Hi!

I am working on a new build with all new components with the MSI Meg x570 Unify and AMD Ryzen 3900X CPU that I just bought.

I am unable to POST, I get this error code 0D with a red EZ debug led on for DRAM. 0D refers to "Reserved for future AMI SEC error codes" so that is not helpful. I do get up to boot code 02 before getting this error.

I have basically tried everything so I am really stock with this same issue. Here is what I have tried:

-Removing all peripherals, storage and GPU. I have unplugged also all the IO front case cables. Still same error.

-Upgrade BIOS to latest 7C35vA6, remove the BIOS battery and press the clear BIOS button. Still same error.

-Tried RAM modules in all different DIMMs slots and tried with a single stick. No luck

My RAM kit is G.Skill Trident Z Neo F4-3200C16D-64GTZN (2x 32GB DDR4-3200)

I found out that this RAM kit is not on MSI QVL for this motherboard but G.Skill says on the other hand that my motherboard is on their QVL. This kit is an optimized RAM kit for X570 chipset so I am really surprised that it is not working out the box on my MSI motherboard. From what I have read so far, XMP must be on to make this RAM works but since I am unable to post I do not have the opportunity to change that in the BIOS. Closest kit on MIS QVL is F4-3200C16D-64GVK but this kit seems to be the same as my kit, expect that it has no RGB led.

I am still now within my window for a quick RMA with NewEgg but I would like to know
  • If we can rule out a faulty CPU. Can a bent pin cause this?
  • Can it just be a RAM incompatibly issue? I have no way to test with other DDR kit. If you can confirm me that this kit is compatible this would avoid me the trouble to sent it back and pay the restocking fee for my mistake of choosing the wrong RAM kit.
  • Can the motherboard be faulty?
I am an experienced IT so you can propose me some things.

Thanks for your help

Your RAM is common enough that it should work. I don't know, MSI is having some quite short QVL lists with some of the new mainboard models, are they slow with verifying all the RAM they have, or what is going on. But normally, this RAM shouldn't pose big problems. Of course, it would still be nice if it were on the QVL. The Trident Z Neo and the Trident Z are not the same modules, they definitely use different PCBs and possibly also ICs. Don't be misled that only the last two to three letters are different, they are still behaving differently.

By the way, you NEVER have to remove the battery on modern mainboards. Either pressing the Clear CMOS button or shorting the Clear CMOS pins will reset everything, just like taking the battery out would do. There is no additional benefit to taking it out.

What's the error code without any RAM installed?

Can you please list your other components?

I have a brand new EVGA G5 750 PSU with a new Ryzen 3900X CPU.

I did not bother to install a decent GPU yet, I did some test first with a working GPU just to be able to get into the BIOS but I quickly took it out when I ran into this 0D error.

Bottom line is that even with the motherboard out of the case with just minimal setup to power on the CPU and motherboard I still get this 0D error. Even without any RAM installed I get that same 0D error.

MIS technical support is clueless. Seems like I am better to RMA this board.

The led for CPU error is off but is there any chance that I could still be the CPU?

This might sound weird, but... from a Reddit post where this helped:

Unplug your monitor's power cable and leave it unplugged for 30 seconds. Plug it back in and then reconnect the display cable.

With or without GPU it does not change anything, led for a faulty RAM is on no matter what. MSI is advising me to go for a RMA, which I did today. I do not want to spend any more time on that board, hopefully a new one will do the trick. I have no way to test my RAM and CPU cause I do not have a spare AM4 board with me. I think the odd that my CPU or RAM are faulty is pretty slim compared to having a bad board. I have seen another post of someone with the same issue and going for an RMA was the thing to do. Thanks for your input. anyway.

What i was suggesting was to disconnect power from the MONITOR, i haven't mentioned the graphics card.

You can read it here (replace XX with tt): hXXps://www.reddit.com/r/Amd/comments/65fhy0/new_ryzen_build_error_0d/dga1hph/

This is an easy one-minute thing to try.

It was a faulty board with bad memory controller. I just received my replacement board today, everything is fine. :)

the board does not have a memory Controller on modern computers that is held in the CPU in its I/O. was probably a bad socket mount or bad Poorly Soldered Joints on the Memory Slots
