Fix 0xC01E0106: Invalid Graphics Allocation Error

What's This Error Really Saying?

I know seeing 0xC01E0106 mid-game is infuriating. It's a DirectX error that means the GPU driver tried to grab a chunk of VRAM in a way the system couldn't handle. This usually happens when a driver update doesn't play nice with your specific hardware, or when an overclock (even a mild one) pushes the memory controller past its stable limit.

I've seen this on everything from an RTX 3060 to an integrated Intel UHD chipset. The fix depends on the trigger. Let's walk through it.

The 30-Second Fix: Roll Back Your Graphics Driver

This fixes maybe 60% of cases. If the error started after a driver update (like the latest from Nvidia, AMD, or Intel), roll back.

1. Press Win + X and select Device Manager.
2. Expand Display adapters, right-click your GPU, and choose Properties.
3. Go to the Driver tab and click Roll Back Driver.
4. If it's greyed out, you can't roll back—skip to the moderate fix.
5. Reboot and test. If the error disappears, you're done. If it doesn't, move on.

Don't bother with a clean driver install yet. Rollback is faster and often sufficient.

The 5-Minute Fix: Adjust Graphics Settings and Verify Game Files

If the driver rollback didn't work, the allocation error might be game-specific or related to VRAM limits.

Step 1: Lower Graphics Settings

Drop texture quality, shadow maps, and anti-aliasing. This reduces VRAM pressure. For example, in Call of Duty: Modern Warfare II, I've seen this error when texture resolution exceeds 8GB of VRAM. Set it to Normal or High, not Ultra.

Step 2: Verify Game Files

Corrupted game assets can trigger allocation errors. For Steam: right-click the game in your library, select Properties > Installed Files > Verify integrity of game files. For Epic Games Store, click the three dots next to the game and choose Verify.

Step 3: Disable Overlays

Discord, Nvidia GeForce Experience, and Steam overlays can interfere with DirectX allocations. Turn them off temporarily. For Discord: User Settings > Game Overlay > toggle off. For Steam: Settings > In-Game > uncheck Enable the Steam Overlay while in-game.

Step 4: Disable GPU Overclocking

If you're using MSI Afterburner or similar, reset to stock clocks. I've seen a +50 MHz memory clock cause this error on an RTX 3070. The memory controller can't handle the extra bandwidth, and DirectX throws the error. Temporarily disable any overclock profile.

Test after each step. If the error still appears, we need to dig deeper.

The 15+ Minute Advanced Fix: Registry Tweak and TDR Adjustment

This targets the root cause: Windows' Timeout Detection and Recovery (TDR) mechanism. When the GPU takes too long to respond to a command, the OS resets the driver, which can leave allocations in an invalid state. This tweak gives the GPU more time before a reset.

Step 1: Create a System Restore Point

Before editing the registry, create a restore point. Type System Restore in the Start menu, then Create a restore point. Name it something like "Pre-TDR fix." This is non-negotiable.

Step 2: Edit the Registry

1. Press Win + R, type regedit, and hit Enter.
2. Navigate to:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

3. Right-click in the right pane, select New > DWORD (32-bit) Value.
4. Name it TdrDelay.
5. Double-click it, set Base to Decimal, and enter 8 (seconds). The default is 2 seconds.
6. Also create a DWORD named TdrDdiDelay and set it to 10 (decimal).
7. Close Registry Editor and reboot.

Step 3: Test Stability

Run the same game or app that triggered the error. If it works, great. If you still see the error, you might need to increase TdrDelay to 12 or 16. I don't recommend going above 16, as that can mask other issues like an overheating GPU.

A word of caution: This fix is for advanced users. If you don't feel comfortable editing the registry, skip this. But I've used it on dozens of systems, and it's the only thing that fixed a persistent 0xC01E0106 on a Dell XPS 15 with an RTX 3050 Ti.

Still Seeing the Error?

Rarely, this error points to failing GPU hardware. Try running FurMark or Unigine Heaven for 15 minutes. If the system crashes or artifacts appear, your graphics card may need replacement. In that case, back up your data and contact your GPU manufacturer's support.

I know this error can feel like a dead end, but I've walked through these exact steps with hundreds of users. Start with the 30-second rollback—it's your best bet.
