Image and text guide

This guide will walk you through the entire process of setting up the Stark 75t DMA card. It includes instructions for physically installing the card, setting it up on both the primary and secondary computers, and completing the driver installation to ensure proper functionality.

This card does not come with custom firmware.

Hardware Installation

Power down your main PC and ensure you disconnect the power cable for safety before proceeding. To set up your DMA hardware, identify the motherboard of the PC where you plan to use your DMA card to read memory (referred to as the main PC). Locate the farthest PCIe slot away from the primary GPU slot; this will typically be the ideal location for your DMA card setup to avoid interference with your GPU. Alternatively, the primary GPU slot itself can also be used if necessary. However, for the purpose of this guide, we will focus on using the farthest PCIe slot to optimize the configuration of your DMA hardware.

Carefully install the DMA card into the PCIe slot as shown in the image

Reconnect the power cable to your main PC and turn it on. Next, take the USB-C to USB-A cable included with your DMA card and connect it to the JTAG port like pictured below. Plug the other end of the cable into a USB 3.0 or higher port on your second PC. 

If you notice that no lights are illuminated on your DMA card when the computer is powered on, as demonstrated in the image below, it may indicate that the card is inactive. To resolve this, locate the kill switch button on your dma. While the computer is still running, press the kill switch button once. This action should activate the DMA card and turn on its lights.

BIOS Configuration

The BIOS settings outlined below are only required to be adjusted on the computer where the DMA card is installed. No changes are needed to the BIOS of the second pc.

REQUIRED (AMD) Disable IOMMU

REQUIRED (AMD) Disable Virtualization & SVM

REQUIRED (INTEL) Disable Virtualization

REQUIRED (INTEL) Disable VT-d

More Optional BIOS Settings:

Driver Install's

Turn on both the main PC and the second PC to begin the DMA driver process. Make sure the USB-C to USB-A cable is securely connected to the JTAG port on the DMA card. Then, plug the other end of the cable into a USB 3.0 or higher port on your second PC.

Follow the video below on your second pc.

After restarting your second PC, connect the USB-C to USB-A cable to the data port on your DMA card. Once connected, wait for approximately 5-10 seconds to allow your system to recognize the DMA hardware. Next, open the Device Manager on your second PC to verify the setup. If the setup was completed successfully, you should notice a “FTDI FT601 USB 3.0 Bridge Device” listed under the Universal Serial Bus Controllers section. If the device does not appear, or if you see a yellow triangle icon next to it, this indicates an issue with your DMA drivers. To troubleshoot, refer to the instructional video below.

Firmware Flashing

Flashing the DMA firmware is a process that should always be performed on a secondary PC, not your primary computer. To start the DMA setup, ensure that your DMA card is properly connected to the JTAG port before proceeding.

DMA Firmware Testing

This will cover the general usage of the lone dma test tool. It is a good rule of thumb to always use the tool before attempting to load any software or after flashing a new firmware just to confirm everything is working as it should. 

Everything in this guide is done on your 2nd PC. Plug into the DATA port on the dma card. Download and extract the archive where you wish. Run the “lone-dma-test” application.

If your test is successful you should see something similar to below

Speed Test Results:

  • <4000 = Fail
  • 4000+ = Acceptable
  • 5000+ = Good
  • 6000+ = Excellent

Throughput Test Results:

  • <125 = Fail
  • 125+ = Acceptable
  • 150+ = Good
  • 200+ = Excellent

Troubleshooting

Failed to retrieve Physical Memory Map

  • Troubleshoot your USB Connection.
  • If all else fails, re-install windows on your Game 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
    it in the folder. This is an ‘offline’ symbols dump.

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 Game PC per the setup steps.
  • Troubleshoot your USB Connection.
  • Last resort: Re-install windows on Game PC.

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/Sec.
  • 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.
  • 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).

DMA Software – Not loading up, entities disappearing or not showing, other anomalous
behavior:

  • This is most commonly caused by Paged Out Memory.
  • When your system / target process are under High Memory Pressure, assets in
    memory may get shifted to your Page File.
  • The Page File is a file located on your hard drive that contains low priority / less commonly accessed items.
  • Since the Page File is located on your hard drive, your DMA Card cannot read from it.
  • This can cause undefined behavior in many DMA Software(s), and lead to a lot of frustration.
  • This is most commonly resolved by installing additional System Memory (RAM) in your Game PC.
  • You can also disable the System Page File in Windows on your Game PC (Not Recommended: Your system can BSOD if Memory Commits exceed available memory).
