QCODE (Q Code) 53 on ROG Maximus Z790 Hero

Level 9

There have been a bunch of posts about this but no real answer and I'm almost 100% sure this is software related (BIOS) but ROG is just telling me to RMA the board, which I don't really want to do given all the other threads with the same issue.


PROBLEM: Typically during reboots after any kind of update (Video card, windows, whatever), my POST will hang with a Q CODE 53 and orange light. I have to do a hard power off and then restart to get it to POST again, which forces a BIOS visit where all settings are fine and then restarts normally from there. I have run two different memory modules with the same result. I am on the newest BIOS and controller. I have tried all XMP profiles as well as AUTO. I can't get ASUS/ROG to actually troubleshoot with me outside of just "RMA the board".

Has anyone had any luck fixing this? It works perfectly and runs smoothly except for this issue, so while a nuisance, it's not really enough for me to want to take apart my entire build to most likely get another motherboard that will do the same exact thing.

MOBO: ROG Maximus Z790 HERO (1202 BIOS with updated controller per instructions on BIOS update)

PROC: i9-13900K

MEMORY: Have tried both G.SKILL Trident Z5 RGB Series 64GB (2 x 32GB) 288-Pin PC RAM DDR5 6400 (PC5 51200) Desktop Memory Model F5-6400J3239G32GX2-TZ5RS as well as TEAMGROUP T-Force Delta RGB DDR5 Ram 32GB (2x16GB) 6400MHz PC5-51200 CL40 Desktop Memory Module Ram for 600 700 Series Chipset XMP 3.0 Ready White - FF4D532G6400HC40BDC01 (IT ERRORS ON BOTH MEMORY SETS)

Graphics: RTX 4080


I was wrong, still the same issue, lol.   

Hi! Just delete completely Armoury Crate trought special software.

Hi RaiBinger,

Do you mean remove Armoury Crate and use G.Skill Software instead? If yes, I have already done so, but I still hope ASUS could fix this bug.

I would keep trying after every new BIOS released until it is fixed.

Thank you for the suggestion!

Wtf is this bug ? I tryed many times to restart my computer and for now it’s ok i don’t have any error code but if you have bug is this G-skill ram the problem?

Hi Superavageur,

After surveying threads about this issue, I think it has nothing to do with RAM brand... 

I used two different approved ram brands, same issue

I got same problem and I want to solve it. 

Asus Rog Hero Z790 Maximus and G Skill DDR5 Trident Z5 RGB 64GB (2x32GB) 6400 CL32. 


As I have noticed, the RAM backlight hangs in freezes or starts stuttering if I turn on Armoury Crate or SignalRGB to control the whole pc's backlight. Also RAM STOPS being visible in ARMOURY CRATE, CPU - Z, HWMonitor, but shows up in Task Manager as if everything is normal. When trying to reboot the PC, it hangs and gives Q code 53. The only thing that helps is to turn off the power supply and turn the PC back on.

I removed ASUS AURA SYNC LIGHTING SERVICE from autostart and then the PC lit up with default backlighting, not tied to any software. In this case, no Q code 53 errors for 3 days.

I too thought the problem was in the bios and so I updated all versions sequentially and it didn't help.

Has removing Armoury Crate helped anyone with this problem?

Kkkanyonnn i try to droped the frequency to 6000 mhz and for now i solved my problem. You can try this solution but i ´m sure the problem is the bios.

Did You delete Armoury Crate from your pc and it didn't help?
