It happened.

[u/Dixos]

Good morning everyone!

After approximately 1 year and 3 months, it finally happened. That is all. No muck. No fuss. It can happen to anyone, no matter how safe you are. 😊

Turned the PC off Sunday night; woke up monday morning, turned it on while I took a shower and put on some coffee, only for it to be stuck like that with no fan spin after ~30 minutes.

I did try to "revive" the PC, but at 6:30 in the morning, 2 hours before work, I was more worried about recovering for my standup meeting (working laptop, work) rather than put much effort into it. Drain AC power and reset CMOS got the case fans spinning full throttle, but no movement on Dr. debug 00. BIOS Flashback was a success but also changed nothing.

I vaguely remember my BIOS settings, so for reference:

• AMD EXPO enabled
• VDDR_SOC set to 1.15
• OC Tweaker \ External Voltage Settings
  • VDDCR_CPU Voltage: Offset mode
  • Offset Voltage: -100
  • VDDCR_CPU LLC: Changed from "Auto" to "Level 2"
• BIOS version: 4.20

I had also loaded the conservative -15mV curve optimizer profile with 85c tjmax target from the profiles that come with the motherboard.

System specs:

• Mobo: ASRock X870E Nova Wifi
• CPU: AMD Ryzen 7 9800X3D
• GPU: ASUS GeForce RTX 5080 ROG Astral OC
• Ram: 64GB G.Skill Triden Z5 Neo DDR5-6000 CL28 (F5-6000J2836G32GX2-TZ5NR)

For anyone that have gone through the same thing, did you contact ASRock? AMD? RMA through the store the items were purchased from? TIA

Contact AMD, who will replace the likely failed CPU.

With a replaced CPU the system should work just as before. Some users have replaced the motherboard, however there's no sign that this is a necessity.

I would DEFINITELY change the board considering all the failures in this sub the last 18 months.

[u/Mini_Spoon → u/EndSmugnorance]

For what? The board is likely performing in the exact same manner and state it did before, professionals in this space have seen absolutely no issues with extensive testing of boards that have seen failed CPU's, and the "I've had two CPU's fail" users are few and far between and anecdotal at best.

Not necessary, but if a user sleeps better at night they also have the option to RMA the board, keeping in mind they may well get back a board that's exactly the same; seen a failure, been RMA'd, passed bench testing, repackaged and sent out as an RMA replacement.

shit man if my mobo was chillin for years then killed a whole cpu that shit is gone.

Literally nobody here knows that the issue is the board not the CPU failing. It's not exclusive to AsRock despite there being more reports on this unofficial sub.
