Will not boot, displays Q-Code OC

[ItzZebo_JB]

Hello, I tried a soft overclock on my system (Ryzen 7 3700x, ASUS ROG Crosshair viii Hero (Wi-Fi), AMD 5700xt) and it wasn’t something I haven’t tried before. The system shut off and would not boot back up. I tried clearing CMOS, removing the CMOS battery (and in the process I took out the GPU), removing the RAM, And tried booting into safe mode. Nothing has worked. I usually get the same codes 0d and E8 then it’ll change to the code OC on the motherboard with the White VGA led lit up. Anyone have any idea on what to do or what the problem may be? I haven’t taken the CPU out yet.

What do the codes 0d and E8 mean? You should look them up in your motherboard's manual.

 

If no GPU is installed, then the VGA LED will probably light up.

Well 0d means “Reserved for future AMI SEC error codes” and E8 means “S3 resume failed.” I have also gotten 06 which is “Microcode loading” and OE which means “microcode not found.” And the GPU is installed which confuses me. I’ve been looking all the codes up that I get to get an idea, but OC shows up after a minute.

These all seem to be codes that should be resolved by a CMOS reset I would think.

 

Are you sure the CMOS reset you did worked? Did you remove the battery? (Edit.: Oh wait, yes you did.) I know that there are nowadays buttons or at least jumper pins to perform one, but I like to remove the battery entirely and let the PC sit for a minute, while holding down the power button and it beeing disconnected from the wall. Just to make sure.

 

In case you did that, then I think it's time to simply reseat the CPU. Sometimes the most unlogical stuff can help.

 

Also unplug all drives when trying to boot into the UEFI.

Run a bios recovery. If that doesn't repair the issue, RMA the board.

I did take the CMOS battery out and the PC sit a bit with out it in it. But it may be the CPU for some reason. I will also try unplugging the drives from the board as well.

I’ll try the BIOS recovery too. I do feel like it’s CPU or Motherboard related. I had an issue with the USB ports before and USB 2.0 headers

It's bios related. This issue always has been. 

The codes will specify to reseat memory and VGA, clear cmos.... All the things you've tried already.

 

Fingers crossed a flash works. 

If it does not work with the cpu installed, remove the cpu, put a single stick of memory into slot A1.

Thank you for the link! I’m trying this first thing tomorrow since it was on my troubleshooting list. Can you clarify the last statement you made? It’s a little confusing how it’s worded.

You can flash the bios on the board without the cpu installed. If you have an issue flashing the bios while it is installed, then remove it and try the bios flash again.

I’ll give that a try as well. I’m flashing it right now. Hope it’s a quick fix instead of long one. I didn’t know you could flash the BIOS without the CPU installed. Good tip, thank you!
