Two things immediately pop out to me: To support the 9900KF P0 you need at least BIOS P1.90, to support the 9900KF R0 you need BIOS P4.0. If your BIOS version is too low you'll have to use a supported CPU to update it first. Table . It could just be the light, but there seems to be a streak of different looking pins in the socket. Are those pins shaped exactly like the rest? It looks like they may have been flattened. Answer from computix on reddit.com

r/techsupport on Reddit: Dr Debug 00, powering on but won't post
July 12, 2019 -

I've been putting together a computer for the first time today, and I've ran into a big issue. My motherboard is a z390 taichi from asrock, and my cpu is a 9900kf. When powering on, the fans spin, the watercooler starts pumping, and the lights turn on, but doesn't post and spits out the error code 00 on Dr Debug.

According to the motherboard manual, 00 means a cpu problem, and advises to check the cpu and reset the cmos. I've taken the cpu out and put it back in twice, it can't possibly be wrongly installed. The arrow is lined up, and its very snug over the socket. I've just been taking the cmos battery out every time to reset it, so it can't be that.

I'm reusing storage drives from my old, prebuilt computer, that ran on a gigabyte made x370 chipset. I don't really understand drivers and the software side, but is that possibly the problem? It has windows 10, but gigabyte drivers for an amd board, and I'm not sure if that would be a problem.

I've plugged the cpu power cable in and out of the motherboard, no luck. I put the powercable in a different cpu socket on my psu, still no luck. I'm at a loss for what I fucked up here.

No POST, dr. debug code 00
Took it up to the bench and just tested it a few times (after removing the HDD, you never know) it would sometimes boot but most of the time not do anything except for showing cod 00 on the dr. debug LCD thing. I looked the code up in the manual of my mobo, it says "unused code". More on forum.level1techs.com

ASTROCK X670-E TAICHI CARRARA STUCK AT 00 DR DEBUG / POST CODE
no cooler, no ram, expects anything to happen?!??! hope you didnt fry the thing. so since you flashed some bioses, are you sure you did it correctly? did you use the pins for cmos clear? did you remove the psu power chord? did you try with only one stick of ram? are you sure that are the right 8 pin connectors of the psu to the cpu? Looks like one is a pci power cable More on reddit.com

Troubleshooting ASRock Error Code 00 and No Display Issues
If the PSU isn’t providing stable power, it could lead to component failures and issues like code 00. 4. **Clear CMOS Again**: After removing the faulty GPU, clear the CMOS once more. This resets the BIOS settings to default, which is often necessary after hardware changes or failures. 5. **Check for Short Circuits**: Ensure there are no short circuits on the motherboard. This can occur if a component like a GPU fails dramatically.

The most commonly seen debug error codes on ASRock motherboards, and how to fix them
February 28, 2024 - Unlike other motherboards made by brands like Asus and MSI, the ASRock boards feature this LED towards the bottom, and it's typically found next to the fan headers or the power or reset buttons. Remember that Dr. Debug LED is just a fancy name given by ASRock to the error code LED, and this LED is different from the regular LED that shows POST codes on other motherboards of other brands.

r/ASRock on Reddit: ASTROCK X670-E TAICHI CARRARA STUCK AT 00 DR DEBUG / POST CODE
August 27, 2023 -

I'm trying to build a new PC, bought all new parts. I choose an Asrock X670-E Taichi Carrara as my motherboard, but the PC will not start and it shows code 00 on DR. Debug. Never worked, completely new build with a new Ryzen 7800X3D CPU. What I tried so far:

1 - Bios flash back to versions 1.28, 1.24 and 1.04, all show the same error

2 - Tested the PSU on another PC, it works fine

3 - Tried with memory, and without memory, with cooler and without cooler

4 - CMOS reset

Nothing works still stuck at 00, PC won't boot or show anything. What else can I try? I'm thinking about asking for RMA.

Full list of components is:

PSU: Super flower leadex III 850W

CPU: Ryzen 7 7800X3D

MEMORY: 2X 16GB CORSAIR VEGEANCE DDR5

VGA: RTX 3070

But for now I'm trying with just PSU, MB and CPU. It should at least progress from 00 to another code.

Here is 2 photos of it. Testing with bios 1.28:

Please can someone help? I'm very frusted and sad with all this situation.

April 14, 2023 -

Yesterday I tried setting PBO through Ryzen Master. Not sure what I exactly did but it started to run a PBO optimizer which runs for about 40 min. Everything was working great temps were low nothing higher than 70c. I went to walk my dog and came back to a black screen and error code 00. It has happened before but I just shut it off a used the Clear CMOS which helped it boot back on. But now It won't post and All I have a is black screen, fans working everything powers on just that dreaded 00 code. I just put in my new 7800x3d CPU Friday.

Not sure what is going on anyone ever had this happen?
