Got the board finally, but only with 4x16 kingston 2400 ecc. The rest almost remained the same, 3700x and a 480 gb kingston datacenter nvme and 2x16tb ironwolf pros. Building a box to replace my current truenas box (3400g, 16gb non ecc, and 2x6tb wd red).
Want to use proxmox with one ubuntu vm (pihol, max 2 cores, and 2gb ram) and truenas (i keep the 8 cores I think). How much ram should I give to truenas? The 2 ironwolfs will be used only for truenas. Truenas has 2 plugins only transmission and plex. I am thinkning to give 8 cores and 32-48gb (?) ram to truenas.
What do you think?
Thanks

I may be completely stupid here, but I really can't figure out how I'm supposed to power this thing once I got my hands on it :/

Got one of these PSUs: 玄人志向 | KRPW-L4-400W:ATX電源 400W

I can get it to power up into IPMI (and log in to IPMI over the network). It recognizes the CPU (3600) but I can't power up further than that - no video out, no BIOS, no video out over VGA...
AsrockRACK did send me a newer user manual and I connected both ATX4PIN1 (using adapter) and ATX12V2 (12v/ground according to pinout). Do I need to buy a new PSU before trying further or does anyone have any insight on how to hook it up? Or could it be something as silly as RAM incompatability (1xCorsair M471A4G43AB1-CWE 32GB DDR4-3200 SODIMM) - the spec does list other 3200 modules as compatible but not this particular model?

I'll probably send it in for RMA if nothing else comes up.

I've got the Epyc3251 Mainboard but I guess AsrockRack is using the same IPMI on both. So I hope I can help anyway.

What happens when you go to "Power Control", choose Power On and press "Perform Action"?
What happens when you go to "Remote Control" -> "Launch KVM" and press the power button in upper right corner?

@nasi

"Power Control": Retries a couple of times before yielding an error message
KVM: Display stays empty, powering on has no effect
Shorting the power switch pin on the board: CPU fan spins up for a couple of seconds and then stops, full power cycle required to make it happen again.

That's strange.
You've got any other RAM stick to test with? Or try to boot without RAM and see if something changes like the error message.
I'm not sure if this behavior is explainable from a bad PSU. Do you have a lot of other stuff connected like a big harddisk array or GPU which may draw to much power when booting? I can't imagine that your PSU is so bad that it fails when starting just Board+CPU.

Nope, just an NVMe - no other RAM but this one's confirmed to work in another machine. Same with/without either. Looks like I'll have to send it in ;(

i needed to use both the 24pin atx (with the special 24 to 4 pin converter cable) and an 8pin eps before the board would properly power up. I couldn't tell from your psu link if that psu had an 8pin eps cable.

One other thing I had read elsewhere is that it needs a 40a 12v rail on the psu to work. Not sure if that is true or not but might be worth trying another psu to see

I was just about to hit the button to purchase a 33A one to try, so thank you :)

If that is indeed the case it's weird not to be mentioned in any documentation, especially being SFF. I don't suppose you have a link to that conversation?

EDIT: May be the PSU: AsRock Rack X570D4I-2T Mini-ITX Server Motherboard AM4 PGA 1331 X570 AMD Ryzen 3rd Generation Series Processors - Newegg.com

> They use a 24pin to 4 pin motherboard power and you NEED to have a powersupply that can at least do 40 amps on the +12v to make the motherboard boots! that will leave a lot of lower powered SFX/ Flex ATX power supply out, a 850W power-supply can usually supply 70A on +12V, but a 400W can maybe do 30, the lowest I tested are 500W @ 24A+24A and it boots, a 400W 28A on the +12V fails to boot but IPMI is able to run.

This could be it. Which is odd, considering this fellow seems to be fine with 300W PSUs: https://www.reddit.com/r/HomeServer/comments/j7zxc1

A new PSU (Silverstone ST45SF-G, 37A on the +12v) did the trick. But turns out the review I linked was correct on it being picky with RAM as well - memtest is failing with sticks that work fine in other machines and OS install randomly freezes. Fingers crossed that the Nemix RAM I ordered works better, otherwise I have no idea where to possibly source 32GB DDR4 ECC SODIMMs...
