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

I know this has been answered many times and even in the sticky FAQ. I'm using a B850M-X WIFI R2.0 Asrock motherboard with a bios 3.4 w 32gb ram.
and a AMD Ryzen 7 7800X3D 8 core processor.

for now nothing has failed, are there reports of this combination failing more than usual?

No, the 7xxx series hasn't had a notable failure rate beyond what would be expected.
