r/ASRock on Reddit: X870e Nova & 9800x3d – "00" post code and no display output
January 24, 2025 -

Update 2: bios flashback to 3.10 helped to resolve the problem. hope the issue will be addressed in future bios updates.

Update 1: I was running BIOS 3.17 beta (someone who got that bios from Asrock support email posted it here on Reddit) when problems appeared. Then I tried 3.16, 3.18 beta and 3.15, for all 3 versions I was getting code 00. Now tried original BIOS 3.10 that my board came with (there's even a sticker "3.10" on a plate), and I managed to boot into BIOS.

I’m running into a serious issue with my ASRock X870E Nova motherboard and Ryzen 9 9800X3D after performing a CMOS reset. My system was working fine before, but now it won’t boot and is stuck on post code “00” with no display output (even from integrated USB4 and HDMI ports).

My Bluetooth wasn’t working in Windows (no bluetooth in device manager), and I read somewhere that a CMOS reset could fix it after connecting wifi antenna. After shutdown from Windows I pressed the CMOS reset button on the motherboard. After that, my system failed to boot with 00 on the debug postcode display. I tried to fix it by flashing multiple BIOS versions using BIOS Flashback, which appeared successful (flashing light blinked with increasing frequency and stopped as expected). But even after flashing, I still get 00, and my monitor gets no signal. I removed Nvidia GPU, SATA and NVME SSDs and left one RAM stick. Still "00" on the debug display. Placed RAM stick into 2nd slot instead of 4th (4th is the correct one in single stick setup) - got code AA 21. CPU heatsink is cold. NVME drive was warm. Used "bios flashback" button to flashback 3 different bios versions (3.15, 3.16 and latest 3.18 beta) - no effect, still 00 code.

What to do? Currently thinking either CPU or the motherboard died, maybe both. Is there anything else I could figure out before I go through RMA for either CPU or motherboard? I don't think repasting CPU and reattaching cooler could do anything since before first CMOS reset I didn't do anything with my hardware.

My setup:

* 9800x3d

* x870e nova

* Asus ROG STRIX 1000G 1000W

* CORSAIR Vengeance DDR5 64GB (2x32GB) DDR5 6000MHz CL30 CMK64GX5M2B6000Z30

* nvidia rtx 4090

* 990 pro & 980 pro nvme ssd

r/ASRock on Reddit: Computer suddenly not booting (X870e NOVA; Code stuck at 00)
June 30, 2025 -

I have reached out to ASRock CS, but wanted to ask here in case I am being stupid and missed something obvious.

I got the X870e NOVA back at the end of December and has been using it with the 9800x3D with no issues for half a year now. I know there has been lots of issues being discussed, but I was hoping I wasn't going to hit anything since it has been fine for so long now.

I put my computer to sleep this morning and when I came back from work, the computer didn't resume. Restarted it and see that the code is stuck at "00." Googling and other post seems to say it is a CPU issue, so I reseated the CPU (no external damage, no bent pins) and still not working. I was on BIOS 3.15 or 3.16, and tried updating to 3.30, which didn't fix it.

Again, seeing if someone else got something else I missed, or if I need to wait for ASRock. Or if this may be a CPU issue (don't have another CPU to test with) and I'm out of luck...

r/ASRock on Reddit: X870e nova 9800x3d "00" code on boot
April 5, 2025 -

Edit 2: SOLVED THE ISSUE. Turns out I'm an idiot (albeit a very happy one now) because I renamed the flashback folder instead of the file... Sucessfuly flashed to 3.2 now and it boots normally. Feel free to take post down but figured I would leave it up so whoever saw can get an update.

System is about a week old and seeing this code now and it won't POST. stayed on the 3.15 bios since it seemed stable until now, tried flashing to 3.2 and 3.1 and no luck on either. Tried clearing cmos as well after the flashbacks didn't work.

Have been aware of all the issues going on with this combo and it seems I am unfortunately one of the unlucky ones to be affected too. Didn't turn on EXPO or any OC settings in bios yet, just adjusted my aio pump speed and turned off bt and wifi since I didn't need them.

Any other troubleshooting tips I should try? I dont have another am5 mobo to try the cpu with. Not sure if its the cpu or mobo, but I'll be reaching out to both Asrock and AMD in the meantime.

Edit: RAM I am using is QVL listed 2x32gb F5-6000J3040G32GX2-TZ5NR and the cpu batch is 2448PGE. Not confirmed dead yet I suppose but just posting the info here for anyone curious.

r/ASRock on Reddit: Sudden codes 37, 15 and 00 on x870e nova
May 23, 2025 -

Hello. I need some help. Suddenly getting wietd codes and can't figure out the reason. Didn't do much to cpu (except reposting). Looks nice and clean. Socket as well. But can't boot. We'll, I can but only with old memory kit (around 4800 iirc). The main one refuse to boot in any slot/configuration Ordered a new one (thought maybe ram was dead) - same issue, can't boot. Usually I see codes 00, 15 or 37. Couple of times we're 0d and the rest are random. The fact that I can normally boot with the old kit (and play) tells me that cpu is fine. Or there is something I didn't think of? I tried to run memtest on old slow kit - all went smoothly (does that imply that controller is also fine?)

CPU is 9800x3d and it plays just fine with slow memory but not with 6000.

Find elsewhere

January 29, 2025 -

Update 2025-01-29: Got my hands on another 9800x3d and the system booted just fine. Looks like some of these CPU's are defective somehow. No visible damage on the unit. Already in the process of sending to AMD for RMA. Hopefully they get me a replacement with no complaints.

I updated my bios to 3.18 the other day. Everything went fine, was booted into Windows and playing games on it for hours. System booted 3 or 4 times since the bios update no crashes or apparent instability.

Last night before I went to bed the system hard froze I had to flip the PSU off. When I tried to boot I just get 00 code. Attempted to flashback to 3.10 (original bios) which seemed to be successful, but still 00 code.

I'm assuming my CPU is dead from similar reports here. Will be trying to order another to put in and confirm the issue...

r/ASRock on Reddit: 870E NOVA / 9950X3D - 03 and 00 codes this morning
February 16, 2026 -

Have had this board + 9950X3D running without issues from March 2025 until yesterday when I went to turn on the PC. Wouldn't boot with a code of 15 then 03. I reset and power cycled and it booted right up. Ran all day, shut down last night.

This morning, same 03 code - power cycled a few times and get code 00. Removed all USB devices and tried removing and booting off one stick of ram, and also a spare PSU - same result. I hadn't updated the bios since march of last year so I flashback the newest one and I'm still getting the same code.

I wasn't aware of any ongoing issue until this morning. Is my CPU probably dead?

r/ASRock on Reddit: Nova X870e stuck on code 15
October 22, 2024 -

EDIT: for those who find this in the future, it turns out that the chipset drivers weren’t installed automatically and the RAM worked after updating those.

Hey everyone, I am building a new PC after being out of the game for a while. I have:

X870e Nova Wi-Fi

7800x3d

2x32gb Trident Z neo 6000 ddr5 (the 3040 one)

Anyway, I boot it up the first time and it runs great. I get windows and everything installed with no issues. I go to restart my computer and set the EXPO profile and save. My computer goes to reboot and stays on code 15 for a while, flashes a few random codes, then back to 15. It repeated this for over an hour. I finally shut it down, reset the CMOS, and it booted up and worked perfectly.

Has anyone run into this issue before? Is it a problem with the new motherboards? Any tips for getting it to work?

Thanks again!

Hello, running a new build with x870e nova and a 9800x3d. The mobo codes slowly keep changing through the 30s and 40s constantly. Never seen this before. Anyone else? Everything is working fine.
