which those products were developed. Other than PCIe lane design, I do not have anything negative to say about this board. I would prefer to have seen even a single USB 2.0 header on the board somewhere, especially on the IO panel, but that does not cause me major heartburn. THE CONCLUSION I recommend this board. I really do. I sing its praises from mountaintop to mountaintop. But deep down in my heart of hearts, I know it could be so, so much better. I hope ASRock is developing a successor board that address these issues. For Unraid users looking to work with AMD in a small form factor (or any form factor, really), with true server features, BUY THIS BOARD.

This server board is very well built and has all the features I need: - onboard video - 2 x Gigabit Ethernet - remote management over (industry standard) IPMI protocol - up to 128GB of ECC memory, and - enough PCIe 3.0 lanes for two dedicated RAID controllers, or 1 x dedicated RAID Controller + 1 GPU, or 2 x GPUs and integrated SATA RAID controller w M.2 SSD for a storage. The above usage scenario still leaves me with one available open-ended PCIe x4 slot for expansion, which is not bad at all. Populated with 64GB of fast 3200MT/s ECC DDR4 (Kingston p/n# KSM32ED8/32ME), 8C/16T Processor (Ryzen 7 2700), + Adaptec RAID Controller with it’s own dedicated DDR cache memory and SSD cach for hot data provides me with a balanced system. The dedicated RAID offloads the processor, so my system is well positioned to run multiple virtual machines. With regards to Base-band Management Controller: if you are not familiar with how NC-SI (Network Controller Side-band interface) works – you need to be patient and know how to setup the network to take advantage of the IPMI. Depending on your level of qualification the learning curve can be steep. Many people jump to conclusion and express their frustration in their reviews – mostly due to luck of understanding. I have since overcome every obstacle I encountered with the motherboard. This is a server board, take your time, and know what you are doing. The UEFI / BIOS The number of available UEFI BIOS options to tweak various Ryzen power envelope, performance, processor L1 cache, and memory controller is extensive. I mean really, really extensive, so be prepared to study all the BIOS settings – it will take time. Being the server, this motherboard (expectedly) does NOT support XMP/AMP profiles, so to use the high speed memory you must manually configure it in the UEFI BIOS. There are options to fine tune DRAM timings, or pick the desired memory speed from the from the list. AMD processor virtualization option in the UEFI BIOS is enabled by default. One thing I would like to add, is most of my bad experience with the board was due to my misunderstanding of the Management controller side band interface. My experience contacting Asrock Rack for support was a pleasant surprise. William at Asrock Rack was very helpful and had sent me the updated version of the BIOS within few days of reporting the issue. The only one thing to be improved is the slow firmware release cycle which was already mentioned in other reviews. P.S. I'm not affiliated with Asrock Rack and have nothing to gain by posting my experience. The bottom line is that every problem I encountered with this board, was due to my own false expectations, or luck of understanding of the server features of this board. The only one thing I wish I had done, was to reach out to Asrock for support earlier rather than later. Three month since making a purchase I can say this board worth every dollar I paid.
