BTW, I have the same symptom with a biostar J4125 mobo. So I guess that makes biostar as good as erying…?

Out of curiosity (and my biostar mobo being so shitty), I bought the 12500H-itx one.
While I haven’t booted it yet, I’m already pleasantly surprised!
- While they don’t have a manual - pretty much every connector on it is properly marked, easy to understand.
- Even the M.2 slots are marked with gen and bus width, sata supported or not (all 3 don’t support sata)
- Did I say they even have debug LEDs to know the boot process?
- (how do I use the “UART” and “DEBUG_CON”? I’m pretty sure they’ll tell me if I asked)
- They’ve definitely iterated their CPU heat spreader.
- Unlike the one from the video (I forgot witch), the backplate now doesn’t expand to the cooler mount. Any stock cooler should fit.
- The screws on the backplate have a spring washer now (not fully compressed) - maybe they’re using torque drivers to assemble now?
- Their customer support on ali isn’t afraid to say “I’ll ask the engineers, give me some time” - that’s very refreshing after dealing with larger mobo companies!
- BIOS updates? biostar doesn’t have it either, so there’s that.
Anyone interested using this mobo and a M.2 → 8x sata card? One can make a janky 16 drives Server/NAS out of this, or 8 drives with the other M.2 converted to PCIex4 for a DTX chassis.

They have some damned good engineers over there in the other direction (“over there” is usually the USA). Sure, parts and solutions are probably borrowed (copied) from large manufacturer, but they also offer on site support and don’t ask you to download a file from a Russian forum. (Just an example.) I would be surprised if the larger manufacturer don’t look at a mobile cpu solution now, and Intel are worried people will buy something else than their most expensive cpus. This would not have happened if it wasn’t for these guys.

I really want supermicro or Asrock Rack to come up with a similar solution. (Ideally still with IPMI)
Those server mobos are the only ones that I can think of having better IO than this - especially with all the off label things we can do with M.2 slots.

Yeah. I mean, if they added ECC support on their xeon motherboards that would be the gold standard for nases. Unfortunately it seems like Erying don’t have any plans for that at this point.
Found this yesterday. m.2 to firewire

Yeah, that thing has got its own graveyard. please don’t dig it out.

Hi, I’m trying to make the same changes as you but I’m having some problems. Have you managed to unlock c-state and aspm on the ITX version with 12th gen cores? Can you give me some tips or possibly pass me the modified bios? Thank you
Hello,
I need help, please…
Changing the bios is a big mystery for me, but I’m looking to unlock overcklocking on an Erying Itx motherboard with a 12900hk.
I tried to understand the tutorials but did not understand anything.
One of you would have the possibility to communicate a modified bios for this motherboard?
Or an easy way to unlock these menus?
That would be great!
Thank you very much and congratulations to those who know how to modify…
Which cooler pattern do these generally use? LGA1700 or LGA115x/1200?
115x
I picked up one of the 13900H ITX D5 Erying motherboards. LGA1700 mounting holes.
Seems OK, a bit buggy posting sometimes.
Power limit fully adjustable no problems. No SA or VDIMM voltage adjustment, XMP voltages apply. 5600 max DRAM speed, some timings are adjustable and it seems to keep the XMP VDIMM when using custom timings.
Was 24 hour Karhu mem test stable with 64GB 5600 C36-38-38-something.
Undervolting is locked (BIOS settings for undervolting also do not work).
IccMax is limited to 160A (ends up being somewhere around 120-130W ish max according to HWINFO)
Was able to update Intel ME firmware to 16.1.27.2176.
Was able to update CPU microcode, RST VMD module, RST OROM no problems.
Password protection of Runtime Variables is enabled (write protect in RU and setup_var).
I THINK the 2230 CNVi slot may be only a CNVi slot, although, I only have BE200’s on hand, I do have an AX210 and an AX411 on the way.
CPU IHS isnt fantastic, I did a real quick half assed lapping after testing and it was worse than any CPU or heatsink I ever lapped, BUT before lapping I was not thermal throttling anyway on a test bench with a 120mm AIO and maxed out power limits BUT it was power limited by IccMax.
Tried editing the BIOS with UEFI editor and once with AMIBCP , just ended up with a brick every time OR nothing actually changing (eg no undervolt, no setup_var writing, no extra menus, no IccMax changes), I am a noob to be fair, gave up after 5 CH341a flashes.
I don’t want to mess with the bios anymore at this stage, would love to increase IccMax mainly, undervolting would be nice but it doesn’t really bother me.
Main VRM is a Richtek RT3624BE & 6 Vishay SIC654 (50A), no VRM temp shown in HWINFO.
So there’s a few settings you need to change to unlock undervolting stuff probably at least it was like that on my erying 11th gen
Just thought i would post a bit of an updated.
Not sure what I was doing wrong, probably lack of sleep and poor health BUT, I was able to increase power limit/current limit, get up to 140Wish now, not a huge difference but it increased my AVX stress test power limits by almost 20W in some situations.
I believe “PSYS PMax Power” and “VccIn Aux Icc Max” were the main limiters .
In other systems I have removed power limits, it was just VR current limit and TDC limits or TDC enable. I just went ham and maxed out everything i could find but no difference until the above two were changed.
Ring/uncore seems limited to 4.0GHz with the iGPU enabled and seems to clock up to 4.5GHz with the iGPU disabled. HWINFO flags “RING: Max VR Voltage, ICCmax, PL4” constantly, doesnt seem to be actually impacting performance or throttling, perhaps the caps are due to core voltage or some other design? i dunno.
AIDA lists the standard max ring frequency as 4.7GHz
Anyway, still no undervolting but you can adjust AC loadlines with an unmodified bios.
5600 max memory speed, the hidden option with speeds above 5600 do nothing, might be able to adjust memory related voltages in the hidden menus but its a bit broken and the voltage adjustments i tried caused a no boot or no post, even just upping the voltage to the next step without changing anything else.
While memory timing settings exist in the unmodified bios, they dont all work or might not work as expected.
There are 3 main menus or forms supressed in the bios, those three should give access to all anyone could ever want.
I removed the supressions and was able to access them by “shutdown /r /fw /t 0” as, by default, this causes the wrong “main” uefi page to load which includes a bunch more info…
It is kind of buggy but it works good enough for me, press esc at the first page of the UEFI then select the second duplicate option of “advanced” or “chipset” etc, need to reboot in between as when you esc from one of those, it loads the stock main page without the duplicates.
And while the 13th gen ITX board does use LGA1700, the Z hight seems to be lower.
I had an old Corsair AIO with a Phanteks AIO mount work but be pretty loose and a Cooler Master AIO not even make contact at all. Both are LGA 1700 specific coolers or mounts. I was able to use the Corsair LGA1700 standoffs with the Cooler Master AIO to fix the issue. (Currently have the board in the NR200P Max, hence mentioning the Cooler Master AIO)
And yes, the CNVi WiFi slot is only CNVi, AX411 works fine. You do not get the metal bracket/mount with the board. I just got an “ASUS WiFi Go” and fit an AX411 inside it.

I haven’t seen these mentioned as much but if you can make do with only 128GB non-ecc ram and one x16 and one x1 PCIe 4.0 these Xeon W-11955M based motherboards from Erying is a pretty nice alternative. The latest non-Xeon are max 96GB and before that it was 64GB.
