Did you also try removing the CR2032 battery for about 10 min or did you perform a CSMOS reset by jumper/switch?
I had one unit (just RMA’d it a short time ago) where such a thing also happened and (external) reflashing the BIOS and BMC flash chip helped.
I finally rma’d it since it corrupted the BIOS/BMC images every few weeks.
Have another unit that has been operating reliably hardware-wise within the limitations of the buggy firmware since last July.
@aBav.Normie-Pleb Would you go with these boards again despite all the issues if you need another motherboard?
Yes, since I’ve decided to move away from Intel if possible and there is still no other AM4 board with proper IPMI remote control on the market (I don’t consider the ASUS Pro WS X570-Ace to have proper IPMI remote control).
Also, I enjoy having ECC and Intel’s Xeon prices are still shitty and you don’t know how many mitigation patches are going to pile on top of each other in the future that are further reducing their performance.
Maybe with Milan there’s going to be a wider range of motherboards from more “seasoned” manufacturers/BIOS developers that are more usable for a homelab situation.
Really sucks we dont get more options
Noop.
I have FreeNAS 11.3-U1 installed and it becomes unresponive every 24 hours or so… while troubleshooting the issue I discovered an oddity with the date/time in the IPMI settings. The time seems to randomly adjust itself by some random amount (most frequently to UTC). I’ve tried changing the NTP servers, completely turning off auto-update date/time, and everything in between. The BIOS date/time matches what shows in the IPMI when it changes. No other settings in the BIOS/IPMI change so I feel like it shouldn’t be the CMOS battery.
Any ideas?
I’m using an NTP server in the local network that seems to work - did you try this or are you using one of the many public NTP servers on the internet?
So I’ve been looking at these for a long time. . Finally decided to purchase a 1600AF. Was just going to use a b450/x470 board to save a couple of bucks but most of them have some type of limitation. Been leaning more towards this board.
My use case is for Unraid. Would love to have ipmi but it’s not absolutely necessary. Server will be in my basement. Don’t really plan on using Plex, but maybe. Just want NAS and some Dockers and VMs.
My question is this. After reading all the issues in this thread where do we stand with everything? What still does/doesn’t work? Trying to decide between one of these or maybe a x470 taichi (in case I want to switch it to a gaming PC later on to replace my 5820k).
An another questions, where were you lucky to get one of these boards in EU? I see Scan.co.uk for a ridiculous price and a bit better price at Lambda-Tek.com, but that is all I could find and both offers are out of stock.
Another thing I was thinking about, what about VRM temperatures? From photos it looks…subpar.
Also, was memory support (maximum frequency when running 4 sticks of RAM) improved with time and BIOS revisions?
After these new findings, I brought Asrock Rack in contact with AMD US (because AMD TW wasn’t helping them). I didn’t get an update yet since then… I’ll post it once I get something worth posting 
Can anybody confirm that the the X470D4U’s backplate is glued to the motherboard?!
Finally got my second unit back from the retailer RMA process and wanted to test the low-profile Noctua heatsink with a 3700X.
Unscrewed the four srews securing the two heatsink brackets but the backplate doesn’t move a bit. When looking closely you can see some “goo” between the backplate and the PCB.
Is this normal?!
Edit: Yes, the entire surface of the backplate is covered with double-sided sticky tape.
Heated the board to about 60°C for ten minutes, then I could wedge a plastic spudger between the PCB and the backplate and slowly lift the backplate from the PCB.
Are all AM4 backplates like this? Was my first time removing a non-Intel backplate.
@aBav.Normie-Pleb On my unit it is not glued. After unscrewing the plastic brackets it just falls off. But sometimes I wish it was glued (when installing a bigger cooler), so I guess someone made a decision to do it.
@droptheghost I got mine from germany (jacob[dot]de) but it seems that it is no longer available there.
You could try contacting Asrock at ASRockRack_sales[at]asrockrack[dot]com
I was trying to get my hands on this board last year and they replied with a pretty accurate date when asked for EU availability. Contacting ‘official’ distributors on the other hand was less than useless - one rep didn’t even know that they are on the AsrockRack reseller list.
Separate post since this is about a different topic: ECC reporting - it seems like a lot of people are interested in this.
My board seems sort of faulty and I can get some ECC errors on demand. If I remember correctly someone of FreeNAS forum reported something similar.
When using a specific DIMM slot with auto timings/frequencies I get this sort of cache errors in dmesg:

There is nothing in IPMI Event Logs.
Changing the default frequency to something different in the OC menu (lower or higher) fixes the errors so I guess this is some memory training issue on my board.
What is interesting is that I see no errors when I disable ECC in the BIOS. (checked using memtest86 and memtester)
I send the board for RMA to the seller, got it back with a note saying that no issues was found. I got ghosted on any further questions about their testing.
Wrote to Asrock support, got new BIOS to try, few things to check but when I asked about a possibility of getting a replacement on the grounds of those ECC erros I got the same response that was pasted here a few times:
- AM4 support ECC function
- AM4 does not support ECC error reporting function
So with this I guess that indeed the regular ECC reports that I would expect to appear in IPMI logs on any Intel server board do not work. But it’s not all doom and gloom - at least single-bit errors are reported in syslogs and can be acted upon.
Hi, thanks for your detailed report.
So it seems like the ECC reporting issue we discussed is concerned only 3rd gen CPUs, there are several users got functional ECC reporting with 2nd gen CPUs.
Still waiting on ASRock to release 1.0.0.4B Agesa. They are taking their time.
This is something I noticed when I looked into how to replace the headsink on my X10SDV. It’s also using doublesided tape on the backplate
Am I interpreting data from Memtest incorrectly or is board actually dangerous and puts any data in a big risk of corruption?
STH is going to be releasing a review on these motherboards soon.
I’d expect a very detailed review with a totally helpful score of 9.7
Well that is helpful, that means it’s better than Breaking Bad for example.
