Had 0d errors with this board before, but persistence and rebooting (after dumping current/power button held for 30 seconds) usually won out. Today I got a new Lian Li case, Lian Li fans, and 32 GB RAM (GSkill Trident Z RGB, 3200). Needless to say, much excite/wahwahweewah.
Upon powering on the PC, I don't even get a post. It goes straight to error code C5 for a few seconds, then switches to the all too familiar 0d.
I've tried holding the Reset CMOS button in the back, specifically holding it down for 5-10 seconds, but that doesn't change anything.
This couldn't be a BIOS issue, right?
Do I try and RMA/Warranty the board with MSI or go back to BH Photo (got it from them last November)?
Is there another option?
Sincerely desperate,

Just spent 8 hours building and got an error code C5 on the motherboard. The PC then power cycles. Anyone ever have a similar issue? There is not much to find when trying to search for it.

Hey everyone, I need some help with an issue I’m facing. I recently installed a Ryzen 7 9800X3D into my MPG X870E motherboard, but every time I try to boot, I get error code C5 on the motherboard. I’ve checked the manual but couldn’t find any information on this error. The CPU and RAM debug LEDs are both lit up, so I’ve already checked both components, but the problem persists. Does anyone have any ideas or suggestions on what might be causing this? Appreciate any help!
Salut, je viens de monter un nouveau PC pour la première fois. J'ai les composants pertinents suivants :
MSI MAG X870E Tomahawk
Ryzen 9950X3D
Kingston Fury Beast 64GB DDR-6000 CL30-36-36 (c'est officiellement compatible avec la carte mère)
Quand j'ai démarré pour la première fois, j'ai eu une erreur "C5", ce qui indique un problème de RAM. J'ai donc testé différentes combinaisons. Les deux modules de RAM fonctionnent lorsqu'ils sont utilisés seuls en A2, mais dès que j'ajoute l'autre en B2 (ou n'importe quel autre slot), j'ai à nouveau "C5" et je ne peux pas démarrer.
Mettre à jour le BIOS n'ayant pas aidé, j'ai appris que de tels problèmes peuvent être causés par le CPU ou le socket du CPU. Avant de monter le PC, j'avais testé comment je devais mettre le CPU dans son socket. Même si je pensais l'avoir fait attentivement, le socket avait 2-3 connecteurs tordus après avoir retiré le CPU. J'ai remis ces connecteurs en forme (du moins, je le pensais) et je ne m'attendais pas à d'autres problèmes.
Bref, le socket n'avait pas l'air aussi abîmé que ceux que j'ai vus sur des photos de gens avec des problèmes similaires. Qu'est-ce que tu me conseillerais dans ma situation ? Démonter les composants et jeter un autre coup d'œil au socket ? J'hésite parce que je ne veux pas risquer d'autres dommages, à moins que je doive vraiment le faire. Si oui, devrais-je essayer de trouver un pote avec un CPU compatible et voir si ça marche sur ma carte mère ? Ou tester mon CPU ailleurs ?
L'installation de Windows 11 avec un seul module de RAM de 32 Go a réussi et les premiers benchmarks semblent bons. Penses-tu que j'aurais des problèmes supplémentaires à l'avenir si je décidais de faire tourner le système avec seulement 32 Go au lieu de devoir acheter une nouvelle carte mère (CPU ?) tout de suite ?
Merci d'avance pour toute aide !
Just assembled my rig. Keep getting C5 on the 7 segment display, red and amber CPU/dram diagnostic LEDs.
Every ram slot throws the C5 code except A2, both sticks work. I can get to the bios with one stick, but as soon as one stick goes on B2, whether it's both or one, it throws the C5 code and stops.
Suggestions? On the last beta bios, not the most recent one.
I just mounted all the parts for my new PC, plugged the HDMI cable for the screen then the USB for the keyboard to start installing Linux from the bios and then I got… code 15 for about 30 seconds, then it remained stuck at code C5 and nothing is shown on the screen.
My components are:
Motherboard = ASUS ROG Crosshair X670E Hero
CPU = AMD Ryzen 9 7950X3D
Power supply = Corsair, RMe Serie RM750e
RAM = G.Skill Trident Z5 RGB
Storage = WD black SN850X 2TB
GPU = MSI RTX4060Ti Ventus 3X 16GB OC GeForce 3xDP
I was careful to:
place my 2 RAM sticks on A2 and B2, that doesn’t change a thing.
I also tried to put only one RAM on A2 but wasn't luckier.
Then I tried:
upgrading the bios using the USB key to 1905
Reverted to 1904
Emptied the cache
Removed both RAM and got code 10, but still nothing on the screen (which I assume is normal as the PC can go to the POST stage without RAM) Any idea what went wrong..? This is my first PC build and i have no idea of what to do now.
[EDIT: SOLVED] It appears that the RAM seemed properly plugged in (I had heard the click and the lights were turning on) - but I had to force more the bottom part of the RAM stick into the MOB.
