ASRock Rack E3C252D4U-2T (OEM/new?) stuck at POST code 00, shuts off after ~10-20 seconds - Xeon E-2324G (used) - exhausted all ideas send help

I have no issues with a lazy system.

This will be my home server running light workloads and mostly idle. I know it is overkill but it is also a hobby (and i stick to server boards only). I am not obsessed with low power states. It's just nice to have.

It burns around 30 watts currently (60 with my llm 3090 slotted in). I can live with that. A 10w difference is roughly 1 euro. Not a problem.

I am just tinkering.

30W sounds amazing honestly.
My E3C252D4U-2T / Xeon E-2374G / 6x HGST SAS (6TB) in RAIDZ2 / 2x Intel S3710 as mirrored app pool / Dell J7TNV HBA330, all on TrueNAS SCALE idles around 80W I'm running Jellyfin, Immich, Nextcloud, and some other self-hosted stuff. Does that sound like a lot given the hardware?

Honestly? Yes and no.

My old x10sll-f nas with 6 sata drives, 4 ssds (2 boot + 2 apps), 32 GB DDR3 was burning 50-60 from wall.

SAS drives consume more, DDR4 too and 10 gigs eat the rest and it's ok if this asrock rack board consumes more

30watts was the past. It's now 54 after slotting in a 3090 for llm :-D

Hello msameer, is the 5.07 firmware motherboard‑specific? I mean, does it vary across different motherboards? I've been considering whether to upgrade the BMC and BIOS, as I'm worried about losing the MAC addresses of the network cards.

I doubt it is specific for my motherboard. I did not send them my board serial number so it should work for you (provided you have the same model).

After flashing the BMC firmware and BIOS, do you have to restore/reprogram the NIC's MAC address?

I successfully flashed the MBC and BIOS firmware. I used the Instant Flash tool in the BIOS interface to flash the BIOS firmware. I once tried flashing the BIOS in the BMC interface, but it stayed stuck at the 100% uploading screen. I actually flashed the BMC from the PVE terminal; you need to give the tool permissions with chmod +x socflash_x64, and then just./socflash_x64 if=E3C252D4U-2T_3.02.00.ima. After it completes, restart the machine, followed by a long wait. There is no need to do anything extra.

Hi MSameer,
I found a problem. I tweaked the temperature vs. fan speed curve in the BMC, but it's not working. The AI check says the motherboard has hardcoded Curve 0, which we can't see. For this curve, the lowest temperature of 60°C maps to a 35% fan speed. Can you check if it's the same on your motherboard?

afaik you need to create a new profile, edit default does not work.

Then i put back my Asrock TR-KNLMB motherboard i had similar issues. I counted mounting holes on the motherboard and inside the pc case and in case there more metal things to mount then there was on board. I matched motherboard holes so none metal screws touch the motherboard and it and it worked. From what you write in first page looks like motherboard shorting on something inside the case.

Wonder if you fixed your issues. AsrockRack Europe always sends last latest bios they have even if motherboard EOL.

Hi RolloZ170,
Thank you for the suggestion, I figured it out. I just need to set a custom temperature in either open-loop or closed-loop control, and then change the corresponding fan's control method to the custom mode instead of the default mode I had selected previously.

I bought a Supermicro ATX power supply, model PWS-1K25P-PQ, that comes with SMBus support. ASRock's IPMI reads the standard PSU address of 0x58, but the Supermicro PSU's address is 0x3C. I built a custom address translation board myself and successfully got the motherboard to recognize the PSU. The translator chip I used is the LTC4316. This power supply is massive overkill for my system's power needs, but it was the only ATX PSU with SMBus that I could find.
