Asus dark hero startup issue ?

Hi all
I have a Asus Crosshair VIII DarkHhero ...with an AMD 5900X , 32gb of Gskils ram

Had a few times over last few months since recieving board where the system wont power on.
You press power switch on case and nothing .
You press power button on motherboard ...nothing ....and its lit up white ...all rgb is working ( on when powered off )
If i turn off PSU and back then power it back on ...system boots fine.
It can then be fine for say 4 weeks ...then happen out the blue again.
Was ok with old motherboard....so only things that have changed is MB and CPU.

Tried reflashing bios back to earlier version ...no different.
Had new graphics card since last time so rules that out.
Tried taking ram sticks out ...no difference.

Seems starnge how can run for weeks without issue ( but dont use it every day )

Im using an EVGA supernova 850W PSU.

Not major issue as all have to do is power off PSU and all good again ...but got to be something wrong.
Asus say sounds like something tripping PSU protection ...will have to try unpluging 24 pin and 8 pin cables next time , then plug back in to see if motherboard or psu .

Any help most appreciated.

Hi Xairoo,
This is on the to do plan and it might take some time.
If the DOA date is close and you have concerns about the issue, please consult the seller and return it.
Thank you.

Hi forum,

I am also experiencing this startup issue on my ROG CROSSHAIR VIII DARK HERO after I exchanged my RTX 2080 TI FE with an EVGA RTX 3080 TI FTW3 ULTRA.

When I shut down the PC at night, It typically won't power on the next day in the evening; I need to switch off the power supply (Corsair AX1200i) and wait until the white led of the on board start button goes dark before the board will power on again.

The only change so far seems to be the replacement of the graphics card, which now has a PCIe4 interface as compared to the PCIe3 of the 2080ti.
I would rule out the power supply, as the PC is working flawlessly once powered on; also the typical power draw of ~700W under load should not be critical.
Before the graphics card replacement, the board worked flawlessly for over a month without any issues.

I am really curious about the root cause of this issue - hopefully ASUS will be able to reproduce and fix.

Hi all,

Having the same exact issue as the OP and others. Runnig 5800X, MSI 3080 Gaming X Trio and Corsair RM1000X. Built my PC a few weeks ago and didn't really notice any issues until a while ago (I rarely power off or put the computer to sleep so this wasn't too apparent).

I'd be hard press to say this is a Ram issue as I have tested on my board with two different sets of ram on the QVL with the same result. Have gone through the recommendations of enabling erp s5, clean bios, etc. Tested each ram stick individually, in different combinations and this made no difference. Also ruled out PSU issue testing with an older corsair CM850.

Only real change before runnig into this bug was updating bios to the latest 3801 from 3302 but downgrading and other bios versions in between didn't remedy the issue either. While I haven't noticed an adverse effect on performance as the system is pretty stable when On I am concerned this may cause further issues down the line. If being left without a working PC for a few weeks wasn't such an inconvenience I would have RMA'd the board already though that seems to be the only option left at this point.

Hi hakai,

I'll try my old 2080 for the next days. I can DOA until 29.10. - way better than RMA. But I guess it's GPU related.
RAM, PSU? That would be strange - but no idea, maybe it's true. People talk a lot when the day is long (we are all experts :cool:).

Perhaps Asus can tell us if this problem appears only to the 3000 series GPUs.

Cheers

Hi Big B,

I replaced my motherboard a few days after I replaced my GPU (from 2080 to 3080).
What PSU do you have? Is it an option to test it again with your 2080?
Tomorrow I'll replace the 3080 with a 2080 (one sold, one kept), will see what happens.

I have read sometimes something about this boot/sleep related to the 3000 series Nvidia cards. Looks like it's really happening.

Cheers

PSU is a Corsair AX1200i (https://www.corsair.com/us/en/Categories/Products/Power-Supply-Units/axi-series-config/p/CP-9020008-...).

I still have the 2080 TI here, so swapping the graphics card back would certainly be possible - the only issue may be to find some time to actually do that 😉

So you also have a very good PSU, that shouldn't be the problem.

I just changed my GPUs and not tomorrow! DOA date is too close.
Replacing it took only a few minutes (if not watercooled or riser card or...).

Will post updates.

Hi hakai,
How often did it occur?(for example: if you start three times a day, once of them is not boot? ) only occurred while cold restart?
May I have the information below?
- the serial number of your motherboard via PM
- the brand and the model name of the CPU and RAM
(Please check the specific model name of RAM such as G.SKILL F4-4400C19D-16GTZSW )
- OS version and the OS build
Thank you.

Hi,

Happens more often than not. It's not so much how often I am able to boot but instead how often am I able to actually set the PC to sleep or to power off without it failiting to do so. If I had to put on number on it I would say that if I tried to put my pc to sleep 5 times yesterday 3 of those it would fail to do so. In the case of setting the PC to sleep it's pretty simple to notice it failed since the ram lights go completely off as well as the power led on the case that's when I have to power cycle to sucessfuly boot once again. Also happens when trying to shut down the PC though not as often maybe 1 out of 3 times).

I am currently away from my PC but these should be the ram model I tested with:
g skill F4-3600C16Q-32GTZN - supported according to Asus QVL
g skill F4-3600C18D-16GTZN - supported according to g skill qvl see: https://www.gskill.com/qvl/165/326/1562840461/F4-3600C18D-16GTZN-Qvl
corsair CMK16GX4M2B3200C16 - a pair i was lent which should also be under the Asus qvl

I did test with a single stick of ram, using just two and in the case of the second g skill set mentioned tested with all 4 slots.

CPU = amd ryzen 7 5800X

I am running Windows 10 Pro version 21H1 build 19043.1288

You don't have a 2000 series Nvidia GPU or any other GPU than a 3080? Looks like you can reproduce this really fast. Perhaps I should try to shutdown my system to force this problem. Sleep problem doesn't appears so often, I think.

Would be great if you can test it too with an other (none 3000) GPU!
