\*\ ***Issues**

- EVE Online game launch from client fails to launch with Error: Exit code: 3221225477 (0xC0000005) – Access violation, game also crashes unexpectedly
  - Support states possible instability with 14/15th generation Intel CPUs

- Occasional operating system error “The instruction at [address] referenced memory… could not be written” at system shutdown
- System-level memory access errors on shutdown
- Random operating system freezes
- **Hardware**
  - Intel Core i9-14900K
  - Motherboard: ASUS Z790 GAMING WIFI 7

- **Troubleshooting completed**
  - updated graphics drivers
  - installed a Samsung 990 PRO NVMe for gaming bandwidth, F: drive
  - repaired system files with DISM and sfc /scannow
  - checked C: drive health, good
  - checked RAM health, good
  - ran DISM /Online /Cleanup-Image /RestoreHealth
  - disabled Antivirus by excluding game folder
  - installed Visual C++ runtimes (x64 + x86)
  - disabled background interference (Razer, Norton, Defender cache exclusions)
  - Game level troubleshooting
    - cleanly installed **EVE** on a high-speed, isolated gaming drive
    - deleted %LocalAppData%\CCP and %AppData%\CCP
    - verified and/or moved Shared Cache to NVMe  
\*\*\* Solution\*\*

  - Updated motherboard BIOS to latest revision
  - Within BIOS
    - AI Tweaker
      - Performance preferences = Intel default settings
      - Intel default settings = performance
      - AI clock tuner = manual
      - BCLK frequency = 100
      - ASUS multicore enhancement = disabled

    - Advanced\CPU Configuration\CPU power management control
      - Intel turbo boost = disabled
      - Turbo mode = disabled
      - Dual tau boost = disabled

**After applying the solution, the game runs stable with one or eight clients simultaneously. Hope this helps.**

Thank you very much for this. I had a similar issue with an I7 - 14700K and the BIOS adaption worked for me as well. Seems to run stable for the rest of the system aswell even with fixed clock speeds.
