Install Runtime (Windows)#

Important

Make sure you have Visual C++ Redistributable installed before running the MemryX Installer.

You can download the latest from Microsoft here.

The Windows Driver and C++ Runtime for MX3 are installed using the MemryXInstaller.

System Requirements#

Any Windows 10 or Windows 11 PC with a relatively recent Intel/AMD processor (2014 or later) should work.

Note

Please be sure to setup the hardware before installing the driver and the runtime tools.

Installation#

  1. Download the MemryXInstaller.

  2. Right-click on the file, and select Run as administrator.

  1. Restart your PC to complete the installation.

Check It Worked#

After restarting, first verify that the driver is loading successfully. Assuming you’ve inserted the MX3 M.2 module (see Install Hardware), open Windows Device Manager, you should now see MemryX AI Accelerator connected:

Verify the installation by running the following command:

acclBench --hello

You should see the following output:

Hello from MXA!

Device ID | Chip Count |  Freq | Volt
----------|------------|-------|-----
        0 |          4 |   600 |  700

If the MXA is not detected, run the following command in PowerShell as administrator and try again:

Restart-Service -Name "MxaManagerSvc"

Firmware Troubleshooting#

If the device shows up in Device Manager, but benchmark tools or applications fail, you may need to update the firmware.

Error Message#

In particular, if you see an error similar to this:

Driver required firmware anti_rollback cnt >= X

This indicates that the firmware on the device is out of date and needs to be updated.

How to Update#

To update the firmware, make sure you have the latest MemryXInstaller already installed.

Then, open Command Prompt or PowerShell as administrator and run the following command:

"C:\Program Files\MemryX\tool\update_flash_tool\pcieupdateflash_win.exe" -f "C:\Program Files\MemryX\driver\cascade_4chips_flash.bin"

Upon success, restart your computer and try running again.
