Black screen at startup: VGA-led and 0d error code

Hi folks,
I was very happy to upgrade my old motherboard today from an ASUS P7P550-E LX to a brand new MSI MEG X570 Unify.
As a result, I have bought new RAM modules and a new CPU (see specs below).
The new setup seemed to be fine. Everything seems compatible, all cables are in the correct positions, and the PC powers on.
However, I start up with a black screen with no apparent output to my monitor with two red flags:
  1. The VGA-LED in the EZ debug area is lit
  2. There is a "0d" error code displayed on the debug hexadecimal screen
I have scoured the internet of all possible solutions I could find. Here is what I have tried:
  • Re-seating the GPU
  • Swapping the two VGA cables connected to the GPU and double checking connections at both ends
  • Using only one RAM module and trying each of the four DIMM slots individually (while checking to see that it was fully inserted each time)
  • Flashing the BIOS, including removing the CMOS battery for 10 minutes before reinserting
What's also a bit weird is that, while from what I gather from the error code the GPU isn't being detected, that the GPU fans are running with and without its VGA power cables connected. And, interestingly, the GPU is one of the only components I did not replace when purchasing a new motherboard.
I have attached images of what the motherboard looks like while the PC is running with these issues.
My specs are below:
Motherboard: MSI MEG X570 Unify
CPU: AMD Ryzen 5 3600 3.6GHz
GPU: NVIDIA GeForce GTX 960
RAM: Corsair Vengeance RGB Pro 32GB 3200MHz DDR4
Power supply: 650W

to me that is the board is not liking your Gigabyte Graphics card at all as they tend to have VBIOS 's on them that do not play well on other makers Motherboards especially MSI. could you get a hold of another brands Graphics card to try that is not made by them?

Thanks for the response!
This sounds very reasonable. Unfortunately, I do not have another brand of graphics card off-hand to try.
If it comes to it, what would be a good brand compatible with MSI motherboards?

couple things you could try
1. press numlock and see if the keyboard indicator goes on/off (check if system really hangs)
2. try different PCIe slot (i remember gtx960 has problem with ryzen 1000/2000 CPU when it's in PCIe slot 1, not sure if it can happen to your case)
3. try different HDMI cable

anything other then Gigabyte. they are well know compatibility problems on MSI Hardware where everyone else is not.

Thanks, plutomate.
  1. Forgot to add this on the original post! Numlock and capslock both do not have an indicator light.
  2. I was hoping to avoid this potential solution as I have to modify the inside of the case so it will fit. I have just done this, tried booting, same problem after all!
  3. Just given this a try, no results.

What's strange is that I have re-checked the compatibility of Gigabyte Windforce graphics cards on pcpartpicker.com and have found that there are plenty of other compatible graphics cards excluding the GTX 960 chipset (see image).
Is this a thing?

Did you change your BIOS setup from CSM (the default) to UEFI?
(ie has CSM been disabled?)

No video has been a common problem lately, and it seems to center around
disabling CSM, which some devices apparently still need, such as video cards.

Its OK it won't affect your ability to install Windows as a UEFI OS, but it might not support secure boot.

Hi flyingv,
I haven't even had a chance to enter the BIOS at all since it's a new motherboard.
At this stage, I'm going off badboy2k's suspicion that the GPU is simply having compatibility issues. I have ordered a new GPU which is on an official list of compatible cards for this motherboard. Will update when it arrives in a few days' time.

Some googling and reddit other people suggest that 0d is a DRAM training error.
It would appear that when new (different) modules inserted the motherboard detects this,
retrains, and saves the training data somewhere for reload in the future. Some ppl claim
that clearing the cmos settings will clear the training also, but I am sure you've already tried this.
(One way to know for sure would be to insert a/some different RAM.)

If the new GPU doesn't fix it, then next is probably RAM to look at or sadly the mb itself.

Yeah, this has been a big part of the mystery.
I exhausted the methods in those threads that ruled out the possibility of DRAM training errors which made me focus on the potential GPU issues.
As for different RAM to try, it's a shame that my old RAM is DDR3 and the MSI Unify only accepts DDR4 as far as I have read and tried.
And, to be honest, I'm fairly sick of the whole Gigabyte/MSI compatibility thing. It's something I've definitely seen before and now just feels inevitable. Kind of like the year 2020 in general.

Yes. I understand. Sorry if I missed that in an earlier posting.

I figure any one of us could suddenly experience problems at the next bootup or power on without
any sort of warning or obvious cause. As for the whole G v M thing, what good are standards if
devices don't operate together.

(I also don't think that these problems are unique to MSI. I would imagine every mfr
has their hair on fire chasing the current crop of system issues, especially since they
are all working from the same codebase, it seems.)

No worries - the new GPU is on its way so I'll be reporting back here once I try it out 🤞

New GPU (Sapphire Radeon Pulse RX 5600 XT, 6GB) arrived today, and same results. 0d error code displays as well as the VGA-LED.
No idea what to do now.

How about trying with different GPU power cables?
If still no go, next you might need to test different RAM modules.

The issue has been resolved.
Turns out it had nothing to do with the GPU despite the VGA-LED being lit and the "0d" error message.
Despite previously reseating the CPU previously, I remember that the thermal paste that came with the Ryzen 5 3600 was so adhesive that it was very difficult to separate from the cooler fan. This led to a fairly tricky installation of the CPU onto the motherboard.
I happened to have some different thermal paste, so I removed the original paste with some isopropyl alcohol and replaced it with the paste I had.
After popping the CPU back in, there were suddenly no issues.
My conclusion is that the pins were somehow not fully in contact with the motherboard.
I hope this helps anyone who has this same problem!

If this ever happes again you can use a piece of plastic Coke Bottle larger the bottle the easier and cut out a 3 inch circle use that to slide under the heat sink and CPU to seperate being careful not to touch the pins.

Oh and Nice GPU upgrade Full AMD systems are Back
