ASUS 800-series boards are killing Ryzen 7 9800X3D chips, five dead CPU reports in two weeks

ASUS motherboards claim 5 Ryzen 9800X3D CPUs

The company remains silent.

At least five Reddit posts from the past two weeks describe AMD Ryzen 7 9800X3D systems that stop posting on ASUS AM5 boards, with owners reporting Q-Code 00 as the common endpoint. The board list spans B850 and multiple X870E models, so the reports are not tied to one SKU line.

Across these cases, the stories look similar after the failure hits. A system runs normally, then a reboot, sleep wake, or a normal desktop moment ends in a black screen and a board stuck at 00, sometimes alongside a DRAM status light. Owners describe the usual troubleshooting loop: CMOS clear, RAM swaps, PSU swaps, reseating, and USB BIOS flash attempts, with no change in behavior.

  • ASUS TUF B850M-PLUS WIFI: system stopped showing video after working for about two months; the poster says part testing pointed to a dead CPU.
  • ASUS X870E-E (ROG Strix): reboot hang, then error 00 ; the poster also mentions an accidental socket-pin bend afterward, which complicates the cause.
  • ROG Crosshair X870E: full system shutdown after two days, then no BIOS or display; the post reads like a platform failure, not a confirmed dead CPU.
  • ROG Strix X870E-E Gaming: black screen after sleep; the poster reports code 00 , and a repair shop claim of “over 20” similar cases.
  • ROG Crosshair X870E Hero: system froze after gaming, then code 00 ; the poster says a replacement CPU worked, and the owner is in contact with AMD.

Time to failure ranges from two days in one new-build report to over a year in another, and at least one owner says only EXPO was enabled, with no manual CPU overclock.

Earlier waves of 9800X3D failure talk centered on ASRock. The company later acknowledged that their BIOS applies incorrect settings and continues to release new BIOSes and replace broken units. The Reddit megathread now lists 157 cases involving the 9800X3D CPU alone .  ASRock has never recalled their motherboards, and they continue to launch new models, the latest being from this week .
