Troubleshooting
This page explains how to troubleshoot issues with your DMA Card.
ERROR - [FAIL] VMM INIT FAILED.
The most common cause of this error is your DMA Card/Connection is ‘hung’. This most commonly occurs after your main PC does a fast reboot, or if your main PC was previously in sleep mode
Shutdown your main PC (do not reboot), wait 15 seconds and power it back on
This should resolve this issue 99% of the time
ERROR - DEVICE: FPGA: ERROR: Unable to connect to USB/FT601 device [0,v0.0,0000]
Make sure you installed the FTDI Driver on your 2nd PC
Make sure you are plugged into the DATA PORT on your DMA Card
Failed to retrieve Physical Memory Map!
Troubleshoot your USB Connection
If all else fails, re-install windows on your main PC
[SYMBOL] Offline symbols unavailable - file 'info.db' not found.
This means that PCILeech was unable to download symbols from the Microsoft Symbol Server. This assists PCILeech in reading memory from your Game PC System
Make sure you unzipped the folder and all files
Make sure symsrv.dll and dbghelp.dll are present in the folder
Make sure you have internet connectivity and your firewall(s) are not blocking any connections
If all else fails, you can download the latest info.db file from the MemProcFS repository (https://github.com/ufrisk/MemProcFS/releases win-x64), and include
FPGA: TINY PCIe TLP Algorithm auto-selected!
This indicates that your DMA Card is operating at lower speeds. This can sometimes be due to a firmware issue, or more commonly a poor usb connection
Make sure your USB Cable is seated securely on both ends. Try different USB Port(s)
[CORE] Initialization Failed. Unable to locate valid DTB / Unable to auto-identify operating system.
Make sure you made the BIOS Adjustments on main PC per the setup steps
Troubleshoot your USB Connection
Last resort: Re-install windows on main PC
DMA Test Tool - Test Result: FAIL / General Failures
If the DMA Test is giving you a failure message, it is most commonly due to your speed/throughput being too low.
Speed under 4000 Mem/s
Throughput under 125 MB/s
This is most commonly due to a poor USB Connection:
Make sure your USB Cable is a data-rated (not charging-only!) USB 3.0 Cable, and is securely seated on both ends (DMA Card / Radar PC).
On your Radar PC go into Power Plans and set your Power Plan to High Performance. This can improve CPU / USB speeds
Try different USB Ports / USB Cables. iv. Keep playing with it! Most people resolve slow speeds by re-seating their DMA Card, reseating the USB Cable, and/or sometimes the DMA Card bracket may get in the way of the USB Cable fitting securely
If your Radar PC is significantly below recommended specs, this can diminish DMA Speed/Throughput
This can be less commonly caused by the Firmware on your DMA Card.
Some Vanguard / Faceit ‘bypass’ firmwares will reduce the speed/throughput of your card
In some cases DMA Software may still run fine with lower speeds/throughputs (particularly if you are close to the cutoffs).
We recommend running a Speed Test for ~360 or more seconds, and looking for any ‘drop outs’. If the connection is stable you may be fine even if you are getting reduced speeds
