ASUS Maximus Hero Z690 error QCODE 55 blue screen

Motherboard: Asus z690 Hero Rog Maximus DDR5
Processor: i9 12900k
Memory: corsair vengeance 2x16 5600Mhz ddr5 cl36 cmk32gx5m2b5600c36
Cooler: corsair icue h150i pro xt hydro series 360mm
1 M2 Nvme ssd 500 gb wd sn770 gen4x4 (here are windows and programs)
2 SSD 240 Gb Kingston a400 (steam and epic games)
Power supply: corsair rm1000x 1000w
Video card: galaxy rtx 3080 sg
windows 11 pro x64bits
Case: Redragon Demolisher

The RAM configuration since I assembled the PC is DIMM_A2 and DIMM_B2 according to the manufacturer's manual.

The PC had been in use for about 1 year and 6 months with XMP II active without problems until 07/15/2024 when it gave a blue screen with a memory management error and then the Q-CODE LED showed error 55 and it would not start. After removing the memory from the DIMM_A2 slot, the PC turned on and error 55 no longer appeared on the Q-CODE LED. In the tests I did, I noticed that if I used the memory in the primary DIMM_A2 and DIMM_B2 slots, the PC gave a blue screen. If I used the DIMM_B1 and DIMM_B2 slots, it did not give a blue screen, or if I used only DIMM_B2, it also did not give a blue screen. Now, if I used any of the DIMM_A1 or DIMM_A2 slots, it gave a blue screen.

The blue screen error keeps alternating between memory_management KERNEL_SECURITY_CHECK_FAILURE, DRIVER_OVERRAN_STACK_BUFFER and SYSTEM_SERVICE_EXCEPTION

I have already tested other XPG brand memories and it keeps giving me a blue screen.

I have updated all BIOS units, video units, etc...

I have already checked the processor socket, the pins are all ok

I visually checked the motherboard and there is nothing damaged

I installed Windows on another SSD and it keeps giving me a blue screen

I disabled and enabled XMP

I restored the BIOS to factory default

I used IPDT_Installer_4.1.9.41_64bit.msi to test the processor and everything is OK

In short, the PC starts normally without problems, only with one memory in slot B2. Using slot A2 and B2 it starts normally but keeps giving blue screen and you should get error 55.

Hi @joaohd based on what you have shared, it seems either your CPU or your board has gone bad. You would need either some friend or local repair shop to confirm which of these devices are giving you trouble. Or if you have a spare board as another machine to test it yourself and rule out the hardware that can gone bad. Then you can see if you can get a replacement under warranty or you may need to buy it new.

Since you only have 2 RAM modules, you can just use them in B1 and B2 and continue to work with slightly slower performance too.

Maybe someone else here have better ideas than me and either help your rule out the device giving problem or may even give you a solution without any replacements. Good luck!

Hello @joaohd 

On Intel platform motherboards, if the system hangs on Q-code 55 during boot, it may indicate a memory issue.
Kindly refer to [Motherboard] Common Q-CODE(Error CODE) and Troubleshooting if needed.

Could you please clarify if BSOD and Q-code 55 occurred following any recent changes, such as a Windows update or replacing memory modules?
May I ask if your current BIOS version is 3802?
Have you cleared CMOS and attempted to boot into the system with the default BIOS settings without enabling any XMP memory overclocking or applying any manual settings after updating the BIOS, but the BSOD or Q-code 55 still occurred?
If installing a single memory module in the DIMM_A2 slot also results in a BSOD or Q-code 55, we recommend you try the following steps for a bare-board test:
Remove the chassis, install only the CPU on the motherboard and use integrated graphics for video output, a single RAM module in the DIMM_A2 slot, and the PSU to further verify if the system still encounters Q-code 55 and fails to boot.

Thank you.

As the local holiday is ongoing, there may be further delays in responses.
We appreciate your patience in advance.
