AM5 CPU Failure Thread

   Hi pcmoon, as I said in your reply to the Taichi White thread, I am afraid I don't
have availability info. If your country has a localization on the ASRock website
you can check the "where to buy" section specific to your country. There is a
small spherical icon at the top right of the website that allows you to pick
your region. Select the region nearest you and then click the "where to buy"
link and see if the board you are looking for is listed by any of them. 

For what it's worth, the X870e Taichi White edition is not available in 
Greece, Bulgaria or Romania yet at the time of writing this, 7th October 2026.
I suspect it will show up in local EU stores but I have no idea when I am afraid.

As for AM5 CPU failures, that is tough to answer satisfactorily. Will your CPU
die on you£ That I can't answer, it will depend on the CPU you get. Will your 
ASRock board kill it, that I can answer, no, it won't. Current failures are happening
across all manufacturers at more or less an equal rate. Talking about failures 
in this way makes it sound incredibly common, it isn't. AM5 9k CPUs have a higher
than normal failure rate yes but according to the available data, the failure rate
is still well within what is considered acceptable. Far more intel 14th gen CPUs
died for example. 

In the end, your warranty is your safety net and AMD is being very good with 
AM5 CPU RMA requests as a result of the initial issues the 9k series experienced. 

I hope this answers your questions

	Hello, I wanted to report the issue I experienced with my motherboard and AM5 CPU. Note: this is not a troubleshooting request. Both the CPU and motherboard have already been replaced under warranty. CPU: Ryzen 9 9950X3D Motherboard: ASRock X870 Steel Legend WiFi PSU: Seasonic Vertex GX-1200 The system worked normally for several months. It was used from November to February and again from June to September; I was away for about four months in spring, so the PC was not used during that period. It was stable under heavy load and gaming. The failure happened after the PC had been left in sleep/standby. When I returned, it would no longer POST. There was no display, the keyboard was not initialized, and the red CPU diagnostic LED remained lit. Clearing CMOS, BIOS Flashback, reseating/changing the RAM configuration, and checking the CPU/EPS power connections did not change the symptoms. The motherboard and CPU were both sent for warranty diagnosis. The retailer/service tested my motherboard with another CPU, and the board still would not POST. The motherboard was therefore considered defective. My original 9950X3D was also found to be defective and was replaced. In the end, both the motherboard and CPU were replaced under warranty. Unfortunately, I do not know the exact BIOS version. I bought the board in November 2025 and do not remember updating the BIOS afterward, so it was likely running the factory-installed BIOS from that production batch. I am posting this because most reports seem to involve a failed CPU while the motherboard remains functional, whereas in my case there was evidence that both components had failed. The exact failure mechanism is unknown.

	First of all, sorry to hear about your difficulties. Thanks for the report. It seems a number of failures have been tied to sleep/wake events. I am glad to hear your warranty replacements were processed without issue. Based on your description it sounds like your BIOS version may have been an earlier, vulnerable one. If you never updated it and purchased the parts in around November 2025 then it likely shipped with BIOS 3.40.

	ASRock X870 Pro RS WiFi + Ryzen 9 9950X £Sudden No POST on BIOS 4.10, still dead after 4.60 update Hello everyone, I would like to report another potential Ryzen 9000 / ASRock AM5 failure and share my experience for documentation. System specifications: - Motherboard: ASRock X870 Pro RS WiFi - CPU: AMD Ryzen 9 9950X - RAM: G.Skill Trident Z5 RGB 48GB (2£24GB), DDR5-7200 kit - PSU: ASUS ROG Strix 1000P Gaming 1000W - Cooling: Arctic Liquid Freezer AIO - BIOS at the time of failure: 4.10 - BIOS after troubleshooting: 4.60 Failure details: The system was assembled in early 2025 and worked normally for approximately 21 months. In October 2026, the computer suddenly stopped POSTing. Immediately after powering on, the red CPU and yellow DRAM diagnostic LEDs remain continuously illuminated. All fans spin, but there is no video output and no access to UEFI. Troubleshooting performed: 1. Tested both RAM modules in another PC £both work. 2. Tested each RAM module individually in slot A2 £no change. 3. Cleared CMOS £no change. 4. Updated BIOS from 4.10 to 4.60 using BIOS Flashback. The flashing procedure completed normally, but the system still does not POST. 5. Checked and reconnected all CPU and motherboard power cables. 6. Removed the dedicated GPU and tested the integrated graphics output. 7. Removed and visually inspected the CPU and AM5 socket. No obvious bent pins, burn marks or physical damage were found. Current RMA status: The CPU retailer has requested that I send the Ryzen 9 9950X for warranty inspection. I have also submitted a separate warranty claim for the ASRock X870 Pro RS WiFi motherboard and am currently waiting for the retailer's response. At this point, I cannot confirm whether the CPU, motherboard, or both have failed. My main concern: The failure occurred while running BIOS 4.10, not an early BIOS version. Updating to 4.60 did not restore POST. Given the previously reported Ryzen 9000 failures on ASRock AM5 motherboards, I am concerned about a possible motherboard-related electrical fault, although I have no evidence confirming this. Questions: - Has anyone experienced a similar failure with the X870 Pro RS WiFi and Ryzen 9 9950X£ - Have any Ryzen 9000 failures been confirmed on BIOS 4.10 or newer£ - Has ASRock identified any hardware-related causes beyond BIOS configuration issues£ - Is it advisable to test the motherboard's CPU power delivery before installing a replacement processor£ I would appreciate any technical feedback, especially from ASRock representatives or users who have received confirmed RMA results. I will update this thread once the CPU and motherboard have been inspected. Thank you.

	Hello NeoKris. Thanks for sharing the details of your failure. I will do my best to answer your questions but bare in mind I do not speak on ASRock's behalf, these are just my own thoughts/experience. - Your failure is pretty much textbook for 9k CPU failures. - CPU failures since BIOS 4.xx still occur but they are now occurring with the same frequency as failures on all manufacturer boards regardless of brand. - The issue is a weakness in Ryzen 9000 series IMCs that makes them burn out faster than 7k series. ASRock's initial higher failure rate was caused by overly aggressive settings in the earlier BIOS versions, aggressive settings that caused no issues with previous 7k series CPUs. Basically, the 9k series is pushing it's IMC to the absolute limit for performance gains over the 7k series. This is sadly just the way things are today. CPU architecture is being pushed harder than ever on top of increased circuit/transistor density and much smaller process nodes. While this yields higher performance and better efficiency it does mean that CPUs are not as robust as they used to be. All that said, failures are within what is considered industry standard. Intel and AMD's latest offerings have near identical failure rates as far as the most recent info I have been able to find. - It is unlikely there is any issue with the board given the nature of the issue. That said, many feel uncomfortable continuing to use the same board after a failure like this. Multiple techtubers have attempted to recreate failures, some even going as far as purchasing boards from 3rd parties that have experienced a CPU failure before, but none have managed to make a CPU fail, even on the "murder boards" they have tested with. At the end of the day, this is why warranty is important. If you have issues with your RMA you can reach out to AMD directly. Thanks again for the detailed information.
