Yes. I'm using a Core i5-13500 in mine and ECC is active.

All the Core i3/i5/i7/i9 CPUs support ECC. Intel artificially limit it to the workstation and server chipsets (like the W680) just for product differentiation - they need reasons for people to pay more for higher-end chipsets.

AMD take a different approach and let motherboard manufacturers enable it for Ryzen CPUs, but only officially test/validate it for Epyc (server) and Threadripper (workstation) CPUs.

So I received this board and attempting to first update ME via the ipmi before I update bios.

I plugged just the power to the motherboard 24 pin and 8 pin connector but my ipmi card does not light up at all. I plugged the Ethernet cable into it and the port does not light up, when I plug the cable into the motherboard Ethernet ports they both light up.

The motherboard just displays “00” on the screen, I can’t get the ipmi card to do anything. I even tried plugging a 6 pin power connector to the ipmi card and nothing happens.

Am I missing something?

I don't know how many DIMMs you're using, but I'd suggest trying to boot with just one to help rule out any RAM compatibility or slot issues. Also, for me it took around five minutes to do the initial memory training. Be patient on those first boots. Good luck, it's a great board once everything is up and running.

Did you plug in the IPMI to the internal USB header? That is where it gets power from when the computer is off. The 6-pin is just for additional power for fans.

Also, I believe you can only do an update to the ME firmware from within windows on this board.

For the latest me update I had to create a bootable USB with windows and the me drivers installed in order to run the update.

I ended up using WinToUSB https://www.easyuefi.com/wintousb/ (note not an endorsement as there are other ways to get windows installed on a usb drive)

It works from WinPE, so you can use something like Hiren's BootCD PE or Sergei Strelec's WinPE. Essentially a bootable Windows image with a bunch of useful tools preinstalled.

1) I was able to access ipmi and changed default password. Once I did that it says invalid password and won’t let me log in.

Use ipmitool (on Linux) to reset the password. https://www.intel.com/content/www/us/en/support/articles/000055688/server-products.html

Does your USB drive work for booting on a different computer? It might be the USB drive that has issues.

Ok so apparently my usb died during all of this, didn’t even show up in the boot menu. I took it out and stuck it in my laptop and my laptop doesn’t even see anything connected. I tried on several different computers and it wouldn’t read at all.

Thankfully I make daily backups and copy them to an external server just in case my flash drive dies. I downloaded my backup and created a new usb and now unraid is running finally.

I still haven’t tackled ipmi yet, can I run ipmitool on windows or can I do it within unraid?

Follow up, restored unraid backup to new flash drive. It was recognized by MB and I was able to finally boot into unraid.

igpu is detected and shows up in plex, my lsi 9300-16i hba card showed up and all drives were detected without issue. I have 12 16tb drives and added 2 more which were recognized and are now pre-clearing.

Ipmi password was also reset and I can now log into webui. All sensors are reading except for my rear exhaust and front intake fans which are connected to my nexus+2 hub of fractal define 7xl case, the hub connects to cha_fan2. I will try just bypassing hub and connecting directly to fan header.

Thanks for all the help everyone, this system is a lot snappier now and everything loads much quicker!

I’m am experiencing an issue with the bios, whenever I power off system and do a power drain by holding the power button, all my settings in bios are reverted. The battery is firmly in place and I even replaced it but this issue still persists.

I should also add that the time/date don’t reset, only my settings like multi monitor and fast boot.

Huh, so i'm not the only one that happens to! interesting.

For me, it's if I turn it off and pull the power plug; it'll typically lose all those settings.

Yes that’s exactly what I did and all settings revert which is very annoying. So anytime I have to completely cut power to it I have to go back in and apply all my bios setting again.

But what’s weird is that the internal bios clock does not reset, so clearly the cmos battery is working. What else could cause this? I plan on calling Asus tomorrow to find out if there is an issue with the board or what might cause this. I don’t expect much of a response but we’ll see.

Edited September 3, 2025Sep 3 by Android_18

So I called Asus and as expected they were no help. I specifically told them that the bios clock doesn’t reset, only settings that I manually set. They said they knew what the problem was and that I need to replace the cmos battery which I already did.

Then they said to send the board in so they can take a look, I’d rather just exchange the board from where I purchased it then wait 3+ weeks for them to receive my board and send it back.

Does anyone else have this issue?

I may be failing in my search-fu today but not finding a clear answer: is anyone managing higher than c3 with ipmi installed?

I am on 4101 bios as 4302 was reported to have issues with c states. Onboard Ethernet disabled. I found one USB device preventing even c3, removed for now. 5x Ultrastar 16tb hdd. 2x mx500 sata SSD, 1xm.2 980pro, x710da2 nic (DAC to switch)... Can't break a mean of 35w idle. Triple checked bios settings, have the Intel GPU drivers installed. Really don't want extended down time chasing things unless it's not ipmi for sure.

In hardware breakin testing I was hitting 22w without the GPU drivers, 1x onboard Ethernet, and with a different m.2 and only 2 SSD, no hdd. I didnt pay enough attention as it idled where I expected to be so didn't chase it, should have tested further there I guess.

@melorin83 Could you elaborate how you connected the HDDs to the mainboard? Are you using the SlimSAS or the standart sata ports? Or do you have an HBA?

I tested my Asus W860 Ace with this configuration the last days (no IPMI):
Intel Core I5-13500T
64GB DDR5 ECC
2x NVME
4x SATA
BIOS 4101

My findings:
Using the inbuild LAN locks the board for me to C3.
Using my own 2.5G card in any PCIE slot instead gets me to C6.
Using only the bottom M.2 Slots and no PCIE card gets me to C8.
Using the top M.2 Slot drops me again to C6.

I activated all relevant ASPM settings, disabled audio/bluetooth/serial port and activated ALPM as well as setting the C state limit manually to C10.

C6 is fine tbh, but now comes the caveat: Connecting ANY of my ssds to the native sata slots drops me to C2 (tried Samsung SM863a, 850 Evo as well as Micron 5100 Ecos). I am currently lacking a SlimSAS cable so I cant test these ports. As a reference, I could hit with the same configuration of hardware C6 without problems on a Asus Z790M-Plus, so there seems something to be off with the SATA controller in this board.

Guys, is it a bad idea to use mixed ECC RAM in this MOBO?

1-1 piece of the following ones:

I've got a very similar combination in mine - can't remember the exact model numbers, but I have 2 x 32GB Kingston server ECC 4800MT/s and 2 x 32GB Kingston server ECC 5600MT/s for 128GB total. They're mismatched because when I upgraded from 64GB to 128GB a while back, the 5600MT/s RAM was the same price I paid for the 4800 a year earlier.

It works totally fine, and runs at the lowest speed (so if you have both 4800 and 5600 RAM, it'll run at 4800).

You may need to manually set the RAM speed in the BIOS if it's not automatically detected. The first boot with the mixed RAM may take a minute or two before Unraid starts, while it trains the RAM.

I am effectively using all slots on the ATX and all NVMe and all sata ports populated (using a slimsas breakout cable), IPMI in the 1x slot, HBA in the x16 slot configured for x16, SATA card in an x4 slot and 10gb NIc in the other X4.

So seems like none of the lanes are shared between NVMe and the slots, just bifurcation being used for the X16 slot.

Are you using heat sinks for the m.2 drives on the board? If so do they get close to the PCIe cards?

I plan on adding 2 more m.2 drives to the board but only the very top slot has a heat sink built in, the rest would just slot in without heat sinks. I would like to use a heat sink if it wouldn’t hit the PCIe cards.

Feels like this is the only place talking about this motherboard, but does anyone have any tips to get 4x48GB sticks stable on this motherboard? I'm running an i5-14600K, and the motherboard underclocks to 4200MHz from 4800MHz, which in my usage so far has been unstable with random freezes. I dropped it down to 3000MHz and I still experienced a freeze and am trying 2400MHz. Curious if I should be doing anything else like messing with voltages to get this working.

The sticks I got are from a generic brand on a eBay, so maybe that has something to do with it, but I think they ran fine when I used only two sticks.

I know this is everyone's first step and you've probably done it, but since you didn't mention it in your post, did you run at least one full test with Memtest?

Is it ECC or non-ECC? If it's ECC then you should be able to see any error correction/detection in the syslog. If you see a lot then the memory is probably faulty. In either case, try run Memtest overnight and see if it shows any errors.

I wouldn't trust generic brands from eBay. It's possible they're using poor-quality RAM chips that failed QA and were rejected by another brand. What's the brand on the RAM chips themselves?

Have you tried them in a different computer?

I did one full pass on a single stick, and then two sticks for one night, but I can try again. I've also tried a full pass on all 4 sticks at some point, and that seemed okay.

They're ECC sticks. For what it's worth, I got the sticks from a merchant called Mem-Store on eBay, and they seemed pretty reputable, or so I'm led to believe. I checked over the syslog and they usually don't print anything prior to the system getting hard locked/frozen until I have to hard reset it. I've had the log print realtime as well, and I usually never see anything get printed prior on my monitor. I've had the system similarly lock up during MemTest a couple of times. I'll avoid linking the item page here, but these are the specs:

48GB 1x48GB DDR5-4800MHz PC5-38400 288pin 1.1V 2Rx8 ECC UDIMM RAM Memory Upgrade

When I tried only two of the sticks, I think the system didn't have any issues, but maybe I didn't run it long enough for the issues to surface. Right now, I have the RAM underclocked to 2133MHz and set the VDD/VDDQ voltages to 1.2V (the latter being a total shot in the dark). Currently transferring files from my old NAS to this new build, so I'll know when the thing freezes up again, if isn't stable.

Another note, I'm outside of the return window, so I'm desperately trying to make these 4 sticks work, otherwise, they'll just be wasted PCB bricks and I'll be out of a pretty penny, to say the least. Definitely should've done my research a bit more on DDR5 but didn't think to since my old build with DDR4 was just a smooth process from beginning to end. Shucks.

Edited November 27, 2025Nov 27 by AHSMB

So you say they passed Memtest, but also that they locked up on Memtest?

Which is it?

If they're locking up, that's pointing to the problem...

If you're running them at their rated speed or less then clearly points to faulty RAM.

Can you figure out which stick(s) are bad? It's a time consuming process but the best way is to hammer them with Memtest for a while

Yeah, I can try running memtest again. Honestly, can't remember what's what anymore with the memtests I ran a few days back.

Edit: Forgot to answer the brand question, but I'm not quite sure. MemTest itself is reporting the sticks as unknown, so yeah.
