no. pins 11&13 are the power btn connections. after short the board turns ON.
if not = dead motherboard, or something other wrong(CPU,PSU,cables,whatever)
So as I've bought a few of these I changed all the parts to another motherboard and it works with no probsyeah I finally got around to replacing it now.. let's see.
Has the BMC overheating been a thing with this? Never heard of it on any machine before..
happens every time upon boot, I think. This machine's been under work for a while, I set it already once up and then was carrying it to the rack where it started show symptoms.. maybe I should take a look at updating the bios+bmc software, too. Bios says "To be filled by O.E.M." under project name
I updated the bios, no change. Changed the CR2032, no change.Even tried to have a fan blowing to the AST2500 chip
sooo.. clear cmos? I'm kinda out of ideas after that one.bad one. not tested for longer time at seller/fatcory.Even tried to have a fan blowing to the AST2500 chip
Hi.
Need some advice.
After attempt to upgrade bmc firmware via web. bmc went off. atm cant login to it. login page is up webserver works but constantly loading cycle after i enter my credentials or admin user.
bios says BMC communication error.
Updating it via uefi says Cant find flash chip #1
Much appreciate any help or advice to reflash bmc with other methods.
UPDATE
Successfully fixed it with socflash utility for ast2500
Links below. might will help someone sometime.

Go into PBO and set it to the 65w mode. You might need to do it manually. I don't have the values at hand but they are available online
Does this board work with 5950x? What about with x3d versions? I'm thinking whats the best cpu for this..Go into PBO and set it to the 65w mode. You might need to do it manually. I don't have the values at hand but they are available online
best cpu is the one who don't fry the VRM power stages.
i think there is some kind of issue with low power mode, it never crashed under load
i have disabled pstates? and it has been running now for 10hours
bmc error:
ID: 3 VCORE sensor of type voltage logged a BMC Event : Lower Critical - going low(Reading value : 0.00 V And Threshold value : 0.00 V) was asserted

i remember a bug on ASRock boards AM4 Ryzen 2700. after high load they undervolt CPU in idle then.
I had this same issue before I set it to 65w mode. Crash during Idle, I never found a soltion other than setting it to 65w mode. If you do find one please let me know. However, like Rollo was saying the VRM is weak for this CPU.
Update on my previous post on my system's power consumption:
This is a fairly idle home server. I am running Frigate NVR, which keeps the system lightly loaded (and the Coral USB permanently active).
The first week on the 5750G, total system draw averaged about 62 watts.
Since my last post, I tweaked the PBO settings to what should be 45W eco mode. After those changes, average draw is about 57 watts.
When I swapped out the original 5700x for the 5750g, I did notice that the BIOS options changed a bit (as has been observed previously in this thread). With the 5700x, I did have a straightforward "45W ECO Mode" setting, but that does not seem to exist with the 5750g. This is the menu path I went through to tweak the PBO settings with the 5750g:
Is there official AMD documentation on these PBO settings? I just found those values on some random Reddit posts. It would be nice to reference a formal document.
Anyway, I'm pretty happy with this setup, as I think it's a nice balance of compute power versus electric efficiency.
