Asus dark hero startup issue ?

Has anyone here already accepted the offer and had their motherboard replaced/repaired by ASUS?


-Did you get a new or refurbished board? ->If you got a refurbished mainboard, what is the condition of the board?

-Can you see where exactly the board was repaired or what was changed?

-Did you get a replacement mainboard before you sent in the old one or did you have to send in the board and didn't have a mainboard for so long? ->If you didn't get a replacement mainboard, how long did you have to wait for the repaired board.

I'm also experiencing the power issue with the ROG CROSSHAIR VIII DARK HERO (BIOS ver. 4006). I purchased it new through Amazon late January 2022. All of my components are also new. I'm using it with a Seasonic PRIME TX-850 PSU and Ryzen 9 5950x CPU. For me, the desktop does not start up after being off for several days to a week. The lights will be on on the motherboard but it won't start up, even if I use the start button on the motherboard. To get it to turn on, I have to power off the PSU, wait for the motherboard lights to turn off, then power the PSU back on. Only then the desktop will power on. I have another, nearly identical build but with the CROSSHAIR VIII HERO (WiFi) and that one works great. However my build with the ROG CROSSHAIR VIII DARK HERO is having issues powering on.

Now started to get the exact same issue that been increasing in frequency to daily now :(
PC will not power on, have to remove power cord to PSU then wait for the motherboard light to go off etc.
Once the PC is on it works fine.
Built this system in November and it's been working fine for months without issue until recently.
I flashed to the latest (4006) bios yesterday in the hope it would resolve the issue but it occurred again this morning.

Please advise how to resolve this issue?

Asus says, this problem requires a hardware fix.

Asus is currently preparing a replacement solution, they are still working on it.
But a replacement means you'll get a used board with the hardware fix.

Please get in contact with STARRAIN@ROG and tell him your serial number.

Hi all,
I have the same issue as everyone else.

Manufacturer was so kind enough to replace PSU (Corsair RM Series RM850x), CPU (AMD Ryzen 9 5950X), Memory (G.Skill Ripjaws V F4-3600C16Q-64GVKC) and of course the infamous MB "Asus ROG Crosshair VIII Dark Hero" as precaution.

Old MB: Part No: 90MB1760 - M0EAY0 - Check number X5T2 Made in China

New MB: Part No: 90MB1760 - M0EAY0 - Check number 5L5W Made in China

Running since April 4th, 2022 on new MB. Startup issue occurred again today April 24th this morning when the PC wouldn't start. Just terrible!
Are there any members out there that can confirm they don't have any issues? Could be that the majority do have the exact same issue but don't find it important or annoying enough to report :)

Thanks.

It would be REALLY helpful if Asus just came out and stated what the issue is they have identified and how it is fixed?
If it is a hardware issue then just state and help customers with the RMA process!

I bought my motherboard from Scan in the UK and they have accepted a RMA on the condition they can replicate the fault.
It is then covered by a 48hr replacement scheme they run.
As i cannot replicate the fault myself (some days it powers on, some days it don't) there is little hope they will and they state it would need to be sent to Asus for testing which would take 3 to 5 weeks.

As I use the computer daily I cannot afford to be without a PC for 3 to 5 weeks in the hopes it gets fixed :/

I like Asus products, but if this was a £100 motherboard I would truly just throw it in the bin and buy from elsewhere!

Come on Asus, this thread is several months old now and this is one of your premium products that got issues without a resolution......

Agree, was surprised as well, no mentioning of the root cause or if they were able to identify the problem. Don't get me wrong, I love Asus products, but this is pretty ****ty on how they treat their customers/TUF-ROG enthusiasts.
What are the chances that this can be fixed via a BIOS update ? Zero? or should we consider it's indeed a hardware/capacitors failure on the MB?

I tried the following workaround:
Disable the fast boot in BIOS, as I read somewhere it could fix the issue. Actually on my end it got worst, had to turn off and on the PSU on a daily basis :D
I still have to test the ErP S4 + S5 enabled in BIOS as it could solve the boot/startup problems from what I read. Will test and report back, unless someone already did :D

I will probably jinx myself saying this but my Dark Hero has never required me to cycle the PSU power switch to boot. Part number indicates it was made in China, though that does not seem to be a factor for this issue. I bought the mobo from New Egg in January of 2021. First boot was in April 2021. Currently running BIOS 4006.

Asus support got back to me and stated the following (I have removed their name etc):-
Quote
"Hi WildBill,
Do you live in UK?
For motherboard, our tech team have found the solution to fix this issue but we have to do the special repair in our RMA center.
The RMA should be sent by the retailer in most of countries in Europe."

This to me indicates it is a component degrading over time and going out of tolerances causing the issue.
My computer been working fine for months until about 6 weeks ago and the issue is increasing in frequency to support my theory. (no hardware been changed)
Guess it's time to RMA but the 3 to 5 weeks turnaround and getting a refurbed product back is not ideal.

Scan in the UK have a 48hr replacement if they find a fault so I guess I just need to wait for it to fail completely and then get it replaced in a few days.

Kinda annoying but it is what it is......

Let me quote myself:

Asus will send you a refurbished fixed board, then you'll have to return your board. That's how I understood it (PM with STARRAIN@ROG).

But the replacement process is still not ready.

The thing that worries me, even if you get a new MB from the retailer, the exact same issue might occur again ? Happened to me in this particular case.
We need some clarification on which Part/Check Number MB that aren't affected regarding the startup issue, in case the retailer decides to swap the MB for new one.
Otherwise what's the point of swapping the MB if the issue is recurring. :confused:

Exact same issue but with a ROG Crosshair Hero VIII (Wi-Fi). Created a new thread for it since it's a different board https://rog.asus.com/forum/showthrea...i)-post-issues

My system was fine until update from 2502 to 4006 now i have the boot/restart problem. Is it possible to go back to 2502? Why is this just occurring after update BIOS? Why would people be getting swaps?

Just an update from STARRAIN@ROG

Hi Xairoo,
I'm sorry due to the impact of covid-19 epidemic, the replacement work and shipping is postponed, and the discussion of the replacement plan is stopped temporarily. Although the estimated time would be the beginning of June, it is hard to estimate when it would recover so far. However, I will keep you updated if it is early or delayed. If you don't want to wait, please let me know.
Thank you.

ERP S4 + S5 definitely helps.

Not for me. Also, does everyone have issues with restarting as well? If I restart the PC it struggles to post.

This article I came across is very interesting https://www.pcgamer.com/update-your-...or-some-users/

It's more or less OC related for the majority, but it doesn't mean the issues we are facing could be related somehow!

I've been having the same exact issue since last summer when I built my new machine.

- Dark Hero VIII
- Ryzen 5900x
- EVGA 3090 FTW3
- G.SKILL TridentZ RGB Series 64GB F4-3600C14Q-64GTZR
- Corsair HX Series HX1200 ATX

For what it's worth I also have a Cooler Master H500M, which includes a hub controller for RGB. A lot of these posts seem to be pretty similar in terms of hardware.......

Occasionally after shutdown it will just refuse to turn back on until I cycle the PSU. I've also had instances of this occurring even after simply putting the machine into sleep mode. I've also had a couple instances of the CPU mysteriously downclocking itself after leaving the computer alone long enough for it to go idle (after which I'm forced to restart to get it to clock back up).

That's true, I had this issue, and I was running a similar setup.
Dark Hero
Ryzen 5950x
MSI 3090
Corsair 3600 cl14 ram 16x4
Corsair HX1200i

...
Currently swapped Dark Hero with MSI X570S ACE MAX, and the setup is running well with the identical rest of the components, no sleep/startup issues, no hard PSU power cycle required to startup anymore. I wonder if the PSU is the factor here. Since you mentioned that you are using an HX1200. (not HX1200i, but it should be similar, I think)

I just purchased 5800X3D and set up another machine with 5800X3D with the Dark Hero (the one I have this startup issue). The PSU I used there is an EVGA SuperNOVA 1000G3, running an EVGA 3080 ti. Nost sure if I will run into the same issue since the machine just got put together this weekend.

The temperatures are rising and with that, unfortunately, also the wake problem.

I hope Asus will hurry with the replacement program.

Silly me, the same issue occurred.

Dear moderators,

Please stop asking people for specs etc and regurgitating the same information and troubleshooting tips. The issue is with THE BOARD ITSELF. The community has already concluded this, not the PSU, RAM or anything else.

I've always bought high end ASUS boards and recommended them to friends. This unfortunately stops today. Really disappointing that pretty much a year later this has not been addressed by ASUS. A simple RMA clearly isn't the solution as there are still boards in the wild with the exact same issue, you are asking customers to roll the dice and hope they don't get a faulty board. Not the mention the downtime they would have to endure whilst they wait.

PLEASE ESCULATE THE ISSUE TO THE RELEVANT TEAM/ENGINEERS IMMEDIATELY!

I've been dealing with this since the board was released and its FUSTRATING. Only solution is to sacrifice the sleep function which is not ideal.
Every day a new thread on other tech forums opens with people expressing the same symptoms.
It's a shame because the Dark Hero is otherwise a perfect board.

I will also be opening threads elsewhere leading people facing the issue here until either ASUS addresses the problem or a class action is filed.

I'm sorry for all of you, but I think you should expect nothing more from this brand.
Other brands suffered hardware problems and took steps to quickly implement replacements.
Here, only one person is trying to deal with this problem but it only seems like wind...
After making us hang around for more than a year to end up using the COVID excuse again to do nothing (I admire your patience Xairoo).

I really waited until the last moment, hoping like you to see something positive, unfortunately I recently started experiencing repeated BSOD.
Is it due to rising temperatures? or a component on the motherboard that was starting to die? I will probably never know given the silence we face with this brand that snubs us and takes us for idiots in the hope that this affair does not leak out in the mainstream computer media (which is a sad that it hasn't happened yet).

I stop there the spread of my dissatisfaction.
I had no choice but to act quickly, so I replaced this board with an Aorus Master X570S, and what can I say, except that I can finally boot without unplugging/replugging the power supply, that I can take advantage of fast boot, WOL, that temperature sensors and a sound sensor are included which is practical for monitoring the OC, that the XMP profile of my RAM went on the first try, where with ROG I had to tweak the FLK to try to reach a value close to the XMP without crashing everything...

Farewell Asus, shame on you!

Yea looks like Asus has abandoned this issue... not single update on it, no sign of a replacement program, NOTHING.
I will defo avoid Asus products in the future

What brand to go with? I've used asus boards for years and need to replace this crosshair board with something that works.

Good question, I'm looking at EVGA, Asrock and MSI, I never had any issues with Asus MBs before, until now Dark Hero x570 hopefully Asus Repair Center can find the root cause and fix the issue.

I upgraded my bios to 4201 and was able to use my power button after shutting down today. Has anyone else noticed this? I also have not had spontaneous reboots occurring.

No clue to be honest, retailer send the MB to Asus Repair Center for "special" repair the issue is hardware related from what I understand. BIOS upgrade won't resolve the issue, as I asked the question before. However it can improve system stability in your case the spontaneous reboots :)

I too have the same power on problem. So sad to see inaction from Asus on this. Make it right and initiate some sort of recall/exchange for this motherboard. I will definitely stay away from Asus in the future. Shame.

Asus said...

The impact of covid-19 epidemic is longer than estimated, and we still discuss the replacement program with our local team. I'm sorry the estimated time would be delay until the beginning of July. I will keep you updated if it is early or delayed.

---

I don't see the problem. There aren't many customers that know about that program. Okay, maybe there will if the program will be public, no idea.

I am also having the issues described here but with the hero wifi board. Shame that ASUS are doing this to their customer, especially on a high end product. Unfortunately I did not find these posts before I bought the motherboard... So I guess on the chance that asus actually gets this "replacement solution" in place i will get a used refurb board that is likely older than the one I currently have as mine had this issue out of the box. does anyone think we will get answers to what is actually wrong? will this issue affect the life of the board? if so does the fix solve that? why are they being so tight lipped about what the issue/fix is? do yall think that the life of the board will be affected fixed or not and this is why they are not being open about the issue? or maybe that the fix involves them disabling/tweaking some function of the board and they know that is unacceptable?

whatever the case something shady is going on it seems. If they continue to refuse to offer an acceptable solution and stall for time what is the re-course we have for dealing with it? I have been posting about this to all the large youtube channels in hopes that they will put some pressure on asus for their unacceptable "replacement solution".

For me, the startup issue is gone after applying bios 4201
The "sudden death" issue (blank screen, q-code led "00" and yellow dram q-led on) is still there.

No it wouldnt solve it, it is a hardware defect, no bios update can fix it.
Just keep trying the issue will re-occur.
It helps to let the PC run maybe a game or something for 30 min and then try until it occurs.

Correct, that was even confirmed to me by the technical/DEV team, they have found the issue on my MB. but i have no replacement yet they need more time.

Did they say any more details about it ? Is this something that will eventually brick the motherboard? Or will it just have this behaviour without getting worse

at least you guys can power cycle and start the pc up

i cannot start the pc up, not from case power button nor the button on the mobo

power cycle the psu does not work, ram, aio rgb on, start button on the mobo is lit, but both the ROG rgb near the io shield and the chipset asus eye logo dont light up

The big question:

Does this problem appear on every board? Or is this random? And has this been fixed for newer production dates?
So getting a new board from the retailer could fix this or not.

Would be great to know.

No he says only, that they have found the issue on my motherboard, and i need a new, but i have my broken MB still, i wait for a exchange, they have only analyzed the bios Profiles from me, and have found the issue.
