The quick fix that stopped Call of Duty from crashing on my PC

22

Black Ops 6 and Warzone kept bailing to desktop with a DirectX pop up or a vague “verify and repair” loop. Drivers were current, files were clean, temps were fine. The culprit turned out to be memory instability. Two minutes in the BIOS solved it.

TLDR

Most COD crash loops on otherwise healthy rigs come from marginal RAM settings. Disable your XMP or EXPO profile and test. If the game stabilizes, re enable memory at a slightly lower speed or keep the safer setting.

Why RAM breaks COD

COD engines hammer VRAM and system RAM with big shader caches and streaming assets. If your DIMMs are pushed by aggressive XMP or EXPO timings, tiny errors trigger DirectX faults that look like file corruption. The game is innocent. Your memory training is not.

The two minute fix

1. Enter BIOS
   Restart and tap Delete or F2 during boot.
2. Turn off XMP or EXPO
   Set memory to Auto or default JEDEC speed. Save and reboot.
3. Test the game
   Play for 15 to 30 minutes. If crashes vanish, RAM settings were the cause.

Optional fine tuning

• If you want some speed back, re enable XMP or EXPO then downclock one step. Example: 6000 to 5600 MT s.
• Keep command rate at 2T if available.
• Update to the latest motherboard BIOS for improved memory training.
• If issues persist, run Windows Memory Diagnostic or MemTest86 and try another DIMM slot pairing.

Extra stability checks that help COD

• Shader cache reset inside COD settings after big patches.
• GPU driver clean install using the vendor’s tool.
• Page file set to System managed on the OS drive.
• Background overlays off while testing.
• Power plan on Balanced or High performance, not a low power custom.

What worked for me

Disabling EXPO fixed crashes immediately. I later re enabled it and lowered the memory speed one step. Frames were unchanged in game, stutters disappeared, and the DirectX gremlin retired.
