Troubleshooting

❌ [FAIL] VMM INIT FAILED.

Cause: Your DMA card or connection is "hung," often due to a fast reboot or system waking from sleep.

Fix:

  • Fully shut down your Game PC (do not reboot).

  • Wait 5–10 seconds, then power it back on (a cold boot).

  • This resolves the issue 99% of the time.

hashtag
❌ FPGA: ERROR: Unable to connect to USB/FT601 device [0,v0.0,0000]

Cause: FTDI driver not installed or incorrect port used.

Fix:

  • Make sure the FTDI driver is installed on your Radar PC.

  • Confirm you are using the Data Port on the DMA card (not the power-only port).

hashtag
❌ Failed to retrieve Physical Memory Map!

Cause: Unstable or faulty USB connection.

Fix:

  • Reseat your USB cable on both ends.

  • Try a different USB 3.0 cable and USB port.

  • As a last resort, re-install Windows on your Game PC.

hashtag
❌ [SYMBOL] Offline symbols unavailable - file 'info.db' not found.

Cause: PCILeech cannot retrieve symbol data for memory interpretation.

Fix:

  • Ensure the tool was unzipped completely.

  • Check that both symsrv.dll and dbghelp.dll are in the same folder.

  • Verify you have active internet and no firewalls are blocking access.

  • Still stuck? ➤ Download latest info.db manuallyarrow-up-right and place it in your tool folder.

⚠️ FPGA: TINY PCIe TLP Algorithm auto-selected!

Cause: DMA card running at lower speeds due to poor USB connection or firmware.

Fix:

  • Check USB cable is firmly connected on both ends.

  • Try a different USB port.

  • In some cases, outdated or restricted firmware may reduce speed.

hashtag
❌ [CORE] Initialization Failed. Unable to locate valid DTB / auto-identify OS

Cause: Incorrect BIOS settings or unstable USB link.

Fix:

  • Review and apply all required BIOS changes on your Game PC.

  • Double-check USB cable stability and port selection.

  • As a last resort, re-install Windows on the Game PC.

❌ DMA Test Tool – Test Result: FAIL / General Failures

Cause: Speed or throughput below operational threshold.

📉 Common Triggers:

  • Speed under 4000 Mem/sec

  • Throughput under 125 MB/s

🛠 Fixes:

  1. Use a USB 3.0 data-rated cable (not charging-only).

  2. Make sure cable is seated securely.

  3. Switch to High Performance power plan on Radar PC.

  4. Try different USB ports and cables.

  5. Reseat the DMA card in its PCIe slot.

  6. Ensure bracket isn't interfering with USB connection.

  7. Check that your Radar PC meets system requirements.

  8. Some firmware (e.g., Vanguard/Faceit bypass) may cause reduced speed.

🧪 Recommendation: Run the DMA speed test for ~360 seconds to check for connection stability (dropouts). If stable, slightly low speeds may still work fine.

❗ DMA Software: Not Loading / Entities Missing / Glitchy Behavior

Cause: Paged Out Memory — the target process's memory is moved to the page file due to high memory pressure.

⚠️ Why This Matters:

  • DMA cannot read from the Windows page file, leading to undefined behavior in cheat/radar software.

🔧 Fix:

  • Install more RAM in your Game PC.

  • (Optional) Disable the System Page File in Windows (Not Recommended: May cause system instability or BSOD if memory is exhausted).
