[Solved] How to fix DXGI_ERROR_DEVICE_HUNG crashes & Unreal Engine 5 shader compilation crashes on DDR5 / 13th-14th Gen & AM5

If your games are crashing to desktop during the initial "Compiling Shaders" screen with an "Out of Video Memory" error (even on a 16GB/24GB GPU!) or mid-game with DXGI_ERROR_DEVICE_HUNG, here is the verified 3-step checklist that solves 95% of cases:

1. BIOS Microcode Update: Ensure your motherboard BIOS is updated to the latest AGESA (for AM5 DDR5-6000 stability) or Intel 0x12B microcode with "Intel Default Settings" power profile enabled—Oodle decompression during UE5 shader compilation exposes unstable CPU ring/core voltages immediately.

2. 4-DIMM DDR5 Downclocking: If you populated all 4 RAM slots with DDR5, XMP/EXPO at 6000–6400 MT/s will often fail memory training or throw silentWHEA errors under GPU heat. Use 2 DIMMs in slots A2/B2 or step frequency down to 5600 MT/s.

3. Clear DirectX & GPU Driver Shader Cache: Run Windows Disk Cleanup -> DirectX Shader Cache after any major game patch or GPU driver update using DDU.

Step 1 saved my Black Myth: Wukong and S.T.A.L.K.E.R. 2 installs! Everyone assumes "Out of Video Memory" during shader compilation means a faulty GPU, when it is actually Oodle Kraken decompression failing a CRC check on the CPU.

Pinning this checklist! Also worth checking that Windows Virtual Memory (Pagefile) is set to "System managed size" on your primary NVMe SSD—disabling the pagefile even with 32GB RAM causes immediate crashes in DirectX 12 commit allocations.
