Hi everyone!

Today I received an older PC from a friend of mine. I picked it up, he showed me that the PC was working and then I took it with me in the car. When I arrived home, I connected it to a monitor but it didn't display anything. The motherboard displayed a Qcode 0d. When I start the PC, it starts with Qcode 3f and quickly switches to 0d, where it stays.

Relevant software and hardware I am using: Motherboard: ASUS ROG Crosshair VII Hero (WiFi) Video card: Geforce GTX 1660 ti armor 6g oc Processor: AMD Ryzen 7 2700x eight-core processor Hard drive: Samsung ssd 860 qvo 1tb RAM: Corsair DDR4 Vengeance LPX 16GB (1x) Power supply: Corsair RM750x

I have already found and tried some things on the internet. The conclusion was that it often was either the RAM or the motherboard. What I have tried:

• Putting the RAM in other slots. When I received it, it was in slot B1 and it worked there. I tried the three other slots.

• Trying my own PC's RAM in the slots.

• Trying my own PC's dual RAMs in slots A1-B1 & A2-B2.

Conclusion -> the RAM is not broken.

• Verified that no cables were loose or pins were bent. This was not the case except for the pins of the USB 3.0 ports of the case. Without these, the PC should still start, right?

Conclusion -> all cables are properly connected, the graphics card and power supply both work in my PC.

• Verified that my CPU is compatible with the motherboard -> it is stated on the Asus website that this is the case.

• Verified that my RAM is compatible with the motherboard -> this was not stated on the Asus website as far as I could see.

• Flashed the bios using a USB stick, reset the CMOS and used the reset button on the motherboard.

My conclusion so far is that it is either the combination of the RAM and the motherboard or the motherboard is defective. The strange thing is that it still worked at my friend's place. Could it be that something went wrong in the car or did I do something very stupid when I connected it?

Are there any other solutions? How can I verify that this is indeed the correct conclusion and what would be the logical next step? Buying a new motherboard?

I'm curious about your thoughts.

Well I tell you that my pc was normal, and was running perfect. now it does not come out of that error (0d) that I have read and read and there is nothing right in that error there are many unknowns. I would like you to help me solve this little problem ....

This error randomly occurs on both my old B650 Aorus Elite AX Ice board and now my new X870 Aorus Elite Ice board. I never have issues booting into Windows or while using it, but when I restart I sometimes get a black screen and the 0d debug error with the DRAM light lit. I'm on the latest BIOS and I double checked that my RAM is seated properly. I have no BIOS changes other than Expo 1 being enabled. My RAM kit is F5-6000J3036F16GX2-TZ5NRW.

Has anybody experienced this or know how to possibly fix this? It's driving me insane.

EDIT: This appears to be a hardware monitoring issue. Make sure if you use L-Connect 3 that you are on at least version 2.0.26.

Hi everyone,

when I start my PC my motherboard (the MSI MAG X870 Tomahawk WIFI) shows the error code "0d" and is stuck there, i.e. the PC does not boot. The EZ debug light shows red light for "CPU" and yellow light for "DRAM". Some fans spin (CPU cooler, two fans and GPU fans), while some fans do not. I already waited over 10 min but the PC is stuck.

I contacted MSI support because of this issue and they told me that I should update to the newest bios (7E51v1A24), enable Memory Context Restore and update AMD chipset driver. I did so, but the error still persists! It even got worse: In previous bios version I was able to boot when I restarted the PC 2-5 times, now it seems the PC is stuck in code "0d"!

One important thing to note: The PC ran very stable before. I activated EXPO and it worked perfectly, except of those weird "0d" error code that randomly occurs when restarting / starting the PC. So there's no chance there are some bent pins or RAM incompatibility.

Here is my setup:
CPU: AMD Ryzen 7 9700X
RAM: G.Skill Flare X5 schwarz DIMM Kit 32GB, DDR5-6000, CL30-38-38-96
MB: MSI MAG X870 Tomahawk WIFI
PSU: be quiet! Pure Power 12 M 750W ATX 3.1
GPU: RTX 3060
Current BIOS: 7E51v1A24

I paid over 300 EUR for this motherboard and yet it does not work! How can MSI be satisfied handling customer in such a disrespectful way.

Thanks for helping me out.
Best regards

EDIT (June 2025): The G.Skill RAM that I bought were not on the QVL list. Sometimes it worked, sometimes not. I bought new RAM from the QVL (Kingston Fury Beast 6000CL30 KF560C30BBEK2-32) and now everything works perfectly with EXPO enabled. Lesson learnt: Buy RAM from the QVL to be 100% sure. I apologize to MSI, the MB is great now.

Hello! I just installed Ryzen 9 5900X 12 core 3.7 GHz into my build and its now giving me a 0d code :/

Before I installed that I had a Ryzen 7 2700X 8 core 3.7 GHz... The error code 0d means "Reserved for future AMI SEC error codes" Whenever I boot up the PC it just powers up at max fan speed with the lights on but none of the monitors work and after about 30 seconds it turns itself off..

The only other thing ive done is tried resetting the BIOS but that didnt fix anything :/ Im not sure if this is a motherboard issue but I figured id ask people who are more tech savy then me for help.
