i bought the B850 PRO RS and 9900x combo the 04.29.25 and had no issues, until recently, followed steps from this forum, and reddit, other forums. Red & Orange light not budging at all.
The motherboard killed the cpu.
Luckily i had a pal with the same chipset AM5, Msi Edge ITX and my cpu gave the same error, cleared cmos, let it run for 30min+. put his 9800x3d back and no issues.
In summary. RMA everything and get something else rather than Asrock for now.]]> Mon, 04 May 2026 05:29:59 +0000 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=201368&title=b850-pro-a-unstable-post-issues#201368 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=199201&title=b850-pro-a-unstable-post-issues#199201 Author: JustRick

Hi all! I found the culprit for me!

I made a post about it on Reddit for those interested. For me it was a bug where values of Competitive/Aggressive DRAM Profiles weren't properly reverted when switching back to AMD AGESA Default profile:

Hi Cameron.

I'm since about 3 weeks been experiencing the same issue as described by others (owned this system since january).

It is in fact not hanging at the memory training, as it goes past the blinking DRAM light, but gets stuck once it's at the green BOOT status light.]]> Sat, 11 Oct 2025 03:58:45 +0000 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=199192&title=b850-pro-a-unstable-post-issues#199192 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=199000&title=b850-pro-a-unstable-post-issues#199000 Author: cameron

If the red and yellow lights come on and stay on, do the following:

1. leave it on
2. drive to starbucks
3. order a coffee
4. wait for the coffee
5. sit down and drink the coffee while watching every video on tiktok
6. drive back home
7. check to see if the red and yellow lights are still on

I've done a few ASRock builds lately, and the first time they power up, they go through some sheep counting exercise that takes forever. Memory testing and whatnot. It may take 5 minutes or more to finish. Just ignore it for a while and see if it actually finishes.

Every single time I do one of these builds, and hit the same exact annoying problem, I wonder if I did something wrong and I reseat the CPU etc. and then it dawns on me that probably nothing is wrong and it's just this stupid first-flight test it always does.

After one successful boot, this usually won't happen again until you change some hardware.]]> Wed, 17 Sep 2025 06:14:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=199000&title=b850-pro-a-unstable-post-issues#199000 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=196715&title=b850-pro-a-unstable-post-issues#196715 Author: Olsentw

The only work around I have at the moment is to press the reset button on my case after it is stuck on the green light, then it boots normally.]]> Fri, 06 Jun 2025 08:41:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=195618&title=b850-pro-a-unstable-post-issues#195618 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=195523&title=b850-pro-a-unstable-post-issues#195523 Author: kinsher

No resolution for me at the moment. I contacted Asrock support and they suggested resetting the BIOS to factory defaults, but this did not solve the issue. They said they would contact HQ.

The only work-around for me is to press the reset button once it gets hung on the green light, then it boots normally.

My system is a new build and only ran on 3.20 for a few weeks so I don't think there has been any damage to the CPU.]]> Wed, 04 Jun 2025 02:23:01 +0000 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=195523&title=b850-pro-a-unstable-post-issues#195523 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=195478&title=b850-pro-a-unstable-post-issues#195478 Author: lewin

I'm having the same issue at the moment, no POST with a green status LED using a B850 LiveMixer and a 9600X. Did you guys have any luck solving the issue?

I am now wondering if these events was caused by Asrock board frying Ryzen 9000 cpus.I ordered new mobo Asus prime b850m and cpu ryzen 8600g to further narrow it down. I'll keep you guys posted when these arrived.]]> Sun, 01 Jun 2025 02:42:23 +0000 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=195451&title=b850-pro-a-unstable-post-issues#195451 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=195448&title=b850-pro-a-unstable-post-issues#195448 Author: kinsher

I have the exact same problem since updating to 3.25.

Asrock B850 Pro RS. Ryzen 9800x3D.

From a cold boot the system stays with the yellow-green light on. No display output, no caps lock. If I press the reset button the system then boots as normal. It happens every time the system is turned on from a power-off state.]]> Sun, 01 Jun 2025 01:46:05 +0000 https://forum.asrock.com/forum_posts.asp?TID=97496&PID=195448&title=b850-pro-a-unstable-post-issues#195448
